Output challenges and recommendations

[BCotrell 10+ year member]

Hey guys, I have an Fsd 2600 on two Xfl 10’s down to one ohm on a 250 amp alternator with a 34r agm in front and 31 agm in the rear. My output is **** and I can’t figure out why.

rca are good, checked that

fuses are good

mechanjc said tension of belt at pulley is good

recently swapped front battery from regular battery to agm. Is it possible the front lead acid damaged the rear agm?

last thought it’s the amp, anyone have a recommendation for a budget 2500-3000 Korean

been a while since I had to think about car audio purchasing.
