choosing the correct subwoofer

i have been reading alot of post on this forum and decided to join up. it seems like there is alot of knowledge here, so i would like to take advantage of that. i have a '03 tundra ext. cab. the floor pan under the pass. side rear seat has been cut out and a new custom one has been welded in. this has giving me a enclosure area of appox. 1.7 cu. ft. the enclosure is 12" deep on one side and angles upward towards the middle of the truck were it is 7" deep. i have enough width to install 2 10" subs that are average depth (5-6") or a single twelve that could be of a larger depth. my local shop went out of business before the install could be completed, so i am going to research this and finish it myself. i was wanting some advice on what sub or subs would work well for this application. i was thinking a pair of alumapro alchemy 10's or a pair of 10" arc a-r-c- subs. but i could also do a single idmax 12, a single arc flatline twelve or any of the larger "sql" type 12's. there are so many choices and i have heard so few of these higher performance subs that i am not sure which route to take. here are a few other factors that would help to determine what to use. i listen to jazz, hip-hop, rock, heavy-metal, basically any kind of music. my front stage will consists of a focal polykevlar 3-way set (6.5's, 4.5's and tweets) ran though a zapco eq to zapco amps giving 200watts per side to the front. i will be using a zapco amp for my sub(s) as well that is rated at a little over 1,000 watts @ 4 ohm. also i would like to stay at a 4 ohm load on my sub(s) just to ensure that everything stays running cool and clean. i am looking for nice tight bass, but i would like to be able to step it up on bass heavy material and really be able to feel the punch. i would really appreciate any advice you could give

If you are willing to spend "Focal money" don't forget to look at the Morel line.

Your sub amp.... Alpine PDX1.1000. I think you will find some awfully good reviews of that amp on this site Haemphyst is the guy to ask!

And the beauty of the PDX is same power output at 4, or 2 ohms. And tiny little things.  The IDQ subs are sweet, the 12 is 8.50 mounting depth...sounds

like you might have room. ??   10's are 7.5. I would have a pair of those over the single 12. I would utilize a sealed enclosure based on your varied listening.

Don't let the extremely low price fool you.  It'll keep up with any of the subs mentioned thus far in output and SQ.  It just doesn't have the flashy looks that some of the others have, along with a lack of a flashy price.

I dunno - that sub looks awfully nice to me.  I *love* that simple cone and traditional dustcap - that thing is - uhh - "classy"

same here.  everyone i work with thinks i have 2 12s in my car with a bunch of power.  i never showed my system to anyone at work...   an i am honestly only running one L5 10 with a pheonix gold 500.2  so about 500 by one at 2 ohms.  in small sealed enclosure also..  .75 cu.ft.

but on your note  deffinetly check into morel  or audison/ hertz,  i have always likedthe jl 10 w3 for smaller enclosure areas..  awsome response and clarity also..
