remote/turn on wire for 2 amps?

**blackdouglas76** · 10-07-2007, 02:12 PM

Hey guys,

1. I have two sups hooked up with a remote wire now. I am adding an amp and two more subs, so how do I get the remote wire to the second sub? Do I have to run a second remote from the HU?

2. Also, would I have to run the second amp ground to the same spot as the first amp ground or can I ground it anywhere?

3. Where my amps are concerned, both are the same, but they do not have outs. How can I make them communicate with audio cables? I know I need Y adapters, but how are they plugged up? Do I need one or two adapters?

Thanks to anyone who can give me a detailed response to these questions, after I understand this, I can hook everything up.

Thanks,
JIM

1) Remote wires carry negligable current. You can connect them all daisy-chain like no problem. So you dont need to run a whole different wire from the HU.

2) Nobody knows. They will both work, but some people swear by grounding it all to the same point, some people swear by grounding it the shortest distance. Do 1 and if it has a ground loop, try the other.

3) What do you mean your amp has no outs?! An amp takes an input, power source, and output. All amps have an output, it is how a transistor works...

And where will the CarPC be going? Did you realize this site is for CarPC people?

Well, I mean that it only has one right (red) and left (white) audio channel. These are the inputs for the HU. In order to send audio signal out from one, I would have to use a Y adapter, I just don't really know how. I am assuming that I would have to have 2 y adaps and 2 audio cables in all?

Depends on how close the amps are to eachother. If you already have a pair of RCAs run back to one amp, and the amps are close enough to eachother, just get two splitters, unplug the RCA cables from the old amp, and plug a splitter into each RCA cable. Then plug one side of each splitter int each amp. One cable from the red pair goes to each amp, and one from the white pair to each. Use extension cables if necessary.

I wouldnt run the splitter as it will cut the signal going to each amp in half. Instead I would suggest using something such as a Audiocontrol 6XS to split the signal and amplify it. You can take your original pair of RCA's from your head unit, plug it into the 6XS and then have front (high/mid), rear, and sub outs with adjustable pre-amp voltage... checkout www.audiocontrol.com They have other equipment that may also meet your need. I currently own an 6XS and enjoy it very much.

It's a little late, and my electrical theory part of my brain has already fallen asleep. But how do you figure it will cut the power in half? Depending on his preamp levels that he's currently got, I'm going to guess that it's between 2v-4v. Splitting the signal does NOT cut voltage in half. The only way it is possible to cause a voltage drop if the amperage draw on whatever preamp decice he is using, is becomes higher than what it can produce. But we're talking miliamps of draw here. I don't see splitting the signal between two amplifiers putting a significant strain on the preamp, and "sucking it dry". Especially if he's using line drivers.

And so what if he drops his preamp power half a volt (if it even did in fact happen)? He should still have ample power to get a good clean signal to his amplifiers.

Maybe I'm wrong, but I've NEVER had problems splitting an input signal.

At any rate, spending $200 on a crossover to split a signal to two seperate amps is a bit silly. If he actually needs that, then fine. But in the case of just splitting a signal to add more subs, esentially all he would be paying for would be the line-driver aspect of it, and those can be had for WELL under $50...
