How to run amp from OEM Navi/ OEM Amp?

[subydude81 10+ year member]

OK my cars a 2006 acura tsx with built in Navi and I have stock comps in front, 6.5s in rear doors then 6x9 subs in rear deck. I'm keeping the factory Navi so how would I go about running an amp to the front comps and rear 6x9s.

I have a 5 channel Hifonics amp but not speaker level inputs. I know of LOCs but since the wiring from the Navi goes into the factory amp i'm not sure how I would get enough signal for 4 speakers.

I'd like to just bypass the factory amp and run the 5 channel to all speakers, I know rear door speakers don't need the amp but might as well since I upgraded those rear door speakers.

Find the wires sending signal from your HU to factory amp. Cut them off, and wire in a LOC. No more signal sending to factory amp, new RCA outputs for your new amp.

The factory harness is not labeled and they make no aftermarket harness which blows.

if i recall correctly that headunit has low level ie rca outputs to the factory amp. I would get a peripheral sven4 and use that to tap in and get ur signal before the amp
