volvowith18psi Posted June 22, 2012 Report Share Posted June 22, 2012 So, while I build my electrical, I'm curious what you guys think it will support realistically speaking. It will consist of the following: 1 Mechman 270 w/ AVBM, 1 D6500, 3-4 D3100's. 2 Runs of Kollouss from bat to back, Big 3, hard wired XS HF1215. WIll be charged once every 2 weeks... I'm pretty much half way done with that, should finish it in the next month or so.... But while I wait, I just wanted some opinions on what I can really expect to support with this setup. Just want to get some ideas so I can piece my next upgrade items based on your recommendations. My goal? Just to be loud as a mother, and still have my car start everyday.

HHR Ed Posted June 22, 2012 Report Share Posted June 22, 2012 depends on whether you use 3 or 4 D3100s since that can be quite an increase. Id say with 4 you can squeeze 15000w Quote Ed Lester ShowtimeSPL Host Showtime Electronics Video MarketingMy old Build Loghttp://www.stevemead...08/#entry511451http://www.youtube.com/showtimespl 5 time dB Drag Finalist Last ride 2007 HHR, current dB 153.5 and bass race 149.4 dB. 153.0 dB on music New Ride, 2008 HHR SS.

volvowith18psi Posted June 22, 2012 Author Report Share Posted June 22, 2012 Wow, that's quite abit more then I was expecting... I was thinking 5k tops.... lol.... Guess I better expand my horizons! (and bank account) lol Quote Link to comment Share on other sites More sharing options...
HHR Ed Posted June 22, 2012 Report Share Posted June 22, 2012 Well XS Power rates the D3100 at 5000w each. I use 85% of that as a more realistic number to play music over a lengthy period of time. Time is the forgotten factor when discussing power Now most amps will make about 85% of the power they draw. Maybe less. So lets crunch those numbers. 4 x D3100s at 5000w each = 20,000w + D6500 @ 3000w. = 23,000w. - engine and car electrical = 22,000 85% of 22,000 = 18,700 85% of 18,700 = 15,895 Now like I said, that is the upper limit of what you have the potential to make. As long as the amps are running efficient, and the batteries are charged up.

volvowith18psi Posted June 22, 2012 Author Report Share Posted June 22, 2012 Great news! I do like to play full blast for hours at a time while driving around doing "irl things" so, even cutting myself down to 6-9k, should leave me plenty of head room! This def. opened up where I will go with this. Thanks!! Quote Link to comment Share on other sites More sharing options...
XX7R Posted June 22, 2012 Report Share Posted June 22, 2012 You can't support 15k rms with a single 270 amp alternator...

XX7R Posted June 22, 2012 Report Share Posted June 22, 2012 (edited) You should have ATLEAST two 270 amp alts for 6-9k rms to have little voltage drop Edited June 22, 2012 by XX7R Quote 1990 Nissan 300zx Twin Turbo - Summer Ride(No system yet, lookin to get it up to 450-500 horse first!)2006 Chevy Malibu - Daily DriverDC Level 5 15", 2 APSM-1500's, 3.88 cu. ft. tuned to 32hz1992 Honda Prelude - SOLD2 18" TC 3hp Woofers on a Crescendo BC3500.1d, 12.7 cu. ft. tuned to 35hz Link to comment Share on other sites More sharing options...
Omega5002 Posted June 22, 2012 Report Share Posted June 22, 2012 I was thinking that a 270 alt would allow you to have 3240 rms on a 12 volt system or 3888 rms on a 14.4 volt system safely.

zack_e89 Posted June 22, 2012 Report Share Posted June 22, 2012 So the answer went from 15k to ~3.5k....Maybe it's somewhere in the middle? Quote 97 Suburban 8 custom PSI Platform 3 18's Link to comment Share on other sites More sharing options...
XX7R Posted June 22, 2012 Report Share Posted June 22, 2012 With one single 270 amp alt you should be okay at around 4k rms. Depending on how efficient your amps are Quote 1990 Nissan 300zx Twin Turbo - Summer Ride(No system yet, lookin to get it up to 450-500 horse first!)2006 Chevy Malibu - Daily DriverDC Level 5 15", 2 APSM-1500's, 3.88 cu. ft. tuned to 32hz1992 Honda Prelude - SOLD2 18" TC 3hp Woofers on a Crescendo BC3500.1d, 12.7 cu. ft. tuned to 35hz Link to comment Share on other sites More sharing options...
