hertz2beloud Posted June 7, 2012 Report Share Posted June 7, 2012 So I have an xs power d 5100 mechman 220 amp alt and knu cca 1/0. I have 2 rockford T1000's and a T400.4 using a 300amp circuit breaker. The problem is I am not getting anywhere near full tilt without the breaker popping. Is my electrical not up to par or do I need another run of power wire? I am just stumped on where to go from this point so I would appreciate all advice on what to do.

Andrew2944r Posted June 7, 2012 Report Share Posted June 7, 2012 Get rid of the Circuit breaker and get you a fuse holder that uses an ANL fuse. Also make sure everything is grounded properly. Quote Team Ampere Audio Link to comment Share on other sites More sharing options...
hertz2beloud Posted June 7, 2012 Author Report Share Posted June 7, 2012 Ok but if I am popping the breaker would I not blow the same rating fuse and we wire brushed the bracket in spare tire well for a ground. It was bare metal with a brand new bolt holding the ring terminal. That being said I assume my ground is fine at least I hope. Also big 2 up front (grounds) done in the knu premium 1/0 as is the ground in the rear. Quote Link to comment Share on other sites More sharing options...
b-dubs89 Posted June 7, 2012 Report Share Posted June 7, 2012 my opinion is the cca could be a problem Quote Link to comment Share on other sites More sharing options...
hertz2beloud Posted June 7, 2012 Author Report Share Posted June 7, 2012 Can you be a bit more specific. Do you mean I am trying to push too much though it? Would that pop my breaker? Can you be a bit more specific please. Quote Link to comment Share on other sites More sharing options...
Keith77 Posted June 7, 2012 Report Share Posted June 7, 2012 The breaker could be weak causing it to pop when it shouldn't. Get a "ANL" style fuse. Quote Thats cool. Im way too old to be upset by shit like that. Your name is winston. Your own parents hated you even before you were born. My penis is bigger than your penis I'm far from loud and my roof/headliner flaps around like Adam's ass on a windy day. I think it depends more on the structure of the vehicle.

b-dubs89 Posted June 7, 2012 Report Share Posted June 7, 2012 aluminum has more resistance than copper , current flow met by resistance generates heat . i haven't heard much good about circuit breakers either , but it could be that your circuit breaker is weak , breakers do on occasion get weak or trip easier than they should . could also be that the resistance of your cca cable is somehow makeing the breaker think things are not right , due to the resistance and the heat it causes .

Rebel4055 Posted June 7, 2012 Report Share Posted June 7, 2012 (edited) The wire is fine... It's probably the ground location you picked. Also breakers loose the ability to trip after they have been tripped numerous times. Also improper gains could play a factor too., Edited June 7, 2012 by Rebel4055 Quote Rest In Peace mother.

hertz2beloud Posted June 7, 2012 Author Report Share Posted June 7, 2012 Gains are set with dd-1. I will try a new ground. I know when it was just one t1000 I never had an issue so just assumed it was ok. Quote Link to comment Share on other sites More sharing options...
b-dubs89 Posted June 7, 2012 Report Share Posted June 7, 2012 the cca might be ok but my opinion is that your 2 t1000's have to pull close to the rated amperage of 0 gauge knu cca . check your ground and get a anl fuse holder . here's another thought about grounding , most newer cars are unibody construction , body and frame parts made of sheet metal are spot welded and glued together ,i am a bit skeptic as to how well sheet metal can serve as a ground when you start running big amps . i think at some point a guy may want to run a ground up the front and ground to the batt or subframe Quote Link to comment Share on other sites More sharing options...
