Subwoofers and wiring?

Question

If i have two 10" subs in my car right now with an amp, and i have two 15" subs and another higher watt amp that has the same voice coils and all, can i swap them out without changing any of the old wiring?

Answer 1

depending on the rms watts the amps are in difference and the thickness of the wire been currently used, you might want to change the wire.

for the subs,

i usually install 12 gauge wire if its a system running 0-1000 watts rms.

if its over that, i install 8 gauge wire to the subs.

this allows a much better flow of watts on them, plus they look cool instead of having the thin poor looking wires.

Answer 2

the only thing that you might need to do is replace the power wire going to the amp, any time you get into high wattage amps, 4ga power wire is a good thing!
