hooking up an aftermarket radio to the original door speaker

[710]

This is probably a dumb question but
I am taking my radio out and putting another one (aftermarket) in.
Can I connect the “speakers out” from the new radio directly to the stock Bose door speaker wires (so my amplified signal from the new radio will be going into the old signal wires on the door amplifiers)?

Or will that blow out the stock Bose door amplifiers/speakers?
Thanks

I'm guessing it won't be a good idea. You could either bypass the amps the door speakers (maybe), or I think there are such things as attenuators which will reduce the speaker out back down to line level.

If you're putting a decent stereo in, surely it would have a line out?

Hi Kevin,
I have 3 RCA line-outs but I get no sound from the (stock Bose) speakers when I connect them.
I connected the stock Bose radio back up and the stock Bose door speakers work fine.
I connected the normal wires up to some regular speakers and I get sound.
So maybe the radio is broken. Or something. I'll find another radio to test.
Thanks for your help.

Are you still applying power to the BOSE amps when running them from your new radio?

Yup.
