x603

yes thats parallel. basically you're connecting all the + together and the - together. this will cut the ohms in half with 2 speakers.

is that good or bad? Do you want more ohms or less ohms? Ohms is resistance right? So wouldn't less resistance be better?

hey there, i have a xtant 603x (older version, same thing though) and that is 2 ohm stable on the 3rd chan. get two 8's at 4 ohms a piece then wire them to have a 2 ohm load at the amp. then just turn the gain down a bit and you'll be good to go. those subs can more then likely take more power then they are rated at. also a nice sub to look at is the image dynamics subs. i have a dvc 12" image dynamics sub and it works great. OR if you have a little more space to mount a taller sub. look at the new pioneer premier 2000spl (or something like that) line. they have gotten amazing reviews and will sound a lot better then the 2 8w0's and better then my image dynamics sub.

won't 750w rms be overkill for the amp?

if the amp is rated at 2 ohm stable, you should be ok. and yes, u basically double the output since you're cutting the resistance in half. a good idea is to put a capacitor in line close to the amp if ur gonna load it at 2 ohms and crank it. if ur using those 8"ers, i wouldnt worry about it cause u got too much power there as it is. no need to stress ur amp at 2 ohms if its not needed. if u go that route, setup your system so u wont blow them. turn ur gain all the way down and ur radio up. slowly adjust ur gain up and stop before they clip or start to and back it off a hair. this way the chance of blowing them are minimized.

I read about the 2000spl, and I am interested, but it runs at 750w rms, my amp wont put out that much, even at 2ohms. How will it work? Also is the ts-w3004spl any good? Does it matter what capacitor I use?

first off:

you bridge an amp, you wire speakers in parallel/series. you cant bridge speakers.

The w0 series will handle a ton of power more than they're rated for. my friend had a 10w0, we were giving it upwards of 300W, it lasted for 2 years, and it was still working when he replaced it. But I would look into something else other than JL. JL is nice and all, but its overpriced. Check out the mempis PRs, you should be able to pick a 10" up for about $90 right now. A little more than the w0, but its a much nicer woofer. Also, if you want to get stupid loud, the new cerwinvega vmaxes are awesome and need little to no power, just make sure your using a ported/vented box. And a 15" isn't a "waste". Speaking in generalities, a 15" will go lower than a 10"/12"/etc. Look at standard speaker setups: 1" tweeter for highs, 6.5" for mids, 12" for lows. Bigger cone = lower freq. If you want a 15", go for it.
The 2000spls are kickass subs, I used to have a pair, but they are power hungry, figure putting at least 600W to one to get decent output.

forget about a capacitor with that amp. i have a rf 1farrad amp sitting in my room, you just don't need it. Xtant is a very high end product and has a great power managment. the amp runs perfectly at 2 ohms, i believe xtant actually recomends running the 3rd chan at 2 ohm. Just be sure to run 4 gauge power and ground wire and you'll be fine. I think that the 300 watts (probably under-rated) will push that premier sub just fine, i believe a guy on the vette forums is running his around 300 watts with no issues. If you are afraid of underpowering that sub (which i dont think you will be) then i suggest going with the ID like i have. it sounds amazing and it's really tight.
