Just get a battery. You're not going to pay for good caps.

You have two batteries under the hood which are probably 6 feet or more away from the amps.

The time it takes for the amperage to even get to the amp causes the power to lessen so you really just need another agm near the amps.

But id invest in a "real" alternator from one of the high output distributors who offer for car audio.

get a bank of maxwell supercaps. you can get lucky and find them for under $200 with the bus bars which is a STEAL.

keep in mind caps last 100x longer than batteries and wont lose their value like a battery

5 farads wont make a difference ,i promise you that. one bank of supercaps will change your life though lol theyre awesome if used properly

This advice seems to be what is happening and yes, I'd love to buy a Mechman, Singer...etc but the $140 option is what I went with. Time to order that Kinetic!

Kinetic is a bit expensive for your need.

A simple auto parts store agm can do you wonders.

All those autopart store agms are rebadged batteries and actually are good.

By all means tho spend your money your way //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Electricity moves at virtually the speed of light.

i have two of these https://www.sonicelectronix.com/item_88298_Kinetik-HC2400-BLU.html
supporting 4k and 600 watts of mids, no big 3, stock alt, and an xs group 34 up front.

idle it physically wont drop past 12.6 and @ 1700 rpm+ i see 13.3+ all at full tilt

I found a used one locally for 100 and just ended up buying a new one to match. Don't know why I don't see more people running them. They are very stout.

they are budget friendly

Good price on that size AGM.

$$$... Wouldn't I be better off with a battery in the rear for that price?

Yes

True, but distance and wire size cause voltage loss.

Batteries cant charge fast enough to keep up with current demand.

edit; nvm

i was going to say in ac or dc circuits? but dc technically moves at the speed of light but through each electron pushing the other forward. ac is entirely different

I found one online for $219 shipped... I'll look around at whats available locally but first but what size do I look for to support 2500 RMS and have it mount in the car? Remember that it's already close with the alt upgrade and dual 75's up front, all it takes is a frequency change to 35 hz and up to allow it to catch up then I hit a LOW note again and it draws down to 12V... I mean 32 hz and under notes... of course extra reserve is always a good thing. Thanks in advance!

Just get a group 31

As far as mounting you can get creative.

I made wooden braces for mine.

Look through some build logs to get some ideas.

You was going in the right direction.

I think what you mean. Is discharge rate? Batteries have a much lower discharge rate and will not stabilize charging voltage..
