HAHAHA hucklburry...
I have run an amp off my Samsung for years. No radio, no dash hole, just an amp that also has bluetooth so I can be legal when driving and answer my phone hands free.
I have to coast or be doing about 35 mph or so since I have an open wind screen on my 1/2 cab and lots of horses but it's very doable if I'm coasting or cruising thru town.
