hi guys . i just put an alpine cd in my 93 sts. it works fine and its 4 channels are wired directly to the speakers, i am not using the stock bose amps. when there is a heavy bass note the deck cuts out and the lights of the deck dim. i had the same problem when i put a deck in my 86 seville. i would like to correct the problem before i add subs and an amp this weekend. at low and moderate volumes the deck sounds fine. I am still using the stock bose speakers. thanks in advance guys.
