I am currently in the process of creating a car for competition purposes. I am planning on buying 3 or 4 Alpine 10" Type X series subwoofers...however...I need some help on choosing and amplifier and powering options. I need the advice of the big dawgs..please. Main concerns are what amplifiers? and how to upgrade powering system? They do not make upgraded alternators so other than a new battery and bat-cap I dont know what else to do. Please post back. Thank you for all the help. BTW the subs are dual 4-ohm and 1000w rms a piece. Thanks

I would look harder for an upgraded alternator, try powermaster, High Output alts, or irragi alts, I would bet one of those companies would make one for you.
What organization and classes are you looking at running?    
What made you chose alpine type x subs?     The few I have seen at a pure SPL show have had very bad results.   They just dont have the proper excursion abalities for SPL use.

Yeah, Jeff is right, those Type-X's can be made to sound good and hit deep, BUT, when there pushed in spl purposes, they almost always bust apart. It's like bringing an Austin martin to a drag race, you'll get smoked (SPL), but if you throw in some curves, you'll win (SQ)
Can you return them?

I have a 2005 Toyota Matrix XR...so the size is somewhat of an issue but with a hatchback the system should sound pretty good. What other suggestions for subs would you offer then? Like I said I need a sub that sounds good in a smaller enclosure but still packs of hell of a punch..hit me back. Thanks

Also for my first competition I will probably be competing in the freestyle category and maybe move up to the street category. Thanks for helping. Also money wise. Im lookin at around 2500 or maybe a little more. Thanks

Make sure you check out Irragi as Dom is the only person that I contacted that was very familiar with the alternator on a newer toyota. They are set up differently then a normal alternator for some reason and he is the only one I found that could make a replacement that was a direct bolt on,
