hi,
my friends has a 97 firebird formula,it has the moonsoon sound system,with the amp and all that,he wants to put in his polk momo's 6.5 in. in the rear seat section,however his polks are single voice coil,and the speakers in there are dual voice coils,so how would he wire these in,to run off the factory amp?or should we delete factory amo,and install another amp?thanks for your time.
