Sub cuts out? HELP
Sub cuts out? HELP i've got a pioneer 760w amp (380rms) runnin to a 10" solo baric L7 in a stealthbox in my t-top 00 SS. the sub/amp combo is hooked up through a linelevel converter tapped into the speaker outputs via the wiring harness to the stock monsoon amp in the rear. my problem is this, when the volume reaches a certain point the sub will cut off but the on light is still there for the amp. is it that the amp isnt getting enough power supplied through the cable to the battery? or something to do with the line level converter running to the wires coming out of the stock amp and that the two amps may be cancelling eachother out?
the power cable right now is a 10ga

well i know that in order for my subs to work with my factory headunit and amp i had to get some box thing that hooked to the back of the headunit in order for it to work properly. something about our headunits dont have something to run a sub without it. but if your runnin yours from the amp then might be a wire problem or a fuse.

your l7 is pulling to much power from the amp when its hitting the higher volume causing your amp to go into protection mode. Those L7's need a lot of power, if you were to get a bigger amp it would more than likely solve your problem. I had an 12"l7 running off a audiobahn A8000t mono amp which puts out 800rms and the sub was bumpin hard. Like i said those l7's need some decent power to work to its potential

01Low, turn the gain on your amp down a touch and give it a try.

That is if its in protection. It almost has to be those things want at least twice that much RMS 
. Try to have a buddy hook up his bigger amp (anything around or over 700rms will work) in your car using your same conections and see if you can turn it up.

Also what about the 10gage power wire? Shouldnt that be at least 8g? TECH Apprentice

Make sure your line level converter isn't just sending a raw signal through rca's It should change it to a consistant voltage for the amps if you have it conected through rca's. If it's not it could be sending a distorted signal to your amp thought the llc. If it's doing the that, the amp may kick into a thermal protection mode.

You want louder? By a bigger amp. Don't get greedy.
and no that's the the problem

not saying that the amp is absoloutly his problem but it could be.Now as i said before arguing with this guy, try a better amp on your curent conections, and test all the other posibilities.
