ive got 2 10" and 2 12" audiobahn subs with bout 2400 W rms total with a 12 farad capacitor to boot in the back of my '97 tahoe. the vehicle is new to me so i havnt finished wiring it yet. i got all the wires laid and ready to go but the ground is not connected and neither are the RCA's. Since it is a factory deck yet, i also have a converter to splice into the speaker wires for the RCA's. Any suggestions for the best place to connect the ground and how to run the RCA's through the dash?
