    honestly you may be ok just with a couple more batts with out buying a alt. i would get rid of that yellow top and get a better agm battery for under the hood and another group 31 to go with the one you already have. i have a bc3500d and it drop only to 13.7v @ full tilt and thats at idle, im pretty sure that my amp puls more then your M3b does and my alt is smaller then yours.

    How long does it usually take? How hard is it? It sounds kinda fun.
