  • Cheap, with good output can’t ask for anything more.
Honestly the amp works great. Simple features but does exactly what it’s supposed to. Have it hooked up to two Sony 6x9’s and 6.5’s works well and doesn’t over heat. It is compact so that’s an amazing plus, only thing i would say is that you do kind of have to press your fork fittings in with the amp wires. So if you run anything higher than a 4g you might have to crimp the ends just a little to fit. ... show more

  • Perfect
I was a little skeptical of a full range class D but this thing is awesome. Sound is crystal clear with plenty of power and no noise. I got it to balance out my system because my bass is crushing but was running speakers off the head unit. I didn't know if it would make a difference but it sounds right ... show more

  • High quality considering the price
I did my research before purchasing, and people were getting higher numbers then the rated power. So that’s absolutely a plus considering most of the amps on here even the “best sellers” don’t even reach 25% of their rated power. Pros: very small footprint considering the output power. Good power, no lack in sound quality, very reasonable price, looks very nice. Cons: all spade connections, different setting for channels A and B. My “suggestions” (I guess?) I REALLY wish both channel A and B had matching frequency filters. I believe A caps out at 200Hz and B caps out at 750Hz. It would be nice if BOTH could be adjusted to 750, considering I wanted mine set at 500Hz on both channels. Hens the passive RCA filters on channel A.. I thought it was weird that the positive terminal was on the inside rather then the outside, all the amps I have or have installed the positive terminal is on the outside. I may have had to go into my fuse drawer for a couple 30amps because I’m a creature of habit. Not really a complaint or suggestion, more of a “hey if you’re reading this check before you wire”. But overall, I am extremely happy with this amplifier. It has a MUCH smaller footprint then the old Alpine amp I was running, giving me space on my amp rack for more stuff in the future. I plan on purchasing a recoil monoblock in the future to give that a shot, and I’m very excited for that too! ... show more

  • Exceeded my expectations.
I installed this is a 2007 Chevy Tahoe. I had replaced all the speakers, but the the sound was still very poor, so I decided to bypass the factory amp install this Recoil amp. I’m glad I did because the sound is so much better. I can now hear the mids and I now have bass. I was going to install an aftermarket subwoofer, but I don’t need it now. As you can see in the pic I ran the set of RCA wires from my aftermarket head unit for a future sub, but I don’t think I need it. I read many reviews on the Recoil amps and there seems to be a consensus that there is no sub that compares for the price. ... show more

  • Excellent value
Great value for the money. Clear and powerful. Pushes the speakers on my motorcycle above any wind and road noise at every speed.

  • Seems small for what it puts out
It does put out sound and hasn't overheated yet so yes it's worth what cost
