I did that, and actually had them turned up only about 1/4 turn and still after a short time they just started sounding like distortion.

Your speakers could be blown plug the same amp your having problems with (your highs) up to some different speakers and see if you have the same problem

Yes I do know that much, everything was hooked up correctly in theory, but after a while of playing the highs would start to sound like CRAP, distorting out like an mis-tuned radio station

Sounds to me if you have the gains adjusted properly and it starts sounding bad after it warms up, it's simply a crappy amplifier going into overload or perhaps even thermal run away.  It's Pyle, so what do you expect?  I recommend trying a better amplifier.

DYon,,,, that is what my thought was, but it was sitting around so I thought I'd give it a try, what is "thermal run away"?

also it says that the max current draw is 15 amps on the amp, so I don't think it is a power supply issue with the battery or alternator, probably just crappy circutry in a crappy amp,,, ya think?

Still walkin......the speakers sound fine when connected through the deck, so I do not think they are blown

Thermal run-away is when a transistor gets too hot and goes into a nearly uncontrolled conduction state.  It basically operates like it has positive feedback, operating at max output (and in an audio system, max distortion) as soon as it begins conducting and eventually it simply fails.  It happens sometimes with cheaper components or poorly designed systems, or sometimes simply due to age.

Here is what I am going to do, please advise, I have the

2004 Sonata

110amp alt

1 battery w, 2 each 8 gauge runs to the trunk with 50amp fuses

TMA 500.1 (4 each 15amp fuses) running 2 subs at 2 ohm (this is existing and have had no problems)

TMA 320.4 (2ea 30amp fuses) running 2each Pioneer 6 1/2" (4way) and 2 each Pioneer 6x9 (5 way), these are 4 ohm speakers and the amp puts out 60x4 at 4 ohms

so my total power will be only 740 watts

Can I get away without doing the big 3 right now? (it appears beyond MY doing)

Do I need to upgrade to 1 each 2 gauge with a dist block or 2 each 4 gauge runs or will the 2 8 gauge be sufficient?

Just do a single 4ga run with a distro block. No you don't need to do the big 3, though on any system it doesn't hurt to do it anyways.
