Guest Posted December 11, 2014 Report Posted December 11, 2014 I am going to be pushing about 2500wrms in my setup. I calculated 2500w/14v to get about 179 amps. I am planning on upgrading my factory alt to a mechman 240amp one. Do you think this would be sufficient? Or would it be worth it to upgrade the front battery to a deep cycle like an XS Power batt too?
SIDE SHOW Posted December 11, 2014 Report Posted December 11, 2014 yes definatly upgrade your front battery & alt, from there if you still have lights dimming and bad volt drop, look into a second battery near your amp in the boot
Miguels Posted December 11, 2014 Report Posted December 11, 2014 240a is sufficient but in reality its not 179a to run a 2.5k amp. its around the 300 to 320a.. amps are not 100% efficient. 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/

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

If I drawing less than 200amps with a 240amp alt wouldnt that be fine?
Miguels Posted December 11, 2014 Report Posted December 11, 2014 thats why i said 240 was sufficient. its not like his wanging it 24/7.. but also the bigger the alt the less batteries he needs 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/

Guest Posted December 11, 2014 Report Posted December 11, 2014 If I add up the fuses on my two amps it sums to 260amps. And I am definitely not planning on burping at all let alone constantly. I just do not want to drop 300+ bucks on a XS batt if I do not need it or if I could get a cheaper batt maybe like Optima or Duralast or something instead.
Broke_Audio_Addict Posted December 11, 2014 Report Posted December 11, 2014 You're still going to need a good batt under the hood and if it was me one in the back. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
SIDE SHOW Posted December 11, 2014 Report Posted December 11, 2014 always match the batterys..... you could get away without it..... i'm a keen believer in overkill for all my electrical. cant hurt having the extra batt in there
