this will never ever work WHY?

Ok guys this is first post and I think you in for it.

WHAT I HAVE

1. 98' Tahoe

2. Eclipse Head Unit

3. Phoenix Gold TI 575.4 running 2 sets of MB quart 6.5's

4. Phoenix Gold TI 400.2 Running 1 12" PWD Quart Just got this

5. 1 Farad cap

6. Sealed RED TOP Battery 0 gauge wire.

I already have door speakers set up and running. I need to set up the SUB, AMP, and CAP.

?

1. Should I use the cap for both amps or Just the sub amp?

2. Should I split the power wire with 2 blocks with 2 outlets or just 1 with 4 outlets?

3. Can I tap into the singnal wire to turn on both amps?

4. Should I ground the cap to the same spot under the rear seat were the 575.4 is grounded useing a block. Or sould I just ground the cap to the rear cargo area were the sub will be?

5. The CAP instructions say don't use blocks with fuses. Just a fuse by the battery is this true?

Hope you can help I will have pics soon. Thanks //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

answers to your questions:

1-just the sub amp.

2-1 with 4.

3-if you mean one remote turn on lead jumped from one amp to the other... yes.

4-different schools of thought but i think either will be fine.

5-sorry... not familiar with CAP installations... yet!

Imral ??

I've seen your install online. It's a pretty nice setup. Did you say you do NOT have a cap? Your system could really benefit from one. Shame on you !! Go get one man.

In another note....while it's true bass frequencies are the most power hungry and hardest to reproduce, all amps no matter what they are powering can benefit from a cap. With that in mind "free style" I would put the cap in-line before any amp. Like run your 1/0 gauge in and out of your cap and then into your block. That way, any amp that needs a little juice will have it at its disposal.

You want to put the cap as close to the amp as possible with no fuses between the cap and the amp. Keep all wires from the cap to amp really short. You can ground the cap anywhere with a good connection. I would keep it as short as possible too. When you first hook up the cap charge it through a 12V light bulb when the light goes out/dims it is charged then you can hook it up to where it needs to be mounted.

The cap is not needed on the amp which is going to run your other speakers just the sub amp.

A capacitor is supposed to be between the battery and the distribution block. If there were to be a short AFTER the cap it would "fry" your amplifier and maybe something else. A cap can do as much damage as your battery could in the event of a short. So a fuse between the cap and the amps IS the safest way to go and you won't even be able to tell the difference between the 2 connections. Just remember, your equipment will do you no good if its fried.

If you keep the power wire between the amp and the cap as short as possible there isn't a need for a fuse. If you don't have a cap with a fuse after it and you short it u will pull a really nice spark but that is touching it to ground. The amp already has fuses to protect it so why would you put a fuse between the cap and the amp . The cap only has a fraction of the power in it as compared to the battery. The only reason there is an inline fuse close to the battery is to protect the battery not your amps. The amps fuses are meant to protect them. Most capacitors probally wouldn't have enough juice in them to even blow a 30amp if dead shorted to ground. Note: I have never tested this!! (not recommended). So why put in a fuse that is increasing the resistance of the power wire feeding the amp. Plus why do cap. Man. say not to put in a fuse?

I don't have any capacitors in my system other than the one's inside the amplifiers themselves. My system sounds just fine. With the proper electrical system and wiring. You really don't need to have cap's. My lights never dim. I can run the AC, the stereo, and headlights all at the same time with no problem.

And according to most of the capacitors I have ever installed. You are supposed to install them as close to the amp as possible. And you can use them with other amps, besides your sub amp. But they really don't need it //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
