Would it be a good idea to install a capacitor in the hood of a car? I would think no, but if I was able to place it by the battery in a weather/water proof box? Also, people who have amps installed, anyone use an amp rack? Did you build your own, if so, any pix or ideas on one? THX!

 

caps should be near the amp... not the batttery.

 

Exactly.

Building an amp rack is really up to your imagination. I wish we had a picture thread. :thinking:

 

I was hoping the save some cargo space by placing the capacitor elsewhere. Anyways, is it wise to hook up the dvd reciever and sub to the capacitor as well or is it really just for the amp?

Oh yes, anyone have design ideas or pix of their amp rack?

 

The cap is for the subwoofer amp.

 

If you plug a speaker into a constant power supply, I.E. a subwoofer to a cap, it's going to go crazy. It'll play whatever tone is equivalant to the frequency of the electricity moving through there, but at full excursion until the thing blows.

 

Meaning it is a BIG :nono: Make sure the speakers go through an amp and not directly to your battery or cap.

The cap goes to the sub amp, no where else.

 

Thanks guys... I did not know that. So I am guessing that a 1 farad should be more than enough for a 4 channel 960watt max amp? Also, would anyone recommend an optima battery for this kind of setup? It seems that optima batteries have gone up in prices lately; over 200 in some places (locally).

 

What kind of car?
What is in the system?
What is the condition of the current electrical system?

 

It's Optima, and I love them. I've had a blue top (34m deep cycle marine battery, 120 minute reserve) for something like 4 years or something. It's survived getting chucked out of the car in a crash and flew down a hill, getting drained all the time, starts on damn near no juice, and an 800w system with no capacitor. throughout that entire time. So yeah, get a blue or yellow top. Yellow is made for stereos, but blue works extremely well too and looks cooler. And I think the reserve is WWWAAAAAYYYY underrated.

Rule of thumb is 1 farad per 1,000 watts, but wait for B00gers' opinon, he knows more than I do. (and I don't know why he's asking one of those questions, and I can only assume on another of them, lol)
