Best kit money can buy

This kit includes everything I needed for my 4-channel JL Audio amp. I love it. The look of the fuse holder is awesome and the braided cable protector is great under the hood too. The RCAs worked like a charm and I had plenty of speaker wire included. No complaints.

great

Have not installed yet but it seems to be everything it claims to be. Did recomend itnto a friend but he didn't listen and spent way to much for a kitat a local best buy. Did a lot of research before I bought this kit and it looked like the best value for my hard earned money. Having not yet installed is why I didn't go all five stars. Soon it will be going into my 89 olds custom cruiser with 4 12s....

Great Amp Kit

This is a high quality 4g amp kit for a great price .... nice 100 amp fuse box

Awesome kit!!!

This wiring kit is the best I've used so far. It bends very easy in tight places and this is the size wire that I actually paid for. Don't waste $ on cheaper brands...NVX is AWESOME!!!

Great Complete Package

I replaced all speaker wiring in my car with this kit. The quality of all the wires is very good. NVX is nice quality!

great product

This kit is very good and great quality. I would recommend this product for basic and some advanced systems.

Top of the line kit at decent price

This kit has everything and is as good as you can buy. Better than jl, Rockford, stinger, and kicker. At a price less than or equal to those mentioned. True spec, silver tinned ofc

Quality Amp Kit

This amp kit is high quality. Don't expect sound hiss or whining from you audio system if you use this kit. As long as you wire everything up right and run your wires properly, then this kit is the best for the money and you'll like the quality. High quality copper makes a big difference in sound quality and proper power distribution.
NVX deserves a pat on the back for making this one. Good job.

Nice amp kit.

The speaker, power, and ground wire are exceptional. Very flexible, easy to run, no smell, true to size and just look and feel nice. The RCA looks good too but the ends fit on my amp a little loose. All in all, the kit works perfectly and looks good

Great product

This was a great kit to deal with and would recommend it to all of my friends. This was a really good quality kit that will also look good in any install .

Don't cheap out

I hesitated to go with a true amp install kit until I matched this up with a Rockford Fosgate amp that called for a 4 gauge install kit. Just the ease of installation was well worth the price. For 4-gauge wire this is really flexible and easy to snake through the dash and under the hood. Don't believe me? Go to a big box hardware store and just see how in-flexible 4-gauge copper house wire can be. Plus, the difference in the protective jacket of the two is night and day. The NVX kit is a winner hands down. I didn't need to use everything in the kit. Some of the hardware bits I passed up. But I used all the rest. Glad I bought it.

A++

Great value and excellent product no doubt. Very flexible yet sturdy wires with lots of metal not filler jacketing. Worth the money no question.

First time

I was impressed with the quality and will use them every time .

Great product.

Materials are first class. This is the way to go. No cheap stuff. Everything you need for your install

Great Quality

This is a great kit. The wires are great quality and it comes with shrink wrap and fuse holder. Even the speaker wire is great. If you're installing an amp, these are the kits you need.

This big 3 is a very nice setup and I haven't installed it just yet. Great quality wire and you can never go wrong with this product. The price is ok just a little over my budget lol

premiun kit

Very good quality and fast shipping, i recommended buy nvx products

This wire is great...

This wire is awesome. .... The installers ran this wire to my 4 channel (Hifonics Brutus X-14 800.4) and monoblock (Hifonics BRD 2000.1D) it handles the current quite nicely. ... doesn't get hot either. .. definitely recommend this. ...

very nice kit

The kit is complete and the power & ground wire are very nice looking and high quality. They are very flexible too and not super stiff like many others. The fuse holder is nice and compact. The speaker wire is excellent too.
Just make sure you add your battery adapter!

Top of the line

This is an amp kit that will bring peace of mind as soon as you open it. This kit is top of the line without question. Look at all of the other brands and even try them (I have had kicker and fosgate kits) then compare to the nvx kit. Without question a must buy for anyone looking to actually get a much better product than what they paid for.

Awesome kit but could've used more speaker connectors

Well the above wasn't really an issue besides me having to stop by the hardware store and getting more crimp connectors. But when paying the amount of money required for this kit, I would've expected more connectors. They only provide you with 4 crimp connectors. Yep, just 4, which accounts for the positive side of the speaker but then you're left in the dark for the negative side of the speaker. Weird. Otherwise they weren't kidding about the thickness of this cable. Does the job wonderfully for the Pioneer GM-D8604. Plenty of speaker wire...more than I needed. All other wires included in the kit were more than enough for my 03 Altima.

NVX SKIT44

Great kit for the price but did not include a sub woofer cable so be sure to buy seperately. Cable was very flexible and easy to work with. Fuse was of good quality. Boots and connectors included. One of the rca cables had a bad connector

Great Speakers at a Great Price

These speaker sound great,very clear and even if you dont have an amp,but adding an amp only makes them sound that much better they love the power.For the price you cant go wrong.

Good quality

They work pretty good, got them powered by a kicker ZX350.4 and sound very clear and clean. Would definitly recommend.

Great Speakers

These speakers are great because the cost is average and the quality is above average. It reproduces music very well and your amp will push them harder because of the impedance.

Grab a set while you can

I'm a serial Infinity speaker installer. Have run Alpine, Kenwood, and a few other brands, but I keep coming back to Infinity for the clarity and overall balance of sound quality and price. I have these run off the head unit for the moment until I can add a four channel amp, and even with 22 watts a channel they are a massive step up from OEM speakers. Lots of different mount options included for the tweeters, but it's on the installer to figure out the best way. I lucked out and these fit directly in the space of my factory tweeters, secured with a dab of hot glue.

Very nice components

These speakers are in the front of my sedan ran off 150w x2 rms amp.
Matched with 5.25" Infinities in rear, and JBL-MS-12SD4 sub getting 1000w rms. Great budget SQ setup in my opinion.
They absolutely sing, and are the best overall mid-highs I've ever gotten from any of my 4 previous setups.
I don't even want to get out of my car when a good song is on loud!
I'm even hearing musical details I usually don't notice on my ipod or home stereo.
Very sharp crisp sound.
For the $$ I doubt you could find better, clean sounding speakers!
Bass is even pretty punchy and smooth, but you will probably want a sub to compliment these.

Quality!

I'm overall very happy with the performance of these speakers.
I installed the 6030cs in my 02 GMC Sierra a couple months ago to replace the stock front speakers. I replaced the 6.5 door woofers, and I installed these tweeters in the mini panels directly behind the mirrors. My head unit (and amp) is a Clarion CZ501. When I was shopping around for this speaker upgrade, my top priority was to get accurate sound reproduction. I can honestly say that the clarity and soundstage from these speakers is beautiful and accurate. The highs are crisp but not harsh. The bass output is punchy, but I wouldn't call it strong. I estimate that the low frequency volume drops off around the 70hz mark, so to get a full sound you'll need a sub. I personally was not expecting to get gobs of low end from these 6.5" speakers, so I don't consider this characteristic a negative.
If you are looking for crisp, accurate sound, then these Infinity's are definitely a good place to start. They are solidly built and fairly easy to install. I subtracted a star from 'Ease of Use' only because it wasn't immediately obvious how to get the crossover unit popped open.

Great amp kit

This is a great amp kit, I got it bundled free with a JBL 5ez amp. Great that they included all wiring for 4 channels. I think I even wired the sub with the extra speaker wire from this kit (essentially got 5ch out of it). Oxygen free copper. Flexible wiring. It's great.

Some small cons:
The ground wire is way too short. Ended up using 0 gauge from my installer since he wanted to ground my amp to the frame of my car. This ground wire wasn't nearly long enough to do that. Ended up giving my ground wire from this kit to him, and using a 0 gauge wire he had. (shaved the 0g wire down so it would fit in my amp terminal).

Also the grommit for the power wire is super super tight, which isnt a bad thing. But we had to actually reverse the power wire to run it through the grommit after drilling through the firewall. The nice looking protection for that section of the cable we weren't able to use. We just used some plastic housing for the cable instead, and the part designed for the hood went into the trunk. It would have been nice to use the power cable as designed. Overall it worked out though.

Still a nice amp kit can't complain since it was bundled free! Speaker wire was great though!

By Samuel on September 4, 2015 Verified purchase

OUTSTANDING!

I have these speakers in the front with the infinity coaxial kappa 62.9i's in the back and theyre running off of the infinity 475a 4 channel amp. the highs get REALLY loud and the sound is powerful and clean and they compliment my 12 inch l7's nicely!

good not great

Very good clean sounding speakers. I originally planed to connect them to my factory head but the didn't sound that good. I added a Rockford amp and they sounded great. I thought the had good range and lots of bass for 6.5" speakers. Sometimes they are too bright and for that reason I rated them a little lower. I wish the crossovers had a -3dB setting.

Great For The Price

These are a great component speaker set for the price.If you set your amplifier up correctly they sound really good.

Very good quality sound

the sound is crystal clear, and the price ROCKS....I fuly recommend these speakers.

Infinity Reference 6030cs

The sound from my aftermarket JVC head unit (50 watts x 4 total output) is very good but these speakers would really benefit from an amp to really get the sound out. The midrange and bass is very good, no distortion, and the tweeters output is adjustable from the crossover unit which is rather large. These speakers fit nicely in my Miata and I highly recommend them for a two way speaker system. The tweeters were very easy to install too. I was not a big fan of the speaker covers, a little too thick for a Miata install, used another speaker cover that was about 1/8" thick.

quality product

I have these mounted in a Yukon XL in the rear doors. They sound beautiful. The performance for the price is excellent. Definitely recommended these speakers.

Great sound for the price

I bought these to replace a pair of alpines. I have an extended cab truck with 4x6 alpines in the back doors, an infinity bass link sub under the seat and a clarion deck and separate amp. These speakers had quite a bit more bass than the alpines did. The sound is also better. I really like these speakers and would highly recommend them for the performance at this price.

First time buying infinity

First time I ever bought anything infinity. These are great sounding but don't expect too much bass. I didnt want bass out of them but if you do you might want to go with another speaker...still good stuff though.

great sound

I would recomend these to anybody, they have great sound quality and can handle bass great, if you are building a system for ur vehicle you cant go wrong this these

Great value

The Infinity 6030cs are one of the best speakers on the market.

Great Sound

Very Crisp and definitely loud. Tweeters will make your ears ring. I also like the many adapters makes it easy to mount these components anywhere. Best value out of any components. Have the older 6020s in my girlfriends car and decided to get these for mine. Replaced my old ks502 components and the sound was incredible.

Great value!

Quality kit for a reasonable price, wires are better quality as compared to others.

By James on April 1, 2020 Verified purchase

good BUT could be better

I bought this speakers by recomendation of a S.E. rep to pair them up with a JL AUDIO JX360.4 amp they sound pretty good but the first pair smoked on me when I was in a car show which was super embarrassing I called sonicelectronix and the exchange was easy now on my 2nd pair and they have a very good SQ but they would be perfect if they can handle more RMS because they are for 90 RMS per side

Beautiful sound

I have a pair of these in my yukon. They are absolutely the clearest speakers i have ever owned. I have them hooked to a four channel pioneer amp and the sound matched with subwoofers is unbelievable. Definitely buy these speakers.

The Real Deal.

IT IS BECOMING HARDER AND HARDER THESE DAYS TO FIND REAL COPPER INSTALLATION KITS AT AN AFFORDABLE PRICE. THEY ARE OUT THERE BUT MOST ARE OVERPRICED, AND SOME DON'T SPECIFY (CCA) or 100% COPPER. THIS KIT IS 100% AND A VALUE. NICE!!!!

Excellent

I currently drive a 2009 Chevy Equinox with an Orion Cobalt CO6004 4 Channel AMP powering Infinity 6.5 Reference REF6030CS Components in front and 6.5 Reference 6032CF in the rear. I decided to buy Infinity's all around with Dynamat in the door and It sounds WAY BETTER.

Both

Both the wiring and capacitor made a huge difference mostly the wiring I liked it so much I went and ordered some 0 gauge wire

Great product!

Very heavy duty wiring but still very flexible and easy to install. Would definitely buy this kit again

Quality wire and RCAs that do what they're supposed to do.

This kit is perfect for any 4-channel amp kit. Very high quality wires and RCAs. I got this free from Sonic with the purchase of my amp. The only negative is that I actually bought (2) 5-channel amps, and had to purchase an extra RCA for each. Not that big a deal, though, as I knew this, and with it being free I didn't have a problem with that.

NVX XKIT44

Love nvx wiring......always up to standards and then some......highly recommended.

Came free with amp

Very good quality, extremely pleased with this amp kit. Came free with my JL amp but I would definitely purchase this amp kit in the future if needed.

Includes everything needed, and comes pre crimped, 100% copper true size.

By Dustin on February 8, 2018 Verified purchase

Good quality

I like these amp kits because the wire is good quality and they give you enough to run all the way back if you have a large SUV. Suburban or excursion

Nice quality and flexibility for tight bends

This cable kit is high quality, appears to be durable and well designed to withstand engine compartment heat. The 100% copper power and ground cables are very flexible making tight bends to keep the installation neat. The length was fine for a Toyota Camry and similar sedan installation in the trunk. I mounted the amp behind the rear seat, cut off about 6 feet of the power cable and coiled excess RCA cables under the back seat. The kit included some plastic wire tires, firewall grommet, heat shrink, terminals and protective sleeves. Highly recommended.

Everything comes with this kit that you would need for a single amp install. Wires appear to be durable. No road noise after hooking everything up. Price is fantastic as well.

nice kit

Very happy with amp kit. Definitely recommend this product. Worked treated

Really good wire

Awesome wire, really liked the extra protection on the power wire. Love the color. Little expensive. Used this for my 08 Evolution GSR, there was plenty of wire to run all 4 channels to each door from the trunk. Only downside is there were not enough wire connectors for the speaker wire, so you will have to buy extra from the hardware store.Very low resistance wire tho so if your looking for quality look no further.

Great Upgrade

I replaced the stock speakers in my GMC 2500 with these and I am very happy with them. They come with a ton of installation options but mine fit the factory position. The x-overs are pretty big but I didn't have an issue stuffing them behind the door panels.

I was worried because some of the reviews indicated that the tweeters were harsh, but I only found this to be true when setting the gains because I was installing a new amp at the same time. Now that they have been in for a couple of weeks I think that they are nicely balanced. The tweeters are installed just above the 6.5 in the door.

The speakers are being powered by an amp - so I don't have any experience running them directly from a deck.

Love Infinity

Great speakers, very natural, a little bright, but well worth the money. Complete kit with lots of extra parts for install. Sonic is great, price is the best, price match is even better!

Nice kit

Pleased with the kit as far as quality and price.. This was my first time buying a kit and rewiring my complete car it had everything I needed with extra to spare..

Nice kit

In the past I've only bought power wire and rca's from knukoncepts. Great stuff. Got a JL XD 400/4 and it came with a free NVX install kit. It's absolutely a great kit, and I would not hesitate to buy NVX kits for another install. Time will tell how well the rca's hold up, but initial impression is high.

Most underated speakers I've known

these speakers are wonderful. If you know how to use your deck and amplifier properly and can tune with clean power, you can't beat these speakers. I have ran them for years and bought a pair for my by newest vehicle. I stand by these fully. better than the kappa's IF you know how to tune and better than a lot of much more expensive speakers. These will easily handle over 100 or more cleans watts of tuned power. Great high end and Mid speaker

Great product

I have had the infinity 6030cs component systems for a few months now and every one that has heard them has had only one thing to say about them they are the clearest sounding speakers they have ever heard. I would highly recommend them to any one that is looking for clarity in thar stereo system.

Good wiring kit.

The guy who did my install does some high end installs and he said they looked to like they were top quality. The shipping was a quick and easy process. Everything I’ve ordered from sonic has arrived quickly usually with 2-3 days

Seems good

I've had other 4 gauge amp kits in the past. This one seems to be accurate in size of wire. And I'm an electrician so I think I know what I'm talking about. Definitely worth the money.

Very nice kit

I got this free with an amp purchase so my expectations were very low. After installing it I wouldn’t hesitate to buy it versus any of the name brand kits. And I was an installation manager for 5 years so I’ve installed lots of pricey kits.

Bad ass kit!

The highest quality wire I ever encountered.
I think it way underrated at 1000 watts. Very nice craftsmanship.

2nd NVX wire kit I've used

I had purchased an NVX XAPK1D for a previous project car and for my Jeep I went with the NVX XKIT44 for my JAD800.4. These kits are the real deal and are very high quality. You get proper wire gauge copper wire that's not 50% insulation like the cheap stuff. It's copper too, not CCA, which I've had with lesser kits. The power and ground wire is super flexible for the size and having the 2 RCA's in a single wire makes it nice a clean to install. I love these NVX kits. This will not be my last.

Good kit for 4 channel amp

Excelente kit, I use it in my jl audio amp rd4/400 And is exactly for my amp.

Very nice wiring kit

I have zero experience until now with NVX. The quality of the wiring kit on every level has made me curious about other NVX products. Plus the kit was actually a two channel kit from the manufacturer but to make it a four channel kit it came with a four channel twisted pair rca , so i now have an extra two channel tested pair ca cable. Great quality and product at a great deal!

Top of the Line AMP KIT, Highly Recommended.

This is the best available kit in town & is my first purchase of NVX kits, I bought both NVX XKIT44 & NVX XAPK0, and guess what! I don't regret on my purchase.
I did a lot of research before I buy these KITS. way to go!
FIVE STARS *
highly recommended to all Basic & Advanced users.

High Quality

If you want quality wiring - get this. You're only going to wire your car once so you might as well spend the money and get good, quality wiring. Well, this is it.

These speakers are 2 thumbs up

I recently brought these speakers and got them installed. I love them alot. I had Kickers kS620 components at first and I wasn't feelin them at all. Please run them off a 4 channel amp. I'm running them off a Kicker ZX350.4 amp and it sounds so damn clear that i don't want to get out of my car. LOL! You won't be disappointed at all. I hope my reveiw helped you to choose because everyone else reviews helped me. Now stop reading and buy these Infinity Reference 6030cs!

Great!

Got this bundled in a deal with my NVX XAD41 amp, and couldn’t be happier.

The wire is ultra flexible and seems over sized, I used NVX brand wire ferrules for a cleaner look and good connection at all points where I would otherwise had a bare wire connection.

I really love the fuse holder, just be sure if you are installing sideways like say on a fender well you mount it with the side screws for the power wire facing where it’s easiest to access. I mounted mine to the fender with liquid nails LN-2000 and two #8 x 1/2 stainless steel screws after double checking it wouldn’t interfere with hood structure or anything else and drilling a pilot hole for the screws.

The RCA and speaker wire is excellent too though I made the mistake of running my RCAs along the door channel next to my new speaker wire runs which are amplified (100w RMS) and so introduced some noise until I moved them, not a lot but I had to turn down my amps gain to avoid some hiss. So if you for some reason can’t run them under the carpet you may want to order some RCA cables with say Mylar shielding.

I really recommend you get the install bay firewall grommets for this size just in case, they are absolute life savers. My best option was to run powerwire though the passenger floorboards firewall and they make me confident that I will have zero water intrusion.

Never received

Couldn't tell you if this is a good kit or not. Have been waiting nearly a month and it appears I will never receive it. I guess no loss since it was "included free" with the amp I bought. Sadly, this was my first and last purchase with Sonic. After paying extra for next day delivery, then receiving the item 5 days after I ordered, we weren't off to a good start. They were supposedly going to send the kit out but it has not shipped, nearly 3 weeks after I was told it would. Received my next day delivery money back about 2 weeks after the order; at least I got that back.

Infinity 6030cs are noticably superior to stock Honda Accord speakers

I would recommend these speakers over the 2007 Honda 4 door VP stock speakers. The 7,000 series Honda 2 door stick shift models have higher quality speakers than the stock in other models but are still inferior to these Infinity Reference speakers. Most Accords have cute little near 1 inch diameter or half dollar sized magnets.
The 07 VP has no dash tweeters. I currently have the tweeters double stick taped to the sail panel forward of the door glass. Driveaccord.com says it is difficult to rewire the tweeters from the crossover through the door opening to the dash mounting area. The dash tweeter grill has no holes for the sound to come out of. I will have to get a replacement pair.
According to my researching on line, only the Accord two door 6 cylinder with stick shift has a crossover. Both this Accord and all others have a second wire pair from the plug at the radio for the tweeter. It was recommended that the wire from the radio go to the Infinity crossover and the crossover be mounted in/just under the arm rest where there is adequate space in both doors.
The two front door speakers which are currently capable of making more bass than these do not have the necessary Mid-range quality and highs to listen to music satisfactorily.
Wanting a quality sound that is necessary at the mid and high end of the audio spectrum to enjoy music, I switched to Infinity so I can actually hear the instruments instead of just hearing the music. Vast improvement for a lifetime audiophile. (67 years OLD)
I could have gotten the better infinity but for a weekend touring car the higher price for short or occasional long drives is not necessary.
The 6.5 inch Infinity reference 6030cs replacements needed aftermarket plastic pop in mounts that can be purchased from the internet for under $6 dollars with free shipping. They are well worth it compared to drilling and grinding the uneven metal and possibly having a contact with the window glass. I did not see a Sonic version of this pop in speaker holder but I did not look for one there.
Be aware that the aftermarket plastic speaker mount that allow a "two second" pop in convenience does not have the correct placement of screw holes to mount these particular Infinity 6.5 inch speakers to the plastic. Using a determined amount of Southern Engineering I placed screws coated in non stick silicone, in the speaker holes, placed the speakers on the plastic pop in mount and applied a fiberglass goo that hardens relatively quickly. I unscrewed the 4 screws and drilled the holes deeper - then installed the supplied foam stick on pads to place on the speaker for air tightness and screwed the speakers on tighter, then popped them in the door frame. The plastic purchased pop in mount had to be roughed up to allow the fibreglass paste to adhere to it.
The stock head unit amplifier has more than enough power to drive these speakers to louder than I can tolerate without distortion from the speakers or the amp. The sound is clean and clear all the way up to the higher frequencies. The sound does not get to be called SHARP until the treble is turned all the way up, IT is more like too loud for the rest of the music, not sharp. This Honda Accord radio head unit is not exactly aftermarket ultra high power amp quality but it is a close second. I do not have to turn up the treble on this stock radio to hear the high frequencies that are hidden from us by the stock speakers.
The bass is not as loud as the stock speakers but the Infinity speakers are new and will loosen up and make more bass as the hours wear them in. When I crank up the bass on this stock radio I can hear the bass nicely but not loudly. I can feel the door vibrate but not hear metal rattling. I might go back in and use some sound deadener later to cancel out the bass canceling sounds from the back of the speaker. I do not have to crank the bass up to hear it with these mid bass speakers. Also because of the Infinity 6 X 9 9633 cf I mounted in the rear (cf means it does not include a grill). I will have to grind down the stock plastic rear grills to fit these speakers or remount them under the back deck like I had the previous temporary speakers. It fits perfectly in the rear speaker opening. The stock speaker grill will need to be ground down to be remounted in their push in slots. The grills have an oval plastic ridge to go down to the metal for a better bass on the OEM Honda 6 X 9 speakers. These Infinity 9633cf speakers have a quarter inch plastic ridge on the top and have to be compensated for.
I am currently enjoying the resounding bass these rear infinity reference 9633cf speakers provide along with the absolutely clear sound they make up to the upper end of the audio range.
I purchased this pair of 6 X 9 9633cf Infinity reference speakers for the back shelf because the Sonic tech ref said they will make bass loud enough with the stock head unit and they are the best bang for the buck for my driving. The holes are there in the back shelf under the pop out speaker grills (you have to grab the 4 pop in tabs in the trunk with needle nose pliers to squeeze the plastic to get it to pop out). The Honda speaker wires are there tucked into the assembly within a few inches of the holes.
A Honda to Infinity speaker wire conversion plug will have to be purchased or special terminals can be purchased at Radio shack to connect to the speakers. Radio Shack sells pn 6403058 which has the two 7/64th female spade push on for the negative speaker terminal and two 3/16 female spade push on terminals for the positive speaker terminal.
Spade terminals will have to be ground down to about 1/3rd the width to plug into the Honda speaker cable socket. This is necessary for both the 9633cf and the 6030cf, 4 of these speaker wire connectors need to be made BUT the time to make them plus the costs of the male and female spade terminals would far offset the lesser cost of purchasing the pre-made units that can be found on line. It cost about $2.50 for a pair of correct sized female spade terminals ($10.00 for 4 pair for all 4 speakers). The Male spade terminals also have to be purchased, and then the males have to be ground to about 1/3rd the width to fit the Honda plug. Then the terminals have to be "SOLDERED-not Crimped" to the wires. Crimping is for a temporary fit because one of the crimps will surely pull off the wire and give you grief sooner or later. It is a great deal less time and grief to purchase these Honda to Infinity conversions. I found out the cable to speaker conversion cables are available after I had made the 4 conversion cables. I did not think to ask the tech or look for them at Sonic but they can be found on the internet.
Everything re-considered, I think if I had purchased the cable converters, the front speaker pop in mounts and made the modifications for the screw holes before hand, I could have mounted all 4 speakers in less than two hours.

Honda has premium sound radios that put out 120 watts RMS that should make you deaf soon. This VP has no specified power rating but it has enough RMS wattage to HURT -- it gets so loud. The Two Ohm rating of the Infinity, has something to do with the loud volume available along with the 93 dB sensitivity rating to make these speakers louder than the stock or other speakers I tried.

These infinity have 2 ohm impedance's. From the small diameter Honda wiring the speaker will probably see 2 Ohms at low and normal volume and not overheat the stock radio amp. They advertise that at higher volumes with the small speaker wire sizes and the bass turned up that the amp sees a 3 to 4 ohm load when the volume is cranked up.
I have read that more powerful aftermarket amps make loud bass and resoundingly better sounding music in other cars with lesser radios, but this "made for Granny / Grandpaw car" has more wattage than I can bear.

Good product great prices

I have not received this set yet, however I have had one before and they are a great value, well made.

Came free with DSP Amp

The wires in the kit are decent quality and are plenty for the amp it came with. However I already had an amp and was adding the new one. This meant I needed larger power cable than the 4awg.

Great stuff

I've never used NVX products before but when this kit arrived I was seriously impressed. Everything is high quality and right up there with other top brands I have used for wires and fuse holders. Lots of strands in the wires as well, they didn't cheap out. Great kit.

Excellent choice stock upgrade

Loud and clear with very little power. I recommend and will add a 4-inch infinity driver to enhance the great sound produced with this component system

These speakers are better then my MB quarts, kickers, kenwoods, sundowns and anything else that ive had. The music is so clean as I listen to everything pretty much.The highs are alittle bright but nothing my EQ didnt fix. I am pushing them with a MB quart 800.4 amp and have a JL 13w7 for my Sub being pushed by a MB quart 1600.1

Awesome speakers

Crystal clear

Great design. Cone and surround material seem thick and durable. Tweeter flush mounts allowed for angling. Crossovers did their job. I have 50 watts rms going to each with no noticeable distortion at high volume. I would highly recommend if you are on a budget.

Great highs

Great speakers if you have a powerful sub to round out the sound. These components put out great highs/treble. Would suggest an amp to feed enough power to get the true benefits of these speakers. Not a lot of bass but that is what the subs are for. Crisp highs are these speakers speciality

you must have an amp for these speakers

i love theses speakers i there in the front with some Polk Audio db651 in the rear sounds great

Great speaker at a great price

I put these speakers in a mustang convertable powered by a kenwood amp and they sound amazing

Huge improvement over stock

I replaced the Bose speakers in my Infiniti G35 with these speakers and the sound difference is incredible. Crisp highs and good bass. Installation hardware came in very handy. Highly recommended.

Infinity components

I've always been a fan of infinity systems but I didn't expect these to be as great as they are! My other vehicle came stock with these and the factory infinity is no match for these! So glad I bought these because it's clear and crisp. Definately a great product for the money. I think the price is remarkable on these!. And these can take a good beating! Give these a try and you be disappointed.

Solid performance for a decent price

Put these in my 09 impreza. The sound is good. It's not audiophile level but it's very good. Don't expect a ton of bass from the 6.5" drivers, they don't do well below 100 htz. If you have a sub and can eq out anything below 100 htz to the door speakers they sound brilliant. My biggest complaint is there is no good way to mount the crossovers. There are screw holes on the bottoms but no way to open them up to mount them. I used 2 sides tape on them inside my door panels but it only lasted maybe 2 days of opening and closing before the tape failed. The tweeters sound great but the +3 db option is not needed. All in all a very good component setup for around $100

can’t wait hook it up to NSP/VSP69

NVX OFC Amp Kits for the win!

Every install I do is using one of these amp kits. My buddies always consider going CCA but I explain to them the benefits of OFC and how NVX makes it affordable but yet very reliable with excellent quality!

By Carson on March 28, 2025 Verified purchase

There kits always available ship fast

Love having a complete to install my amp even includes patch cables. Alot of more expensive one never include the cable and always another purchase to slow down install.

Quality Product and Price

Product comes packaged well and is great quality for the price. The flexibility makes it easy to work with while also being a solid constructed wire kit. Sizing is what it says it is and from what I can tell it is definitely oxygen free copper. Also like the extra protective covering for the installation portion on battery side of the firewall with well crimped ends already available to hook up n go!
