Wiring help 4-channel amp (diagram attached)

[REVNU]

So after reading my PPI a404.2 manual I still couldn't find out if wiring up two 4-ohm Component sets will get me 2-ohms Stereo. Below is my diagram. Will that give me 2ohms from the 4-channel amp?

If this helps or makes any sense, there is a button that says "FRONT/REAR" Combined". The manual says this:

"On the left side panel of 4-channel amps is a "2/4 way" switch. If both "Input-1" and "Input-2" are to receive the same input signal, place the "2/4 way" witch in the ON position. This will parallel the inputs together internally in the amp. In this mode, either set of inputs may be used."

Does this mean it will parallel my 4 ohm speakers into 2 ohms? If so, is the way I have it wired correct? Any help will be greatly appreciated!

wiring like you have pictured will have each channel of the amp running at 4 ohms. you would have to put both comp sets on one channel to achieve that 2 ohm load.

I think that amp is only stable at 4 ohms bridged. The way you have it in the picture should be getting 200w to each component pair.

yep, the way you have it now, the speakers are gettin 200w, but its a MONO signal, not a STEREO signal.

connecting the right channel to the front or rear inputs and the left channel to the other would give stereo.

I think that amp is only stable at 4 ohms bridged. The way you have it in the picture should be getting 200w to each component pair.

According to the specs in the manual the amp is stable at:

50w x 4 @ 4 ohms Stereo

100w x 4 @ 2 ohms Stereo

200w x 2 @ 4 ohms Bridged Mono

So you are correct. Problem is that the 200w is MONO, not stereo. So I need to get it to 100w @ 2 ohms without bridging, with a set of 4 ohm components, if that's even possible using all 4-channels. Thanks guys, this is helping, but I am still unsure if this is possible or exactly how to wire it.

When you say ONE CHANNEL, do you mean the LEFT or RIGHT channel, or FRONT or REAR channel?

Just make your front your left channel and your rear your right channel. and you'll have stereo sound.

Well, that sounds simple enough. I'll try that and mess the the MAGIC BLUE BUTTON. and see how that goes. Hopefully it give me my 100 watts.

You will get 200 watts to each component pair. Meaning the right side will get 200watts and the left side will get 200watts and it will be stereo.
