[QUOTE="m4rkw, post: 8659484, member: 675828"] Hi In my car I have a JL Audio CS112g subwoofer box, 600w @ 2ohm, powered by a 1000w xfire amp. At home I have an Exposure 2010s2 hifi amp which does 75w per channel @ 8ohm. I'd like to be able to run the sub indoors but I suspect it would strain the hifi amp to death and kill it. What's the best way to go about this? The hifi amp has a preout, not sure if that's active at the same time as the speaker outputs but if it is then I could run that to the xfire amp to power the sub. Assuming that's doable, is there anything ready-made I can buy to run power to the xfire amp? What about controlling the bass, there's no subwoofer control on the hifi amp so I'd need some way to adjust it, I suppose I could just use the gain on the xfire amp but I'd prefer to leave that set so it's correct when it goes back in the car. Any tips on doing this appreciated. Cheers, Mark [/QUOTE]
