Crazy system requirments

[[JUDGE]]

Hey guys im going all out with my audio system obviously, speakers everywhere, subs, amps, got half of it all already...and my mate was saying im gonne need another battery and a better alternator, Can people sum it all up to me in good old english for a kinda newish person to audio.

[StoneX]

What equipment will you be running... It's highly unlikely you'll need a second battery or alternator upgrade unless you're pulling ridiculous amounts of current. I'm running 2800Wrms worth of amps with just an upgraded battery.

[J_D]

Unless you have a full on db drag system you shouldnt need a new alternator but it might pay to get a deep cycle battery. I used to run a system with about 1500 watts and only got a decent battery for it and never had problems with battery charging. If you do want a better alternator you might be able to get one off a VP that had all electrics as these should have a higher charging capacity.

[Tasmaniak]

Define all out.

What equipment you have and what you are adding to it.

[[JUDGE]]

im talking about a

New pioneer deck (bluetooth on its way)
Atm one Kenwood amp, 2 more coming
6" 220W and 4" 100W speakers
6" 220W splits and 4" 150W splits
2 12" cadence subs 1400W
soon to be getting 6X9's,6.5" and maybe 10" speakers..

J_D... dB Drag isn't conducted with cars running so an upgraded alternator is pretty pointless. You'd want LOTS of batteries for SPL and standard alternator or external battery charger between runs.

With that gear, you won't need a second battery or new alternator. Get it all installed properly(this means upgraded ground wires from the chassis to the battery) and see if you have any headlight dimming issues, then you may want to invest in, dare I say it, a capacitor.

I only upgraded my battery to a deep cycle (Optima Yellow Top) because I occasionally run my stereo with my car off and wanted a battery that would last longer than stock and not be damaged by repeated discharge. When driving I do get headlight dimming at extremely high volumes but it doesn't bother me.

Well thats alright then, how much did one of those deep cycle batteries set you back? How much r they and where abouts can i grab one?

[[JUDGE]]

quotes??? ..also if i dare say id need a capacitor...what would u recomend..i also want another 15" and 12" sub but that wont be till next year..

P.S no idea about capacitors, just had a bit of a read of the capacitors thread, kinda get it, but yea.

[Boonz]

i think those optima deep cycle ones are around about $500-$600.... capacitors pretty much store over 13 volts and keeps the power supply to the amp stable

[StoneX]

The Optima set me back $320, but you can can get Delkor and Exide deep cycle batteries if you're not keen to spend that much. They do the same thing.

I won't recommend any capacitor as I haven't compared them... But generally speaking the more expensive the better, but how much better or worth it, I can't say.

Yeah, the capacitor basically filters any voltage change... It helps keep the voltage level so that your lights don't dim as much or at all. But don't even think about it yet... Wait to see if you have any problems before wasting cash on something you don't need.

[Tasmaniak]

I have 4 x 10F capacitors sitting here going cheap LOL

[[JUDGE]]

lol i dont think ill need one just yet, maybe when my system starts getting really crazy haha, stonex how much are the Delkor and Exide deep cycle batteries , and where can i get one?

[Joe Peeps]

super street = engine on... or extreme class. Not that it matters.

Alternator upgrade will help voltage when your cruising around, but before i did that id upgrade the charge wire to battery (and as stone said the battery to chassis earth, and engine block earth) and run the biggest power cable i could. Your right, you wont need a cap with your proposed system. If you did id be very surprised

Most battery places that stock exide will have the orbital. I think its about $280. Check out the website, it has a list of stockists.
$320 for the YT? from where! i want one!

[daron]

you dont need caps if you run corect wiring
caps are for lazy ppl who dont update power wires

[[JUDGE]]

So basically ill need, a better battery (maybe), upgraded to bigger earth wires, a big power cable for the amp, and how do i upgrade my charge wire for my battery got no idea about that one.

[garfa]

ray: how much for a 10f cap?
also just as a side note: dont bother with a cap under about 6f. not worth the bother.
daron: depends on if your being lazy or really do need sume sustanance from a cap!
vn2nv: your standard battery will be fine. if it stuffs up after upgrading the chassis to batt neg, alt to batt pos and engine block to chassis neg then consider a better batt. as for the pos to amp, get what you need. pretty much figure out all your power in Wrms then ifs its a class ab (2 or 4 channel amp its effiecency is 65% and if its a class d (mono block) its around 80%) multipoly the Wrms total from all pseakers and figure out based on efficency what sort of amps you will be pulling using ohms law (power = volt*amps) and your set to find a fuse and pos cable for the amp/s.

[Tasmaniak]

10F cap dependant upon who it is from will set you back anywhere from $750 to about $1400. These are about $900 a throw. But we aren't using them for car audio. They are being used for an airbag suspension setup. Well....three of them are, the fourth is for the stereo.

[[JUDGE]]

geez they cost this much??...ive decided to remove the 6.5 and 10" speakers from the system idea ...or either give my 6" to my gf and get new 6.5"s..

[Tasmaniak]

not typically. the ones I have have about 10X the typical capacity of a stiffening capacitor.

[kopper69]

Just for general interest, you can buy 2700F caps but they are only rated at about 2.3V.

Caps are still a bit of a mystery to me. I can buy a 2F 5.5V cap, a little bigger than 2x five cent coins, where as a 2F 12V cap is twice the size of a coke can. Whats the go there?

[Tasmaniak]

Apply logic to it and use ohms law.

[Burnout_bro]

i run double the power than you will vp2nv, its far from a crazy system and so is mine, you wont need a deep cycle battery for that sytem yeah one would be nice but in your case its just another sound system, nothing special is needed for yours

[vr_owner]

whats in your system?
id like to one day just for the sake of it run 2 18inch kicker solox subs

[kopper69]

Apply logic to it and use ohms law.

Ohms law has nothing to do with it big fella.

[Sabby]

where would you most likely show off this stereo?
because if its near a power point, u can buy a 40amp regulator for around 300 bux. this will by pass the battery totaly and u can run the system all night.
the only down side is, is that you always need a power point and u gotta change leads to the battery.
