Need Some Advice

[Penny727]

Hey,

I am a semi-noob to car audio, but I've been lurking around SMD forums for a while now. I own a 1994 Jeep Wrangler. I am looking to install a sub. I have a few questions:

1. What would be a good sub/amp combo around $300-400?

• I've been looking at a Sundown Sa-8 or a 10" Type R
  

2. I was wondering about what kind of box would fit and sound good (ported/sealed). I plan to mount the box in the trunk area. The dimensions of a box can be around 30 inches wide, 10.5 inches deep, and around 12 inches tall for front height and about 17 inches tall for a rear height.
