[crunch5868 10+ year member]

ok so what kind of batteries should i look into? i looked at some yellowtops,etc but i dont know what exactly to look for.

stinger spv batts...btw H.O alt is the only way to go imo.

 

[crunch5868 10+ year member]

what does H.O alt mean. I would much rather go with a new alt but i cant find one for a volvo, the highest one ive seen was 120amps. whats stock on a car ?

ho - high output email ohiogen or excessive amperage there are tons of companys out there

No need for a new alternator. Add an extra battery group 31 deep cycle and upgrade your charge wires to 1/0. The alternator just increases your battery charging capacity, your batteries will be powering your amp not your alternator directly.

check out the powermaster batts

gonna want 1/0 wire everywhere and biggest batt u can fit under the hood

5100 should fit, thats the smallest battery and a d925 in the back. im pretty sure all you do is run 1/0 power and grd from the battery under the hood to the rear battery and fuse the power wire like u would your amp power wire. and then run power and grd from the rear battery to the amp with a fuse on the power wire again

Isn't your alternator providing the juice from ~12.8 to ~14.4v when the vehicle is running? He might need a H.O. alt if he wants to stay above the 13v mark while the vehicle is running.

i just want my car to have enough power when these things are bangin. i dont want my lights dimming and stuff... Id rather the alt. because its simpler but w/e is best im all ears

its audioque, ofcourse your do //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Wrong. Your battery is used as reserve power. Your alternator is what makes your car run and if the demand for the alternator becomes too great then the reserve current stored in the battery is discharged. This is why your car will be at battery float voltage whenever your alternator is struggling to keep up with a load.

im pulling around 500a of draw right now and i have a stock alt (140) with a red top under the hood and 2 yellows in the rear. so you should be fine with 1 good battery under the hood and a powermaster or my bro has a audio force 1100 that he is selln. either or jus get a big bat for in the rear and you will be fine

i know this is a little off topic but will a 300 amp fuse work for the aq2200d or is that too big? i have a 300a fuse right now.

So you think that the current draw from the system is constant? You also think that the alt can increase output instantaeously in response to a change in demand? You think that the battery only provides current when the voltage drops below 12.6V? You think that they make an alt big enough to supply the current demands of a large system play dynamic music at very high volume?

Man it must be nice in your little dream world.

AVERAGE current draw. That's all the alt needs to provide. Transients will be handled by the battery(ies) every time regardless of how big the alt is because the regulator simply cannot react fast enough to up the current supply. If you use a bank of batteries, none of them ever gets deeply discharged and you're really just replacing the skin charge instead of the core charge. The bigger the battery bank the more current you can draw before the voltage begins to sag.

For that amp, two good batteries should be plenty. Your wiring is going to be very important also. Upgrading the alt isn't going to really do anything and you'll still need the batteries. The place for an upgraded alt is playing long tones. that actully creates a large average current draw where the alt can get caught up and actually directly provied current to the equation. Otherwise the alt is only refilling the reserve between periods of transient demand.

ok the battery idea makes more sense and also seems cheaper. Im getting an amp wiring kit (kicker 1/0) and with my left overs ill do the big 3, and strap a new battery in the back. my front battery is fairly new so hopefully ill be all set with a decent sized one in back. Will i need an isolator for the second batt.? how do i wire this up.

anyone??
