  • Breezy,easy
With us my wife and I it was a class c rv application. It does not take a technical person to understand the straight forward function and installation. It was an ease to hook up and absolute breeze to listen to with the depth and clarity It provides to our system. Depth meaning bass .. clarity meaning overall with highs at appropriate volume level and equalizer settings. Pyle has on of my favorite products for over 30 yrs plus. And in this day in age it is hard to find good quality and low in cost. But Pyle has only gotten better over the years. Very satisfied customers in california. ... show more

  • Need a small car amp? Bingo.
None of the cheap car audio amps were below 70$. Low and behold this little guy just popped out of no where. In the 20$ range... huh? Yea i thought so too. Got it, installed, set crossovers to my speakers ranges. Sounds bichin'. Other reviews say its not 400 watts... maybe? But i couldnt get my stereo to 27 of 65 w/out clipping. Just terrible. With the amps gains set to jist the 1st notch - Im able to get to 57 w/out clipping, and thats way loud. Just need some tweets now. Great product I believe (havent had more than a few days, time will tell) - but great product thus far. Cheap Quality w/ a "marine" stamp on it.. for boats i guess, works great in a car. ... show more

  • Waste of money and TIME!
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. ... show more

  • Decent amp for the price but not highest quality
I installed this on my boat as a cheap solution to run a bit more power to my 4 speakers (2 Alpine & 2 Fusion). Installation was easy (but I've wired a number of stereo systems and amps before) and it looks nice, but I would rate the sounds quality as just OK. Everyone knows in the amplifier world that all Watts are not created equal, so don't expect the volume and quality of a JL Audio, Alpine, Soundsteam or MTX. ... show more

  • More power than I need...
Out of stock... I bought one. My friend and I installed. Good and clean. So, we bought the last four.

  • Expect to be hugely underwhelmed.
You won't be disappointed if you don't expect much of anything at all. No real power at all. More in line with 20w per channel in my professional opinion as an electrical engineer. Overpriced even at that level. Expect to disappointed and you won't be disappointed. 🤪
