BOSS Audio CE102 Chaos Epic 100-watts Full Range Class A/B 2 Channel 4 Ohm Stable Amplifier AD

I am using it as a bass booster for my home theatre woofer. It works free. Cheap but of great quality.

Muy buena fidelidad de audio y excelente calidad de ensamble.

Excellent little unit very straightforward and compact easy to understand instructions not overly complicated. Works perfect for adding a little extra kick to either Factory speakers or my single cab truck with some speakers behind the seats was able to slide the unit inside the dash and not have it hang out anywhere

Use this in random with a Kicker line level adapter to add the factory sub to my car. The woofer isn’t rated for much more than the rating for a single channel on this amp, so i get ample power out of it for my use case. The low pass filter also works exceptionally well. It’s a bit larger than a bar of soap in size so it was very easy to install it in the same area the factory amp would have been located. It sounds good, runs cool, and does exactly what i want it to for $30.

Was nice and compact, but failed two months in! Started by shutting out one speaker, the the other

Didn't really expect much, but it brought my subs back to life on my 987 Cayman. The old amp was about 40W per channel, so 100W total should work. With sensitivity at it's lowest and the high frequency filter on, it powers the original sound package plus speakers well and has no distortion. No need for a more powerful unit for the old speakers and for such a small car! FYI the amp is really tiny
