Because of the amplified 1 ohm speakers a Bose setup uses. If you search the archives (or search on Google "repair Bose"), there are places that specialize in fixing Bose systems, so repairing it will remain an option even though your local dealers could not deal with it. Personally, I am no Bose fan, however, if it it was ok for you while it was still working, having the headunit fixed may be the solution path of the least resistance.

If you do replace the head unit, but want to drive the Bose speakers, you will need an electronic adapter. The most versatile one, plus one that has great construction quality, and multiple ground connections to avoid ground loops is the Power Driver (http://www.linkmeup.com). This unit will allow your aftermarket head unit to drive Bose amplified speakers, or will let your Bose unit drive aftermarket amps. I used a 2 channel unit with great success for years (until my headunit died).

If your budget allows you to replace everything, I strongly suggest you replace the speaker wires leading to all 4 corners.

You can splice into the existing harness, but this is the down side: The Bose signal is closer to an RCA signal than a speaker signal. As a result, the wires in the signal circuit are very thin and shielded. The two power wires are thick, but they would be tricky to fully disconnect and isolate them from 12 Volt and ground respectively. It can be done, but you will have to find them, and properly "intercept" them.

Whichever road you take, good luck,

John
