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

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 13w7 & 1000/1 Settings

There is no "perfect" setting that can be placed in a manual. It's all done by ear. Your settings will vary depending on the vehicle you are in, the type of enclosure you have, the type of music you listen too, how much voltage your deck put's out. There are many variables, but I can try to give you a basic guide.

First of all you need to know your enclosure. If you have a ported enclosure tuned in the mid to low 30's you may want to set the low pass to around 70-80 hz with your sub sonic set at 30 hz. this will give you the higher bass frequency you need for the loud bass you want, and protect the sub from going too far below the tuned frequency of the enclosure, and losing it's composure.

As far as the gain, and bass boost are concerned, you just have to adjust them by ear. First adjust the radio volume to normal listening levels, by that I mean as loud as it can go without the speakers in the car sounding like ****. Now you adjust the gain first. slow turn the gain control, carefuly watching and listening to the sub.. Adjust the gain to the point of the woofer getting a lil sloppy then back it down a bit until the sound is clean again. Now do the same with the bass boost. if there is a bass boost frequency adjustment, set that as close to the tuned frequency of the box as you can.

If you are in a sealed box the adjustments are a bit easier, and are all about taste. Adjust the radio as described before, and put on your favorite song. Next start udjust thing lowpass frequency to taste, not too high tho, try not us higher than 100 hz in your sub's for better sound. Sub sonic is not quite as important in a sealed box, as there is much less danger of the sub losing control.

Well good luck, and hope this helps!

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)

2 12w6v2's with a 1000/1

I dont know how you blew both subs with a 1000/1. the subs have an rms of about 400w. according to jl,the sweet spot for them is about 500-600watts. are you sure that you had the jumpers wired correctly and the amp at 2ohms?

Setting low pass and bass eq

Hello, i have a hifonics brutus also, in the manual it states to set the eq at half way, so that there is no clipping or at least to prevent clipping , the eq will make the bass punchier, if you do go pass half way, i would recommend to readjust your gain settings, also check your head unit settings and make sure everything is flat, bass, mid bass etc. example i had my eq past half but i had my gain at mid way, it was hitting hard, then i tried turning the eq all the way down and the turning up the gain and the bass was smoother so it depends where you set it, and what settings you have on your head unit tone control (bass, treble etc)
