Hi everyone. Nice forum you got here. Very busy I can see. Anyway, down to It. I have a 2010 Chevy equinox with the base audio system. This means I'm running 6 standard speakers 2 tweeters 2 front door speakers (maybe 5 1/2's) and 2 rear door 6's. Now my equinox has a factory installed sub but it is not active in any way. Dunno why gm put it in if they weren't going to hook it up? Anyway my main problem is ... I want to throw in a PAC line output converter (4channel). I would just hook it up directly to the factory subwoofer wiring to keep my mono frequency correct BUT as I said before there is no active subwoofer wiring from the stock amp. So how could I make a mono frequency so I'll be able to hook up my class d amps?? I've been searching for help for quite some time about this
