ok, so just to have a public record of our deal, we have agreed to trade his 4kw for my xx-goliath. we will be shipping out tomorrow, wed, march 14 to each other. i am aware the amp he is sending me has a few minor scratches but it in working order. he is aware that my amp also has some minor wear and scratches. he is also aware that it cuts out sometimes at high volume and goes into protect for like 1 second or until i turn the volume down for just a second, then it comes back out. he is also aware that i cant giev him a warranty on it, because he knows the problems i had with the amp when i first got it before it was repaired by CIA. he asked a couple questions about it, like when it goes into protect, does it make any odd noises or smoke, and the answer to both of those is no. i believe, after we talked through what it was doing, the protection is either due to voltage drops or i know that the goliath's are known to have a problem with the 8v preout my HU gives it. thats about it, anything RC wants to add, please feel free.
