Jamez Posted December 26, 2012 Report Posted December 26, 2012 I'm thinking of buying 3x earthquake ph5000 to power up 6x15, but before I make my purchase I need to work out the electrical supply I'm going to require, at the minute I only have stock alt (90amp) and standard battery I'm aware of needing a serious upgrade any ideas people??
graham0599 Posted December 26, 2012 Report Posted December 26, 2012 What kind of vehicle? You're going to need lots of alternator power and battery reserve. Hopefully someone chimes in since personally idk a lot about these amps My 350z build- http://www.stevemeadedesigns.com/board/topic/174424-2008-350z-build/page-2?hl=%2B350z+%2Bbuild#entry2605678
aps01 Posted December 26, 2012 Report Posted December 26, 2012 from what i know those amps are really power hungry and will "swqallow"whatever you throw at them powerwise...why not trying to get your hands on something more efficient and more powerful so that you can use a couple and not 3 amps?now for alt power you should look at waht is the biggest that well known manufacturers got to offer for your ride(model/engine???)or even make a custom bracket to get an even bgger alt on it if the ones that fir don't do.as for batteries go with the well known brands.you can't go wrong with companies that have been around for years and prooved what their batteries are capable of '92 toy rolla EE90/AE92 1.3lt 12 x 8inch beyma (mids) 6 x beyma CP21-F tweeters(highs) 4 x 15 SPL Dynamics SPL380 D2(walled) 2 x ESX Vision 2500.2(mids,highs) 1 x SPL Dynamics D9-XS(subs) 4 x stinger SPV70 + 5 X SVR platinum 3500P batts 157.2 official on db drag comp-157.3 on same comp but eliminated...still a work in progress...

aps01 Posted December 26, 2012 Report Posted December 26, 2012 you also haven't mentioned what subs you want to power at what ohm load...that would help a lot also '92 toy rolla EE90/AE92 1.3lt 12 x 8inch beyma (mids) 6 x beyma CP21-F tweeters(highs) 4 x 15 SPL Dynamics SPL380 D2(walled) 2 x ESX Vision 2500.2(mids,highs) 1 x SPL Dynamics D9-XS(subs) 4 x stinger SPV70 + 5 X SVR platinum 3500P batts 157.2 official on db drag comp-157.3 on same comp but eliminated...still a work in progress...

Jamez Posted December 26, 2012 Author Report Posted December 26, 2012 Well the subs are dbxi15's and I was going to run the amps @2ohm's so the amps we be 3krms each, and the car is a 3-series bmw, I was thinking maybe remove a/c pump and fit a 250 amp alt, and also upgrade the stock alt?? What do you guy's think??
