Question about JBL GT150 Car Subwoofer
Basically i got a amp and a sub the other day and fitted it in my car. everything was working, but i notcied little sparks from the wires at the back of the amp (when you moved it abotu) because it would sometimes touch each other (the red wire and the black wire) the subwoofer used to go out randomly sometimes and come back. anyway today the subwoofer stopped working altogether but theres still power in the amp because the green light comes on which means the amps ON, but still nothing comes from the sub. I checked all the wiring and it looks correct. from grouding, to remote cable... everything seems in order. anyone know whats wrong?
If you have real old wires from the amp to the sub try getting new wires on it. check the little wires that go to the cone itself on the sub. sometimes they can manage to get pulled out of their terminals and make sure that thier touching the terminals on the correct spot

I have a amp that has the green light on so I know the amp is good. I took the speaker out the box and hooked it up to the wiring for my 6-9's so I know my speaker is not blown but when I run it to the amp it kinda ketone little bump of bass out and then nothing else.why?

For most of you your red light should be green on newer amps it only turns red when the amp is not pulling enough power or is over loaded and you should always disconnect the ground wire of the battery before wiring up amp me on the other hand my amp is working fine because i tested it with other speakers however my 12 inch sony explode has no sound is not busted and terminals are not loose or broken.... solve that one?

Same thing happend to me when i wired mine. I didnt disconnect the negative battery terminal and touched a ground(metal parts of the car) with the positive cable. Blew my fuse in half. Best buy carries replacement fuses so check it out

When you indicate that the red and wires on the amp were touching at on time these are most likely the positive and ground leads from the battery and chassis (respectively). If that is truly the case, check the fuse on the positive lead going to the battery or that which is on the amp to see if it is blown. When this fuse is blown, it would not be uncommon for the power indicator for the amp to still come on if the radio is turned on. I think tis is more than likely the cause of your problem.

I had a similar problem....what happened is that the amp send the charge of the sparks thru the speaker, so try wiggling the wires that go into the cone of the sub... it will work, but i dont think the problem can be fixed

SOURCE: wiring on back of head unit
You don't need to change the cables from the head unit on. Just strip of the end of the wires where the old speakers are and crimp on the proper connectors to connect them. Alternatively you can just solder the wires directly to the speakers. I always **** splice at least 6" of wires onto the end so you have more wire to work. The only reason you would change the wires would be because you are putting more than 200 watts per channel. You didn't speak of an amp so no worries.

Those 12's Need to be in a Ported Inclosure to release the Air that the Bass Produces. Use a 1 Inch Key Hole Bit and make 1 Hole at the Top Corner of Each Portion of the Box. Top Left and Top Right. Please Rate My Response! Thanks!
