So I have this old earthquake amp tremor TNT600 which is about 75rms if I had to guess, I cant find specs on it. anyway, I have component infinity pr6500cs and coaxial for the rear doors are infinity pr6502IS. The components are 320 watts peak so about 80rms and the coaxial are 60rms. I think this amp might do a decent job of handling them but I do have one concern. The amp has 4 RCA inputs 2 are for low pass and 2 are for hi pass. Low pass is normally for subs and Im not trying to get much bass out of these 6.5 speakers I really want mids and highs. How do I set this up? How would you do it? Hope Ii make sense...
