i just got for free a 150 watt jbl amp. my friend bought a crap car and it was just in there he said take it. my audiovox amp toasted about 4 weeks ago from a defect so i was wondering something. the amps popularized as a sub amp, it's got a low pass,normal and high pass. it's got a left and right channel and i wanna run my 2 infinity 6 inch fronts and 6.5 alpine type - s for the bk. my thing is how can i run this cause my rears i don't think can take as much power as my fronts. but if i make my fronts left rears right will it sound messed up? also the amp should be ran in normal or high pass mode?
