S*** , System help!!

My friend just got infiniti's with tweeters, he wired them to a rockford 2 channel amp through crossovers. With some sony ( dumb ) deck that was like 200$. Anyway, they work great, but he also purchased 1 audiobahn awt12( i'm not sure of the model, but its ~600rms.) With an audiobahn 800t amp. Which i think is 2 ohm stable, he says. Anyway, in order to get the pwr, gnd, remote to both amps, he used T's to split them. He was bumpin for a day, and the next he was crying. :grinno: He said WTF, and i checked the T's, and the one that carry's the pwr current was F'd. It splits(obviously), but the one going to the spkr. amp is fine, but the one going off to the sub amp was blown. I checked the ground, it was to a bolt in the trunk, pretty good. He wired the sub, which is dual 4-ohm parallel to get a 2 ohm load. Anyway, why did it blow the fuse? And why not the one on the main pwr lead from the batt itself?

K, now let's forget all my questions/stuff i said their, and i'm wondering why would/could this happen in the first place? The amp would go into PROTECTION right when the car was turned on. That's obviously not good. He said it never got hot. Just went off. I thought, shit, is it wired to a to low of an ohm. But its not....2 ohm, which is stable for that amp. So i have no clue. could it be a setting on the amp itself? Why didnt it blow the fuses on the amp? Only the one in the T? I'm totally 110% clueless! Help me asaP! tHaNkS

what size is the fuse in the distro block? (the 't')

thanks! it was way to small. All fixed.
