Contour Enthusiasts Group Archives Forums Modifications Audio EXTERNAL AMP

im trying to run my interiors with my amp which is in the trunk, but theres no sound(problem).i have all the speaker cables and the RCA's running to the amp. I set my line in switch on the HU which is for external amps and my stock ones work when i set the line out switch for an internal amp no speakers work, i have my new ones with all the connections in the front and stock in back.is there a factory amp in my car?wiil that effect it?i have a 98 csvt.

This may sounds silly but did you run speaker wire from the amp to each speaker?

yes there is a factory amp.
it's located behind the glovebox.
if you go to any audio shop the should
have an amp bypass harness that can be
sacraficed to make the wireing really
easy. much easier than running wires
to every speaker

yessss, ive done this before, just not with these components.i even ran the speakers directly from the amp, cause im running them through the crossover, and no go, so its either the HU or the AMP not giving the signal.

So im thinking i have to disconnect the factory one, its causing an interference.

Teh factory amp needs to be bypassed.
It can't accept the input voltage from
your other amp. Go to a good audio shop
and tell them you have a ford premium sound
package and that you need th amp bypass
harness. It hook the input into the factory
amp to the output to the speakers. That way
you use the wires behind your HU and it goes
to your speakers.

I had a similar problem. Come to find out it was the turn on signal from the factory radio to the factory amp. The signal was not strong enough to turn on my Presion Power amp and the factory amp at the sametime. To solve the problem I used the antenna signal to turn on the amp instead of the factory amp turn on signal
