Tapping into Factory Wiring

[KoalaZ 10+ year member]

I have a 2000 Jeep Grand Cherokee, with the Infinity amp in the back.

I'm upgrading everything but the head unit this weekend, taking out the amp and adding a new one for the door and dash speakers.

Since I'm not getting a replacement head unit until I fabricate a double din dash, can I tap into the high level (?) wires coming out of the head unit, feeding the factory infinity amp? In other words, can I run my amp's speaker level input signal off of the front speaker wires going from head unit ---> factory infinity amp, and then remove the infinity?

Or should I buy an LOC? Trying to avoid this, it'll only be a few weeks until I get a new one.

if your amp has that option, then yes it should work.

the signal coming out of the hu into the amp is low level. from amp to speakers is high level. in my car, i just tapped into the low level wires coming out of the hu with rca terminals, disconnected the harness to the amp, works fine.
