Audio Troubleshooting PLEASE HELP!!

[bwjohnson88]

okay, help would be greatly appreciated because I've been asking so many people for help and nobody seems to know the answer. I am a bit of an audio newbie so please excuse my lack of knowledge.

Okay, so I have a 2001 jeep wrangler and I installed a cheap custom audio system in my car 2 years ago. Kenwood 50x4w sterio head, 2x 5 1/4" sony tweeters on the speaker bar on the top of the car, and 2 sony speakers for in the dash. Along with that, an MTX 10" $100 sub and a dub audio 550w mosfet 2 channel amp. So my problem is that only my sub is giving off sound. I get no sound out of the speakers. This just happened one day when I turned on my car. Everything was working wonderfully for about a year then one day the speakers just didnt work. Sometimes when I hit a bump in the road you can hear them click in for .5 of a second, which lead me to believe that it was a loose connection. Well I checked all of the wiring and nothing is loose and everything is fine. The fuses arent the problem, there is nothing wrong with the amp and all my speakers are fine, no blown speakers. If i unplug the sub, i get no sound at all. So basically, only my sub works in my car and it sounds like crap. Please help!!!

sounds like the internal amp in the CD player is bad. You can always get a cheap 4 channel amp to run the other speakers

yea, you gotta think it's something common to all the speakers running off of the head...
also, because you said you can hear it cut on when you hit a bump, recheck your connections...
if it's pulled hard enough, the metal conductor inside a wire can break, while the rubber insulation just stretches...
I would "very carefully" wiggle the length of each wire while the h/u is playing looking for the bad cable/wire...

hmm, okay, I will check each of these out and give an update asap. thanks guys!

Yes the internal amp was blown. Thank you so much. I bought a new radio, but now my front speakers wont work. When i turn on the radio the two front speakers that are in the dash buzz really loud and then nothing. Any ideas??

I can't imagine that being a grounding problem.... You might try checking the wires & making sure they're connections are not hitting bare metal somewhere.... Or, the other suggestion is that you could have a defective head unit.... If you've got another head unit lying around.... Use it to see if it's the wiring or your new main head unit... Can't hurt to take a little time to do that if all's harnessed together! Defects are rare, but they do make it out of the factory. Is your rear speakers clear? Or, are there "other sounds" other than the intended audio? like buzzing sounds?

Sounds like a ground problem. first things first did you solder your connections (you should) next look at the radio
yellow goes to battery
red goes to old radio on wire or something that is hot only when jeep is on
black goes to a bare groung. with a good connector on the end. no bare wire
Rca jacks to the amp along with aux wire
good 8 gauge wire for your power from battery
Also check to see if there is any kind of factory amp from radio to speakers. (don't think so) this has been a problem I've seen with other cars. Take your meter and locate each speaker wire to the speaker. If your not sure put it on ohms and touch you black and red probes together. it should read 0. Next put one wire at speaker to different wires at radio. if you trace the wire and nothing is in the way. test the speaker it should measer 8 ohms I think. anyway keep tryin it's always something stupid.

Would it be a bad idea to suggest to connect the rear speakers to the front channel , and if the rears work, sounds like the HU or the front speakers might be damaged. Oh, and what they said.
