replaced the 16R resistors and the amplifier came out of protection after a few seconds. This is one of my favorite kicker amplifiers. I ran this model at 1ohm for about a year with out any issues. What is the major difference between the red 1ohm previous model and this yellow decal model.
There where a few things that changed. One resistor value change in the OCSET circuit of Pin 7 IRS20957 chips.
The other is a change to the circuit that controls the current sense Pin 3- of the UC3843, which would require a very detailed description without a schematic, which I can't offer.
I believe the reasoning to go from 1 to 2 ohm stable is, we where seeing a lot of amps come back that where being abused and unrepeatable.
