Aftermarket amp/speakers w/o LOC?? Non-Bose

[adrhld]

Anybody ever hook up an aftermarket system (amps, speakers, sub) to a factory head unit WITHOUT LOC's? Correct me if I'm wrong, but if you use an LOC, you are converting a signal that has traveled through the factory amp. Wouldn't a low-level signal right from the HU, before the factory amp, be best? Any diagrams available? Or wiring harnesses? I have a 2000 Tahoe, non-bose as far as I know, with sub.

A loc takes (2) sets of speaker wire and converts them into a rca input, so you would have to give up, like the pos rear 3.5's all the way in the back, then hook those speaker wires into the LOC and then you can hook up your amp's rca's to the loc

still need a LOC, then to your new amp.

iv never heard of a person doing such a thing....
Iv used loc's before n previous vehicles, my guess is that there is a really good reason why there is such a thing
