Sorry, deck has 2 channel rca outputs (front and rear) but also has a sub out (in the wiring loom). I am planning to use the rear preamp outs for rear speakers and don't want the woofer controlled by the front speakers. The converter is 4 speaker wires in and 2 rca out (to amp). The deck itself has built in gain and frequency controls for the "sub out".
Line out converter
Howdy. I just bought a Blaupunkt Sanfrancisco 320 for my little VW. It comes with 4 preamp out (front and rear) plus a "Sub out" and "Sub out GND". I am going to run the sub out through a line out converter to my amp. The LOC comes with 4 wires to attach to speakers, so should I connect left or right (one channel) to the LOC? Or should I connect both left and both right to the sub out on my deck?
