Nick Gigliotti Posted March 23, 2012 Report Share Posted March 23, 2012 Looking for some experienced replies, not from any salesmen or company rep because I want unbiased suggestions/advice please! I'll start off with hey, names Nick new to the forums. I've been an installer for multiple shops, lost my license so fell out of the scene, now I'm an electrician on jet's for Boeing, making way more then I was as an installer and wish to get back into it, but step up my game quite a bit. Last system was an Alpine Type-R 15 (2005) with an Alpine MRD-605 (I think 2005 model as well) in my ex's *gulp* 2002 Kia Rio, it was insane. 3.5cuft box @ 35hz. Literally ripped the sheet metal on the body where the trunk latches to, broke it right teh fk off! Anyways, I now have a 2003 RE Audio XXX 12, no amp, but I have thta taken care of, I'm going for 2.5k watts rms, anyways my real questions lie within the electrical system. I drive a 1994 DeVille Concours, 140amp stock alternator JUST replaced with OEM a month ago. Looking for honest advice for how much power I'm gonna need to support roughly 2.5k watts, what brand/size of batteries, how many, do i NEED an aftermarket h/o alt? I have the money to make this as legit as I have to, but who wants to spend more then they have to right? All installation will be done by me, I understand how to add a batterybank, big 3 etc.. not a complete noob ;P Just really need suggestions on batteries, what will i NEED for my setup, I don't want to just go out and buy MORE then i need wasting money, I do not plan on ever going bigger then 2.5k, i don't know if I'll truly ever put 2.5k to the xxx, but I want that flexability and to have the electrical to back it up! TL;DR 2003 RE Audio XXX 12, gonna have roughly 2.5k watt amp, need suggestions on Batteries (what's the minimum I would need to support 2.5k rms) @ 14.4 and will i NEED aftermarket H/o, I have a stock brand new OEM 140amp in my 94 deville concours. Thank you all who take the time to read, especially to those who reply with sound advice! Quote Link to comment Share on other sites More sharing options...
Toby Ratcliffe Posted March 23, 2012 Report Share Posted March 23, 2012 At 12 volts running full tilt you will need just over 200A just for the 2.5k RMS amp. So yes, you will need a HO alternator if you plan to run full tilt with the alternator. If you plan on only using it for demos, and charge your batteries in between runs, you could get away with the stock alternator, and a bank of batteries. You will need to run multiple runs from the front to the back of the vehicle as well. Honestly it would be cheaper to get the HO Alternator, an AGM battery (XS Power is what I would recommend) for the front, and a big AGM battery for the rear. I would also run at least two 1/0 runs from the front to the rear. Quote Link to comment Share on other sites More sharing options...
larrys95civic Posted March 23, 2012 Report Share Posted March 23, 2012 I know you just dropped cash on a new alt but to maintain a 14.4 you will want to look at something that will make higher amperage at idle, as for companies you have Mechman, DC Power, Singer Alts. all great companies. At 2500 I'd do a 2 battery set up, 1 up front and 1 in the rear. As for those you have XS, Kinetic and my favorite the ole Optima yellowtops even though I get hated on for them. and thats my 2 cents Quote Team Superior SPL Former Installer at Driven Sound & Security http://www.drivenss.com All kinds of forsale threads http://www.stevemeadedesigns.com/board/topic/164247-amps-subs-and-misc/#entry2383262 http://www.stevemeadedesigns.com/board/topic/164430-polk-audio-sda6000-sound-bar/#entry2386634 http://www.stevemeadedesigns.com/board/topic/164279-3-michael-kors-watches/#entry2383983 http://www.stevemeadedesigns.com/board/topic/164549-more-items-from-storage/ http://www.stevemeadedesigns.com/board/topic/166967-dd-9518s-amps-kenwood-custom-explorer-dash/ If someone is feeling generous I'd love an original sig LOL Link to comment Share on other sites More sharing options...
rogue Posted March 23, 2012 Report Share Posted March 23, 2012 Welcome back to car audio and the SMD forum! On to the question....... Batteries= XS power. theres a group buy going on right now for their newest xp line. The xp3000 by itself would do the trick based on what XS power recomends. You will not be able to put it under the hood since it cant be around the heat but you could Run one of those and add a D series under the hood and be golden.

MIKE-2U Posted March 23, 2012 Report Share Posted March 23, 2012 make sure before making a big purchase such as an alt, that you look and look. I have bought things then regret it for finding them cheaper, on the same note if you see a good deal take it Welcome back Quote 2006 Jeep Grand Cherokee LaredoPioneer AVH- 3200DVD2/0 Flex-A-Prene Welding Cable (2) Fully Loaded Fi Sp4's dual 1-------> My YouTube Channel <------- Needs more power those woofers will laugh at that turd Link to comment Share on other sites More sharing options...

Nick Gigliotti Posted March 23, 2012 Author Report Share Posted March 23, 2012 Wow, thank you all for the quick replies, confirmation on h/o alt and re-welcoming me to car audio.. this forum is awesome. @rogue & platypus I'll look into this group buy you're talking about, thanks for the info. @toby & rogue I was pretty sold on XS just from half ass researching, but thought I could use some confirmation, thanks! i can't wait to feel what 2.5~k watts does... my 600watt alpine setup was THE loudest, lowest, meanest thing I've ever heard/felt.. i've installed 1k rms systems rarely when i worked at *gulp* circutcity and bestbuy doing installs, it was a good place to start. and my leads had easy 10+ years exp.. they weren't idiots, but we never did really nice higher end installs so.. yeah.
