mr_bock said:I added a Alpine amp for the JL subs by running one pair of stock sub leads to the amp input. I did nothing to the other three pairs. So far no problems, subs work well.
Good luck with yours...
mr_bock said:The stock M Sound subs are dual voice coil. There are a total of four pair of out output lines from the amp. I looked at the left side outputs and used a VOM to compair each pair while powered ( not sure if one pair is used for NAV/Phone?). I tied off all unused outputs (insulated) and connected the one pair to the Alpine input which has the output bridged to the pair of new subs. I don't know if the outputs not used would cause any problems..... only time will tell. Maybe someone knows the answer?
Best of Luck! :cheers:
