alaskanzx5 Posted June 23, 2013 Report Share Posted June 23, 2013 electrical will be 1 singer 250amp alt with external adjustable regulator big three with 1/0 gauge. including a ground from an alt mounting bolt to the frame. biggest batt I can fit under the hood is a d3400, might be able to fit a d3100. I will be able to fit a second batt no bigger then a d3100 in the trunk (might have bang the metal on the back side of the back seat in a bit to make it fit) then ill have a 10 farad Rockford cap ill be running a t1500.1bdcp @ 1ohm and a t400.4 front channel at 8ohms rear channel at 4ohms. 300amps of current max. right now I have 1 run of 1/0 gauge but only have the t400.4 in. im sure 2 runs would be enough for this setup and that's not my worry. im going to eventually upgrade to a t2500.1bdcp. 2 agm batts and the 10 farad cap will be the most I can fit. so will 2 runs of 1/0gauge be enough for that. in theory 2 runs is good for 600amps and between the t2500 and the t400.4 ill only be pulling a max of 400-450amps. so with that being under the 600amp rating of 2 runs would I be safe to call it a day with that or should I do a 3rd run? I want to stay in the lower classes for usaci and iasca and im fairly certain it limits me to 2 runs ( correct me if im wrong ) t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

goodvibez Posted June 23, 2013 Report Share Posted June 23, 2013 assuming the two runs are both positive and that you have an equal amount of ground connection under the hood, and will ground everything in the back properly I think 2 runs should do just fine:) Anymore than that would be for peace of mind rather than to prevent a bottleneck in currentflow. Just make sure you ground everything with as much cable as you power it or there will be a bottleneck situation. Oh and properly fuse it:) Funny how the people who have a louder system than you will usually give you a compliment about your setup because they know how much blood, sweat, time, and money you put into it. The people who criticize or try and one up you....have a p.o.s to no system at all and will tell you all about this "other" guys system! Saddley I'm sure if I meet this "other" guy...he will probably tell me he thinks your just as annoying as I think you are! I'm not compensating, just proud of fabricating!

alaskanzx5 Posted June 23, 2013 Author Report Share Posted June 23, 2013 my only worry about 3 runs is if I wont be able to stay in the lower class because of it. im going to go double check the rules real quick t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

alaskanzx5 Posted June 23, 2013 Author Report Share Posted June 23, 2013 ok, usaci from what I could find has no rules against it. iasca does though. cant have more then 2 runs in the stock class so if I do 3 runs then ill be put in the stock t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

bighossf150 Posted June 23, 2013 Report Share Posted June 23, 2013 2 should be just fine for a 4k set up, hell I have 3 runs of + and 3 runs of - from under the hood of my.truck with the 4 3500's and I'm using cca too.

SnowDrifter Posted June 23, 2013 Report Share Posted June 23, 2013 2 runs of ofc is fine for a 250a alt. Lol at the people telling you to do more. You could... But it's diminishing returns. Its a 250a alt. No matter how much power you are pulling from the back batts the alt will put out no more than that. More runs will only gain you a tenths in front/back voltage drop.
