SVC + DVC with 2 Channel question

[TheBlackSheep 10+ year member]

Alright, here's the problem:

My setup right now is a Pioneer DEH-3500P HU with 2 Infinity Reference 4602CFP's in the doors (nice tweeters for the price), stock 6x9's in the back (The car is a 98 Sunfire GT Conv), a CV HED 1202 and an Eclipse something or other in a box in the trunk, running off of a Jensen xa2250 amp. I blew the matching CV being an idiot and I got the Eclipse for free (Even though it's been broken and re-sealed (crappily I might add, but I didn't do it).

What you need to know:

The CV is a 12" DVC sub: Each coil is rated at 125W RMS / 4 ohm; so, total is 250w RMS for the sub, 600W Max

The Eclipse is a 12" SVC sub: Rated at 175W RMS 350W/Peak

The Jensen delivers power (as printed by Jensen) (Two channel amp): 125W x 2 @ 4 ohm - 175W x 2 @ 2 ohm - 350W x 1 (Bridged) @ 4 ohm

First of all, is running a DVC sub and a SVC soil a bad idea in the first place? As far as I know, they don't pose a problem (they've been running fine together since I put them in).

Second, my main question, is how to wire these for the best setup? Right now, if I'm correct, I've got the coils wired in parallel on the CV (8 ohm load), and so if I'm right, the CV is getting 62.5W while the Eclipse is getting 125W (And the crappier speaker definitely doesn't need more wattage than the good'n). This is assuming that each channel is rated at four ohms.

My theory (I've been pondering this for two days, decided I should get some help from you guys) is that if I wire the DVC in parallel (2 ohm load), that should theoretically give my dvc 250W (if this was power given at 4 ohms), or 175W (Which is better than 62.5 anyday) at 2 ohms.

Basically, the question is...If I'm running a two channel amp with different

impedances on each channel, how should the amp perform? If I've got a 2 ohm load on one, and a 4 ohm on the other, will the amp given each channel power associated with the rating, or will they meet somewhere in the middle?

Depending on the answer, the second question is this; with the power outputs I could be getting (either wiring the DVC in series or parallel), am I better off sticking with both subs or running each channel to a coil on the DVC and run it alone?

I need help guys!

run one sub or the other. Choose wisely. Post smaller.

So running both subs isn't a good idea? My box fits two twelves, so if I choose to run just one, should I get another enclosure and just have the 1 12" in a box by itself?

yes.

run one or the other, not too many amps are going to live one output in 2ohms, and the other in 4. You may let the smoke out of your amp like you have it.

In an attempt to do as you guys told me, turns out a 2nd tinsel wire was unconnected to the terminal on the CV. As far as I'm concerned, CV isn't a good speaker. The Eclipse (the semi-busted one I got for free) is the only one working properly, I was wrong, it's 170W RMS and 350W Max. Since it's the only one running, any ideas for wiring for it?

Also, I need recommendations for replacement subs. I'm trying to remain low budget, preferably something that'll perform well with the amp I've got.
