Fuse keeps blowing when sub volume is turned up

I have a JL 1000/1 powering a 13.5 w7 runing 4GA with a 100 AMP fuse and a 4F cap, i also have a good ground. The system works fine, but when i turn my subwoofer output up on my head unit it hits real hard for a good 10 to 15 min, before the fuse blows. the amp warms up as usual, nothing to hot. should i swap out the 4GA cabel to a 0GA? will this most likely solve my problem? i purchased the sub from a jl retailer and the amp i got from indoaudio.

The amp draw rating on the amp is 100 you need to put a larger fuse in, such as a 150 amp, it would be a good idea to go to 0 ga but not needed. you might also want to upgrade your altenator.

Thicker wire, and make sure the connections are good and tight. Use high quality high copper wire and make sure the ground is as short as possible, and that you are grounding it to the chassis properly, as in sanded, clean and tight, and short as possible.

I would recommend that you go to a zero gauge wire if you up the fuse to 150. The current that you will draw is also going to increase and will cause the wire to get warm if not melt if you stay at 4 gauge. Remember, when you increase the fuse rating, it allows more current to go through the wire.

The thicker wire is a great idea. the draw rating on the jl 1000/1 is not 100 amps. its 75amps. but, if you have another amp in the vehicle for other speakers, you will then need to have a larger fuse.

I have a 1000/1 amp running two W6s in my truck along with a 300/ going strictly to my highs, i also have a capacitor for 1000 that only runs for the 1000/ amp and a JL audio 100 amp fuse for all of it....

You need to get another capacitor and wire it in series with the fist cap when you crank the volume your system is not getting enough power from the alternator this is called surge current. In modern electrical systems we use capacitors to compensate for these surges.

I have installed a 12" w7 and jl 1000/1 v2 amp. I was useing the bass knob untill i found out on the jl website that its not needed for this set up. I was haveing problems blowing 80 amp fuses so i went...

It is NEVER a good idea to increase the values of fuses . Chances are you have internally damaged your amp. The next time you are faced with this problem you need to find out why your amp is blowing fuses and not keep changing the value of the fuse.

Jl 1000\1 v2 and 13 w7

it depends on how you wired your 13 w7 did you wire the dual voice coils up or down?? the w7 comes with a book and it has the 1000/1 settings you need and then there is a guide that comes with your 1000/1 v2 and on page 14 it tells you how to set the gain accordingly to your ohm load for perfect sounds with little to no gain overlap (you can set the gain louder if you don't want maximum sq and are not worried about clipping cause a 1000/1 shouldn't blow a 13 w7 from overpowering only from clipping (and since the w7 are practically bullet proof clipping takes a long time)

Blown fuse

What size fuse are you using?

Have you checked the speaker to determine if it's damaged?

Do the speaker and amp produce clean sound up to the point where the fuse blows?

Jl 1000/1 amp not working

If I'm not mistaken, the blue light is the low voltage indicator. You need to confirm that the voltage ON THE POWER SUPPLY TERMINALS of the amp never drops below 11 volts. If it does, the amp will shut off. It's possible that you have a bad connection or even a defective fuse that's causing the problem.

JL recommends a 100 amp fuse for the amp. If you use a fuse that's too large and something goes wrong, the amp may be very severely damaged (possibly beyond repair).

What eq settings do i need

Hello ed4037, If you are blowing fuses this means that you are drawing too much current check your impedance value on your amplifier it should be 8 ohms to match the subwoofer's 8 ohms of impedance. In addition make sure that you have the proper value fuses. In other words you should not be tuning the amp not to blow fuses, because you should be able to go to full amplitude on your amp without blowing anything. As I alluded to this sounds like an impedance mismatch problem. I hope this helps, Thank you, Shuttle83
