Customer Ratings & Reviews

Excellent car audio power cable

Excellent product. Easy to work with. I bought two sets so I could wire a four channel amp and have extra power wire to do a "big three" wire project under the hood. Highly recommended.

Excellent qaulity.

Excellent product. Great build quality. True to Gauge. NO B.S. specs. The fuse holder is a little tricky.

true

I love this wire it's so much better than my old 4 gauge wire. I put it next to the 4 gauge i bought from a local audio store and the rockford wire was twice as big and way more flexible. Everything in this kit is amazing and it is def worth the price.

amp install kit

very nice kit for the price paid. wire is extremely flexible for gauge. power wire is long enough to go from battery at the front of the engine bay, through the firewall, under dash, under the carpet, down transmission tunnel, under rear seats, into trunk and still have 2 feet to spare. this was done on a 93 chevy beretta, so bigger sedans and suvs may need more wire. i'm very pleased with this kit and would buy again

Rockford Fosgate RFK4I Review

All i can say is wow. Unbelievable power delivery and a crisp clean signal with no distortion or signal loss issues. RF has always been amazing with their products and this kit just adds to that reputation.

Good Wires

Good wires, i like them. They do a good job. They are a lot of money but you get what you paid for, cant go wrong with Rockford products.

Awesome!

like most said the fuse holder was awkward and a little tricky.. but besides that everything is great!

Good Deal!

Good quality at a good price, shipping was good and quick as well.

amazing amp kit

really flexible and bendy and performs much better than anything else

HIGH QUALITY! GREAT BUY!

Great Great Deal! RF's Cables are nice!

Pro:
Really Flexible
Price
HIGH HIGH QUALITY CABLES (i was surprised.)
It looks like licorice. (seriously!) :)
Pre-Attached Fuse Holder and Terminals

Cons:
A different fuseholder would be nice because it just sticks out and was more of a hassle to try and get it in.

awesome

This amp kit is awesome! very thick pure copper wire. runs very clean, power keeps my system knockin. the fuse holders a lil tricky.. overall would recommend 10 times to anyone. Great price as well

Excellent

It is working pretty well. This brand is the best on wires, so No complains

Rockford Fosgate RFK4I

I purchaced these cables a while back to upgrade with more power and work great seller got them to me wery quick and works great. And best price I could find. Lot better than local store. These guys are the real DEALS!!!

Great little unit

The unit is exactly as advertised and makes a great small package sub for any car where space is an issue. It was easy to install and works great - I installed it in a 34 foot motorhome and I could have used a little more power, but it does the trick and I am satisfied.
Pros: ease of installation, size and appearance
Cons: could use a little more power

Rockford Wire

I highly recommend this wire kit! I have it hooked up in my 99 chevy silverado with a kenwood 9105d and JBL GT5s in a sealed box and it's amazing. The wire is defintly full 4 guage. Not copper over aluminum like most cheap brands are. A 4 guage copper over aluminum is like 8 guage true copper. Having proper wire is essential to reaching maximum ability of your amp. If your amp cannot receive the full amount of power then it will overheat and stop working. A good wire kit is a safety investment in your car audio. This is a great kit for the price. Everything you need to hook your amp up. You get what you pay for. Don't get cheap wire and risk your amp, subs, and car battery. Overall great kit and would recommend friends buying!

Great value & fast shipping!

Very good 4 guage wire, pretty much everything what you need for a subwoofer amp wiring... very pliable wire, easy to hide under the carpet. I hook it up to a friend of mine, no sweat :) Sonic has a good deal compare to other retailers. I you've got extra cash, take kicker, the blue one. It is thicker and silver tinted... the one im using right now. :)

quality product

I'm no car audio buff but this works fine for me.

Great Product

Easy to install + high quality components for a basic setup.

RFK4I

this wiring kit was perfect. high quality wire and more than enough length for my 4runner with the amp all the way in the back. i would definitely recommend this kit to anyone

Hey I got RF Amp Kit

OK, got this in today and i ordered it yesterday So Great Shipping and Very Fast, but the wire seems to be under spec and it doesn't stand up to their 4 awg claim, the wire i got at a audio store for cheaper had more copper then this kit, maybe its just this kit, that doesn't stand up to the specs because it is the cheaper one of RF Kits, but for 54$ bucks it is a good deal, the wire is very flexible and very easy to fit in tight places, and i would recommend it to first time installers because, it can make it a lot easier for you, but to other installers look else where, With this kit your just paying for the RF name

top quality

just recieved these a couple days ago and compared it to my other 4 gauge kit from stinger, the difference is insane. this stuff is amazing soooo soft and bendy even better than licorice. none of these other brands that make amp kits come even close to the quality and performance of rockford.

High quality cable!

Excellent product! The positive wire was ready to install right away with no crimping involved. Just had to drill the hole a little larger. The cable is very flexible, durable and is true to it's size rating! Rockford Fosgate did a great job in producing a quality product.

Great product

Never had any problems with this product and if I get a new car I would not settle for less.

great value

I already have 3 of these, they are the best product for the money! Take it from sonic, fast shipping too! I like the maxi fuse holder and all the terminal rings included.

best wire

There is no substitute for this wire this is the quality stuff a competition system needs. I want all fosgate for my wires and RCA's.

Great Quality

I bought these to power an RE SE-X 15 hooked up to a Sundown amp at about 800 RMS. Let me tell you, these cables are GREAT quality. Definitely 4 AWG wire, and plenty of it, enough for me to cut off extra and use it for a "big 3" upgrade. Wires are very flexible. RCA cables are high quality. Im gonna use home stereo speaker wire for my setup so this was perfect. Only flaw is the fuse. Because the fuse-holder uses a MAXI fuse which is very large, it sticks out the side of the fuse holder. Although, this makes for easy inspection of the fuse. Overall a very clean and high quality kit.

Rocford Rocks

The kit comes with everything. The wire is all super flexible, so it is easy to fit in tight places in you're vehicle.

Good quality. Not a complete kit though

This kit only came with ring terminals for one end of the wire. It would be nice if it included a terminal for the other end of the cable!

Good Wire

I got this for 2 12" inch 1200 watt Sony Xplods. But anyways this wire was a charm and haven't had any problem with it.

NICE

Good amp kit. Includes everything thing you need.
Real 4 Guage wire!

Speedy Shipping!

Sonic always ships there products out very quickly. They are my favorite so far, and I have delt with other e-bay stores. This product does exactly what is listed. You won't be disappointed. I know I was'nt.

Awesome

packs alot of power in such a small case. my p1000.1bd did 1308wrms @1ohm . sound quailty is amazing. and doesn't strain your electrical like other amps in its class i dont drop below 13.5 volts on high listenin levels.well built . def would recommend

best thing i ever bought

Very flexible wires easy to put the fuse in only down side that i dont like is how big the fuse holder is and that the fuse sticks out like it does but other than that very great product wouldn't think about buying anything otha kind specially for this price fastest shipping ever

great!

i love this amp kit! would be awesome for the price if it would have speaker wire but i already had some so it is all good. anyways it powers the system so I'm happy

Best

Had off brand, kicker, etc. Nothing lives up to rockfords wires. Measured and it is 4awg power and ground. Not thick insulation and powered my 2 kenwood kac-904d perfectly. 1800 watts was a little much for 4awg but anything under 1500 would work great.

Greatest For The Price

I purchased this product from B*** B** and i paid twice as much. I wish i would have purchased it at Sonic Electronix for half the price!!!!

Overall, it is a great kit. came with everything but speaker wire, but it was thick enough and it powers my 1000 watt RMS amp.

great amp!

great amp! my birth sheet read 1399wrms at 1 ohm. Running some Boston G5 12s with a custom ported box in the making. With certain songs it makes you see double going down the road.

I liked it

I would recommend this product to anyone installing an amp. The power and ground wires are really nice quality wires. The whole kit is just a nice put together kit. Love it

RF has the best amps

I've had one of these pushing two RF power T1D412's for over 4 years now and they're still beating down, thankful I put dynamat all around in my truck. Now upgrading to a RF T2500.1bdcp, two T2D412's and a RFC10HB cap along with even more power upgrades.

Better than expected! Birht sheet well over 1000 watts!

Use to have this amp hooked up to an RE Audio sub and wow did this thing deliver the power!!! Birth sheet rated this amp at over 1100 watts rms at 1-ohm! Fantastic value for money, rockford only sells the best!

great amp

Let me tell you, this amp sounds realy clear and clean. its realy powerful it rocks my 2 15's alpine realy good. this is a great amp i could say that because i owned a lot of amps in the past. I don't think i would buy another amp. rockford rocks

top quality

this amp is as good as it gets without really having to upgrade all of your electrical system.
i have mine with original battery and alternator.
all i added was 4 gauge wire and a capacitor
lights dont even dim with my 2 12"s

Great Value!

I wanted to install my own sound system in my Dodge Dakota and wanted to do it right. I bought this kit based on other reviews and because of the quality Rockford is known for. After getting this kit and using it, I can say it's all very high quality. I have been using my system now for over 6 months, no issues!

Amp Wiring Kit

This kit did exactly what I needed it to so I could hook up my amp. There is plenty of cable to run from the battery all the way to the back of the car and all the needed accessories are included. I would highly recommend this kit.

Great Kit. Good Value

Installed in a 2007 Chevy Trailblazer SS and a Pontiac Torrent. All wiring was long enough to reach the rear tray nicely and the quality was great. Everything I needed to get my MTX amps and Alpine subs bumping again was in the kit. Did need more zip ties but those are cheap. Sounds great and better than the low grade CCA autopart store kits for a similar price. If you are debating price versus quality this is a clear winner in both categories. Signal RCA's didn't look too robust but have not had any issues.

Great Wire Kit

The quality of Rockford Fosgate is undeniable. These wires deliver the power I need with no problem at all. System has a crisp clear sound and I am very satisfied.

Works good

No problems with it, works perfect still after about 5 months.

rockford fosgate punch p1000-bd

I bought a pair of these amps to run 2 audiobahn ultra excursion 15's in my 95' Lincoln town car in a slot port box and I have only hooked up 1 amp. It's 1350 rms and 4051 watts peak. Barely uses any power from the car still have stock alternator and it does dim lights. I am sold on this amp won't ever sell it

Good Amp Kit

Everything was good except no speaker wires.
High quality wiring and insulation.
Highly recommended.

Rockforf Fosgate 4 Gauge Kit

This is a nice kit... True 4 gauge... really easy to work with.... really flexible... all in all a great product...

GREAT WIRING KIT

This kit works great. I used it to power my alpine 1000 watt amp. Easy to install. Don't waste your cash on cheap kits from w*****.

great quality!

These wires are awesome...The quality is great and it really utilizes all of your amp's true potential power.

RF 4 gauge

This product is great. Just got it in the mail. One of the things is that the Rockford wiring is very nicely insulated, most people wont see that. Its very flexible. They give you a honest product with 1600+ strands in that copper wiring.

Great

Got this item as a replacement for my broken p600 from rockford fosgate themselves. Drives my 12'' Pioneer Premieres(2ohm) like I've never heard before Rated at 935rms at 2ohms well over 1400 at 1ohm. Wouldn't recommend any other amp if you need the power. This thing is loud!

Hmmm...not ENOUGH

So i got this kit because its RF and 4 AWG, sounds good to me, but it didn't have all the terminals necessary for complete amp installation. Overall its an alright kit, but i would recommend spending a little more on a higher end wiring kit.

Its wire hehe

Well nice and easy to install, downfall of it all is the price and an ok fuse holder.

You won't regret this purchase

I bought this amp a little while ago and all I can say is wow this amp is leaps and bounds better than my last amp. I'm running 2 alpine type r's and I'm rattling my house when I pull up.

GREAT AMP

I bought this amp and took it to my friends house to test it out. When my friend hooked it up it sparked and i got scared the the amp was blown or something. Comes out that he hooked it up wrong but luckily nothing happened to the amp. Runs like a beast. So I would recommend. Pushing 2 10" L7's.

super bass!!!

I own these babies and they are ridiculously loud. I put them in and took it to my local audio shop I use to work at, and everyone thought I had 12's. When they saw I only had 2 10's, they were super shocked. I got a Hifonics BRZ 1700.1 powering these babies. A true 1700W RMS amp at 1 ohm and I'm smashing the streets. If you have the amp I have, you will need a secondary battery and a high output alternator with the big 3 wire. I definitely recommend these. They hit the high and lows super good, especially when I played Ambition by Wale. When that bass drops, you can feel it in your throat, and it feel like its choking you. Rockford is doing soo good right now.

Great wire

I would recommend this product it is very nice high-quality wire.

Punch with a PUNCH!!

As usual, Rockford does it again. Over the years Rockford has put out some great products & some that were not so great. The punch p3's are simply awesome! I think these subs are one of Fosgate's greatest achievements. I would & do recommend these subs to anyone who is looking for some ground shaking, heart pounding bass to add to their system.

great buy!

Great price, great sound and easy plug and play. Would recommend anyday!

The perfect kit

I will always buy RF wiring kits. They never disappoint and the wire is more like 3 gauge!

Rockford Fosgate RFK4I 2-Channel/Mono Amp Wiring Kit

Great amp kit high quality It's Rockford Fosgate! Best of the best.

Great value

Great product for the money. Quality amp kit. Everything I needed for my setup. Would buy again.

amp got my car trunk on blam

Bought the punch p1000-1bd from Sonic, as always fast shipping from Sonic, amp came in a perfect condition. Just the way i like to receive my items in a perfect condition including the box that the amp came in. As for the amp, the amp is one hell of a beast, the amp that i received was rated at over 1300 rms @ 1 ohm which was perfect for my car audio application (thanks to Lucas L & Wes M ), this amp got my car trunk on blam, got my woofers powering like crazy, i just hope that my rear windshield survives the abuse its getting from this amp, no kidding, lol.

very good amp,rockford is the best

I've used those cheap 4000 watts amps their huge, this amp hits way harder, and is way cleaner bass, this amp is very strong, and will push any sub hard..but I should of spent 20 more dollars and got the Rockford Fosgate Power 1000 they accept 0 gauge,this doesn't..

YOU WILL NOT BE DISSAPOINTED!

Up to now I have had 2 10" Pioneers with an 800 watt max amp. Yesterday I bought this amp and today I ran a 4 gauge cable to the battery and did all the installations and hooked it up to my friends 2 12" subs and man does this amp drive those things!!!

We listened to 1 song by lil john and came out of there with a headache, the volume was only 1/4th of the way up, and the gain was at 1 and punch eq low also.
This amp for this price is a steal!
I recommend this to everyone, it has much more watts than you are ever going to need!! In your whole life! Im telling you I have these and I dont think I will ever upgrade again, at least not the amp...

My review 5/5 If you buy it from the Rockford website it costs like 600 but for 400 bucks you cannot find a better amp anywhere.

good product

this amp very powerful and clean, i am running it with 2 pioneer 3000 watts dual 4 subs and its loud, sounds great i love it, good amp to buy, i love this site.

Rockford has done it again!

I have been selling Rockford Fosgate Amps for the last 4 years and this is the first model that has impressed me near what the old ones have. This amp is a BD so it is very efficiant, my birth certificate that came with with it rated my amp to run 1197 watts rmsx1@1 ohm. Have not had a single complaint or concern with this amp. Highly recommended. Only downfall is it no longer comes with the bass knob like the older models.

Pricing is great

Best kit out there for people not wanting to waste a lot of money. Plus shipping was next day free. Overall great quality product.

Awesome buy!

Did what it was made to do!
Only downside is the fuse-holder, I have mine zip tied in the holder.

Solid, Great Amp

Delivered fast. Amp works great. Powers my two 12" subs with ease. Just remember that this is a single channel amp.

Great Amp Choice

This amp is excellent! Dont hesitate to buy it over the more expensive ones! You will not be disappointed! I have mine running a SVC 12" MTX 9500 and the thing pumps like nothing Ive heard around this area and Ive got an 07 Accord Sedan,.. if your debating between this amp and another more pricey one! Definitely look no further!

upgrade your charging system!

i have this amp installed in my 92 camaro pushing 2 alpine type r 12's in a sealed "enclosure" built down into the vehicles trunk pocket... it brings the hurt.

outstanding performance

I run mine with a T-500-1 bdcp and they beat my nissan versa in the ground. These subs are top-of-the-line and will last a long time, if you know what you are doing. If you like these subs, get them. I am sure you will be happy with them. No regrets here.

Expected more

I have these subs and i am running a massive audio 2400 watt n3 and a rockfork 10 farad cap to it. i thought these subs would be louder because of the rms raiting. I blew these subs out in a month of use also. I would recommend getting a t2 instead of these.

Amazing power

Have this amp powering 2 15" rockford t1's pushes them with ease. It's a small design with very clean power. Has a very cool design for nice clean set up without showing wires everywhere. I definitely recommend this amp to any one who wants a quality amp.

P10001bd

I would recommend it. this amp lives up to its name. most birth sheets for this amp are 1100+ rms. Mine was rated almost 1300rms (1278 rms). Honestly, this amp is simple, not much in the back that complicated. It powers woofers like crazy but we warned it could blow them too if not properly tuned.

Bangin

This amp is true to the ratings!!! My birth certificate read 1403 rms at 1 ohm. I got two P3's hooked up to this bad baby and they hit hard. I would recommend this to anybody. Oh yeah it never overheats either. I had it cranking all the way from Detroit to Flint and it kept going and going just like the energizer bunny!!!

Good Amp

I have this amp pushing my two 12" Rockford Fosgate P3s. My friend has the R.F. P500 pushing the same subs and mine is clearly louder. Only downfall is no remote included. I recommend this product.

Sweet Box

Bought this box to put in my car b/c I did not feel like home making one
and it was well worth it....
have it hooked up to the Rockford P1000X1BD
and OMG it thumps hard !!!!!!
it keeps up with my neighbors 2 12 inch box he has
the only difference between this one and his was
this one had no distortion at max volume ,,,no clipping on the amp at all
this box just pounded away
works great on all kinds of music,,,,,
but works the best on pop, techno, country, classic rock

The Best out there !

These speakers sound great and the enclosure looks great,this is a super buy.RF rocks !!!

Best subs I've ever owned!

I love these subs! And the box looks nice, too. They bump much harder than the Kickers I've had in the past. I have them powered by a Rockford Fosgate 1200 watt amp, and it's the perfect match! Sounds great!
