Customer Ratings & Reviews

Quality Product

Works very well with my Rockford Fosgate sub system in my car.

good deal!

Pretty decent value for the price. Worked out great, thanks.

Usable

The wiring has done me right so far but the only thing I don't like is the speaker wires. You have to carefully split it so the wire doesn't show. Other than that minor thing everything was great and a great value!

price is right

the price is right for this setup. the ground wire and the power wire are to big for my amp but i made them fit. better to have to much than not enough so if i upgrade to a larger amp it will be fine.

Accessories for product

Just what I needed and made installation so much easier. Thanks

awesome products

I run 2 12inch audiobahn exursions on this amp and it pushes them very well. The size is perfect not to big and fits right unerneath the seat or small space. The best part is it stays pretty cool even after running most the day.

good wires

I like the wire kit I got with my amp it seems to be holding up goo it handles the power of the amp I got but I would of gave it 5 stars all the way around but I wold of like the ground at less 2 more feet for good use but over all its a nice kit

Good stuff

Great product last a long time good value for the money.

Cable

Good product fast shipping awsome seller... keep up the good work.....

Perfect kit

Comes with everything you need. Works good with my 800w system

Good deal.

I purchased this for the value. Everything you need for a simple single amp install in one package. Good quality with good value, thanks.

Great Value Kit!

I would highly recommend this package to anyone looking to do a cheap install, i have friends who got these before and its nice, simple and cheap!
Never had any issues, great value!

By Craig on October 15, 2016 Verified purchase

Ok. not the best kit.

The eyelet connectors are flimsy and the speaker wire is hard to separate. When it does it exposes some of the copper. Otherwise the kit is ok.

By Lloyd on December 10, 2015 Verified purchase

Ok value

Good product , but not enough speaker wire to wire two front door speakers in a scion xb. I guess it would have been enough if I had run one of them with the power wire instead of running on the other side of car, but everybody knows that's a bad idea due to engine noise. You would think they would take that into consideration. Also not a big fan of the square and round speaker wire very hard to separate and strip without exposing bare wire.

Great value

Does the job does what it needs to do. It was packaged nicely.

You get what you pay for....

Bought this kit for my 650 watt rms amp. Not true awg 4 guage, but close.jacket is pretty thick.all wires flexible. Reached under the back seat of my 2008 silverado crew cab. But not a whole lot of slack if your going to a trunk. Fuse is ok... ive seen better and worse. Bottom line, if your on a budget and running 800 rms or under, this will work fine.

Great wire

Ran wire though firewall with ease m, and is powering my 1500 RMS amp no problem.

NVX marine amp NVX VAD8402

after considerable research, I ordered this amp NVX VAD8402 to drive 4x Wetsounds Rev8 tower speakers. Got it all connected and sounds amazing!!!

Great value

Bought it to try out but is a really good power rating and not cheaply made for price and is really flexable

By Paul on October 17, 2017 Verified purchase

Great Amp

I’m running this amp with 4- JL Audio 8.8” Coax speakers in my boat. Amp is running 2ohms channel speakers are seeing around 200w each. I’m not running the filter on the amp just adjusting at the Simrad head unit. Super clean sound. I’m adding 4 JL 7.7s in the rear and I’ll power those with another 2Ch NVX Amp. Also, I play my system at the sandbar for hours with no issues. I can even start my boat on the same battery after hours of playtime. I will absolutely buy another ????

By Richards on June 16, 2021 Verified purchase

Great price

This kit has a great price. Everything in the kit seems to be great quality much better than expected for the price. Very fast shipping. Everything you need to do a amp and sub install. Will be ordering more.

Perfect for a fishing boat!

Threw this in my fishing boat to power just to have some tunes n now im disgnated dj for the fishing cove!

Perfect!

Was surprised with the quality of the copper and actual size of the wires compared to other cheap brands like Schoshe. Worth every penny.

Great amp for the money

I was looking for an affordable bass amp and this one definitely did not disappoint! It has great power and makes my Kicker 12s sound better than ever before. The small form factor is a bonus. So much power from a small amp! I will definitely be looking into more NVX products in the future

Good kit

Basic kit to get you going. Speaker wire needs to be just a little better.

This kit had everything I needed to complete my installation. Great product.

By Tony on December 15, 2017 Verified purchase

Great wires!!

After reading reviews and most importantly watching the video Sonic posted with this product, I decided to give it a shot for my Cerwin Vega VPAS-12. The wires are exactly as described, true 4 gauge, not all insulation like the other brands. The fuse block is solid and easy to set up. I was worried it may not fit the VPAS connectors since they mention 8 gauge, but it works and it is holding in no problem.

The only thing I did change was the actual battery and ground terminals, they seemed weak, so i chose something stronger and all is well.

Thanks again Sonic!!

By Fabio on March 16, 2020 Verified purchase

Great little amp

I had 2 Rockford Fosgate P3 12s in my f150 on a Rockford 800watt amp and it lasted about 2 years. I replaced it with this amp and it's outlast my Rockford and is still going strong in a friend car. I would purchase it again for sure.

By Chris on May 10, 2022 Verified purchase

Decent Product

Works very well, wish it included longer zip ties but overall a good kit that has true 4 gauge wire!

By Lachlan on April 8, 2020 Verified purchase

Great amp

This is my second NVX amp (also have the JAD800.4). Love both of them. Small but powerful

By Anonymous on September 21, 2019 Verified purchase

Very well made products

For the price, this installation kit is great. You can spend 4 times the amount for killer connections but if budget and functionality are key, this is the best.

By JAMES on June 9, 2020 Verified purchase

Great Value

I installed this amp on my wake boat to power (2) 9" horn-loaded kicker tower speakers, excellent sound quality, and clarity. I would recommend this amp to anyone looking for a good alternative to some of the higher-end marine amplifiers out there.

By randall on May 13, 2021 Verified purchase

Great quality wire, plenty enough for the job. Works great and made my install a breeze.

Great product, great price does excalty what I needed it to do... would recommend for anyone who needs to get there AMP hooked up properly.... comes with everything you need to do the job right

By Edward on February 18, 2020 Verified purchase

Tons of clean power!

This is the second NVX 8402 that I bought. I love the fact that it has an integrated fan to keep it cool. There is virtually no sound, like some amps, on start up. When the volume is low and you set the gain properly, once again, no background noise or his. Super clean power!! I have this powering an Infinity KAPPA 90-CSX 6x9 component set with the added KAPPA 20MX mid in a '05 Ram quad cab. When I play HIRES USB files, I swear, I feel like I'm in the studio or concert where the recording was made. This replaced a Rockford Prime 500 watt amp which sounded good but didn't really feed my Infinity speakers like they needed. So far so good after 1 year on the first amp. I going to put the second in a Toyota Matrix with a similar setup.

By Patrick on October 14, 2023 Verified purchase

Just WOW!

First off, I thought I was getting the previous model type r which was like over 50$ diff but they upgraded me to the newest model without telling me (which is awesome).

Secondly, this thing performs!!!! It will vibrate your nose hairs and sometimes causing a sneeze (NO JOKE). on the mrv m500 amp and a 1.5ft box its louder than what my head unit can produce volume for the music. And this is just for 1 alpine type R. couldnt be happier

Awesome Sub!

I am running this sub on a 500 watt JBL amp at 2 ohm and it is bumping. I've only had it for a month but so far it works. I previously owned at JL Audio W3v3 and this thing is way louder and has very similar sound quality for a cheaper price. With just one sub is enough for me and I'm not even pushing the sub to it's max. My car windows aren't rattling but the bass is enough to still turn heads when really pushing it. Really enjoy this subwoofer and I would definitely buy another one.

By Gerardo on October 19, 2017 Verified purchase

Great Speakers

I purchased 2 of these 12" Alpine Type R subs and installed them in a Fox Box underneath in my 2006 Dodge Ram quad cab.
Fitment is great and bass is good.
I have them running at 1ohm from a 1700.1 Hifonics Brutus amp.

By Anonymous on May 18, 2019 Verified purchase

Top notch product

Combined with a second type-r/great amplifier/ and 0/1 gauge wiring,this sub worked wonders for me in terms of handling power cleanly without distortion. A must have sub without blowing the bank

BASS! How Low Can It Go?

These sub is hands down the best one out the collections of subs I have. The overall design and build of the sub is amazing. I really appreciate how Alpine had the terminals on one side and can easily be bridged with a less than 6” inches of wire. I currently have them in a sealed enclosure that is a little too big but sounds so nice. The bass sounds tight and hits hard. I may switch to a vented box to hear and feel the difference.
This sub will not disappoint and is money well spent. I also highly recommend getting the grille to protect the sub.

By SqEarl on January 29, 2020 Verified purchase

Great price

Had been wanting these subs for a while, with help from Travis I was able to get a great price on these. Great subs but even better customer service.

Everything I Needed

Used this kit to run an amp to the trunk of a 2015 Kia Optima. Ended up trimming about 1½ft of excess to help clean up the install. Everything seems to be good quality. Ran the power wire down the driver's side and RCA & amp signal wire down the passenger side to avoid any interference. Plenty of length of everything for a full size sedan.

By Andy on December 28, 2023 Verified purchase

Bad Quality.

I bought 2 of these subs and had them for almost two months and they blew. Had them professionally installed. Should've never wasted my money. Very dissappointed.

By Gage on January 9, 2020 Verified purchase

Amazing! I will never buy any other brand of sub than this one!

I have had many different subs in the past and these alpine type r’s are by far the best I’ve ever had. Highly recommend spending a little more on these than on some other brand, it’ll be worth it

By Anonymous on September 8, 2019 Verified purchase

I love it!

Sounds great! Bass response is awesome! I would buy again.

Excellent buy!

wow, first let me say that sonic electronix upgraded me from the previous gen to these subs for free. that alone will keep me coming to this site for future orders. the subs are great, they pound on my old kenwood amp, so i can't wait to get a beefier amp to push these things. always had good luck with type r subs before, so didn't see any reason to keep me away from these. you won't regret these babies!

Great lows

This sub is the truth. It is putting in work. No problems. If you want bass at a great price this is it.

Great value!

These subs are pretty good, glad I decided to go with them

Great product

Kicks ass, just what I expected from Alpine.. You won’t regret your purchase..

Okay amp for the money

I looked at the specs on the website and it says: S/N ratio >105 db. The owners manual says >85 db. Even that is possibly optimistic. It sounds okay at about 2/3 volume, any less and the noise floor is very noticeable, any more and it starts to smear the highs. In the sweet spot it sounds decent and somewhat clear, still not bad for the money.

Alpine R-W12D4

Holy cow this sub slams! I have 2 in the back of my Ram (under the seats in a ported box). These hit a lot harder than the kickers I've always run and they sound a lot clearer, too. Match them up with a good amp and you'll love what you hear! I'm glad I made the switch to Alpine :)

By Anonymous on June 8, 2018 Verified purchase

Great sound,

Really like the quality sound, really hit hard. But the jumper cables that are provided with the sub tend to fall out. Not a good design at all.

Good kit for the price

The power and ground wire are fine , speaker wires are interesting. One side has square and the other is round which makes it very easy to know what you hooking up to what. Came with everything it was supposed to.

I got this item as a promo for buying my amp. Has everything you need. I would've preferred it to have a red power cable and blue remote wires.

Normally I use OFC but this kit was free for a starter system and has been running good since install. Wires are nice and flexible, lightweight and pretty well jacketed.
