Installed a new deck couple days ago ( panasonic cq-8803u) and when i start my car my speakers make a loud pop. then thats it. If i play a cd in my deck all my speakers work great. No problems at all. But when i play the radio i only get bad quality sound out of one speaker. My speakers should be wired correctly since the cd's play nice. I'm not sure wat the problem could be coming from. Antenna connection is good. could there be a short somewhere since i get the popping? actually the pop happens as soon as the head unit is powered up. Any ideas?

Sounds like u may have a loose or poorly connected speaker wire.. some times installers use electrical tape witch can come off or cause issues..I would check all speakers independently withe the balance and fade options on the deck, then find the ones affected and then check wiring to them , if all wiring connections are good, then u may have blown a speaker.. if you had brand new speakers install you could have blown the voice coil by amplifying the volume too loud too fast...
Most speakers have a Break-in Point.. meaning not to put speakers at max volume for the first few days..
It may be getting hot because the amp is shorted out. If you have a bad speaker or one that is grounded, you won't have any sound. Disconnect all the speakers and connect them back one at a time. If the first one doesn't work, disconnect and start with a different one. If none of them work is is in the stereo. If any work, i would check the ones that didn't to see if they are bad or grounded out. Please Rate!
what model kenwood speakers do you have? what head unit do you have? do you know how they hooked up the rca cables to the back of the deck? if this deck has got 3 pre outs you may have lost the sub pre-out. are you amp lights coming on? if you are still having problems you can take a 9v drill battery or bigger and touch the wires from the speaker to the battery, make sure positive to positive and neg. to neg. the speakers should pop if they are ok, that should re-assure you on the speakers. let me know and ill help where i can. good luck
My apologies, missed the connection. Now I remember, must be really getting old.
Back to your concern, which fuse pls? the 15 amps for the Panasonic or the amp"s fuse.
Incidentally, even if the speaker wires were wired incorrectly, that would not cause the fuse to blow. The only way the fuse would blow is if the unit was connected with the polarity reversed, even just once. Internally, most units have a reverse protection diode and/or regulator that would short circuit itself. Thereafter even if it were wired correctly to the battery, the fuse will always blow.
you have wires grounding out at the back of the unit. i suggest trying to completely rewire it and see how that works. its easy if youve never done an install so dont sweat it. email me if you have any questions. [email protected]
Need to Know what shuts off. Power or audio just Shuts off.
If Power is cutting off try disconnecting all speakers see if it stays on. If it does connect 1 speaker at a time if you hear a pop when connecting any of the speakers or when fist turning on you probably have on side of speakers grounded (common ground) this radio is not designed to have any speaker be grounded since each speaker wire is at a 6v potential. Do all speakers produce proper sound when stereo is working if not whatever speaker isnt may be defectve. Just a couple of many possibilities. [email protected]
You may have one of this two problems:
One of the speaker wires is grounded to the chassis.
Or your car may have a factory amplifier between the radio and the speakers.
My suggestion is to rewire the speakers lines
Your Sub box gets its signal from the PReamp output. This means your problem stems from the CQ-C9700U amplifier section. You may need service from Panasonic on this one, or a new Head unit. I cannot think of any adjustment that you can do to eliminate a skip sound.
