I installed my mtx sub and amp. The amp is 800 watts at two ohms and that is what I am running my sub at. I just blew a 40 amp fuse.. I wonder if I need a bigger one. There isn't any stereo shops open right now so I'll just have to wait to buy one I guess.
It's this amp http://mtxaudio.com/caraudio/product...hunder7801.cfm
and this sub, the 10" dvc. http://mtxaudio.com/caraudio/product...hunder9500.cfm

 

I looked at the link but can't find any information on current draw. You may want to read your manual in detail. But I have 2 amps right now outputting the same power as your 1 amp, a 500 watt and 300 watt and JL Audio says each draws about 40 - 45 amps so you'd probably need a 100 amp fuse.
