Hi, i have just replaced the Chorus with a pioneer dab head unit ,also replaced the front speakers and all is working fine..The rear speakers are just dummy grills as they were a option on the cabriolet and i don't have a bose unit,however i am going to fit some rear speakers and just wanted some help on the rear speaker wiring..My pioneer HU as FR FL RR RL connections vis RCA and at the moment i just have FL FR connected ,now if i was to connect the RR RL rca would i be correct in saying that that would be a output to my rear speaker wires on the wiring loom and just be a case of wiring to the correct colours and if so would it be from the pioneers side of the loom or from the connects2 loom ..My rears are green and purple ..Thanks
