Pyramid Technologies Pyramid PB448X 1000 Watt 4...Strengths: Looks good thats about it and seems to be pretty durable Weakness: Can't be 1000 watts This is not a 1000 watts i don't care what it says on the box it has no power at all. My 200 Watt optimus amp sounds way better than this peace of crap. Don't buy this if you plan on getting a lot of power out of it. 60% of readers found this review helpful.

Pyramid Technologies Pyramid PB448X 1000 Watt 4...Strengths: Seems to have lots of power, and sounds great. Weakness: My amp "pops" when I turn it off! Do any of you other people have this problem with this amp? I have two 400watt 10" subs driven off the rear left/right channels in stereo using the built in sub-crossover, and two 260watt 6x9's driven off the front left/right channels in stereo. It turns on fine, and sounds great, but when I turn it off it "pops"!!! I unplugged the RCA inputs, and it still pops! If I bridge the amp into two channels, and only run two speakers off it (either the subs or the 6x9's, it doesn't matter) the pop goes away. All the speakers are 4 Ohm. However, I want to use all 4 speakers. I'm using 8 gauge power/ground wire. I cleaned off all the enamel on my ground connection, so it is good. I have a feeling it is a problem with my amp, but I'm not sure if it is a defect, or if it is just the way the amp works. Can any of you other owners let me know if you have this problem? Thanks. 56% of readers found this review helpful. Did you find it helpful or unhelpful? Top

Strengths: works great, durable, easy to set up, cheap (cost)
Weakness: look, it looks alright but there are way better looking amps out there.
I like this amp a lot, and the other guy who was saying his amp was a peice of crap. He must have gotten the 300 watt Pyramid Super Blue amp and not this one, becuase it works great for me.
