Question about Boss Riot 2500D Car Audio Amplifier
I recently bought a boss 2500d. It performs well during the first half an hour then it trips off, and after five minutes it would come back on or I could I take off the power and put it back on, then it would play for a min and trip off back. During this time the protection light comes on then switches off accordingly. The speaker is new and not faulty and within the stipulated ohms specs the amp is designed for. All connections and wires are new and insulated and well connected including power and ground. Sufficient power is supplied to feed the amp. The amp gets extremely hot when playing at 2, 4 or even 8 ohms at only quarter the gain level and half the head unit, then it trips off. Does it nead a fan or something? What's up with that? It seems as though when the amp is cool it plays continuously. Could it be failing output transistors or a lack of proper contact thereof?
The amp is monoblock so there is no bridging of a single channel to itself.

If you are bridging the amp then you must DOUBLE the "ohms load" that is specified. I.E. If you need 4ohms per channel, then when bridged you would need 8ohms per bridged channel. If your load is indeed correct then you have a fried output probably. Try to run it without any speakers on it. If it still gets hot then you for sure have a fried amp. All the symptoms you decribe sound just like you have too much of an "ohms load" though.
