Cardboardcat15 Posted October 2, 2010 Report Share Posted October 2, 2010 Im starting to plan out everything for my next system (Last one for my current car) so I can get a rough idea of just how much $$$ I need to save. It's all still pretty far out of reach, but I'm a planner. My current plan is to run 1200 watts RMS for the subwoofer amp (SAX 1200D), and probably an additional 4 channel amplifier for my mids and highs. Nothing crazy, but enough to power a decent set of comps. So my question is, could I get by going with a 150 amp Mechman alt off of two batteries? (most likely another Optima red top) I want to see no less than 14.0 while driving, and a decent idle voltage. I figure going with the other model for my car (220 amps) from mechman would be better, but if I can go with the 150 amp alt it'd be easier. Any thoughts? Thanks for any and all help.

hdorre Posted October 2, 2010 Report Share Posted October 2, 2010 Yes, its possible. A single D3400 and VCM would be fine. You really need the VCM though Quote On 5/8/2011 at 7:38 PM, Kranny said: On 5/8/2011 at 7:35 PM, 'Maxim' said: It hurts me inside when I read stuff like this and remember you're 15 LMFAO so true Mitsubishi 3000GT (Old Build) Headunit: Pioneer 80PRS Frontstage: (2) McLaren Audio MLT-2 Tweeters & (4) PRV Audio MR Series Neo 6.5" Mids Substage: 4 15" Hybrid Subs - Tantric Motors & Sundown Softies Amps: Banda 2.4D Amp (Tweets), American Bass VFL 350.4 (Mids), and (2) Ampere 3800s Electrical :Singer 260A Alt & JY Power Lithium 2005 Chevy Colorado Ext Cab Headunit: Pioneer 80PRS Frontstage: 4 PRV 700Ti Tweets & 6 10" Delta Mids on 3000wrms Substage: 6 Fi BTL 18s in a 4th Order Walkthrough on 3 Wolfram 4500s Electrical: Singer "390" and JY Power My Official Feedback Thread Link to comment Share on other sites More sharing options...
melonhead Posted October 2, 2010 Report Share Posted October 2, 2010 Could he just keep his stock alt and add a 2nd battery? Quote Link to comment Share on other sites More sharing options...
Team_DC-Derrick Posted October 2, 2010 Report Share Posted October 2, 2010 Could he just keep his stock alt and add a 2nd battery? no, because once he trains the batts, its going to pull from the alt... upgrade alt to compensate for the power you have is the only way to keep your voltage up...

Cardboardcat15 Posted October 2, 2010 Author Report Share Posted October 2, 2010 Yeah a VCM was in mind also, I forgot to add that in.

Yeah I wouldn't add a second batt to my current alt...its only a 60 amp lol. Quote My Channel on YouTube.

Team_DC-Derrick Posted October 2, 2010 Report Share Posted October 2, 2010 I ran 2 kinetik 2400s in my hatch area, and a 1400 up front, and my stock alt couldnt keep voltage up, it would consistently be at 12 or lower... upgrade alt + batt = great combo dont forget to do the big 3 as well Quote The DC Integra 3 18s to 6 15 build log Team_DC-Derrick's Youtube Team DC Audio where theres a will theres a wall.......

melonhead Posted October 2, 2010 Report Share Posted October 2, 2010 I have a 70 amp alt on my Civic and I pretty much asked the same question as you and I was told I just needed a 2nd battery. I didn't specifically ask if I'd get a steady 14v though. Quote Link to comment Share on other sites More sharing options...

And regal, thats probably why people said just to add a second batt. I want to stay above 14v almost all the time while bumping. Stop signs and Red lights are my worst enemy. >:0 Quote My Channel on YouTube.
