qx4 bose replacement

[bubbajack]

ok I'm ripping it all out. I know the qx4 has two amplifiers. My question is: I'm going to have to wire each door speaker to my new amplifiers seperatly or can i use the existing wires with a harness. this is tricky because any wire running from the head unit must pass through the amp first... right?

You can run with a new HU and the old amps, but that means you're using the old amps, and most people don't like to do that.

You can just "jumper around the amps", but the wiring is anemic and it should really be upgraded to a heavier gauge.

The better way (repalcing and running new wires) is alot of work, but most anything worth doing is .

Good luck.
