I bought a new sub and an amp. I don't want too buy a new radio. How could I wire this sub and amp to a factory Head unit since there is no RCA out on my Head Unit.
if you have a mono amp, it should have a LPF built in. this may not be the case for all amps though. what amp?Using a line out converter on the rear speaker wire, will this mean I will then need a crossover so no high frequencies reach my sub.
