I have a JL Audio 10W6 in a box that is vented. It is being powered by a 250/1 JL Audio amp which is the recommended amp for this sub it is more than enough to power it. This sub is in my 04 Tahoe. I have had it for about 6 months and it has been great really hits hard. the only reason im selling it is because i want to go bigger. if you are interested give me a call at 724 464 3169 or can email me at firstname.lastname@example.org. i can send pictures if you would like.
