hi, i'm new to bass and im after an amp. unfortunatly i just bought a nice 12" sub and car amp and now i cant afford a bass amp. so, i was thinking i could temporarly use the car amp and sub. i can power the sub in the house, no problems.... but im unsure how i'd put the signal into the amp. It has a high imput plug and a low input with left and right rca plugs. if i plug the guitar into the low input on the amp would i blow somthing up? and if anyone has tried this before id like to know how bad it sounds.... i also have a house amp and 2 speaker boxes each with 12" drivers + tweeters, but i figued that would be worse.
