Howdy guys,

I am trying to figure out something. I want to wire my components up at 2 ohms. My components ( two sets) are all running off of there own channel right now. I can get more power if I run them at 2 ohms. Help a brother out.

Put two 4 ohm speakers in parallel and you'll have a 2 ohm load.

^ like he said, as long as they are both 4 ohms, your fine. I have my fronts and rears wired for parallel until i can get my hands on a good 4 channel...

so I guess I would have to bridge the 2 front channels and run the positive output to the positive on croosover #1 and then to the positive on crossover #2. And the same with the negative, right?

Amp is 50x4 at 4 ohm or 100X4 at 2 ohm. Someone got a wiring diagram?

NO, Parallel would mean both positives together to the positive terminal and both negatives together to the negative terminal.

Let me try to explain. One 4 ohm speaker will get 50 watts. Two 4 ohm speakers in paralell, you'd get 100 watts, but each speaker still has 50 watts.

So, what is it you are trying to accomplish? Are you putting 4 speakers in the front and 2 in the back? or what?

Usually, adding more speakers makes it sound bad, unless they are eq'd and time aligned, like adding pillar speakers for staging.

The only way adding speakers for more volume works, is if they are the exact same speakers, the same distance and direction from the listening position. And it makes the listening position the only place thast works, off axis will sound out of phase and will cancel out different frequencies depending on location. Out of phase distotion hurts ears.

My amp is a 4 channel amp. I have 2 sets of components. So that is 4 mid bass and 4 tweets. Each mid and tweet is running of each channel off of the amp. so each channel is dedicated to each mid and tweet. They are currently running at 4 ohms because they a 4 ohm components. I want to run them at 2 ohms so I can utilize the 100 watts instead of 50 at 4 ohms. Is that a little more clear? Any help is appreciated.

AHAH, Now i get it. I'd suggest the best way to do that would be to run the components active, but you'd need a crossover, unless you have crossovers in the amp or in your head unit.

This is what i'd do with 4 component speaks & a 4 ch amp.

Ch 1 - Left front & rear tweet
Ch 2 - Right front & rear tweet
Ch 3 - Left front & rear mid
Ch 4 - Right front & rear mid.

Of course you wouldn't be able to fade front to back, but it should be loud! and yes, that means you need to run sparate hi/lo wires to each location.

You need to know the crossover point those components were made for, and you need to block the sub frequencies from the components. You have subs right?

I guess I am not really mr Car audio knowledge. I am completely lost. I really appreciate your help but I dont get it sorry. Do you have a diagram or something like that. I noticed that you live in Ajax. I grew up in Ajax. I still work in Pickering but live in Bowmanville. Cool.

anyone?

you can parallel your components to give a 2 Ohm load, but each channel of your amp can only go as low as 2 Ohms and 4 Ohms if you bridge the amp, so you'd have to hook up all the speakers to the front outputs only.
You will still only have 50 watts per speaker, but you'd have another set of channels free for a 3rd set of speakers.
The down side is an increase in distortion, and more overheating of your amp, and no fader.

If that didn't make sense.....hook up both front and rear left positive speaker wires to the left front positive of the amp, front and rear left negative sp wires to the left front neg of the amp, and do the same on the right side. Nothing gets hooked up to the amps rear outputs.....so no....this is a bad idea.
Nice try though, but TANSTAAFL!
