Question about Alpine CDA-7832
SOURCE: Alpine cd redeiver CDA 7837
Just a guess, I’d say who ever installed it didn’t hook up the connector behind it. But lets say they did. In most cases, the radio’s connector bundle will have a fuse. It’s a good idea to check your car’s fusebox first to see if any fuses are blown there. In either case, if you replace a blown fuse with "the right value", and it blows again, have a tech check it out. Note that if you try to get to the rear of the unit, do a little research into how the radio is accessed through the dashboard. Most car radios aren’t quickies to get at and some folks can do damage trying to get at it, but if you methodically take logical steps, you should be able to pull the radio, check the connectors, locate the fuse if it has one. Of course, there may be a wiring incompatibility, meaning, the OEM radio had it’s own specific wiring harness, the Alpine was installed, but someone didn’t get the adapter harness to fit the car. Who knows. Good luck. TekTrax

this is very easy...just unplug the rca cables out of the back of the deck, and plug them into the "subwoofer" output. On some alpine decks this is on a "pigtail" wire that extends from the deck. Once this is connected to the right output, you can control the subwoofer level from the volume knob by pressing it inwards.
Also.... your amplifier should have a low pass filter, it should be on a switch marked "LPF". Make sure this is switched on.

Your amp is not turning on - what you should do is connect the "blue/white - remote turn-on lead" to whatever wire you have the "blue - power antenna" output from the Alpine connected to now. That should solve your problem.

Does it play the tuner but not the CD?
If it so, the problem is directly related to the CD deck. If not, the problem could be a sensor or any number of other components that may have overheated.
Try to reset the unit. Most of the time this error is an electrical problem not fixable by the end user. But it is worth trying to reset the microprocessor and see if that helps.
Here is a diagram of where the reset button is at. Press it in with the tip of an ink pen or paperclick, whatever you have that will fit into the little hole. Just hold it in a couple of seconds. Be advised that when yo reset the unit, you will loose all things in memory like the correct time, preset radio stations ect.
If this does not help you will need to have it checked out by a good repair center. These Alpine radios are very good radios and are worth getting fixed unless the estimate is close to what you paid for it.
good luck, I hope this helps. if so, a good rating would really be appreciated. You can always ask me for more help if you need it. I have been repairing car and home audio equipment for over 17 years.

actually, chrysler/dodge has factory Infinity sound systems installed. The nice part about these systems is that you dont have to bypass the amplifiers in order to put a new radio in, but simply power up the amp by hooking up the amp turn on wire at the harness. The alpine should have 2 blue wires coming off of the back, one that is solid, the other with a white stripe. The one that is solid only has 12v when the fm/am radio is on (used for power antenna) but cuts off when other sources are used (cd,aux,ipod). My guesses are, you have the amp wire on the vehicle harness (blue) tied into this wire, instead of the BLUE/WHITE wire on the alpine which has 12v as long as the radio is on. i hope this solves your problem, 9 times out of 10 on a chrysler this is it.
