Infinity Sound System ?

[black03montero]

Got a question that may be dumb but who cares, I need some help on this one.

A friend of mine has asked me to install his amp into his 03 Montero with the Infinity stereo system. Now I have installed many stereo systems in cars but never just an amp to a factory system. I pulled out the radio and ,of course, no RCA jacks to run from the stereo to the amp. I did see a simple harness that basically just ran power to the radio. Then I saw the factory cd changer cable that went no where as he does not have the changer. Then I saw another cable similar to the changer cable & realized that this must run back to a factory amp. Sure enough, I traced it back and found the amp behind the interior panels on the passenger side.

Question is, can I install another amp to run to a couple of subs on this factory setup and if so, how?

Thanks in advance for your help.

Hey Black03montero,

Here is a link to a part you can buy to change the amp.

Like Frehley said you need two wiring harnesses one for the head unit wiring and one for the Infinity ammp. The adapter gives you two set of low voltage RCA inputs. FWIW- the amp on my 02 XLS w/touring package was located in the rear passenger side wall of the cargo area inside a pocket in the sheetmetal.
