Review: Best amplifier for JBL subwoofer 1500W - Best amplifier for JBL 1500w subwoofer the quality is good and the performance is great to drive the high wattage JBL subwoofer in bridge mode without any distortion is great quality of this amplifier....... I powered this amplifier with 12 v 15 A SMPS powersupply of tridev.......excellent performance and sound because of high thumbing bass output it is having a minor negotiable heating issue.....it uses max 10A of current and 12 v powersupply for home usage....working perfectly. Update: You have to power this beast with a 12 v 30 A powersupply for clear bass handling which I have purchased from Tridev through desertcart. The 15A powersupply which I bought earlier was not enough 😂😂😂 The heating issue I said earlier were disappeared because of updating the power supply to 30A.... excellent deep bass this time
