So I am getting ready to install a head unit, 6x's, 6.5" and an amp. I am also going to a dual battery set up with a switch. Where does the amp power get hooked up to? Sorry if this seems dumb, just don't want to have an electrical issue. hate electrical. Right now I have an HEI set up.

I would say it depends on how you want your power running relative to the switch on the dual batteries. Is one battery for starting and the other for running the stereo? Or or you having dual batteries for backup purposes? The amp power will still need to be hooked up to the positive on the battery, but you might need to run a split to both if you want to have music regardless of what battery you are using.

I really wasn't sure on even the dual batteries. I've been SOL with a dead battery and am trying to avoid any of that. So honestly I would like to do it the preferable way. If I go to both will it double up volts though?
-
A perko switch will only allow one to run at a time, like a gas tank selector switch. From what I know most guys run dual bats and a perko. They run and listen to the stereo off of one battery while the boat is running and when it is off. The other battery is a back up to start it and then you can switch back to re charge the first. Or variations of that like using the second battery for stereo on when the boat it off. The voltage would only double if the batteries were wired in series, don't do that lol.

I see. I will just have the amp to one battery. And a bail out battery just in case purposes. Thanks for the help Hondo.

Anytime

I run two #29 from walmart and a perko(1, 2, all) I have two amps... have both + run to all. I have the fuses to them right there as well. The grounds go right to batt. When at sand bar I will switch to 1 or 2 all day. I have my perko on all when motor is running. Been doing it this way for years. If you plan on only one amp then get a good marine deep cycle for that (At least a #27) and then a good start batt.

I have two batteries. One for starting/running the engine and a deep cycle for radio only. My stereo runs on #1 #2 or both batteries. But i only use the radio on the deepcycle (#2) battery when i am beached or floating. I have nwver had a starting issue. I have never had to use Both to start because the #1 is always charged. If you have a large system then maybe use two batteries on the number 2 side. But my single deep cycle has lasted all day running my 10" sub and amp without dying on me.

Thanks guys. I am picking up another 27 and box today or tomorrow and will have this done by my vacation next weekend.

how bout them trojans bra.. now thats out the way i run a locking perko(has its own key) and hide it cuz im :screwy: bout thieves n i use one batt just for start and one for electronics u can always just pull n swap batts if motor batt dies here are some diagrams that maybe will help

I hope USC backs all this hype they are getting. Thanks for the diagrams. I'm cutting in the head unit as we speak. Did a horrible job.
