Hi There

I currently have a 4channel amp, with one SVC sub and a set of 6x9's running off it, i also have a set of 4inch "door" speakers which are currently running off my head unit. The issue i have is that i can pritty much hear nothing from those front speakers, is it possible to run these speakers off that same amp? and will this solve my issue?

i look forward to the responses

thanx alot
