Protect mode with loud music

Running Duner Tunes system with 250w amp in Rzr 900xp. Also has winch. Installed system and winch when unit was brand new in 2012. It seemed to work fine thru 2013 and last summer (only used it very little last year due to work schedule) the amp would cut out if music turned up loud. Checked code and red lite on amp flashing and trouoble shooting says low amps so goes to protect mode. Battery is fully charged. Would upgrading to new or bigger battery help?(battery in rzr is the original).
