Pretty things make the world go round: and you heard it here first.
Just take the enclosed CP208LG-W3V3 double-sub system from the American audio daddies, JL Audio.
On top of looking damn sexy, the apple in the eye of these two bass-bangers lies in their specially designed box.
It has been constructed and ported with the sole goal of smooth, low-tuning frequency for quality bass.
A good amp capable of 200-500 watts will be good enough to power this beast in your boot, without taking up too much room either. Get it, we say!
