Summary: While the speakers are just ok, the box is way too small for these subs for it being a ported box. This is like 3/4 of a cubic foot. these subs need at least 1 to 1 1/4 of a cubic foot a piece to sound good.

Summary: Checked out reviews on this and from the sounds of it, for the price it was a great deal.

The only problem i have is the sub makes a popping sound when i turn my car on and off (like when you turn on computer speakers) and i think its because the front unit(deck) i have is giving too much power to turn the sub on and off, through the remote wire, causing it to...
