plus the batt charges automatically when the car is switched off.
in my case i feel its 270 well spent :)

if u got a hi-powered system then u will NEEED a capacitor i doubt an optima battery can provide ur amp with 14V.
if ur right then yeah i guess the onli good thing about the optima IMO is that it charges when the car is off.

they hold more charge and they charge up when flatt.. thats why they are good for car audio

i recently got the century ULTRA for $90 from autobarn and they last long but my lights were still dimming abit, i bought a decent capacitor for $80 and now everythings good my sub doesnt clip any more i've put the gains up heeps more without any distortion or dimming of any kind :)
dont upgrade ur battery for better power just get a capacitor (nothing fancy) and ur system will benifit alot more.

I wonder if the cap will kill the battery quicker if used while the alternator is not running. Because with each thump of the sub, the cap is drained slightly and the battery gives a sharp output to top it up. Keep us updated on your battery life. But I'll look at the cap too. $120... hmm, the ground cables that come with it should be a nice upgrade as well.

For me, Optima yellowtops are interesting because they are gel-acid-electrolyte. I prefer those over liquid acid.

Optima batteries don't charge when your car is off!!!!!!! Your alternator is not running.

caps are shit IMO, they don't do much for system at all. In most situation you will benefit from a larger, higher capacity deep cycle battery. i bought a d51 optima for my civic and it performaced so much better the the ussual cheap batteries.

light dimmnig was greatly reduced, voltage drops were less with the optima and better starting too...

hey i think i need to change my battery terminals too, but if i change them i think i need to change the cables that hold them too cause i'll have to cut the cables and they'll be too short, the - is pretty easy its ground, but the + is a pain in da a** its connected to several places including the fuse box, does anyone know on how about i would go in doing this? i wanted to get the gold plated terminals.
p.s are they normal 4gauge power cables? cause i can see several other cables inside of them all seperate...

:rolleyes: No, you will find that a deep cycle battery will do a WHOLE lot more for your system than any capacitor in the same price range.

:rolleyes: No, you wont if you upgrade to a decent battery and use suitable gauge power and earth cable.

:rolleyes: No normal car battery(deep cycle or not) will provide an amp with a true 14v even with the car running :rolleyes:

:rolleyes: ummm......no they dont. :rolleyes:

but $300+ for a cap is? I know where I'd be spending my cash and it wouldn't be on a cap. ;)

Deep Cycle batteries are a VERY wise choice for car audio, they have a much longer life span than a normal lead acid battery, can be run flat many times without dramatically reducing the performance of the battery and will allow for a longer engine off running time for your stereo system and still alow you to start the car after it.

very well said. :thumbsup:

go buy yourself 1 r 2 Aeropro distrobution blocks with 4x8g inputs.

then wire the factory + cables to these and run fresh 8g cable from the distros to the battery, effectively lengthening the factory cables ;)

i didnt say yellow tops charge when the car is off qball said it, read the sentence right and get ur facts straight before posting, i said "if q_ball is right and it does charge when the car is off then thats a good thing" and i was wondering how it would charge without the alternator running...

u can get a good cap without displays for <$100

i spent $90 on a century battery, $80 on a cap thts $170 all up and $100 cheaper than just a battery, it seemed to work for me.
i think yellow tops are a great way to go if u got the money but it seems i got the same results with a cheaper alternative... the biggest difference i noticed was my sub, gains are running higher with no distorion and dimming is still there a lil bit but greatly improved considering gains are alot higher...
