I agree, a second 1206D wouldn't hurt. I have one 1206D pushing a Rockford T1 which they recommend to power with 600 watts rms. I wouldn't worry about overpowering it. Its comparable to the Type-R so I'd say the extra power wouldn't hurt unless you crank the gain and play test tones all day. //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif
