First things first, NO, this amp is NOT a massive powerhouse. It's a fullrange 4 channel amp that takes up almost ZERO space, has 4 channels, 1&2 have a high pass filter, 3&4 have a low pass filter, and it has 2 separate RCA inputs. That combo is VERY rare, and the price is very acceptable for the feature list. On to the review! I'm using this amp in a "Tool box" speaker system I built. I have 2 SLA batteries wired in parallel as a power source, I'm using a balancing RC battery charger as an internal charger, it outputs 6amps and will balance the batteries at 15v. I'm using an old walmart special touch screen bluetooth head unit as the audio source, two Skar EVL-65 D4's wired down to 2 ohms each on channel 3 and 4, two SSL 6x9's on channels 1 and 2, both channels are set to their respective crossover. I need to find a better tool box to package the whole setup in but for now the concept works a little too well. Our downstairs neighbors (they're on the 1st floor, we're on the 3rd) said they could feel the bass when I turned it up 3/4 of the way. I've got a bunch of trucks at work (I'm the fleet mechanic) that our guys want a better stereo in, this amp will be getting put in every single one of their trucks, if corporate approves us modifying the stereo systems.

It's been over an 1-1/2yrs later and the amp is still running flawless, and I'm still convinced that most of the bad reviews are those expecting greatness from a very cheap amp or improper hook up. Im not the best installation guy but I also only bought the amp to run tweeters and it's still working. I wanted to write this review early based on reading other reviews stating that it has noise.(I have been into car audio since 97) Well I hooked it up and I have good gauge wire and found a good ground and I haven't heard any noise in this amp, so I'm believing that most that have a noise problem with this amp is because you don't have a good ground or thicker wire. (((I have the Black amp if it means anything))) I have the amp hooked to two DS18 super tweeters and its doing what I need it to do so far. I will update if anything change, but I just wanted to state that most of the noise problem is probably your wiring and location of your ground.

Update: I purchased a Taramps 400 watt amp to replace this. I was able to remove both the noise filters so problem was definitely with the amp. Also the Taramps is much louder . This one wasn’t much better than the sound from my head but the Taramps is a big improvement. For anyone looking to replace this amp with something better I would recommend the Taramps 400 watt rms amplifier sold here on Amazon. My speakers are 50 w rms and 65 watt rms and work great with it! End update. Lost a channel in the rear speakers. Switched RCA cables and speaker wires. Still no working. Decided to use as a 2 channel amp and discovered no matter whether I used 1 and 2, or 3 and 4, there was always a channel not working. Since it wasn't the RCA cables or the speaker wiring, I decided to remove the unit and threw it away. The head unit I have supplies 22W RMS and sounds fine. This amp was way more trouble than it was worth. I will mention also that I had to use ground loop filters on both sets of RCA cables with this amp. Funny thing is I have another amp powering my sub and that one does not need the filter. I also added a 12v power filter for good measure. The sound was a whine that increased with rpms. Tried grounding the whole system same spot and still had whine so i added the filters.

I ordered this amp to add a few tweeters to bring out the clarity in my setup, (4 sundown X8s on 2 Skar RP1500s) so this amp was only something cheap to run 4 Rockford Fosgate tweeters I purchased and when I opened the box I noticed almost all of the screws in the amp were just sitting at the bottom of the bag that the amp comes in, then I noticed both of the high level input wiring had already been cut back and had different wiring wrapped around it, since I didn’t need ti use that feature on the amplifier I still decided to hook it up. Amp gets power and receives a signal but all sound coming out of the amp to speakers is highly distorted and not a stable sound.

Purchased this amp as a low cost replacement for a old amp that finally blew a cap and stopped working. Didnt expect much from it, it was cheap and compact, which is exactly what i was looking for. To my surprise, this amp is much more than i expected...It is very clear running good quality RCA's and 8 Gauge wire to a solid ground. I have this in our boat with two 6 x 9 infinity kappas and two10 inch JL Audio subs and have no issues at all.. It has plenty of punch for a low cost amp and even without a noise suppressor, it is very clear. Most noise issues are not due to the amp, they are due to bad ground.
