everytime i press the brake the back speakers cut out.. :P
Check the connectors in the rear area. They are known for getting hot and melting causing a bad connection. Check the radio ground, and the grounds at the rear of the car. You will have to remove a few panels.

After he described that, I had him look around under the hood just on a hunch. Sounds like his truck had an engine fire with a previous owner,
My sister's 2005 Altima SE-R 5sp Automatic had some transmission issues and I think some would be interested. The transmission would intermittently stay in 5th gear, the PCM would record a U1000 code for loss of CAN communications with a module. The shift indicator would either go blank or show only 5th gear in manual mode. The trans would make some loud whining noises and the solenoids would randomly engage. The problem was the TCM engage relay. It was only allowing 7vdc across the contacts. It is mounted right next to the TCM which is behind the glove box to the right of the PCM. The TCM grounds this relay after it receives batt and ign power. This is the power relay for the solenoid drivers in the TCM. New relay fixed the problems.
Heard that, as soon as she described to me on the phone I knew it was a power or ground issue. First she called and said my trans is shifting funny like a bad miss in a way. then she called and said she hears a buzzing under the dash(relay). Then she called with buzzing coming from the tranny.
Yeah, it would not have been long before damage occurred. There may be damage to the tranny not showing up yet. Pressures were being directed to all the wrong places in transmission. I am surprised the TCM did not smoke with such low voltage across the drivers, damn good protection circuit in the TCM. I would be interested in knowing what type drivers are used for the solenoids, they are better than GM's that's for sure.
Usually the drivers used will take much more current than they have to. Undervoltage is unlikely to hurt the electronics. Assuming Altima is Toyota, Nippon Denso electronics are very good, like most Ford electronics. GM and Chrysler = puke.
