Hi all.
I have an 03 alero with a good enough factory system for me, except the bass.

I have a Rockford 10" sub in a box, with a GMH100 amp attached for the trunk.

How do I get the signal to the amp(no pre outs) and keep the factory signal to the rears?

Must I wire a mixed mono for this?

Thanks

you can splice into the rear speaker wires and hook up a line-out converter (LOC).

look for them on:
www.partsexpress.com

or, if the amp has high-level inputs...you could just run speaker wire from where you spliced into the reaer speakers to te high-level input on the amp.

So a parallel output for the rear 2 channels into the amp should not affect the head unit?
That sounds reasonable, if the amp does high level.
If not an LOC will give me no reart speaker output. Then I go the mixed mono route?

Thanks Marshall
