pleasent surprise.

I'm using this amp on a JL Audio 10W0v3-4 in a Single 10" Sealed MDF Enclosure (10SQTC) and it thumps. My jeep has never sounded so awesome! I have to admit I was nervous ordering such a cheap amp, but this thing is delivering. One issue I did have early on was the set screws used to clamp the speaker wire in place.... they are Phillips head and way too shallow to actually tighten the set screw properly without stripping them (I know because I did). I just went to the hardware shop and picked up some 8-32 machine screws and they do the job great. This amp looks nice, the logos light up and are cool at night, just hope they don't get me pulled over.

Great Amo

This is truly a phenomenal little amp. It's powerful and compact, runs cool, even when bridged, and it sounds great with no audible distortion about 80% power. I've never pushed it to full capacity because quite honestly, that's asking for trouble, but that's a whole other issue. I've been using it for about six months to power two 12 inch subs rated at 200W RMS bridged at 4 ohms and it does a wonderful job with them, and produces all the sound you would ever need. Plus its small footprint fits great in my Ranger and the blue led emblem matches the scheme of cab and cap lighting I have. All in all, this is beautiful looking and sounding amp that fits anywhere, as long as it fits your power needs.

Great amp for the price

Easy to install. I haven't tried this amp for the lows but for the highs it is a great amp. Really loud amp. I was really impressed. Have to be a little careful with the white part of the amp as it sinks in a little. Still a great amp for highs. I would recommend this amp and already have!!

works fine, small, good value so far

For the price, i cant complain much, i wanted to see how cheap i could add some low end in my truck so i bought this and a lanzar 8 for well under $100. It sounded okay, enough to make the music sound alot better but nothing crazy, then i hooked this up to a coustic 10" I was a little more impressed with it, it sounds pretty good at reasonable volumes. The light up butterfly or whatever is kinda clowny lookin, and i easily pushed my finger through it on accident handling the amp, so be careful. Can't say how long it will last because ive had it a month.

The Car Guy

Excellent amp. The price was right and I am happy with it. It pounds my diesel sub like nobodys business. Sonic Rocks. Always finding good deals on Sonic website.

Small price...BIG sound.

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. I have this amp powering a single 12" and I work it hard. Never once has it stuttered, overheated, or even batted-an-eye. Great choice for guys on a budget. My ONLY complaint is that it will not carry a 1-Ohm load. Other than that, it's great.

Very impressed!

I am using this to power a 1230w infinity 12" subwoofer and I must say for the price I am very impressed.

For the price, it pounds!

I have owned this product for over three months now and have only a few minor dislikes. When I received this amp I noticed the paint on the removable panel was pooled and runny. Other than that I have loved the amp!

so far so good

This is my first amp and so far very impressed. Im running 2 subs at 115w rms (saving up for a 200w). it is relatively small which impressed me even more. I'm not a bass freak but i think this is a very good amp for a starter.
