Ok, thanks for all of the great information so far...Here's what I've come up with:

Phoenix Gold Octane R 5.0 4channel Amp

Polk Audio db104 Subwoofer

POLK Audio db690 6x9s

Ill bridge 2 channels for the amp and put the 6x9s on a 80w channel each.

I plan to use a line converter to get RCA plugs to the am because the stock h/u doesn't have pre-amp outputs. The amp is supposed to have 12db HP / LP variable crossovers and a Low pass level port. Questions:

1) I think that the crossovers will allow me to to send mids and highs to the door speakers and lows to the subs, is this right?

2) Depending on whether I'm right in #1) do I need to put any of the bass blockers and what not on the speakers?

3) What is the Low Pass level Port?

4) When I splice into the line, I assume I want to use the line that the factory 6x9s are on so that I get a much fuller range signal to the amp?

5) How poor of a substitute for a preamp RCA is the line converter?

6) Since I'm sending 80w to the 6x9, do I need to replace the factory speaker wire?

THANKS SOOOOOO MUCH

Doug

Right... if I were you, I'd set the HPF on the speakers at like 80hz, and the LPF on the sub to 80hz.

2) Depending on whether I'm right in #1) do I need to put any of the bass blockers and what not on the speakers?
Nope, it's all in the amp

3) What is the Low Pass level Port?
No f'n clue

4) When I splice into the line, I assume I want to use the line that the factory 6x9s are on so that I get a much fuller range signal to the amp?
Yes, splicing into the factory 6x9 wires would work fine.

5) How poor of a substitute for a preamp RCA is the line converter?
It all depends on the quality of the signal from your factory deck. Most LOC's aren't bad at all qualitywise.

6) Since I'm sending 80w to the 6x9, do I need to replace the factory speaker wire?
I would... 16awg at least.

THANKS SOOOOOO MUCH

Thanks for the answers...they are very helpful. I see you have the Caravan, this system is for a Ram, but my wife has a matching Caravan.
