Hello, I am attempting to use the Droking TDA7297B mini amplifier as a mp3 player amp in a project I am working on.  I purchased the 12v 2a adapter as a package via Amazon.  I am trying to use the adapter to also light several 12 mini lamps in project.  When I wire it up, the amp blue light will flash about 5 times and powers amp and lights.  The mp3 output via the 1/8 mini plug sounds great via amp.  What causes the flashes before starting?  Perhaps a 12 v adapter rated at higher amps will solve it or can I use the adapter I have and wait for the delayed start without any dire consequences.  thanks for any advice!
