Yeah, I will do a full rewire job. Wanted to avoid it due to the amount of work it takes, but if the wiring in the Z really is just that bad, I'll just do it.

Anything else I should be aware of when going the route of clipping the wires before the BOSE amp and doing a full rewire / rebuild from there?

BTW: In car audio, I don't subscribe to the "buy 300$ cable" team. I've done more than enough testing of cables in a controlled studio / anechoic chamber enviroment to know that in a car where noise levels are insane to say the least, especially in the case of the Z, apart from adequate shielding and load handling capability, the wire you use har very little impact on the perceived sound. This of course when using somewhat reasonable quality wire, instead of the cheapest radioshack wire.

But oh well, there are those people too who buy 300$ HDMI and other digital signal cables, who believe it will somehow keep their ones and zeros in better shape. :P
