hey how is everyone? im fine other than being on strike at work!!! i work at a shipyard in pascagula ms. (us). anyway should be going back soon ive been studying up on some things, because im not as knowledge that alot of you guys have, but getting better lol. cant make up my mind between either the 15's apx or the mt's. i have decided on the amps, two rockford fosgates t3000 1bd. because they are true watts and under rated! and not as much distortion. im going to get the big 3 upgrade and another alternator. and a few batteries, the box not sure about will have to find someone who can build one for me and tune it also. this is all going in a 96 nissan pickem up truck ex cab, is it possible to maybe get 2 18's of either type in there with the right air space? and how to do the ports??? are these amps good for these subs, the amps can run 1ohm stable. no daily just #s would love to see 150???!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!s orry so long just very eager! later guys thanks again for the help

Well, I am not familiar with those two subwoofers that you listed but as long as you are willing to throw away the whole extended part of your truck I am sure fitting two 18's won't be much of a problem. And if your getting extra batteries I assume you are not competing in any street class so you might as well throw out the back seats which will give ya even more room.

Well since you only got 3k per sub the APXs would probaly get louder, but if you had more power the MTs would be a better choice.
