Battery/Amp compartment pics?

How so? What makes the PPI amp any different than another bridged 2 channel?

I think he's talking about regular amps vs the few that can sum mono...

It was talked about a little in another thread. I sort of understand it, lol.

An amp like the JL 750/1 is truly a mono amp, so question there. An like the Wet Sounds SD-2 and Syn-2/Syn-DX2 are, are their core, 2 chnl stereo amp, same as the Arc KS600.2 and KS300.2. But even then, I still run them in mono for a tower setup. The Syn-4/DX4, SD-4 and SD-6 can be setup to run a pair of tower speakers in stereo, but again, I prefer to run them mono. Not many The SD-6 will also allow for bridged mono or stereo. Not many amps out there that will let you do with a pair of tower setups like these high end amp. Theres WAY more to it than just wattage.

At best, an amp like the PPi900.4, polk 4000.4, exile xm15.4 and xm30.2, Wet Sounds HT4, kicker KXM400.4 and KXM400.2 will let you run stereo, and thats if you bridge and configure the RCAs properly on the 4 chnls.

Theres nothing wrong with stereo on a tower setup, but as been noted, when off axis, like surfing, you are getting most of your music from that one speaker thats closest to you. In a stereo setup, you are missing some content. Mono lets you get it all. A high end that runs mono properly, can make a tower setup just that much better sounding.

And actually he explained it to me even better in a PM. I followed his advice and used RCAs slitters to feed the signal to my amps.

This is where the amp combines the left and right signal on the input side, and sends a mono signal to the pod. A simple 2 chnl stereo like the PPi and most others, cant sum the signal. This means the left and right chnls are meeting at the voice coils. This doesnt sound good at all.

This is ok on a sub-woofer as we arnt going to hear this clash of chnls at woofers voice coil, we you can with a full-range speaker. This is where a higher end amp like the wet sound Syn and SD series are so valuable, also amps like the Arc KS series. They allow for that full-range summed mono signal

Now, there is one way to configure the RCAs with your dual amp setup that will be decent, but still not as clean as something like the Syn-4/Syn-DX-4, SD-4, Arc KS-300.4 or JL MHD750/1. Split the RCA and plug both rights into the left and right of one 600.2 and take the left two and plug them into the left and right of the 2nd 600.2.

This allows the amp to make full power since both chnls are fed, but each pod is receiving either a left or a right, rather than each pod receiving a left and a right that mix at the voice coil.
