Next Tuesday I'm having a stereo over haul done to my boat. I'm having one pair of Rev 10s installed to the tower powered by a syn 4. 2 pairs of XS650s and 1 kicker solo baric subwoofer (about 500 Watts rms) all powered by a syn 6. Right now i currently have two interstate 24M-XHD 800CCA 1000MCA.
will i be ok with just two batteries or should i add another interstate to the power plant??
