A excellent 4 channel.

Have this in my 07 dodge charger and it's great. The amp hasn't yet went in protect. It also doesn't require Alot of power and it's loud and clear.

FLI Audio amp review

I have used two of these bad boys... they are great for the price. Compared side-by-side to another high dollar amp its not as great but is also a half the money. They are very durable except in high heat the glue for the face plate comes loose. I would recommend this amp any day.

Bumpin'

I installed this under my back seat of a '69 beetle. I have it hooked up to 2 boss 5 1/4 and a Polk dx12-4. The sub sounds amazing, but I think I fried the speakers, my own fault though.

The controls are easy, you just have to spend a little time tweaking it to the nitty gritty. A plus is that my headlights don't dim, and I don't have a capacitor installed yet.

Only con so far is that it doesn't come with an alan key or a remote. But hey, you get what you pay for and this is a good bang for your buck.

Good value

I installed this amp to run my front and rear 6 1/2 infinitiy speakers. The amp drives the speaker great, no problem with the sound. The only issue I have is with the construction of the amp itself. I had the face of the amp come of due to the Texas heat. I have the amp mounted vertical in my trunk, so i had to glue the face back on to make it stay. Other than that for the money it is a good product.

Ummmm.....

So I got this amp for a good deal. Hooked up the amp, to replace a 2 channel Kenwood. Alternator whine, popping and cracking at mid volume. I did a big 3 upgrade, ran reference ground, and soldered all connections, rca's on other side from power. Nothin would solve the issue. Hooked up the kenwood again and no problems. Amp was bad.

Low Price...but BIG results.

I saw the Fli demo car at the USACi World Finals and was truely impressed... so I outfitted my Chevy HHR with all Fli equipment. This amp is really impressive. Small size. It looks really clean and can really get the job done. Perfect fit for guys on a budget.

Pretty decent for the price!

Overall, I think this amp is alright. You get what you pay for in car audio, and let me tell you I didn't really expect much out of the purchase. It has been doing a pretty decent job pushing an FLI 10" subwoofer, as well as 6.5 pioneer comps. I really appreciate how small the footprint is, and its somewhat ugly exterior is easily hidden underneath my seat! I absolutely love that all the hook-ups are located on one side, it makes for a really neat, clean install! I've only had it for a few weeks now, so it is difficult for me to judge the durability--so far so good. If you want a REALLY cheap priced 4-channel amp that does its job pretty well, this might be your choice. Please though don't expect the world out of this little guy, you may be a little disappointed.

proud owner

Accidentally shorted out one of my speakers so half the amp blew immediately. Still puts our great power and sounds amazing, regardless of only being able too use two channels. Proud of this little amp.

Great little amp

To start with this is a great little 4ch amp. Sound's clean last long i've had it for 5 years now without one single issue. I would highly recommend it if they still made it
