Jbabycsx Posted September 28, 2010 Report Share Posted September 28, 2010 What are some things to look for when shopping for an extra battery? How do things like amp hours and cca relate to using the battery to power amps? 2000 GMC Sonoma AQ20 FTMFW! 4 DC XL 15's Cadence ZRS-C9 Infiniti Kappa 3.5's and 6x8's Bravox 6.5 components Link to comment Share on other sites More sharing options...
dugee81 Posted September 28, 2010 Report Share Posted September 28, 2010 uhm i read this on this site or CACO, for reference youll want to do 1ah per 10 watts. not sure if that is completely correct though. 200a alt. by Excessive Amperage hc800 under hood & 2 Deka 9a31 in rear 1/0awg + big 3 SAZ 3000D HDC3 18" @ 2 ohm Link to comment Share on other sites More sharing options...

That sounds like a lot! That would put me at around $1000 bucks in batteries just to power my 3000d. 2000 GMC Sonoma AQ20 FTMFW! 4 DC XL 15's Cadence ZRS-C9 Infiniti Kappa 3.5's and 6x8's Bravox 6.5 components Link to comment Share on other sites More sharing options...

hdorre Posted September 28, 2010 Report Share Posted September 28, 2010 I do watts/.7/14.4*.5 .7 is for efficiency, 14.4 is for voltage, and .5 is because SONGS don't play constant tones. From there, I subtract alternator idle amperage from the top equation.
