I'm planning on adding an amp and actually have been looking around.My problem is several amps i see like the odyssey ht3 dont have 12v trigger.If they dont have the trigger how are they used,do you just leave the amp on all the time?Hate to have to always turn on the amp seperately.Any help or insight would be appreciated.thanks
P.S. by the way i'm actually looking to see if any used low profile amps are available or even exist.
