Got a kenwood KAC729S amp.. recently found out it's a 2 channel, not a 4 *long story*, but it bridges and it hits hard. Powered two tens and never had the amp at full power.. usually running at about 60% power. Should handle 2 15s fine. Also have a Rockford Fosgate half cap if you need some extra power. Hit me up on PMs and we'll talk cash... looking to get around $100 for both.
