External battery source help/information MC420B Amp

I have an MC420B and when using wired to motorcycle battery the sound will break up really bad when I accelerate but will work fine at idle or not under acceleration. I was thinking of using an external battery to take it off of the motorcycle charging system. Does anyone know what mc420b draws in power so I can get the smallest 12v battery that could power the unit and would last approximately 1 hour of usage?

My radio turns off and never plays constantly I don't know what's wrong with this radio you look at it minutes this is this is a brand new radio imma let y'all see it
I would not suggest this product to anyone that I do not hate

Be sure to make sure that TA is turned off and that Standby Mode is disabled. Those are the issues I had that caused similar problems.
