quick question. today i noticed my fuse was blown which is a 100A fuse. I have 2 JL Audio 10W6's with a JL 1000.1 amp. So i went to a near by audio shop and bought a replacement 100A fuse and it blew the second i started the car. So then I went back and bought a 200A fuse and have yet to install it. Do you guys think the reason its blowing is due to the amp or what??? I recently raised the db boost so Im confused why its causing so many problems. Any help will be appreciated. thanks.

 

Don't put a larger fuse in it then what was OEM!!! That will only cause more problems - such as allowing your amp to work beyond its specs and frying a capacitory or resistor on the circuit board, which it sounds like you already did based on a previous post!!!

Blowing fuses means wiring problem of some sort most likely.

Take it to who installed it and have them fix it. If you did your own install, then check your work for o short circuit somewhere in your wiring. Could also be a drastic overload on the impedance. What ohm is the amp rated at and what ohm load are you drawing with your subs?? Speaker wire too small??

Lots of possibilities, but using a larger than originally equipped fuse IS NOT the solution!

 

You just answered your own question. By increasing the Boost, do you mean the +/- boost gain for the subwoofer or the +/- on the line level gain? If it's on the line level gain, you're causing the amp to overload. Look at my other posting to the thread you started. Check the voltage on the RCA jacks going into the amp. Match that level on the amp.

If you boosted the sub output gain then you could be overloading the amp from having it overamplify the signal (distortion) or may have lower than a 2ohm speaker load on your amp depending on how you wired the speakers and what they're rated at.

Never up a fuse just because. It blows because there is a problem with the device. Be glad you're only blowing fuses at the moment, if you increase the Fuse rating you could/will blow the amp.
