alpine mrp f250 shutting on and off

[Dbass]

okay so i got it running my 5.25 front and rear, everytime i turn up the bass on the bass control it switches off and when bass goes out or bass not turned up it works perfectly fine. i thought i wasnt having enough power but since i added the batcap 2000 it still does the same, im pretty sure my mids can handle it cause if the bass is low i can blast the mids loud. and i have a y splitter from a set of rca. meaning im running one set only could this be the problem? help me out guys! thanx

(shutting on and off) not the power the sound

I had this problem with my mf300. It would shut off when it was up pretty loud. I re-did my ground wire and it hasn't happened since. Might not be the cause but I would check it. I sanded down the paint and then grounded it. I do that for my sub amps but didn't for this amp for some reason.
