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.....

sounds great

Box sounds great. Only problem is the trim ring on the Hifonics subs wouldn't fit without a little grinding.

Great price

Speaker box is very nice the only problem I had was the face plate was to small for my speakers I had to cut a bigger hole so they can fit.So watch out for the size,dimension on this product. I would recommend this product

Solid Box

this box is pretty solid. i have had it for around 2 months now and its workikng great with my two alpine type s. it feels well bilt and looks nice with the shiny front part.

yes

This box is nice and heavy. It looks sexy and my nvx 12s fit in it. I would recomend this box. I dont like the terminals but thats not a big deal.

Bargain Package Deal

Looks & Sounds Great...Box is put together well & Speakers sound Amazing

awsome value an great look

I just got one Belva BB212BK BOX ,pretty big for two 12" NVX the sound was smooth and had just the right amount of bass

Great looks with great construction.

It's simple and straightforward. The construction is great, and it came securely in another box. Separate ports for each sub. The is the best you're going to get without paying an arm and a leg for a custom enclosure.

Perfect kit

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

By Chad on May 14, 2020 Verified purchase

Ok..

Not even a couple days after bumping two gto jbl in it the carpet started to split... But overall I like the bezel- but only because I paid close attention to diameters and measurements of subs I bought compared to this box's measurements. Would be better if they made it to where you could wire in a series the correct way.

Another GREAT PRODUCT!!

I usually build my boxes but with winter coming I don't have time. So I purchase this one and it is awesome.

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

Nice box

Nice box but once I put the speakers in it the front fence of the speaker box wouldn’t fit over the speakers the holes were to small so I had to pay to get the face trimmed

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.

By Trevor on June 8, 2016 Verified purchase

Great wire

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

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.

Good kit

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

By Anonymous on March 25, 2019 Verified purchase

Great package

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

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

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

By Steven on May 8, 2016 Verified purchase

Huge

Huge box for huge sound highly recommend for powerful subs that need the space!

By Joe on April 24, 2016 Verified purchase

GREAT BOX

Great box. It arrived almost an entire week early to my APO box (pretty impressed) and in perfect condition. My Sundown Audio SA 12's fit perfectly in the cutouts. This box slams with the SA's running at 1500w RMS. No port noise and plenty of punch in the lower frequencies. I would definitely recommend this box to anyone running a medium sized setup like mine. I did have a little issue getting it in the trunk of my E39 BMW but nothing to complain about.

Great sub

fits perfectly behind my 06 silverado backseat and hits great. Love it. Great shallow sub for a great price.

Excellent product!!!

I would definitely recommend this box. Excellent quality, shipped on time, and sounds GREAT!!! You won't find a better box in this price range

This box slams!!!

This is a awesome box well built and very solid worth every penny!!
I put two Sundown Audio subs in it and it slams!!!
I honestly love it so much I am fixxen to order a second one so I can run four 12's in my truck!!
If you don't like rock solid low end bass that makes your car pulsate ,
or bass that hit's so hard it blurs your vision!!
This beautifully well crafted box is not for you!!
I highly recommend this product and Sonic Electronix I guarantee that you will not be disappointed with either!!!

By Rick Abrams on August 3, 2017 Verified purchase

This box slams!!!

This box is amazing for the low price! if you are looking for a heavy well built box that will shake the rear view mirror slam off your windshield look no further!!
I loaded this beautifully crafted sumbitch with two sundown audio 12's and hit it with 800 watts rms and was blown the hell away!!
I would highly recommend this box to anyone who is looking to shake the pantie's off ya girlfriend or melt down grandpa's hearing aid from 2 block's away!
I will be doing business from hear on out with the fine folk's @ Sonic Electronix !!!!

Awesome Box!

I bought this peticular box as it was almost spot on for cubic feet for my JL Audio Subs. This thing is built like a tank. The carpet is good quality and the front glossy part shines real nice. If your looking for an inexpensive yet not cheaply built box, this is the one.

By Anonymous on September 3, 2019 Verified purchase

Worth it

Nice durable box looks an perfomes very well great value

12" SUB BOX

Great quality build! Dual 12" Sub box with individual ports for each sub. Great sound quality!

By Al on February 19, 2020 Verified purchase

Solid construction and looks great

On initial glance look like a good box. Once I dug deeper I could see the construction was very solid. It definitely has some good weight to it. The speaker rings fit the subs perfectly. Great value for the price. I can't find any complaint.

By LocoSiete on March 11, 2020 Verified purchase

Nice box

Well made box, subs fit great and glossy insert is a nice touch

Almost perfect

Bout this box to house two of the new Alpine Type R 12’s. The cut outs on face plate of the box is a little too small for the subs to fit (if you keep the rubber ring surround on the subs). So mounting was difficult. After fighting with it for a while they worked out. Sounds great.

Best Box for the Price

This box is such an amazing value. It looks amazing and is constructed very well. The only complaint is that I had to resize the cut out for my subwoofers to fit. But overall it is an amazing value and I would definitelt recommend to a friend.

Great box

Great box in my opinion. I have 2 Orion XTR 12s in it and they sound amazing. Ordering another of these boxes to run 4 12s soon

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

Solid box

Solid box and it's well built however Rockford Fosgate p1 p2 or p3 subwoofers will not fit the trim around the hole is too small. I had to take off the glossy black faceplate to install the Rockford and it sounds amazing only getting A 4 star do to the faceplate I'm planning on trimming the hole bigger on the faceplate later on.

By joel on April 14, 2020 Verified purchase

Caution!

Most subs with beauty ring or thick mounting ring will NOT fit in box. Will have to cut subs or box.

By David on May 5, 2017 Verified purchase

Pioneer TS-Sw3002S4

I was very hesitant to purchase a sub woofer manufactured by Pioneer but after reading some good reviews of their sub woofers I decided to take a chance. This was my first exposure to shallow mount subs due to limited space under the seats of my friends 370 Sea Ray. I married a pair of theses subs with the Pioneer shallow mount down firing enclosure which is tuned to the subs minimum frequency. Adding some insulation within the enclosure did deepen the sound slightly.

The two subs, wired in parallel so the amp would see a two ohm load, an older Alpine MRP-M350 amp, a Goodwill find that spent the last 3 years in my closet and I consider to be bare minimum power for these speakers, I was shocked at the performance provided in an open air space like the cockpit of a boat. There was a considerable amount of deep end punch, all be it, not as accurate as I typically experience with higher quality subs, they were more than adequate for use in the outside marine environment. Highly recommended if you are on a budget for either a vehicle or outside marine environment.

Built well

GREAT DEAL. Expected way less so I was pleasantly suprise.

By Alan on March 11, 2024 Verified purchase

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.

By Daniel on September 12, 2024 Verified purchase

Sub are excellent for the price.

I couldn’t ask for a better sub for the price that paid. The name of the subs says it all

By Rob on January 6, 2025 Verified purchase

Love there stuff been back several times will order everything I need form them

By Jerry on August 10, 2024 Verified purchase

Nice speakers for the price

Buy 2! One isn't loud enough for a single cab truck. Melted one with a JL 1000w. Bought 2 this time and they hit decent for shallow mounts.

Excellent speakers

Great speakers at a great price. The sound is excellent and they work good. And the good thing about the site is precise on the delivery dates.

This speaker is good for the person that want a little more bass in their TRUCK. Granted, this is for competition use Now!!!! Just a little something for inside the cab.

These speakers are great, hit hardand the sound is very clear!! Thanks

Wired a 4 channel amp up with this wiring kit. Good quality wire and looks really nice

By Ron on May 18, 2025 Verified purchase

Great promo item

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.

By Aaron on January 15, 2025 Verified purchase

Right tool for the job

I wanted to beef up the bass in my 2012 Sequoia as the factory 8" sub was quickly overwhelmed for my use. I looked at numerous configurations before stumbling on the Pioneer downfiring shallow mount sub box. The black carpeted unit blended in seamlessly with the cargo area of the Sequoia. I entertained a few different options but ultimately went with the Pioneer 12" shallow mount sub along with some polyester stuffing.

I mated this combo with a Pioneer GM-DX871 amp. With its 300 watts into 4 ohms, it's a great match with this sub. I added 6' of extra speaker wire to give me flexibility in where I stored the amp in the cargo area. I rarely have the third row seats up but the sub box will still fit.

To get the most out of the sub and provide the best connection, my local shop added an Audio Control interface to eliminate the built in bass roll off of the factory head unit.

After 3 weeks with the sub, I am very happy. The amp's adjustment dial is a must have as i find myself adjusting the sub's output level with almost every song and certainly between sources - BT, Sat and USB.

I listen to rock and classical music with a little country mixed in and this sub provides a great foundation.

Great bang for the buck

I have 2 of these behind the back seat of a 2017 Toyota Tundra Crew max! With the right amp and wiring configuration these things slam!! I have 1000 watts pushing these in total! From 20hz to 30hz they are pretty good but in my opinion where they shine is that 40hz to 60hz range!! Gives that punch to the lower sub frequencies!! If you are on a budget these are a no brainer!!

By Alex on February 2, 2020 Verified purchase

Great value good quality

These are some good speakers. They bass hard if you have the right amp and have them put in professionally. They are great

Excellent product

When put on a quality amp this speaker sounds amazing. Smooth clean bass that you can feel, at all frequencies.

Awesome

Phenomenal service I love those speakers Sonic Electronix they are a great group I've been buying from them for years

good amplifier

good amplifier,works well and is not heated,dimensions are not exact but my recommendation,thanks

great sub

I was running 1 12" Alpine swr-12d2 in a sealed 1 cu ft down firing box in my 02 Silverado and noticed the box was to small and the sub would hit the floor when the bass hit. As to not ruin my Alpine I replaced it with this Pioneer, first the smaller displacement of the sub made a huge difference but also the way the sub is designed it doesnt hit the floor when the bass hits. Good design, hits the low notes, plenty of punch would recommend to anyone with a lack of space ad small enclosure.

11 years later!!! Owned since 1-2015

running them on a nvx 1000 rms 1000.1 nvx mono block. 2 of these bridged down to 2 ohms. At 14.5 volts, Head unit, dps, and amp producing a clean signal via oscilloscope. Run them at full tilt in a sealed box havent had any issues out of them. I listen to all types of music. I will say they have done me very well. Have had them in 2 different vehicles. The a/b class amp i was running burnt up. (I was stressing the amp) upgraded the amp. And these woofers are still running strong. In a down firing box. Wipe there faces down periodically and wipe them down with some leather, vinyl protectant while cleaning the truck. They produce a clean frequencies response using rew software. Using the dsp i can dial them in better. Having used there previous models in a ported mtx box i will say I couldnt be more happy with these woofers.

Heck yes

Sonic gave this to me with an order. What more to say.

Box was exact spec for the 2 12s. Sound quality is good and it hits lows nicely

Free amp kit

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.

By Chris on January 11, 2025 Verified purchase

Love it

Added the JL audio w3, they fit perfectly and sounded amazing!

By Jesse on August 15, 2024 Verified purchase

Beyond expectations

I have to agree with another reviewer who stated that this speaker does a great job of supplying that Impact "visceral" subsonic sensation that goes beyond just low bass.

Bang for the buck

This amplifier delivers plenty of power for the price. I have it on 2 pioneer champion series 10s and it sounds great.

By Fred on February 26, 2017 Verified purchase
