subwoofer not working!

[randy'sho]

I am in the process of redoing my stock jbl system that the PO cut out! I found that the stock subwoofer was blown, so I cut the hole out and installed a 10" rockford fosgate that I had....I have everything working properly except for the sub....I have power to the sub amp, but nothing is coming out of the sub! any ideas for me! I know the sub is good so that is not the issue! But I am stumped!

 

[shoofff1]

is the stock speaker amp plugled into the sub amp. a wire goes from the speaker amp into the sub amp like a high levle input

 

[randy'sho]

yep....and I tested the hot wire to the sub amp and I have power, but no sub!

 

[shoofff1]

chech the wire going from the sub amp to the sub and make sure its not damaged

Well if the sub has power but no sound it makes me think its not getting signal from the amp or the Head Unit.

 

[randy'sho]

did that man! if I test the wires on the subwoofer should I be getting any power? I guess that is a dumb question!

sub doesn't have power but the amp does! does anyone know what color the sub wire is going into the headunit?

 

[shoofff1]

I think its a harness going into the stock head unit im not sure when I got my sho it didnt have headunit in it let me research and find out what the problem is

 

[randy'sho]

yeah the PO had a mess with the wires! some cut some new.....alpine head unit! I went back to the oem! I know that I have all the proper wires back together though!

 

[shoofff1]

crack open the amp and check the solder points for the wire coming out if there ok take a volt ohm meter and see whats coming out it could even be a bad capacator in the amp

Not off hand, Does the manual have a diagram for the JBL system?

Here I took some pics of mine its a 93 and might be different from yours.

Now the two black wires you see on the left side are going to the subwoofer.

thanks man, where does the wires that come from the little black box that sits between the two amps go? that is my only issue, the connectors don't mach up!

I remember when i bought my first SHO it did not have the jbl in it. I added it but did not use the black box that sits between the 2 amps.

For a guy thats 6' 5" tall it was a PITA to crawl in and get this one.

Hope it works out for you. Vnuk1sho, I feel your pain. Im 5'7" and it was not to pleasent taking the pics i did. I also have my sub box and new amp in the trunk that i did not want to take out.

 

[Vnuk1]

Yeah the nut that holds the trunk latch to the lid the left one fell off somewhere and now is a pain in the ars to open the trunk. Sorry Randy'Sho I did not get the top of the black thing for you, could not get a good angle on it.
