Since I have some equipment installed in different car, I went to the JBL sub indeed ran with good but not above-average expectations. The sub was very very excited what makes a Mac Audio monoblock in conjunction with a Pioneer control unit installed and I'm really this sub for a print! Of course he has his weight and takes a lot of space, but for a normal end user He highly recommended! he still enters what will be some operating hours in availing the better! a sub is sounded as expected can not be beat in terms of price performance ratio.
