I have an 02 Sable LS Premium with the Mach Audio system in it and I was wondering if there is a way to hook up a sub and amp into the stock deck or do I need to put a new one in? Thanks!

 

I'm not an audio engineer by any means but I would imagine if you tied an amp into the stock stereo system it might blow the speakers to bits. On the other hand, if you installed a sub woofer into the factory system it might not have enough power for you to get any real "boomin" bass.

 

now if you have an amp with a "speaker input" that will take the kind of output that the rear speakers get from the mach system (they're amplified if I remember correctly), then you can tie into that speaker output and add an amp to drive the sub and put whatever you want in there. The amp would have to be wired up separately of course. now finding a remote line from the factory deck may prove difficult and may just be easier to use a switch for it connected to a line that comes on with the accessories. if you pull the stock deck out and look at the rear of it does it have any RCA stereo out ports? if it does, you can use that for sub output. if not, you'll have to run off speaker lines and have an amp that will accept speaker level input. I generally go totally aftermarket if I'm going to modify the factory setup at all.
