I have a rockford 12" sub and an amp left over from my old car, in my new one i have the Mach 460 system, can i hook the rockford and amp up to the system, or just the sub with out the amp?
Yes you can hook up ur amp and sub in your new car but you do need a box to convert ur speaker level inputs into rca cable ends like(Tsunami RCA Line Output Converter (FLLOC600) ) Then just wire you the amp and sub like normal.
