We put this amp in a Jeep Wrangler that frequently has the top off and is in sand and dirty areas. The amp stays nice and cool mounted under the back seat and work great in conjunction with a small kicker sub that replaced the factory sub in the factory arm rest enclosure. Our Jeep thumps well with this amp and a single 6" kicker sub. Plans to add a second sub next to the amp in the back to get even more. VERY pleased!!
