## Questions & Answers

**Q: I have this paired with one type r 12, where should i have the gain set so that i get the most out of my sub without blowing it?**
A: I would set it no higher then half with the bass boost about third way up. I blew a 15" type r with the same amp wired art two ohms

**Q: so it puts out more power at 2 ohms more then it does at 1 ohm?... im confused**
A: Yeah, Alpine built this amp to be a 2 ohm amp. That's where this one puts out 1000

**Q: Can this amp handle a 10 inch 800 watt skar sub?**
A: Is the subwoofer 800 watts rms or is it's Peake power 800 watts? Either way if it's true is 800 watts rms then yes the amp can more than handle the sub. But the thing is...... alpine products are 100 percent spot on when it comes to there information about true power.... other lower grade brands fluctuate dramatically. My question to you would be can you sub actually handle  a alpine amp at a true 1000 watts Mrs.? I have 2 of these amps powering 2 12 inch 1000 watt type r 1000 watt rms alpine subs and they put out a ton of power.... I ended up also upgrading to a competition alternator.....

**Q: Would this amp be a good match for my (2) 10" Audiobahn aw1000x/4ohm/dual v.c./600watts rms (each)? Any response would be greatly appreciated.**
A: You can only wire those to 1ohm or 4ohm with both subs, so you'll only get ~600Watt instead of the 1000watt at 2ohm.  It should work fine, but just not as much watt/$ as if you had a 1ohm stable amp or 2ohm load.
