Step 3Other Required Items - Amp

Sonic Impact Portable T-Amp Digital Audio Amplifier. This is a battery powered 15 watts per channel stereo amplifier. It costs about $30 new. It runs on 8 AA batteries. I'm using POWEREX 2300 mAh NiMH rechargeables from Thomas-Distributing. They cost a bit more but you only have to buy them once and they last forever. I've run the amp at full blast for 3-4 hours without running dry.

Hmmm, it looks like that amp has been discontinued. I got mine from Thinkgeek.com. They only have the 2nd generation $69 amp now. It doesn't look as good as the first one either. Maybe ebay?
