So, as it stands today, I'm an old SOB.
I've got a 2002 Chevy Silverado Crewcab HD that I have recently upgraded the head unit to a Kenwood KDC-BT952HD and I put 4 Polk Audio Dxi650's in the doors.
I am still needing some bass, but I don't need it to blow my doors out or impregnate the neighbors cat.
I'm looking at a box from caraudiofactory.com (unless that's a REALLY bad idea, please let me know...) that will hold a single 10 or 12.
Fits 2001- 2007 Chevy Crew Cab HD (Heavy Duty)
1-12''or 1-10'' or1-8'' Speaker
Fits under the back seat the passenger side.
Down Firing System
Air Volume .78 Cubic Feet
Mounting Depth 6.5''
Material 5/8'' M.D.F
Speaker terminal is included
Magnet diameter not more than 5''
1.5'' clearance under the box
Life time Warranty.
It seems the best from my really old school opinion. My thoughts are that one 10" or 12", sealed in .78CF would sound better than two 10's w/ .55CF (my other box choice was from subthump.com and offers the ability to run 2 10's)
I'm looking at all these numbers and volumes and I'm getting numb.
I just want it to sound clear and fill the lows.
I don't really want to spend more than $400 (Amp for the 6.5's in the doors, amp for sub, box for sub and sub)... I can stretch that but not a whole lot. The box for the single sub is $89.
If it helps, I mostly listen to classic rock, some alt rock, and a VERY small amount of rap.
Thanks for any help and sorry for the book
