Subject: Speaker Replacement 7speaker 9-3 2005


Hi, I have the 7 speaker system with factory stereo. Obviously the speakers could be much better, so I'm considering replacing them with aftermarkets. I know I have 4" speakers up front and 5.5-6.5" in the front doors with 4" in the rear. My concern is that they would be under-powered, making them worthless without an amp. Stage 1: Replace front and dash, for much better highs. Easy transition. Stage 2: Add new amp to rear, and add 6x9"s into open ports in rear. I read: http://members.iinet.net.au/%7Emmo/Docs/saba_pdf.pdf for step by step instructions. It seems reasonable. I don't see why it wouldn't work. Taking the signal for the 1 set of rear speakers and boosting it so it powers 2 sets. My concern is it overpowering the front speakers. I'm also not sure why he didn't just run wires from the factory amp under the passenger seat to the trunk, and then adding the line converter for the amp. Speaker wire is much more concealable than RCA's. Stage 3: Option 1: Replace the factory amp (is it possible to do this) Option 2: Use a 6 channel amp in stage 2 for all speakers Option 3: Add a 2nd 4 channel amp to power both sets of front speakers. My concern with Options 1 and 2 are having to run speaker wires back to all the speakers, or maybe I could just run speaker wires from the new amp to the old amp, and then jump into the factory wiring there. Does anyone see any issues, or can you make any reccomendations?
