2.0 out of 5 stars Nice Four Channel Amp, March 9, 2010

Nice amp. Easy connections. Easy adjustments. A good size for tucking under the seat.
You only get the amp, booklet, rubber inserts & some screws. No wires, no connectors, so don't expect them.
The amp works fantastic after a week. Installation is as easy as you make it. It is long, but isn't thick or wide. Even when the power on wire came loose, it still came on nice & strong. You can pay more for other amps if you want. Keep in mind that this isn't bridgeable. They even say so in the booklet (downloadable from site). It runs cooler than other that I have used.
Adjust your stereo as you want, than change your mind. These turn easily, so you can do it as you sit in the front seat. One thing I don't like, is that there isn't a cover for the connections. I'll have to fabricate something.
The three leads are soldered so you can just heat them to connect, nice job.
Is the whine because the amp? I don't know. I already have one RCA suppressor on each patch cable & now need one to this, sigh, the fun of amps.
Anyhow great unit & a great price. Nice weight to it as well.

Update: Had some whine, did a return on the amp, but "no problems found." Pyramid suggested I send it in to them. After about a month of turn around via shipping, it came back sounding great, till the other day, when it just died. I tried resetting it, checked fuses & the like. Nothing, dead. It isn't worth another 30 dollars in shipping fees (to them & back), to see what happened. I noticed some condensation on the "glass", but nothing out of the normal for a vehicle in the cold.
I wrote Pyramid a note, but they haven't answered. I am surprised that it died like that. I know the first return was more of a waste, but the amp did sound even better after it came back. So I'm taking it that its just a suck unit, & will stay away from the various other brands they make there & look for something else.
So less than a year on it is not good. Hopefully you don't pay more than 40 bucks for it.

I cannot find the proper words to describe this item. Bad, really bad. It does not work good. Even though I had to connect a noise suppressor I could hear many noises thru the stereo.
