You are overloading the factory speakers.
Yes and yes
The amplifiers are on the infinity speakers. Each speaker has its own amp.
The 1997 Grand Caravan Infinity amp can be located behind the stereo system. The stereo system will need to be removed in order to access the amp.
Infinity speakers
For the best rated brands of car stereo speakers, Kenwood, Sony, Infinity, and Rockford Fosgate are among the highest rated. The prices are also reasonable.
Amplifiers are on the speakers in the door. Otherwise its just in the am/fm/stereo unit
The 'fader' setting on the stereo may be set to 'rear'. The front speaker wires may be damaged or disconnected from the stereo or speaker.
To hook up stereo speakers in a truck, attach the stereo wiring to the stereo and run it to the speakers. Clip the stereo speakers into the wires and place them in the panel spaces in the truck.
Dont understand your question because stereo speakers are normal speakers
There is an amp only if equiped with factory infinity stereo with 7 speakers. If so, the amp is behind the glovebox.
Yes, the speakers (150W) can handle more power than the stereo (140W) can produce. If it were the other way around (stereo more powerful than speakers), that's when you burn out your speakers.
depends on if its your CD/casset player, or it could be your speakers that are blown try putting a aftermarket CD player in with a wiring kit if that doesn't work replace the speakers but check your fuse first
