    Default Sub sound only, no speaker sound :(

    hello, i just finished installing my 10" polk momo sub in my truck. I wired it using a stinger amp wiring kit and ran the wires correctly as far as i can tell. when all was said and done, I have sound(bass) coming ONLY from my subwoofer and no longer have sound coming from my speakers. I have no clue as to what could cause this, any suggestions? thanks,

    chris

    Are your other speakers running off your HU, or an amp? Check your RCA connectors. Did you accidently unplug your other speakers' rca's and use them for the sub?

    hey polkthug,

    rca's for speakers are intact, never touched 'em. running two front 5 1/2 speakers off of my head unit. subwoofer hooked to amp to 4volt preout. also tried to hook different speaker up to see if it would work but no luck, no power at all to speakers it seems. getting only bass sound from sub, it's not acting as a speaker. still baffled,

    I think you should confirm that there's no sound from your head unit, sound strange that the internal amp is not working the front 5 1/4" speakers.

    First with power off, remove the signal to sub amp to see if the fronts are not just being over powered by the sub (masking the front 5 1/4"s)

    Still nothing check all settings in the radio, and or all power to radio head.

    thanks for the suggestions guys,

    all connections are good and the deck settings are fine. the only thing i can think of is that something internal in the deck is fried. i'm gonna drive to a buds and try another deck with it to see if it works, if so looks like i'll be out the price of a new head unit :(. let ya know if it works.,

    to add even more mystery,

    there is power to the speakers! speakers aren't processing wat's given to them and turning it into sound, gotta date in a couple hours to get a pro to look at it, we'll see if it was worth the cash.,

    Probably a wire touching something it shouldn't. Let us know how it turns out.

    Ok, I'm thinking that your stereo is bi-amp'd output so the negative wire and the positive wire floats above ground.

    So if you connected the Sub amp to the speaker output of the radio then this is your problem, but if you did this I think it fried your amp chip up. Seen this to many times before when grounding the neg side of the speaker output.

    If you hooked up your sub amp via RCA outputs then I not sure what’s wrong with you radio. You stated that the speakers have power but no sound, power do you mean the speaker is pushed out or pulled in? If so the output chip is fried, must have grounded the speaker somehow.

    The radio can be fixed but it may cost like $65-95.00 so a new radio maybe better then repairing your radio.

    He said he took it back to the store and they hooked it up and it worked fine...so doubtful any damage was done...

    okay just got back from the installers and the guy only had an hour. i stated that the rear speakers were not connected and as it turns out that was the problem, the leads to the rear speakers were hanging loose and were grounding out. great so now the speakers work.. BUT, dumb ass did something and now i gotta figure out why my speakers are working my but my sub isn't working, i'm thinking just a loose remote wire problem but it will be dealt with. let ya know when all is going wel. Thanks to all for suggestions and support as I did try every suggestion. thanks,

    chris
