I wired the car and everything, grounded the wire right and sanded the paint, now when i turn up the volume at about 13 on my sub completly stops working ?????????

i have a JL 10W7 in an H.O. box and the AMP is a 500/1 series amp that is brand spanking new
the wires are JL and the fuse is too...... what the hek is going on>>>>>>>>>>>>
HELP please

 

check wires? is the amp going on protect thats why the sub stops? or is it just the sub?

 

it may b protect is what im thinking the sub operated just fine under other amps i tested with the sub and the two were woking yesterday in orderly fashion......now i got the AMp tucked under near the spear tire but i cut all the stroform and i think thats enough air???

 

what size power wire are you using?

what size fuse by the battery?

check those two first, i'd recommend 0 or 2 gauge, if not, no lower then 4 gauge for wires.....and i'd put an 80-140 amp fuse in

if those are ok, check your grounds and check to see if the connections are tight at the amp.

i'll have to think if there's anything else i could come up with...

 

did u get the problem resolved?

 

id check fuses and your gain setting.
also see if an RCA didnt come out,happend to me once.

 

checked everything, 4 gauge wires JL FUSE box AMP has power and the sub does too. Again it cuts off at higher volumes im getting it checked by a guy today because i have no idea whats going on......i've done many systems but this is my first JL audio 1..... thanks for the help yall and i hope i solve this............

 

if you are using 4 gauge wires for power that maybe your problem, the smallest id have would be 2 gauge, but 0 or 1 is recommended.

 

sorry... but I've gotta...

maybe you have a spinaltap amp - those only go to 11.

bells just started ringing when you said 13

 

4 ga on the 500/1 is great, the are very efficent amps no reason to run 0ga

 

you need to see if the amp is going into protect mode or cutting off.
if its going into protect mode your ground sucks or you have an rca or power turn on wire grounding out.
also check the wires that actually attach to the speakers as they may be loose or corroded.
also do you lights dim alot? i wouldnt think they would with that amp, its not that big. but in any case if they do your alternator could be dropping voltage too low. get a multimeter, put your leads on the amps input and ground, then have one of your friends crank it up. if it drops below 11 volts your amp is protecting itself and your probably losing your alternator.

 

its no going into protect because the red light is not turnig on and the only thing i can now think of at the time is the alternator that POLLUP was taking about ill give the volatage a check...............thanks for the comments

 

its not the alternator.............. i talked to a pro over the phone and he said the amp is defective and i just bouoght it brand new.............

 

I doubt its the amp cause i had the same problem awhile back. My problem was i wired the amp and sub wrong so it was cutting off cause i didnt buy a mono amp. I would make sure that you wired the amp for one sub though

 

Well...it hasn't been asked yet...

WHERE is the ground point?

 

hay i used your gutting a tc form

here are the pics and i dont know what is going on?????





the ground

 

this person had the same problems

ground point looks decent. now that someone else mentioned it, what ohms do you have the amp running at?

 

the JL amp is set to its own OHM configuration depenting on the sub so if it senses that the sub is 2 OHm the amp runs 2 OHm and it its 3ohms like my W7 it runs at 3........the sub stops working when u put up the volume no matter what gain or equlizer is set 2................

 

Well, it's a / series, which means it has RIPS. and it's a 10W7 which means it's an SVC 3 ohm...no way to really screw up that wiring
