Pyramid is a low price point amp that is rated higher then what it can really push. I know because I had got one through Crutchfield and through getting another two (warranty-they fried) realized what I was dealing with. My moms used to say pay peanuts get monkeys. In your case you got hooked up, your stoked but got to deal with the grief. In the case with Amps they cost but generally the more you spend the better they are. Pick one that is right for your application. I suggest Diamond Audio Amps, and for a little less Rockford Fosgate was pretty good- I just put in a 4 channel RockFosin my girls honda and it works great- almost 450 bucks though...The Diamond Audio stuff is sweet, little more spendy but as good as it gets -
