I have a question about if I install a big system in my car.

I want to install the Pioneer Premier PRS-D2000SPL amplifier which is 4000 watts peak and 2000 watts RMS. I also want to install two of these subs - Pioneer Premier TS-W3002D4
They are 1000 watts RMS and 3500 watts peak.

My question is, will i need to change my battery or alternator to power the amplifier? Or would a capacitor work instead of changing the battery and alternator?

Thanks for whoever helps!

Do you know what size alternator you have on the car?

You going to need at least 4AWG cable....best option is 0AWG which id reccommend.

rvpr4

no i dont know, my car is a 2001 Acura 1.7 EL

and yes 0 awg was reccomened:)

the amp has sixx 40amp fuses so thats 240 amps....does that mean i need a 240 amp alternator? or just a capacitor?

carsey

Have a read of this...Its for a VW golf, but you can substitute the Vw alternator figures for the Amps of your Acura alternator.

The rating should be printed on the side somewhere.

YOu'll need a bigger alternator(higher out put),1 or 0 guage wire and a marine battery(dry cell) instead of a CAP near the amps.

I found an 800 amp battery. Wouldnt this work, correct me if im wrong.

If the car is on, and the battery is 800 amps, one amp is drawing 240 amps and the other is drawing 15 amps so that 255 amps,,

say for example the alternator charges 60 amps, wouldnt the battery styll have power while the car is on beccause:

800 ampps - 255 amps = 545 amps and the alternator charging 60 amps = 605 amps

So overall won't the battery styll be at 605 amps when the car is on? or does the amp continuously suck power from the battery until the alternator can no longer keep up?

This is the battery http://www.sonicelectronix.com/item_...+KHC+800-.html

Power comes from the point of highest potential....so all the power will be coming from the alternator when the engine is running.

is it possible to get a 240+ alternator for my acura 1.7 EL 2001? cuz the amp is 240 amps so i guess that means the alternator needs to be atlease 240 amps right?

what does the big 3 upgrade do and what guage wire do you need?

sorry for all the questions I just really want to install the amp but i dont want it to kill the battery:(

carsey

Personally Id see how your current alternator handles the power you will be giving it.

The big 3 is basically the ground wires to the chassis, alternator to battery and 1 other to replace the factory wiring which may not be the best.

Id say you need minimum 4AWG wire and reccomend 0/1 gauge wire.

rvpr4

oh ok thanks, ill do the big three upgrades and ill replace the stock battery with a better one and try it out,, that wont put anymore strain on the alternator right?

carsey

Well....it will as the engine will be working harder to give the car the currents/amps.

Id try wit the battery in first and see how it goes. Good way to tell is when bass hits, the lights will dim slightly....if they do it alot, you need to upgrade.

rvpr4

oh ok ill put in a better battery and try, i actually changed my mind to getting hifonics amp, its same power but a bit cheaper:P thanks alot for your help!

If the Amp draws the system dead then you would want to use the old battery first to see if so.......

is it possible to get a 1 ohm load with four DVC 4-ohm subwoofers?

i know you cud get a 2 ohm load with two of them, so wat if you do the same with 2 more subs, which will mean 2 ohms coming from two subs and 2 ohms coming from the other 2, then you wire them in parallell which will divide the ohms by 2 which will result in a 1 ohm load. is it possible?

lcurle

come on guys, a battery starts the car the alternator runs the car... Easiest solution would be to add an extra battery because you are over 3000 watts. A standard alternator is anywhere between 60-120 amps (maybe more these days) You can get a high output, or even dual alternators, but your stereo is to small to warrant a second alternator. My advice, run 0 guage to a battery in the back, make is at least 900 amps if you can (1/3 of total power or closer) From there run the 0 into the amp if it can accept it, otherwise go with 2 AWG, make your ground as short as possible and the same if not bigger size then the power wire.

Google "Ohms Law" btw.

okay whatever, im just gunna stick with the 2 subs i have right now which are 800 watts RMS total, and get the kenwood 1800/900 peak/rms monoblock amp. I'm still gunna do the big 3 upgrade no matter what because I heard its good for your cars electrical system and makes it run smoother and at its best. And when I'm ready to upgrade again , ill get a better battery, and if i styll have problems ill get a HO alt..

i heard adding extra batteries is bad unless your running yur system with the vehicle off or have a good alternator. then again its probably better than having capacitors

I found this battery http://www.sonicelectronix.com/item_...KHC+2400-.html

can power cells be used to start your car like a regular battery? or does it just run to the amp and you put it in your trunk.?
