which door speakers? The woofers or tweeters? if the tweeters then sounds like the amp in the deck is bad. If the woofers I dont know. Might be a plug or a fuse having a problem.
True blue is going the right way. Under the rear shelf are two amps. One for rear 6x8s one for the fronts. The 2.5" front and rears run off the decks internal amp. If the rear 6x8 speakers are working but not the fronts than eaither 1. the amp burnt out. 2. The plug going into it came out/loose. 3. The plug on the back of the stereo is loose. Theirs a seperate plug for highs/lows and have been known on earlier ones to vibrate loose.
If both front and rear are not working then you blew a fuse or the plug on the deck is loose.
Well start with the audio fuses. Thats prolly not it cause im pretty sure the front and rear amps share a fuse Then id go under the rear shelf and with the system on jiggle the connectors on the amps and see if they are loose. If thats not it you need to bust out the multi meter and see if you are getting power to the amp and remote on signal. If they are both present than the amp went out. If the amp went out PM me cause I got a couple in mine I can yank since I bypassed them
The amp that run the front door speakers went out in my 99.....
but not totally, it sounded distorted like the speakers were blown. I was about
to replace the speakers until someone said check the amp first.
