Recently my 1200D has been going into protect after about 30 seconds of being on and I have no idea what's causing it. I always let me car run for a few minutes before turning my amps on (they are both on switches). Two days ago I went and bought all new brass screws, bolts, and washers and re-did my grounds for both the Sundown and my Pheonix Gold amp. I sanded the paint off the area and tightened them down. Yesterday I pulled the Sundown out of my car and opened it up to make sure nothing burned up. Visually, everything looks perfect and my fuses are intact. I guess the problem started when I got my component set but I don't see how that could be the issue. I've checked the voltage at the amp and battery and both are right around 14.5v. I'm hoping somebody can point me in the right direction. I'd hate to have this expensive amp just die on me like that.

edit - Forgot to mention my gain is only a tad more than 1/4 of the way up. Not sure if that helps at all, just trying to give as much info as possible.

New or old model?

Old model.

What's the impedance of the sub woofers

They only come as D4s and are wired down to 1ohm. I checked the impedance earlier on my voltmeter and it read at 1.1 ohms. I didn't pull out both subs to check them individually but I assume they are reading fine since together they are wired as 1ohm.

I just pulled the subs out and each coil is reading right around 4ohms. I really hope this amp isn't done.

I can check out the amp for you if you cannot resolve it.
