long story short...
I had my local shop test my Clarion dxz855mp over the weekend, and they said it got hot after awhile.
Since that head unit has an AMP cancellation option (and I will be using external amp for door speakers and subwoofer), I am wondering if this may solve the problem.
I have just spent so much money recently, that I would like to use my old clarion unit since it was (and still is) a very nice unit.
Does the internal amp create all the heat?
