The top is implementing the same as any sytem but the power of the crown-amplified system, 2 x 660W sub this in every breath away and you can ask him. There are "under the hood!" The least that will weight 54 pounds but it handles well with its wheels fitted as standard.
There used to like.
As for the price it is very good when compared separately purchased a MP418 + 1 CROWN AMP 2x500W CE.
Re-election and 4 years since I change on average every year.
