if i am pushing 2 Rockford p3's and a hifonics brz1700 at 1000 watts at 1 ohms with a 1 Faraday capacitor. should i upgrade my electrical system or will the rx8 be stable with just the stock stuff?

do you mean the battery, alternator, what?

yea either one of those two ... do i really need them or will i i be fine with what i have

How many amps does this amp pull? (add up the fuses on the amp(s)).

Also, the cap is useless, If you want extra power for your bass get a bigger battery or a bigger alt or add a matching battery to the trunk. Or you could do all 3 depending on what your ultimate goal is.

Like I said in your other post, look into the "Big 3 upgrade" as well.

im not sure what that means but this is the amphttp://www.sonicelectronix.com/item_23547_Hifonics-Brutus-BRZ1700.1D.html

I would at bear minimum upgrade the battery and perform the big 3 upgrade for that amp. It has a 160amp rating.

I would suggest a 1/0 gauge power wire with about a 250 fuse incase you ever decide to add a high amp. That way the wiring is already there for when/if you ever need it.

Upgrading the alt is going to be a judgement call. The stock alt puts out 100-105 amps, your car needs about 70-80 amps to run properly. From what I've read the electric powersteering draws a lot of juice to function correctly.

Just some stuff to consider.

I don't think cap's are useless at all. They don't provide extra power but they smooth out the power the amp receives so it is a more constant number rather than jumping around. Some people think they help with lights dimming others do not, I think in SLIGHT dimming cases it would be helpful but if your having major dimming then its not going to do very much if anything.

I gave him a good link for the big 3, so hopefully he gets that done.

A cap is just one more thing adding to the stress of the alt. It's not a battery so it does not make it's own power.

So not only does the alt have to power the amp it now has to keep constantly recharging the cap. Even if the cap would help it would only help for a milisec before becoming a burden to the alt.

Not saying your wrong or I'm right... Thats just my opinion I guess.

I agree that a cap is not to be used to make your charging system better, if anything it would probably make it worse if you had bad issues already. It does help keep a steady and constant supply of voltage to the amp though. I dont think it would stress the alt that much because all the alt would be doing is supplying power to the battery and the battery then supplying it to the cap.

I may be thinking incorrectly here but if you don't have a cap and you have your system going full blast it should be creating more of a strain on your battery and probably your alt as well. I think the way capacitors work is they supply the extra electricity that your battery may not be at times of heavy load. I don't think the cap ever gets very low on voltage and then needs a big recharge from the battery so shouldn't it create less strain?

I'm by no means really knowledgeable about caps that is just what I have gathered from reading around, if I am wrong hopefully someone can jump in and say so.
