So, with the dd1 I get nothing but a power light and a distortion light when setting my gain, the volume is at 45 where I could here it distort at 47, so I just backed it down a couple. Only did this because I tried to see where my h/u distorts at (DEH-8600BH) but got nothing, no lights or anything, through the amp and with trying it through the RCA's. I didn't want to make a long title, but I'm also having problems with my cc1 where I get a power light and a red signal light (green is good) even with the volume at 0. These both being hooked up to (+) and amp ground. Need some help here, thanks in advance.

For my primary, but thanks man

Would the XP950 be too small for my 2004 Tahoe? I can't find anything for my question anywhere so I thought I'd try on here.
