Often they more advanced systems, complex wiring, factory amplifiers, and other features that can make installing aftermarket component difficult.

Why did you choose this?
Sonic Electronix Store
According to the installation technicians; this unit is fully compatible with the infinity-stock amplifier that comes with my 2000 Jeep Grand Cherokee Limited.

Will this work for 97 dodge ram 2500 with factory infinity system m? 97 bit older was not sure. Last time I tried to hook up aftermarket stereo without interface had poor / low sound from speakers.. They did not all work even with aftermarket wire harness.

Best Answer: Hello,

Unfortunately this will Not adapt to your vehicle. The amp integration harness - for an aftermarket headunit - is the Metra 70-1818. The Metra 70-1818 will take the LOW LEVEL RCA Signal and send it to the OEM Amplifier. This might cause Low Volume. The common 'work-around' is to use the High Level speaker wires instead.

Does this work for a 1997 Jeep Grand Cherokee? If not, could you please advise to what would work.

Best Answer: Hello Kim,

Unfortunately it will Not work & there isn't such a solution for your vehicle. A Traditional LOC (Line Out Converter) is you best approach.
