    Good deal man. We were in the area this weekend, wish we could have made it out to Belton to ride with you guys.

    Harpoon cut off yesterday and when I touched it I think I almost burnt my hand. Charged all the batteries over night and went out again today and it cut off again. Fml

    With no more than two pair of surf speakers on a Harpoon something else has to be going on here.
    If you are trying to drive surf speakers extra hard at wake range then I wouldn't be surprised.
    Make sure that the DCR of all four tower speakers are nearly identical. Since you have 'Q's remove just one at a time to see if the amplifier doesn't start running much cooler. This would indicate partial damage in that speaker which can create an inordinate load.

    Can't you just check resistance across the speaker to see if it is damaged? I never run more than 75% volume. I have butt connector in my speaker wire half way up the tower, could those be adding resistance causing the problem? Should I run 12 or 14 gauge wire here instead of 16?

    Also the ambient air temp was about 100-104 degrees. The
    Volume according to my ws420 was between the half marker and the next marker up. we turn it about right there when we pull someone and then cut it off when the fall. The cabins and sub were doing this before the battery changes but we never really took them past half volume this weekend and we never had a problem

    Yes, you can check the DCR for consistency (+ or - .1 ohm is fine) between speakers but if there is an issue with a tweeter then it will not show up since it has a series capacitor in the highpass section of the passive crossover network that will not pass DC.
    A butt connector absolutely creates resistance which is why we solder and heatshrink everything. In fact if you have a butt connector on a 15 amp halogen light supply harness it will get hot enough to burn you.
    For the kind of power you are running 14/4 is par for four surf speakers and 12/4 is the norm for four HLCDs. 16/4 is light although its doubtful that either of these issues are the actual cause for your thermal failure.
    The relationship between a volume control and output power is not a linear equation. If a volume attenuator works in 1.5 dB increments then cutting back two clicks is half power. Cutting back six clicks would be one/tenth power. So I'm not sure what you mean by,"75 percent".
    You could email me. Maybe we'll set up a phone conversation. We'll start from the beginning. I need to verify a number of conditions. david@earmarkcaraudio.com

    75% just means the knob was turned 75% of it's total travel.

    Default Amps Over Heating

    THREAD REVIVAL!!!!!

    Sooo what was the solution!?

    I'm having the same problem. I'm running 2 Kicker 700.5s (1) to the Exile cabins and sub (1) to the Exile towers

    It's 100 degrees out. Amps are both smokin HAWT to touch, go into protection mode, 5min break and back to business.

    I have 2 batteries with perko switch that are possibly needing to be replaced, but don't wanna go that route just yet if you guys figured out it was a separate problem...

    Amps can and will be hot to the touch, but that in itself doesnt mean they are going into protect mode due to their internal temp. You have 2 identical amp, but both may be used differently. Are they both going into protect mode at the same time? If so, I would look into something other then heat, like battery voltage. Is this a problem with the engine running or while at anchor or both? What gauge amp cabling is used for both amps?

    How many speakers is each amp driving? Is the sub a 2 or 4 ohm load at the amp? Are the amps bolted directly to a carpeted wall?
