Currently I have 2 batteries, a starting battery and a blue top wired into a perko switch charged by a 65amp alternator . The system I'm running is 2 Syn 6's and a 400 watt clarion amp. I have a budget of ~$750.00 and I need some advice on new batteries, an on board charger, isolator, and possibly a capacitor. Links to sites where I can find the equipment for the best price would also be very helpful. The boat is a '01 Tige 21i with the mercruiser 350.
Thanks for the help!!
