Bump4life Posted December 30, 2011 Report Share Posted December 30, 2011 I am running a DD M1C and want to run at .5 ohm. I have big 3 done. stock 100 amp alt. 95 mercedes benz. see complete system in sig. voltage never currently drops below 12.8 on hard bass hit. How many batts should I add to supply amps with proper amperage and current? will i be able to do this w/o a H/O alt? in addition which is a good battery brand to look at or specific model even considering cost is an issue and what about if cost is not an issue. My max draw in amps from everything is around 230 amps ( DD M1C (150A) + DD c2c (40A) + JL 400/4 (40A)) + car draw. OR other general electrical upgrades I should do. I'd like to stay away from a H/O alt if possible. But if I have to let me know. ALso I'd like battery to be physically small if possible. less than 6 inches width other parameters can be whatever. I might be able to do 6.5 inch Quote Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

SPL Blazer Posted December 30, 2011 Report Share Posted December 30, 2011 Could try a smaller XS Power battery in the front, like a D5100, and go big in the back, providing you have more than 6" width in the rear. A single D5100 and a D3100 should be fine. Best thing I can suggest is going with those two batteries and see how your system responds, if you have voltage drops or dimming then add one more D3100.

Miguels Posted December 30, 2011 Report Share Posted December 30, 2011 i was looking around and found a video on youtube and it showed that running extra betteries wont help since your stock alt wont recharge them properly as you play music and soon it will die on you for over working, if you go that way make sure you charge your batteries everynight so it wont harm your stock alt, also look into getting a HO alt they go for 450 a good battery goes for 359 if you need 2 of them then the HO alt would be the way to go Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Bump4life Posted December 30, 2011 Author Report Share Posted December 30, 2011 i have an excellent stock battery already and really dont need to replace that. yes it is not an after market bat but i believe it is still quality. and has proven thus far to provide my system power. would adding 1 xs power D5100 in back or kinetick Hc 1400 be enough? and i rechecked my alternator and believe it is 115 A actually Quote Buyer/Seller Feedback Thread: http://www.stevemead...5015-bump4life/ MB C220 153 Trunk Car Build Log: http://www.stevemead...d/#entry1840136 MB C280 Ipad Dash SQ Build Log: http://www.stevemeadedesigns.com/board/topic/194484-bump4lifes-new-benz-tony-c-relay-kit-pictures-ce-electric-audison-front-stage-installed/ My SPL Log: http://www.stevemead...__fromsearch__1 BMW M340 xDrive Stock, for now.

sayhuh? Posted December 30, 2011 Report Share Posted December 30, 2011 (edited) .5 ohm? You best work on more than your battery. Edit: Alt, XS Power batt or sell subs and get two d4 subs. Then you'll be 'ok' with just a batt. Edited December 30, 2011 by sayhuh? Quote Blown Link to comment Share on other sites More sharing options...
IBleedMusick Posted December 30, 2011 Report Share Posted December 30, 2011 (edited) Why .5 ohm? The amp does 1200w rms at 1 ohm on 12v and the subs are what 750w rms each why stress the amp out like that and sayhuh? is right if you plan on stressing it the least you could do is feed it right H/O alt and atleast 2 batts in the back I would go XS. You cut corners you're going to fry that equipment in a heartbeat. Edit: Didn't realize they were d2 subs so retract my original question it now makes sense why you want to run at .5 but I wonder what that amp does a 2 ohms ever thought about that.

You cut corners you're going to fry that equipment in a heartbeat. you obviously don't know about DD? After box rise I should be way over 1 ohm. MY only question here is what kinda electrical do I need? can i get away with 1 or 2 extra good bats and big 3 or am i gunna have to shell out the cash for a H/O alt. I know what I'm doing as far as equipment goes and like most people I'm on a budget. I want to know the minimum I can do to get away with it. Also see the 1500 watts amp tests by Fecupe and youll see the DD M1b (I have current M1 series amp M1C) does 2200rms or at least its support that it can do that with subs wired at .5 ohms and about 1 ohm after box rise. so 1 or 2 batts (xs or kinetik) wont cover my electrical needs? i should go with the H/O instead?

Miguels Posted December 30, 2011 Report Share Posted December 30, 2011 go with the H/O alt you will fry your amp, you dont have to get a very expensive one just one that can handle the demand Quote my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...
Bump4life Posted December 30, 2011 Author Report Share Posted December 30, 2011 good video. currently my amp does not even get hot and i have bumped for hours straight before? and my voltage does not drop below 13 maybe 12.8 on really low notes. can anyone explain that? is there any way to see if alternator is affected?
