My infinity reference 7540a amp cuts in and out with heavy bass when the ''loud'' feature is on. I redid my ground, remote wire, shortened my power cable, and double checked all speaker connections. I dont know the specs on my sub, but its a 12'' Audiophile. The sub is bridged on half the amp and the other half is powering 2 stock 5''ish speakers.(Older Eclipse head unit All this equiptment is old, but in a 95 Jeep Wrangler im just looking to add some thump, not achieve greatness! Is the mentioned equiptment decent?

Sounds like ur gains are set to high and is going into protect mode
also what ive seen happen before is the speakers (if mounted in metal shelf or door and arnt bolted down correctly can flex under bass notes and flex the speaker that much the termanls short onto the metal and amp hits protect mode
(rare but worth a look if you think u have elimanted most other things Had a dude come to me when i was working in sydney with this problem )
also could be things like clipping protection , overheat protection ,amp drawing to much current from the alternator
do your lights dim when you hit the bass notes ?
get back to me and im sure we could solve this problem
