## Questions & Answers

**Q: What amp would be best for mtx terminator 2 12**
A: I have the pioneer 1000watt that works good with my terminator 12s.

**Q: Will this work for two 8in pioneer shallow mount subs?**
A: Works fine for my two 10 inch Rockford Fosgate subs.

**Q: using an ipod nano as the input to this amp, will it turn on automatically and will it function properly?**
A: Yes you can. But the output voltage from the nano is a maximum about 1.5 volts. So you would have to run a short RCA to 3.5 adapter for signal loss. Also you will need a switch to power amplifier on and off. I have done it. Also you will have no ability to equalize the sound.

**Q: Will this work for (2) 10 inch rocford fosgate subs**
A: That's actually what I'm using it on. I have two 10 inch P1s and it works well. Both my subs are on a single input and if i try to bridge them, it cuts out so i just use a single channel and it sounds good.
