It is really not that much more work to wire to the speakers. There are four channels only so you just need to run 4 pairs of wires to the trunk and tie in to all 4 at the amplifier outputs. This is the best way to do it so you can have a reliable system without having the old amps still hooked up. If you didn't have to already run the antenna coax to the rear I would understand you noot wanting to do all that work but it is the best long term reilable way to do it.
