I had a t1 1000.1 running at 2 ohm and this last summer it died...kinda.... The bass just stopped, then a bunch of f'in smoke came out. So i then quickly pulled over and disconnected it. In its defense tho, i did beat the shit outta it forcing it to its limit and more likely than not clip a lot. It still works but to get the same response the gains must be up higher than before. This was in the middle of the summer....
Funny tho i did go on a trip 4 hours there and 4 hours back and didnt have a single problem compared to the maybe 10 min drive of which it then messed up. Overall it would be an ok budget line IF it was a LOT cheaper than what they sell for. If you decide to buy then buy used cause IMO its not worth over 200 new at all.
