bernymac Posted October 2, 2006 Report Share Posted October 2, 2006 Hey guys, new to this forum and decided to go here but I needed more input in my situation. I need some input on some alts and batteries for a 5krms system. System includes. 2 HD315's 2 MA P3000.1 1 MA P800.4 CDT components. I roughly say 5000rms because the amps put out 2500rms at 14volts. I need to know how big of an HO alternator I need to go with and if two Odyssey 2150S or two Kinetik Batteries would be fine. I know about iraggi but is there something that I should know about alternators, because sometimes people describe them differently with internal and external regulator? I was thinking about a 240amp alt but wasn't sure if that was enough? I would like to stay away from a dual setup as much as possible. Also whats a batcap? and should I run a battery isolator. I know its a lot of questions but if someone could help me just a little that would be appreciated. thanks. Link to comment Share on other sites More sharing options...
dmanson Posted October 3, 2006 Report Share Posted October 3, 2006 depending on what kind of car or truck you have ... get the biggest alternator, i've heard they go up to 300 amp. you should run a battery isolator is you'll be having multiple batteries in your car(as in a battery or two in the back). a batcap is a batter/capacitor. here they work quite well and are small at that. 2-DC 15XLM2 D.7s 1-DC 5K amp (1) XS Power D6500(UNDERHOOD) and (1) XS3000(REAR) 3 runs 1/0ga for power and 2 runs of 1/0ga for negative. (2)-RFT165s components, ...... 4 separate 1 inch tweetersRF T600-2(fronts) Punch 450.4(rear) Audiocontrol 3.1. DC power 260amp alternator w/MLA Module Link to comment Share on other sites More sharing options...
Guest MegaloManiac Posted October 3, 2006 Report Share Posted October 3, 2006 I have a 200A for my 00' accord, and i CAN run a 5k system daily, but right now i amp only pullin about 1800 watts, little less than 1200 for my NINe1 100watts for my computer and 500 watts for component amp. i say get between a 200A and an 300A...im no pro so its merely just an opinion Link to comment Share on other sites More sharing options...
bernymac Posted October 6, 2006 Author Report Share Posted October 6, 2006 Ok I decided to go with a Iraggi 300amp alt. But whats safer for me, an internal regulator or external. I don't know how to mess with this and is it truly necessary or just a basic option. I would like to keep about 13.5volts+ but no where near 12 atleast. Would an internal regulator be able to do that. Also I got two odyssey 2150S if that helps. I'm buying the alternator on monday so any help from now till then would be appreciated, thanks.

Guest MegaloManiac Posted October 6, 2006 Report Share Posted October 6, 2006 your goal should be to maintain the voltage at around 14v. no doubt that alt will be able to hang with your system. extra batts will help you maintain the battery levels.
