Review on JBL MA6004 4 Channel Full Range Amplifier by Darryl Pendall

Used to slide a pair of 6.5 inch two way speakers into a boat. We used the booster intermittently at best, maybe once or twice a month. The sound is good, but maybe a bit heavy in the mids. The amp died after just over 2 years of use. When switched on, the lights hardly flicker. Connections checked, battery charged. It just unexpectedly expired in the middle of a day's fishing. Hopefully these new Bluetooth boosters will last a little longer. It works without a cable.
