Adding aftermarket audio to factory amp.

It sounds like you removed the remote wire from the factory amp to run your aftermarket amp. You need to reconnect it, and if necessary, split it to go to both.

It depends on whether you have the standard audio system or a premium sound system. The standard system has no factory amplifier, the premium system has a factory amp and some other gimmicks that are hard to interface with. A proper OEM amplifier upgrade will require changing the factory speakers with stronger replacements, as well as adapting the factory head unit output to a signal your new amplifier will like. More often than not, it is more economical and better sounding to just change the factory speakers and run the replacements off your factory system. To drastically improve the sound system, it is more effective to just change everything.

factory amp? So you have an aftermarket amp, a "factory" amp, an aftermarket head unit and subs? Adapter???

what radio? factory, aftermarket, etc? if its factory just go to a wrecker for another one, yours is non-repairable. Aftermarket is a problem for a stereo guy.

UNFORTUNATLEY, DODGE/CHRYSLER ARE NOTORIOUS FOR HAVING COMPUTER GLITCHES. RECOMMEND TO HAVE PROFESSIONALLY LOOKED AT

This generation of Vibe may have the upgraded audio system installed from the factory. In order to get the audio from an aftermarket radio to play through the factory amp, the factory remote turn-on lead must be located. If you are using an adapter harness, it may have the wire installed, just attach the blue/white stripe wire from the Alpine to the blue or blue/white stripe wire on the aftermarket harness adapter.

Or maybe the recall on the fuel return line 2001 Dodge Stratus Recall Date: 10/27/2000 2001 Dodge Stratus Component: FUEL SYSTEM, GASOLINE:DELIVERY:HOSES, LINES/PIPING, AND FITTINGS Potential Units Affected: 13100

EGR Valves rarely go bad. the EGR solenoid is common though, you can get it aftermarket, thats ok. The valve bolts on, 2 bolts, the solenoid just has hoses and a small elec plug.

My suggestion is to go to your local audio shop and pickup a dash kit and wiring harness to hook up the din head unit. I actually wouldn't recommend putting in aftermarket speakers unless you don't plan on reselling or they are blown. You could hook a sub up by running your power wire to your amp like usual, hook your amp turn-on wire to an accessory wire and buy a "line level converter" you will tap into factory speaker wires with this and it will convert it to RCAs. You will only need to do this if you are using the factory head unit. Also, unless the aftermarket unit has features that you want that the factory one doesn't, I wouldn't bother with that either. Good luck. Let me know if you need any more help.

i have a similar problem with my stratus except mine is a 95'. I haven't fully figured the problem out but i have been told to check all of the grounded wires you have hooked to your car.
