    My DE545 started to cut the rear channel and sometimes the center channel too. It certainly is not due to heat. The problem started few months back and then went away for a long time. Now, it is back and the click sound happens just after few minutes of playing. The amp is in a well ventilated location. I am going to take it apart and clean as described in other threads.

Took apart the boards and resoldered the Blue Relays. Now it seems to be ok. It looks like due to bad solder, the relay trips when the board warms up. Taking apart was relatively easy, several pluggable connections and many screws to deal with. I took a digital picture before pulling apart, so as to remember the connections. Also, had to remove the smaller boards to get to the big board at the bottom. The challenge is to solder, must be extremely careful to not drop solder on the board.

98 Durango Rear Speakers not working

look under back seat for preamp

Instead of resetting rear speakers each time.....

I have found a similar problem with the rear speakers on this unit (needing to be reset each time the unit was turned off), but found a quicker way around it.....with both the main unit off and the rear receiver off: turn on the rear speaker receiver, then the main unit. If the blue light on the rear receiver does not come on, turn off the main unit, and turn it back on again. This has worked for me ~50 times or so and has worked repeatedly. It's faster than going through the reset phase each time. Also when turning off the system, turn off the main unit first, and then the rear receiver. Sometimes I also simply leave the rear receiver on since it pulls only 4 Watts. Hope this helps any users.....(it also works on my boyfriends older generation model).

I can't get surround sound from my theatre system

Read your manual , there is a level setting for each channel as well as a test function. Also remember most media on pro-logic mode dont have to loud sound from the rear speakers. Only a forced mono mode may give you louder sound at the rear. Regards PSP

Volume fade

Check to be sure there are no speaker wires touching ground, and that the wires are connected in phase to the head unit.
Front Speakers 5 1/4" Doors Left Front (+) Green Left Front (-) Black/White Right Front (+) White/Red Right Front (-) Black/White Rear Speakers 6" x 9" Rear Deck Left Rear (+) Pink/Red Left Rear (-) Pink/Blue Right Rear (+) Pink/Light Blue Right Rear (-) Green/Red

The symptoms you are relaying definately sound like an internal amplifier problem. It is fading in and out for a reason - usually due to heat.

Have you had the radio bench tested (seperate from the car) to eliminate the car as being the culprit?

Since the radio was run with damaged speakers originally, the output or amplifier power supply on the amplifier may be bad.

As an alternative to repairing, I would suggest investing in a small 2 channel amplifier to power the speakers.

The radios claim 50W per channel, but in reality give 12-15W RMS power.

A dedicated amplifier with built in crossovers and gain adjustments will prolong the life of your speakers and add to the tonal qualities of your new speakers. Instead of turning up the volume on the head Unit, and sending out a distorted signal that will blow your speakers, an amplifier will give more CLEAN power to them, so it will be louder at a lower volume setting.

This will bypass the internal amplifier on the radio, and send a Low Level signal ONLY thru a set of RCA cables.

Good Luck!!

Stereo problems

sounds like a speaker problem, but it could be the stereo itself. it could have a damaged circuit board. the only way to find is to test the speakers/head unit.
