[jordanfitted]

i have 2 10" subs bridged and when my car is off wit tha key in it my amp works just fine at high volume but when im drivin tha amp goes into protection when at high volume.... whats causing this?? PLEASE HELP... thanks

do the subs draw too much power? over heating the amp? no idea just my thought.

also what ohms are the subs? and see if your amp is capable of handing it.

Make sure your ground is secure, i had that issue and moving my ground contact to a different spot stopped it
