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.

Tiny, whimpy little amplifier. At 0 gain, it's capable of proving enough power to get approximately 1:1 volume from unpowered headunit output to weak headphones. Takes full gain for more stubborn headphones like my shooting muffs. With a little creativity, this amp could find some other uses, but it seems perfect for adding headphones to the car. Well, sort of. Audio quality thus far is a bit crummy when the car is actually running, so I may need to tinker with the grounding or add filtering. Compared to BOSS's other products, this one seems lacking the included stuff department. Would have liked RCA output capability in the box instead of having to buy it myself. (Screw terminal RCAs are awesome, btw) Mounting gear could be a little more diverse. I don't want lag screws sticking out of my plastic. Thank goodness for mighty putty. *edit* Nevermind. This amp has the longevity of a gnat. I thought my remote wire or ground was having an issue so I proceeded to buy a filter. Finally got the filter and after some tinkering that included the extreme of tapping remote to +12V, this thing is dead. That means it was dead in like two or three days.

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
