[QUOTE="blue, post: 1471107, member: 562889"] OK , I need Gurus here .... Facts please , no opinions. I only have one battery ( stock ) , and it's mounted in the trunk for lack of underhood room. The wires running to the front are 1/0 , and I've done the big 3 already. My two Arc amps are 3 feet from the battery , and my gains are set rather low due to my 8 volt pre out on my head unit. I'm running 1700 watts and listen to rock , REALLY loud. But my car is a SQL car and not an SPL monster .... so I'm somewhat suprised at my dimming headlights. My alternator is PCM regulated , and so I can NOT simply get a HO alternator , because my PCM is not giving out more voltage without an 8 second period of CONSTANT demand by my car ..... My ONLY option is battery assistance of SOME kind ..... Here's where the HELL starts .... I'm getting VERY conflicting information from the so-called Pros at Optima , Odyssey , and Ohio Generators ... Not to mention the local shops install managers !!!!! The first thing I was told is that I needed a starting battery , because they act more like a capacitor and discharge/recharge faster ... but Optima says that is incorrect and just opposite ... buy the Yellow top they say. Then I read this on here : [B]What differentiates a deep cycle battery(yellow/blue top) from a starting battery(red top) is for the most part the difference between the thickness of the plates. Deep cycle batteries have thicker plates than a comparably sized starting battery so the starting battery can fit more plates into the same volume and the starting battery will react quicker to load changes. Basically the starting battery will be able to react to transients faster than it's deep cycle counterpart and usually can produce more current. [/B]" But Optima says NO to this theory .... Here's my two choices as I see it : Odyssey makes a flat dry cell motorcycle battery that will fit underhood PC-680 , so i could fit this underhood and daisy chain to a new dry cell battery in the trunk. Using TWO batterys .... OR I could just buy one BIG battery for the same money as the two and place it in the trunk. [B][COLOR=Red]Which way would be most likely to stop my dimming headlights ... REMEMBER , the underhood battery would only be a small dry cell.[/COLOR][/B] [B][COLOR=Red]If I went with option A , I would probably get an Odyssy PC-680 for underhood and an Odyssey 950 for the trunk.[/COLOR][/B] [B][COLOR=Red]If I went with option B I would get a single Odyssey PC-1250 or PC-1750 for the trunk alone.[/COLOR][/B] thanks [/QUOTE]
