I personally would go with kicker...I guess I just like the looks though!
in other words, if you have the $$$ for a XXX, dont power it with sh!t...i.e. MTX
MTX makes good solid powerful amps, have been doing do for years
there is someone on TP that is running a XXX 15 and the Orion 2500D, and is very happy but I cant remember who it isx2 //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif
Anyways, http://www.ikesound.com used to have some refurb'd Orion 2500D's for $500. Helluva deal if you have the $$ to spend. Little more than you would need for a single XXX, but it'd work fine if you use your head.
