Summary: Pyramid has a history of advertising their products at "peak" power instead of RMS (or continuous) power. What is peak power? In the DJ world, we referred to it as "WLS" power - When Lightning Strikes. So, why use peak power when everyone else uses RMS power? Because your product is so weak and of such poor quality that the only way you can sell your product is to oversell its abilities. Buy Pyramid at your own risk.
Summary: Don't be deceived by the picture, the amp is actually much smaller than it seems to be from the picture. I bought this amp for my little brother for Christmas and I felt so stupid when he started playing on it because it sounded so awful. If you want minimal sound quality and volume then buy this amp. But your best bet is getting something worth giving.
Summary: The only reason I have one star on this review is because Amazon would not allow me to enter no stars. I bought one of these on a whim years ago when I didn't know any better. Not only is it a useless, underpowered piece of junk; the one that I bought died after just a few months of use. And I wasn't playing it regularly either. I would just hook it up every so often for about a minute at a time to test out electronics and wiring.
Summary: This product is advertised at 150 WATTS. More like 5 Watts. You definitely will not be bothering any neighbors with this amp. Very cheap built. This amp also is advertised to use a 6in speaker, however, a 5in speaker is actually installed. If you're looking for a minimally functional TOY, then this amp will fit the bill.
