Well i got the new system all hooked up. I couldnt have picked a hotter weekend ,107 degrees all weekend. It must have been 115 in the garage! Anyway the 1315 worked great out on the sand bar this weekend. I ran the radio all the way up for about 4 hours and it then started to cut out (Bad Battery). I hopped in the boat and she fired right up, man did that feel good cause it does always end up like that... I do have more Q's thow. How do I hook every Accessory up to that battery? run another switch or something ? Because when I want to run the radio I have to push in the power button next to the key and the accessory button too. The radio power line coming out of the radio is hooked up to the 2nd battery. In the future I want to run amps and subs. So I guess now I am curious as to how you all hook up your amps,subs and pumps along with anyother extra things you are running.
