Most likely low voltages, beef up your electrical system with the big 3, 0 gauge OFC wiring, put an extra AGM battery in the trunk, turn down your gains until you do so or you gonna blow some sh*t. If thats not enough grab some spare computer fans and make an amp rack with a push/pull fan configuration.
the first option of beefing up your charging system to maintain a higher voltage will do a better job at keeping your amps cool then fans, dont dive into the 2nd option before doing the first one.
