guys i really need your help
i have the following:
sr6500 up front
pdx-4 100 amp
pdx-1 600 amp
Alpine 7887 radio
when i first start the car, i get a discharge noise from the front driver speaker, sounds like power discharging, last about 2 mins then goes away, some times when i put the music up then turn it down the noise comes on then goes away after 2 seconds
i have my amps grounded to my cap, is it possible its that? i returned the pdx 4-100 three times, all three amps made this noise, what the heck could it be?
Yup, there is a good chance its your ground. Ground your amps to the chassis.
everything is grounded to the chassis...still have the same exact noise
you need to check and make sure none of your RCAs and speakers wires are pinched/cut.
yea i thought of that..but wouldnt it make the noise all the time if it were that? not jsut the first 1-3 mins the car starts up?
Didnt catch that. Sounds like a faulty radio/amp.
well i replaced the speaker wire, and changed the rcas, and replaced the headunit...same noise....the amps been changed 4 times...should i try a different amp? all ive done is change from pdx to pdx...
maybe i have bad polks up front? any one have issues with the sr6500?
Man, stuff like that is near impossible to diagnose over the internet. Even though its grounded to the chassis, you might want to move it somewhere else.
