Currently I have I have one ported JL 12 hooked up a JL G Series 1300 Mono hooked into my Pioneer HU , but am thinking about upgrading to 2 12s. Can i use the same wiring and amp by any chance, or does a whole new install need to take place?
Also what effect will having two subs connected have on my stock battery opposed to just one.
