Used wisely, you new Merlin will provide a lifetime of fun and enjoyment. Since
hearing damage from loud sound is often undetectable until it is too late, U.S.Amps
and the Electronic Industry Association’s Consumer Electronics Group recommend
you avoid prolonged exposure to excessive loud sound.
We want you listening for a lifetime!
Jump starting your vehicle can cause large voltage spikes within your
automobile’s electrical system. To prevent damage to your stereo system, make
sure the entire system is shut down until full battery charge has been reached
and jumper cables have been removed from the battery.
