Matt thanks for your response. I have a couple of questions though...

-The amp requires a separate set of power wires ran straight from a high-current source such as the output of your battery selector, or straight to a battery. This will of course require large diameter cabling to handle the extra current that the amplifier demands. I'd say somewhere around #8 wire at least, depending on the length. Be sure that the positive lead is fused as close to the source as possible.
I simply used the wiring from the old radio. It looks to be #8 and has the built in 5 Amp fuse in the fuse block in the engine compartment. So I assumed I could run both the head and the amp off of this, when I hooked them up however the head powered on but the amp did not...which is why I thought it was bad.

--The amp requires a separate switched "turn on" wire from the head unit. It will provide the amplifier with 12 volts at very low current to let the amp know it needs to power up. It is connected to the "remote" terminal on your amplifier. This is typically the blue/white wire coming out of your head unit.
.
Yes I connected this lead...also tried the amp with out it,

--Your Sony Marine CDXM30 has "line level" outputs. These should be employed when hooking up to your amplifier. They are on RCA terminals on the head unit, and would require four of them to connect to the four RCA line level inputs on your Pyle (labeled as "LOW INPUT" on your amp, item #4).
Yes this is how I had it wired, but no power to the amp, so no sound.

-As for your stereo powering up when you power on the battery selector, that's probably the default way of operation, and I don't know that you can do anything to fix that other than hooking the yellow wire on your head unit to a separate accessory switch and using that switch when you wish to turn on the stereo. Keep in mind that if the battery select switch removes power from the red wire on the stereo when it's switched off, you'll have to reset the clock, audio settings, and station presets every time you switch the power off.
That's ok I think, never listen to the radio anyhow.nor do I use the clock or change any of the settings. I would think any marine head unit would be this way since boats can sit for weeks without being started.

-The radio cutting off when volume is increased is indicative of a supply that cannot source enough current. My guess is that there is a corroded connection to a fuse, a corroded wire, or a corroded Molex connector somewhere along the line. Hope this helps.
Yes I left the head in, and will be checking the wiring more the next time I get to bring her back home. But that seems very difficult looking at how the wiring is on a boat...no real easy access to the wires. This might be over my head, we'l see.
Thanks again.
