Think the driver in my jensen spx -17 sub woofer has decided

Customer Question

Hi guys think the driver in my jensen spx -17 sub woofer has decided to retire . Works fine on initial start up but after a short period in operation starts to emit a series of fairly loud intermittent popping sounds . Done the standard check the cables , connections plugged it into a different power board etc . It is 12 yrs old . Can you confirm my suspicions its time to get a new unit thanks for any info provided. .. Shane

Hello and sorry you're having problems. Offhand the intermittent popping sounds point directly to the amplifier IC chips failing. More specifically, failing under normal operating voltages/temperatures after initial startup. To fix this would require at least having the IC's replaced (on average a $150 repair), replacing the plate amplifier which is more cost effective, or replacing the powered subwoofer itself- which you can replace for almost the same cost as repairing it- especially since the unit is 12 years old.
