Audio Systems: infinity system in 98 grand caravan keeps cutting out, dodge grand caravan, infinity system

Question
i have a 98 dodge grand caravan, when i bought the van the original head untit was gone. i put in an aftermarket cd player, subs, and amp. when i turn the volume up and put any kind of bass to the speakers they cut out (the infinity ones) any suggestions on whats wrong?

Answer
Yes bad radio installation, the infinity amplifier is made to work with the  2 wattas factory radio. now you are not usng that, the radio you have is a high power 40 watts x4

3 ways to fix this problem
1 install the factory radio
2 remove all the speakers and factory amplifiers you have 4
3 or install this after the new radio
