I have a 94Z CONV. I have had an aftermarket system put in, about five years ago, with Phoenix Gold wiring, I believe. The connector to the radio was cut for the new harness. I bought a GM 1988 and up, 21 pin connector, to fix that. I know the speakers run 4 wires each, do I need a different conn. for that or will the stock conn. work? Also, will the Monsoon work in a 4 speaker car and can/how would I wire the Monsoon sub-woofer in there. Thank you.
