Eugene S: Hey, my CD player doesnt work, when i put a CD in it just says CDERR, what
do you think might be the problem?
Ben Corcoran: same process for the concert series...i have a 2005 S4and want to replace
the deck and door speakers, but i want to keep the factory amp...any
AutoToys: The Laser in the unit and mechanism may just need an alignment, or there
may be more serious problems.
AutoToys: @teamplanetaudioben I would take apart the door speakers, or one of the
speakers, just the wiring to the car, take a digital multimeter, put it on
resistance setting. See how many ohms the factory speakers are, if it is 4
ohms, you can replace it with any aftermarket speaker, however, if it is
anything different, your factory amp may run hot depending what the load is
on the original speakers
