I tried switching my lanzar amp to my jl 1000/1 amp myself last night and as i plugged in the ground.. some smoke came up from where the ground and 12v cords meet the sub.. it wasnt much smoke, just a little. so i plugged my lanzar back in and today at lunch went to get it installed and it seemed to be hittin when i left the car audio place.. but its not hitting like it should. the lanzar hits harder. what went wrong? what does that smoke mean? how do i fix it? thanks. i am worried sick. those amps arent cheap.

Re: jl 1000/1 amp not working w7 like it should
If you see smoke, it's virtually always the power supply transistors. There are several things that can cause it but sometimes, they simply fail. I will generally work with people who want to repair their own amplifiers but the this JL amplifier is complex and not always an easy amplifier to repair.
If you can't find a local repair shop to repair it, you'll have to go through an authorized JL retailer to have it repaired by JL.

The jl100/1v2 puts out the same amount of power between 1.5 - 4 ohm loads so you dont have to really set up anything to match your sub- wire the coils in parrallel and plug it in- set infrasonic(subsonic) filter at 15 hz(lowest) set crossover piont at close to 80 hz set gain about half-or if you kow the voltage from your source unit match the source voltage to the amps input voltage setting-it should pound like a champ with no problems
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)
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).
your w7 13's are dual 1.5 Ohm, but according to JL website, are 2.41 Ohms when the coils are in series. Each 13 connceted to each amp with voice coils in series is your best bet. The amps are designed to put out the same amount of power from 1.5 to 4 Ohms. If you parallel the voice coils, you end up with .6 Ohms and the amp will go into protect mode. You'll be drawing a lot of current, so you may want to think about 1/0 guage power wire, upgrade the wire from the alternator to battery (usually only 8 guage) and think about multiple batteries.
