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

5 Stars without a doubt

Let me cut to the chase here! These subs are the bomb! All of JBLs products are wickedley underrated! The old saying is "You get what you pay for" this is not the case at all here!! You get wayyyy more than what you pay for! I have two of these hooked up on a Kenwood Kac-9106d ( 1000 watts rms) at damn near full power! That's almost 500 w rms a piecmye! They're onlyrated at 350 w rms a piece I'm pretty sure you can do themath! Jus sayin this product is well worth the bread!!! You couldn't go wrong at allll!!! Very happy with the product! I will now shop at sonic anytime I need anything for my vehicle

It is GOOD

Awesome subwoofers! I have 2 of them and i put 900W -145 DB in 72 liters of box! My car is Nissan SILVIA S-13 (sound POWERED by Kixc 1900 amp. & 2 bat.-Optima Ellow top 55a & Stinger 1500

Sounds awesome

Installed this in my 2010 Subaru Legacy to replace the horrible sounding factory Harman Kardon sub. This one is great, especially if you like SQ! Hits hard, fast, and you can feel it. Very accurate sound, and a great price! Get it.

Solid, powerful low end from JBL

I actually have two of the 8-ohm units run in parallel to a 4-ohm plate amp in my home entertainment center. The units do not benefit from the acoustics of an automobile; they have to fill my 435 square foot living room with bass from movie soundtracks and do a fantastic job of it!
PROS: They look great, they sound great, build quality is very, very nice and solid
CONS: none that I found

I would definitely buy these again!

these things rock

I got these two subwoofers about a month ago been breaking them in. Today was the the first day that i cranked them up and they were slamming. they are hooked up to a soundstorm 2500 watt amp. These subs are GREAT

Sounds great

Excellent sub for the money. It is well built. Not quite as potent as my Alpine Type R, but that was expected, and this is much cheaper than that subwoofer. It has good sound quality. Currectly running in a ported box at 34hz, but I think it would sound better sealed in my setup. Seems to be a bit power hungry. Good addition to any system, but don't expect to shake the block with only one.

This is a great buy

This puppy, pushes 350RMS, I have two powered on a 1200 peak amp, they really get the job done, after a while you should turn it down though, because it gets extremely loud!!!

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!

Great Sound

The speaker has proven to be excellent quality and sound.
Well worth the purchase for those looking for a sub of this size.....

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.

Best sounding subwoofer

Over the last 7 years ive owned over 30 different brands, sizes and models of woofers. For 100 bucks this woofer will sound better, thump deeper and last longer then most within price range. @ 350 watts rms you can easily power two and quake the dead, If your looking for good juicy full thick lows, Heres your woofer

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

Not Bad for the Price

Powering one of these in a 1 cu. ft. sealed box at a 2-ohm final load to a PPI ION 5-channel theoretically providing 350 watts. While there is a clear difference in SQ compared to the very high-end subs in my other vehicle, this sub is a good performer (especially when factoring in price). I find them to be smooth, fast-acting overall, and it will get loud off of just "350 watts" (or whatever the little PPI ION realistically produces. At least in my box and vehicle with my amp, it doesn't get as low as I'd expect a 12" sub to go but everywhere else it's pretty flat and natural sounding. As for build/finishing quality, this is where I am not impressed. Properly built subwoofers will have a screw hole that is perfectly directly under the center of the dust cap when the logo is level. In my case, when the logo is level, the lowest screw is slightly to the right. In addition, the ribs on the cone also do not make sense. It is as if this wasn't assembled with alignment in mind. This is something I notice but nobody else will notice, I'm sure. I really don't get the continuing use of dual voice coils in car audio when a single voice coil can achieve the same thing, but the speaker wire terminals were of the banana plug screw down variety

Great wire

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

Works like a champ

I've had one of these in my truck for a little over a month now. It's crazy loud, goes really low, and can handle a lot of power. I highly recommend this product! This is definitely the best sub at this price point.

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 SQ Amp

Just got this amp installed. performs great Paired with My IDMAX 12" D2 @ 1 OHM. I usually have Two Subs In the Trunk but decided to run just one with a sealed box. Without a doubt this set up is more powerful than my last. This amp gets really hot because it has only two heat fins. Can not run this amp with my seats up. the wiring is 100% NVX OFC 4G wire with tight connections and a 1F Capacitor. Durability rated at 3 stars due to this overheating issue maybe would be two stars if this amp fails on me soon. I love the Power and Grace idea that Image dynamics stands by but the thermal design is killing this amp. I don't know if I would buy this amp again. I'll try setting up a forced cooling solution for the time being.

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.

Very nice love what I got came two days early couldn’t ask for more

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.

wire kit

I have used sonic for years and all their products worked as promised, knowledgeable staff, very good prices and you can depend on their products stats being correct including watts and specs!!

Good kit

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

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

Hits hard

I unerder estimated these subs power these with the right amp and you'll
Be heard from a block away

Decent Product

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

JBL. GTO1214d

I would recommend this product.
It has great sound easy to follow instructions

Excellent amp

This amp rocks paired with the IDQ12 it is driving. This amp has some power and I only have it turned up only halfway. Once I get around to fully tuning the system and crank it, my neighbors will probably hate me. I'm very satisfied with the quality and performance of this, now just need to add more matting to my car to kill some resonance.

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

Excellent

Bought one of these to replace 2 Kicker Comp10s that I've had for 4-5 yrs. I have it hooked up to 300w (Kicker ZX300.1) and this one pounds louder and sounds much smoother and much better overall than the Kickers did together. I absolutely love this subwoofer. What makes it better is I got this on a great deal (20% off $79). I cannot comment on durability as I haven't had it long. I would for sure recommend this subwoofer and Sonic Electronix.

Great valule

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

love Jbl subs

These subs hit hard. I have them in a sealed box and they pound. I am using them with a Crunch 3500.1 and I actuly need to do the Big Three Upgrade as well as a battery and alternator ugrade. I am wired in at 2 ohm and these subs are taking the hit. They sound awesome. DO NOT FORGET TO BREAK THEM IN PROPERLY!!!!

Excellent subwoofer for the money. Great sound quality.

I had been using a pair of really awesome old school Orion XTR 12's from 1999 before purchasing these. I sold my 97 Crown Victoria with the Orion's, and the rest of the stereo system, in it. I started new with a 2005 Crown Victoria.
I read reviews and specs for these JBL GTO1214D's and purchased them here. They perform as well or better than advertised. The sound quality is awesome and they have plenty of punch. They easily sound as good as the Orion's I had with about the same amount of power (approx. 700-800W each) . Sensitivity is 93 db on these JBL's, so they sound good even at lower volumes - you don't have to crank the volume to hear the bass.
FYI they are in a sealed enclosure with 1.25 cu. ft. per side. I also split a bag of polyester fiberfill into both sides of the enclosure. For those who don't know, adding the polyester fiberfill inside the box slows the sound waves down and, from my experience, extends the bass notes and smooths out the sound. It made a night-and-day difference with the Orions I had, so I automatically put the fiberfill in with these.
I definitely recommend these subwoofers to anyone unless you're needing monster SPL for sound competitions. If you put several of these together, they might be good for that, too.

Awsome sub...

Awesome value for the money. I have this sub installed in a vented box, powered by an mB quart monoblock amp and it is really loud and clean. Very happy with this sub.

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

DAMN

I just recently got these hooked up and they slam. I mean back massage slam. Still not broke in , AMP turned up about 50%, bass knob on 0, and its on a factory head unit with a bs equalizer. SMH. Running them at 1 ohm with 800 watt pioneer amp. I cant imagine how they are gonna be when they are broke in and i turn everything up. $130 for 2 of these shouldve been more like $230 for 2. rearview mirror is useless. ppl hear it and say they boom but dont even know they aren't doing near what they can. JBL did it again. if you want bass then after you read this add them to ya cart ASAP

ID Q600.1

Paid 150 for this bad boy. Had for 4 months strong before I decided to send a 5 hz sine wave throw it and blew it. None of the fuses even went. Worked well with the sundown E12. It wasn't very punchy though... I don't have good electrical and I'm not exactly sure if that was the problem but it seemed to excel in constant notes. It would get very hot as well, which may be the dirty power's fault. Definitely did rated though. Being class AB it was very inefficient. I keep voltage just as well with my current MB Quart onx1600.1D at near full power. Honestly, I wouldn't recommend it unless you're going for a system with good brand names. Can do much better at the same price and opposed to popular consensus I think my class d sounds better, but it has a lot more leeway too. It looks very classy and high quality though. Indifferent

So far so good

They work perfect in the sealed box as part of the deal. They are a perfect match for the west coast customs 1500 watt amp. It would be nice if the terminals were closer together so I didn't have such long wires in the box.

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.

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.
