How Do I Bridge A PDX 4.150 Into 2 Channels?
I ran a single set from the front preamp out on my headunit. Do I need to Y the RCAs? 2 lefts to channels 1&2 and 2 rights to channels 3&4.
At the amp, how do I wire? Do I take + from channel 1 and - from channel 2 then do the same on channels 3 (+)and 4 (-)
Also, is the + on top or bottom on the speaker terminal plug at the amp?
And, the instruction manual (Fig.2) shows a ground tha appears to be in addition to the power ground, is that so?
The instruction manual sux.
I'd really appreciate the help.
P.S.
Anyone know where I can find the Pioneer 720 PRS components and at a good price?
Thanks again!

Whether you use Y's or not just depends on how you want to setup the wires. I think it will probably be easier from a speaker wiring perspective to use the Y's but you could also set the switch to 1/2 where it will take the signal for channel 1 and send it to channel 3 and also send 2's to 4.
If you set the amp to the normal 3/4 and use the Y's then put the left on 1+2 and the right on 3+4 what you would do is hook the + speaker wire to the positive of channel 1 and the - speaker wire to the negative of channel 2. Same thing for channels 3 & 4 for the right.
If you use the 1/2 then you would bridge 1 & 3 for left, 2 & 4 for right. Just a question of what you want to do wire-wise.

This was from an independant 3rd party test of the PDX 4.150:
"My single biggest beef with this whole idea is that I found it difficult to determine how to bridge the channel pairs from the instructions. You will connect the positive wire to only the positive side of one connector, and the negative speaker wire to only the negative side of the other connector for the channel pair. But now, which jacks do you plug them into? For the record, the odd channels (1 and 3) will use the positives, but I determined this by finding out which were the active outputs from the amp. It’s not mentioned in the owner’s manual. If you plug yours in and get no output, just reverse your connectors."

But I will absolutely agree.. the manual is complete crap.

Okay - 1st off, thank you for the information.
I will not be using Y connectors, so I'll set the switch to allow 1 and 2 to feed 3 and 4.
If I understand correctly, I should then for example:
When wiring my left side speaker, take the + lead from the speaker and run it to the + on channel 1 and take the - lead from the speaker and wire it to the - on channel 2.
When wiring my right side speaker, take the + lead from the speaker and run it to the + on channel 3 and take the - lead from the speaker and wire it to the - on channel 4.
Is this correct for bridging to 2 channel stereo?
Also, on the amp when I insert the speaker terminal plug, should the + be on top or bottom?
Thank you again, Guys!

If you do that, you'll get mono sound.
Get the Y cables.
Channels 1 + 2 = Left Channel
Channels 3 + 4 = Right Channel
If you put RCA 1 (left) and RCA 2 (right) into channels 1 + 2, then it combines Left and Right RCA, because 1 + 2 is bridged into Left Channel.
And youll have an identical signal in right channel. The combination of both RCAs.
Y Cables are like 3 bucks at Radio shack. Get them.

Ok - So I use the Y splitters.
I connect both lefts to ch 1&2 and both rights to ch 3&4.
Then when wiring my left side speaker, take the + lead from the speaker and run it to the + on channel 1 and take the - lead from the speaker and wire it to the - on channel 2.
When wiring my right side speaker, take the + lead from the speaker and run it to the + on channel 3 and take the - lead from the speaker and wire it to the - on channel 4.
Is this correct for bridged stereo?
P.S.
I found out that it doesn't matter which direction you insert the speaker plug, as long as you insert the proper wire into the proper hole on the plug.

In which position should the input selector switch be?
