I’ve had this amplifier for a good couple of months now it hasn’t given me any problems. I’ve blew a couple of fuses in my car but that thing never gave up. I’m running 12 gauge wiring same as the speaker wire and power wire ground wire ACC wire and it’s still output wires don’t get hot. It also doesn’t get hot. I wouldn’t recommend for a boat as it is cheap but for the money, the audio quality is great and as long as you keep it in a car, it will do just fine. I have three amplifiers and I can’t tell you how much work I’ve put into my car if you’re looking for something simple to use that’s not complicated do this amp you can run it off the original head unit wire

Little amp just works. It comes with high level inputs. Easy to install. I’ve splashed it with water from the hose while cleaning the boat and it hasn’t seemed to affect it. Is it 100 watts per channel? Idk. I have 3 skar 6.5s and they sound amazing with it, with amp gain all the way up they are still asking for more. . Plus two Rockville wake tower 6.5s and even though they are rated at 250 watts per unit they don’t like it with the amp the way up ,currently their channels are set to half. Two of the skars share a channel. Will see how it hold up this summer but as for now It gets 5 stars.

This thing didn't work right from the start. My more expensive amp went out after about 3 years, which is expected in a boat in Southern Florida. I replaced it with this, thinking it'd be "good enough" for a couple years when I'll have to replace it again, anyway. First, the power and ground wire receptacles we're far smaller than the previous amp, so I had to size down the power/fuse and ground wires. Second, it had so much electrical interference/feedback noise that I could only listen to music when EVERYTHING else in the boat was off. This wasn't the case with the previous amp, but I started digging into the wiring to locate the likely bad ground. None found. I bought expensive wrapped RCA cables, and that seemed to help a little, but still feedback when an engine or pump were running. Third, this is definitely not designed for the marine environment, despite the description! Stuff rusts in Southern Florida, but this thing shouldn't have started rusting within the first two weeks if made for MARINE use. It was installed inside the console and kept dry. Replaced with another more expensive amp, and everything works great. This is in the landfill, unfortunately. I should've given up searching for the bad ground and returned it while I could. DO NOT BUY.

I was a little nervous about buying it because of the complaints about alternator noise. I took a chance and so far, it works great and no alternator noise. I power four KICKER 6.5” 2 way speakers. Good little amp.

Pretty decent little amp for the money. Only problem I had (maybe my fault for poor ventilation) was the amp would cut out or lower the output volume after use sometimes. I’m assuming it was getting hot in my front deck storage of my boat. If you didn’t need something super loud this would be a pretty good amp and it’s fairly compact.

Loud but can't get rid of the alternator noise I wired it every way I can and always has alternator noise coming through the speakers brought it to a audio shop and they were unable to get the alternator noise to stop I've installed many amps and never had a issue contacted pyle for help and got no response if your system don't have a alternator or any battery charger it is perfect but if it does don't get this one I thought it was the amp causing it at first so I got a replacement and it does the same thing I recommended but at the same time I don't

I have a WM7000 down below driving 2 older Bose speakers in the cabin of my sailboat with two Polk audio waterproof atrium 4 under the dodger on deck. Like most single din marine stereos, The WM7000 does not have the power to adequately drive these speakers. Adding the Pyle AMP produced amazing results. The unit is solid and well made. The terminal strips are top quality. Installation was easy. Integration with the WM7000 sound control features using RCA jacks is excellent. This unit comes with a 20 amp fuse…As a sailor and anchoring overnight without an engine running I was concerned the amp would be a power hog. But with my setup running all 4 speakers fairly loud I am seeing only a 1-2 amp draw which is no problem for my house bank. Much has been made of the unit not truly being waterproof. I agree with this but suggest that mounting an amp, or really any electrical component, in an area exposed to constant wetness is stupid - put it out of the weather.
