Well worth the money, go hard or go home!!! Only mess with the best

Awesome Kit!

Came With Everything described in kit. If Your looking to push that power to your system, This kit will do it! Worth Every Penny!!

NVX XKIT02

This is a nice wiring kit no doubt about it. Very sturdy and flexible, easy to work with. It is definitely true 1/0 cable and seems to be pushing the Hifonics BRX2000 amp I have with more than enough power. Rca's are also pretty nice and seem to be working as stated (no feedback or humming). I also like the fact that the battery side of the power cable is pre-sleeved and has the ring terminal already installed for you with heat shrinks as well. Same on the ground cable. Over all its a nice kit, might be a little pricey compared to other kits, but you pay for quality. Well worth the money in my opinion.

Fine Wire

Wires seem accurate. They transfer plenty power but I do have to upgrade battery to turn amp up more only running it at .25(1/4) and even then my lights dim front to back.

Nothing but the best!

A little heavy but my stereo system sounds great! Would buy this again!

Good kit

Comes with everything except rca cables, includes some terminals and boots, look for the bundle and save a lot

premiun

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

Awesome

I got this kit to wire a boss 2600 watt amp. The wires were huge there was no way I could run it to my amp. The quality was so great that instead of returning it I used it to upgrade my battery cables and my chassis ground. I only wish it came with more ground wire as I need a few more feet to finish my chassis ground upgrade.

great kit

nice kit good quality but says in description 300a fuse but only comes with 150a fuse

----

NOTE FROM SONIC ELECTRONIX:
300A Fuse sent to customer due to typo on our behalf. We also updated the description.

Super Value

I've owned wiring kits before but this NVX kit put in great work, it has oxygen free copper that is flexable and put clean power to your amp. You will not be dissapointed this is a good value product.

RF is great but.......

I have owned fosgate for years and was pushing their amps like no tommorow. I recently had one of the 2500dbcp and are great. There is an amp out there that it flat cheaper and better, its called Sundown audio. Sonic has to start carrying their stuff,ive been blind by all major brands. Sundown are beasts just like fosgate. There subs are versitile and amps go down to .025ohms!! Ive played around with the saz2500 by sundown and the 2500RF and are both great but obviously ones meant for competition. Plus Sundown is cleaner and easier to dial in, just go see for yourself Sonicelectronix and see if ya'll cant start selling the Sundown line too???

Real power!

I own 2 of these monster amps!! They both are 3400 rms @ 1 ohm each!! I have them each pushing an 18' FI Audio SP4 in 14 cubed boxed tunned to 35hrtz. These things need power though. I have a 320amp mechman alternator, 3 kinetick 2500's and monster 0 gauge wire. All I can say is it is stupid loud! It shakes buildings, windows and the cars around me get a free system in their car while I'm driving by haha if you have the money then buy this thing!! Truly a clean and powerful amp. Don't think twice about!

t2500

This amp is beasty I recommend it to anyone who wants to put the best u can in your car. quality stuff man! I have a t2500 runnin 2 t2 12s and its still to much power so coming soon is a 3 sub enclosure custom fit for a yukon well see how that wrks out kuz the 2 already rattle my truck

Solid craftsmanship, worth the money!

These amps are not cheap because they aren't put together cheaply! Very underrated, the birth sheet I got claimed it reached 3548 watts! This is one solid amp, the speaker output and voltage sweep meters are great and are mesmerizing! If you have to wait and save your money to get one, do it!

Awsome amp

I bought this amp and i needed a good amp to push my old 15" orion hcca and it did that just fine now I'm pushing a 15 inch t2 and that amp is a beast had a JL audio 1000.1 black top amp and a t1500.1 Rockford amp and this amp puts them in their graves for sure i would recommend this amp to people just like me who want clean bass and extremely loud subs i have this in my 1989 gmc sierra 4x4.

BEAST

Got this hooked up to one solo x 12. That's all you need and trust me you will love it. Hits so hard I feel like my windows are going to break.

Holy...

This amp is disgusting. I love it. I had 2 Alpine Type x10's on it with gain way down. Blew them out rather quickly. I seriously recommend this thing if you have the equipment to handle it. You have to beef up everything. I bough a 270 amp alt from American Electric, an XS Power S3400. I ran all 1/0 wiring everywhere. I also picked up a Rockford Fosgate 10 Farad cap. My light still dimmed so much they almost went out. You have to run a secondary battery period. Like i said if you have the equipment to run this thing then get it.

Powerful amp

I have this amp pushing 2 L7 15s in my escalade 2500 rms of clean power and when I first heard this thing the whole building was shaking at the car audio shop. The most powerful and clean amp I have ever owned. I bang only gospel rap so I am still keeping it holy for Jesus. You will not go wrong getting this amp. I didnt buy from Sonic Electronix but I have read good things about this place. My birtsheet said 3248 at 1 ohm so you know its a beast.

BEAST MODE AMP

This amp is by far the best amp in the market my birth sheet says 3540 rms at 1 ohm that's enough power for basically any application cant wait to hook up my 3 kicker L7 15 dual 2 ohm wired them to series / parallel to get the 1 ohm load i will be at peace lol

Awesome amplifier

I bought this amplifier because I was looking for something with high power. I never would have expected the results I got. I ran this amplifier with forgetting to hook up the back battery. This amplifier play strong all through the power of the battery and seemed to put the power out the whole time. I would recommend this amplifier to anyone looking to get massive power to their subwoofers.

Nvx O- Guage Amp kit

NVX Amp kit is Pure Quality at first I was thinking it was a little pricey
compared to other kits I found online. I went ahead and ordered because it seemed to be best in quality, and sure enough. Awesome kit
I liked it so much I ordered another to rewire my other truck.
Worth every penny and then some!!

By Roysters74 on April 29, 2020 Verified purchase

Great kit at a great price!

This kit looks great! The wire is definitely true gauge, it measures at 16mm for the housing, and just over 12mm for the wire itself. Having the ends pre-terminated and shrunk guarantees a solid connection without having to buy special tools. The power wire is partially covered in braided sleeving which helps protect it in the engine bay. Fuse block is nice and came with a 150 AMP ANL ( not mini ANL as stated in the description) but no complaints here because that's better considering the amount of current traveling through it. Speaker wire is true 12 gauge as well. Overall excellent kit for the money definitely would recommend!

By Mike on October 29, 2015 Verified purchase

Tons of power

I have the 2009 model, but if 2010 is anything like the 2009, you will be happy.

Having same output on a 2 Ohm load opens up way more possibilities.

My 2009 came with just under 3200RMS and is running 2 Alpine 12" Type Xs beautifully. I'm a bit disappointed SE discontinued selling the 2009 model tho, I was going to purchase 1 more later on and get 2 12" SSA XCONs and run each 2 Ohms off each amp.

Great wire kit!!

This is one of if not the best value wire kits made. All of the NIX wire kits have the best quality wires and terminals. I have recommended this brand to everyone I know.

Great Kit!

Great kit! Highly recommend. Very high quality and true spec!

By Raul on April 19, 2018 Verified purchase

Best wiring kit!

Probably the best kit I've ever bought. Nice "true to spec" heavy cables but are very flexible and easy to work with. Comes with absolutely everything needed for a clean install. Only negative is the cover for the fuse holder can pop off easily. That is very minor and I would highly recommend this kit especially paired with the NVX JAD 1200.1 amp.

By Justin on May 31, 2016 Verified purchase

Great wire would use for all my set ups

Good insulation rubber is soft and peels back fairly easy def use again

Beast amp!!

This amp is just ridiculous with the output power,birthsheet rating at 3,532 watts output. Well worth the $ for this amp,just make sure you have the electrical to power it. It needs some power for sure.

Awesome product!

these wires are simply amazing.. make damn sure you buy quality wire cutters!! i broke two wire cutters trying to cut it. lol

By tom on May 23, 2016 Verified purchase

Awesome amp

Great amp pushes true Beast wattage, had mines rated at 3126 @ 1ohm and 3056 @ 2ohms.
That fact Alones shows how great Rockford products are.
Would recommend this for any sound system, have mines running one 18'DC level 5 and it sounds AWESOME!!
Both L.E.D monitor above helps great when I needed to check voltage and clipping.
Sonic Electronix has the best prices and shipping is quick, less then 2 weeks to get to me in Hawaii, with processing being done in a day off a 2500$ sale I'm impressed with the services.
Only con I would have if they decided not to sell this product again cause I'm looking to add more too my system!!

Great buy

I bought these wire a little skeptical about them at first but after I got them I was relieved there everything I expected.

By Camilo on May 14, 2020 Verified purchase

Top of the line

This is some serious stuff! 100% OFC is worth the extra money.. Excellent quality wire,super flexible for 0gauge. ring terminals already attached with heat shrink and protective loom .beefy speaker wire and decent RCAs..

great value

i love this amp got it pushing 4 15
inch type r in a yukon unbeleivable pressure wow also recomend a high powered alternator and extra battery cant go wrong with this amp stupid power

One of the good wire kits

Great wire kit. Great bang for your buck. A lot of extras definitely make it worth the money.

By FaceDa6 on May 23, 2020 Verified purchase

you want real power

I have two T-2500bdCP amps in a 99 Cadillac Deville running 2 HCCA 15.4 subs the monster subs need monster power and the amps give the hcca's all they eat and trust me the subs are power hungry good job Rockford Fosgate for this power house and thanks sonic for your great price you have made this bass head very happy!!!!!!

Excellent kit

Kit included everything needed. The quality is excellent. Couldn’t ask for better for the price

By Brian on October 31, 2020 Verified purchase

These subs POUND!

I had 2 15" Massive Audio GTX154 and switched to 2 of these 12" SUMMOXLs and they hit so freaking hard! My whole Jeep Patriot is flexing, almost afraid that the back window is going to blow out. Have them running on a 2000 watt Hifonics Brutus amp wired to 1 ohm in a ported Atrend SPL Bass box. You will not be disappointed in these subs.

Rockford Fosgate Power T2500-1bdCP

What a lot of people don’t understand about these amps is when your impedance rises this amp want loose as near as much power as normal unregulated amps and why it will be louder in the real world where it matters. I highly recommend anything Rockford and the only real cons is there prices but ha you get what you pay for and if you want one of the best this is it.

Great Product

I have to say NVX makes a great product. I would highly recommend trying this product, I've had no problems and its flexibility and high quality are a few of the reasons to purchase this product and see for yourself.

Great Kit

So glad i ordered this kit. If you are going to be pushing above 1000 watts this kit is perfect, this was my first NVX purchase and I have since ordered 4 more. NVX doesn't cut corners and all of their products are top quality.

By STICKY G on January 22, 2016 Verified purchase

Great buy

Comes with everything you need. Easy to install with no problems. Great easy to bend wire even 0/1 wire flexed easily.

Very very very pleased

These subs have a physical and auditorial presence that far exceeds any sub I have ever owned. I play them at volume 10 because everything in the car starts shaking at that point and they look good. Quality subs

By 8terry13 on February 23, 2018 Verified purchase

Summo Thunder

I bought two of these and have been using them for the last couple of days. I'm running them on 800 watts rms wired at 4ohms and these subs are loud.

By Canetrane on February 23, 2018 Verified purchase

ridiculous

This amp is ridiculous puts out a ton of power & draws a lot of power also i have to get a beefed up alternator & a yellow cap battery

WOW

amp replaced a crescendo bc3500 i must say i am happy i did that my subs sound cleaner, hit harder and get lower just by swapping amps! the BC3500 was a tank tho, lots of power and clean sound but you just cant beat a rockford bdcp --- 3k and under rockford makes the best amps hands down. this is coming from owning sundown, soundqubed, crossfire etc thats all great stuff but again if your running under 3k just get the 2500bdcp. everything about this amp is clean. installation is kind of a pain but just take your time.

Awesome amp!

Awesome amp best I've ever bought Sonic Electronix is my go to for my vehicles sound systems and my wife's vehicles.

By Randy on August 10, 2023 Verified purchase

Perfect

Got this bundled in a deal with my NVX XAD14 amp, 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.

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.

By Frank R. on July 7, 2023 Verified purchase

Seems good quality

Seems good quality and flexible. The reason I gave it 4 stars under features is that it comes with a 12 awg speaker wire. I used 10 awg.

By Kyriakos on February 22, 2023 Verified purchase

The real deal

The amp kit didn't feel cheap & lightweight. True to spec.

By Gerard on March 16, 2022 Verified purchase

Awesome!!!

Whewww where do I start I have four of these running them on a pure audio 3K and all I'mma say is you get what you pay for once you experience these subs it ain't no going back to anything else ???????????? wish I can add more stars

Great product

I want to start by saying that the shipping was faster then I expected it to be and the product is “AWESOME” I am barley breaking them in and then sound amazing..... I was I little skeptical bout massive audio because I never use them but I am now a fan and want to see wat else’s there products are capable of.... I had 2 12 NVX that hit really good and hard but it was time for some new and louder and I found it.....I would definitely recommend this sub to anyone and I have not yet had any cons to say just over all a great subwoofer. Just want to thank sonic electronix for always having the best deals and fast shipping...

Rockford Fosgate T2500-1bdCP

I have owned many Rockford Fosgate amplifiers through the years. I have only purchased amps from their "Power" series since the mid 1980s. I also have a few of their new Compact Power amps like the T1000x5ad and the several of their T750X1bd mono amps.

However, when it comes to massive, over the top, TOO MUCH IS JUST RIGHT kind of amplifiers, the Rockford Fosgate - Power T2500-1bdCP is ABSOLUTLEY INSANE!!!! This amp come with specs needed for recommended alternator amperage output, and it's no joke. This is one of the most incredible amps that I have ever owned. Many thanks to Sonic Electronic for keeping me informed and up to date on shipping and availability for this amplifier purchase. I give the amplifier 5 out of 5 stars.

Overall a great amp indeed!!

Amp wiring kit

Just as good as some of the big name brands. I’ve had it for a few years and it’s holding up very well. I’ll buy it again. HEAVY DUTY.

Great product very flexible and very good wiring kit

By Eustace on March 23, 2025 Verified purchase

Amazing product

I'm happy I pulled the trigger on this one. I find that the power it delivers at all impedance levels but especially at high ones is what makes it a fantastic buy. I also like the cooling design with massive heatsinks and all passive for low noise (no fan). The indicators were quite nice to have, it appears my processor averages voltage whereas the RF amp shows more granular voltage dips. Only two minor things stop it from being perfect, a little turn on thump (should be avoidable with a relay) and the subsonic is a bit inflexible at 25hz with shallow slope (but I use the one in my processor). So overall the small issues can be avoided. I will definitely consider it for other applications in the future as well.

By George on January 19, 2025 Verified purchase

Best bang for your buck

I did a lot of research prior to buying this kit. I also bought 20 ft extra of NVX 1/0 to do the big 3 upgrade. Considered GP or one of the other well known competition audio businesses but couldn’t pass this up for the price during Black Friday. The quality of the wire is great and even the fuse in the amp kit seems like decent quality. Having no issues sending power to my amp (Kicker CXA1200.1) and get very little gauge dimming on a stock battery and alternator. I know when I upgrade my system to something bigger it’ll handle it no problem too.

Fosgate T2500

Love the brand and the amp shipped out fast and received it in jus a couple days, only problem is the box said what was in the box and it was just left on the front porch for such a pricey item it should need to be signed for but all in all great product and great service.

High quality wiring kit!

I received this kit for free, it was a promotion with the purchase of an Audiocontrol LC-5.1300 amplifier. It is my first time dealing with NVX power wire. The kit is of very high quality, from the power and speaker wiring itself, to the pre-installed nylon mesh, power connections, and the fuse holder. This kit makes wiring easy and straight forward. It’s easy to see that there was some good effort placed on the placement of all the pieces along the wire run. Another positive is that the wire fits easily into 0-gauge connections. In the past, it could be very frustrating dealing with wire that was bigger than spec. I get the whole “you’re getting more”, but I’d rather have a wire that meets the spec or maybe a little over, but not so much that it takes away from easily fitting into the connections. From this point on, I’m sold on NVX power wire. I will be looking at them for sure for my future builds.

Side note. I did not use the RCA’s, so I can’t comment on them, but seeing the quality of the kit itself, I wouldn’t be worried about using them.

Best amp EVER!

The T2500 is iconically the most legendary amp ever. Absolute beauty to look at and a powerhouse in the vehicle! Definitely an amplifier that can run any sub just about as it puts out way more than its RMS wattage!

By Carson on March 29, 2025 Verified purchase

Amazing Amp Kit!

This OFC 0 gauge kit was used in my dad’s Buick wagon for his 4500 watt amp and it smacks with his 4 10” NVX v3 subs. Even he tells me he’s never seen wire so perfectly priced without hurting the bank!
