The Best Amp for the money

The following review is for JX400/4D, which is a part of the bundle you are viewing.

Bought this Amp because my brother has one and I'm familiar with the name and product . I paired it with component JBL speakers and it sounds incredible. Only downside is a little Engine noise that I need to filter out . Amp has a lot of power !

Lots of Power for little $$

The following review is for JX400/4D, which is a part of the bundle you are viewing.

JL Audio did it again with the JX400. Small size and cost yet BIG power. I have this amp running my 2 sets of Kicker Components and they are rocking!
