Installing some coaxials.. Not sure the best route to go.

[Plutoman 10+ year member]

Only problem I'll address here is the simple wiring issues.

I've got my amplifier, it's a 4 way amplifier, that puts out 115 RMS @ 8 ohms to each the left and the right. I'm running two Kenwood 6982IE 6x9 coaxials, rated for 90 RMS each, off the left side right now - speakers are 4 ohms. The right side doesn't work well, it gets fuzzy and frequently cuts out - separate problem I'll look into fixing later. Now, based off this left side alone, I'm wanting to run two infinity 6.5" coaxials in my front, each rated to 60 RMS. Each has a 2 ohm impedance.

Should I run these off the same channel here, and would that get me enough power? Or, alternatively - I can run these front two off the head unit. Which is listed at putting out 23 RMS (Alpine CDM 9803, fairly old, but good and reliable), but I'm not sure at the resistance for its output, or if its regulated. Or if I could possibly bridge that - I know its not recommended as it'll burn up newer HU's, but I've also heard older ones might be able to do this.

And I'm not looking for any ability to fade left/right/front/rear, I just want a clear balanced sound. How should I wire this here?

you won't get balanced sound with what you have.

What amp do you have that puts out 115 @ 8?! That's pretty hectic.

Anyway, if you wire them in series (one negative to the positive, then the remaining positive / negative hook up to positive / negative rails) to achieve a 4-ohm load. Either way, is it your amp that's getting fuzzy, or is it the speaker?

Amplifier's right side of channels is fuzzy. It's an old home audio amplifier, rigged up with a DC inverter. Crude, pulls massive amounts of current, but it works. And my budget consists of the money in my wallet ($11), which is why I'm going with what I already own.

i would just say run the speakers off the head unit and save up for an amp.

or if keeping the amp run the 6.5s off the stereo and leave the 6x9s on the amp but wire them in series like stated above^^
