Hi everyone, I am new to this site, and reasonably new to car audio, but I am looking to build a killer system. I am trying to decide what subs I would like, and have narrowed it down to a few different brands/models.

I am debating between the following:

MTX 9500 (12 Inch)
Kicker L7 (12 Inch)
RE Audio XXX (12 Inch)
Alpine SWX (12 Inch)
Pioneer Premier (12 Inch)

I could go with a couple of 10s with any of these as well. Either 2 10s or 1 12.

I am looking for a good balance between SPL/SQL, and most importantly quality. I dont want something that will fall apart. Thinking of installing in either a sealed or a slot ported box. Will build with 2 inch MDF. I would appreciate a responsive sub that can be run at around 1000 watts or so. Dont want to have to upgrade alternator etc.

If anyone can comment as to build quality, performance etc. Also approximate required enclosure size as well. I am an industrial designer, and am thinking of doing on of several pretty cool installs.

Finally I am going to run a pioneer deck- anything with USB capability and 5 volt pre-outs. Thinking either MTX, Alpine, or Kicker for amps.
