Audio/Battery Question

Why...lol, depends on how much in amps your driving, Cap is good to have, again get a Optima Yellow and you'll be fine

Again...what are you running, how much amp's, etc...I play my system LOUD and have a 6 channel JBL at 600 watts...have never even come close to draining.

I know any audiophile will suggest to upgrade the world...Right Zander, Tyler & Waylon...lol

I see a trend..."Optima Yellow Top"

YellowTop Group 75/25 Dual Purpose (Deep Cycle & Starting):

Weight 37.8lbs.
Length 9.38inches
Height 7.75inches
Width 6.81inches

Or

INTERSTATE BATTERY MEGA-TRON PLUS - 85 MONTHS - 700 CCA

Had me thinking Colby...Yellow Top worth the Weight...haha, get it

Cheers man:)...no need

Kidding, of course.

lol

Aw, and here I thought you were just ignoring lovely little Tristan.

Keep in mind with your calcs that music is about 30% duty cycle. Meaning, if you run your 600W flat out, it will only suck about 200W for real (15A).

So it's like leaving your lights on basically.

As far as batteries go, my limited understanding is this:

The tradeoff is between deep cycle and starting amps. A deep cycle has less plate surface area, but thicker plates. The oposite is true for a starting battery...mores surface area but thinner plates (For any given battery package size). The combo batteries are just that, some thin, some thick, or all medium thickness.

Caps help reduce the transient requirements on the power system (Battery and altenator). They are best when mounted really close to the main power device, in this case the pwer amp. This is because of the impedance of longer leads lessens the transient help the cap can give.

It should 'clean up' and base distortion due to lack of supply which can occur in setups with long, small supply wiring to the amp. Another way to look at it is if you buy the big cap, you can tell the guy trying to sell you the 4/0 cable for you amp the big finger, 'cause really you only need #10 (Which will easily pass 30A). This will more than pay for the cap in a longer supply run.

It won't help in your amp-hour energy requirement.

If it was me, I'd stick with the smaller deep cycle battery, and a larger altenator, plus a nice juicy big cap stuck next to the power amp.

1 more thing...if you run this setup, have a really good low impedance ground from the power amp to the head unit. This will prevent ground rise oscillations from occuring.

Yup they're heavy alright. Cake...eat it....you get the idea.

batcaps? Is this a composite word, or are you looking a super(ultra)capacitors?
