How would you wire me

Also I think I would run one alt to one batt and other alt to other batt. I dont know how your going to get all those cables on two posts lol. Did you get the other alt mounted up yet ?

I have bus bars on batterys and have alts feeding baterys and caps connected to buss bars as well.View attachment 26556679View attachment 26556680 i dont know if you can see anything in the pics. I dont want to dis your batts but I think you could do way better if you could get some car audio baterys because I am guessing yours are only about 50-55 ah where batts like xs or juicebox or lots of others in a group 31 are 110 ah so double the capacity in only a little bigger size and I think you have room. But try it with the caps first and see ?

Whats 260 ? alt amps ? I honestly would tell you to get two audio batterys first, atleast 110 ah each then you would be pretty solid for 2.2k then the caps could be added to help the dips in voltage later but remember they discharge really quick and then need to recharge thats the reason you need alot of them to work well. I ran a 2.5k on two of those style batterys (group 78 )and a 140 stock alt and did ok but voltage was really low at time sand fried a few amps too. Its just not a big enough storage to pound hard on it for very long. I think sell your baterys and buy two juice box black cherry batterys which will double battery capacity. Then go on from there. I think you can get those batterys for around 200 bucks each. Juice box makes good batterys and alot less than XS too. IMHO everybit as good I have three for over three years pounding hard all day every day ha ha !

Oh ok well try to sell your batts , they look new ? If you could get a hundred a piece you are there or real close huh ? I just dont think you would have enough battery or alt power to use caps and esp only one bank. Caps are great on strong electrical but there really just to fill the lag between slow battery discharge and slow recharge which give us the up and down voltage readings. Probably not what you want to hear but money you spend on a good electrical foundation will take you far in our hobby. Trust me I was in your shoes a few years ago.

I am sitting hear thinking about your set up and you will have two 90 amp alts so your car uses - lets say conservatively 60 amps that leaves you 30+ 90 =120 amps for stereo not alot but maybe a little better than I had ? So mount up your second alt and see how it acts ? Then change batterys as I am sure you will probably need them but gives you time to save a bit and sell your old ones. then if voltage is still diping low at times you could do caps //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
