i have a MMATS 3000.1 and 2 15" kicker L5's. i turn on my car and no bass (amp is in protect mode). turn off the car and turn it back on and it works fine. i thought maybe the gain was too high and i lowered it, but didnt work. what do you guys think i should look at?

thanks

 

please provide more details, as this can be LOTS of issues.
can you replicate this problem?
when did this start?
was working normal?
re-check all your wiring. ALL wiring.

 

Check all your grounds, check voltage across the amps terminals, check impedance of the woofers (you'll probably have to unhook from the amp to get a valid reading).

What do your electrical upgrades consist of? What impedance are you running the amp at?
