alt

The best way to tell what size alt you need is to check your amp draw from your stereo and then match your alt (if possible) to your system draw. I can tell you from experience the 70 amp wont replenish your batteries at all if you are running your stereo at max capacity for any length of time. It was a good move using the trojan t-105s they last a decent amount of time and can be depleted many times without damage. PM me if you'd like to know how I have mine set up. I'm running a 5 amp system, 6 hlcd's on the tower 6 subs and 4 in boat wetsound 6.5s. I'm pulling around 200 amps at 75% max volume.....
