It just like died with no resolution and reading the story I felt compelled to reply lol.

Can you elaborate? Why wouldn't it work? Another option is to make your own clipping indicator, for which there's plenty of tutorials on the web. You just need some basic electronics knowledge. Then set your gain backed off of clipping on the loudest volume you'll play your system at. From there, watch the indicator and make judgements if you need to tune the gain further. To be clear though, I'm not knocking the DD1. If you have the money, go for it because it will simplify the process and is cheaper than a scope. Steve's videos point out that although a scope shows you everything about the signal, you need to know what distortion actually looks like. The DD1 has a simple light that blinks and tells you to back off. Now, is it too sensitive and can a quality system handle some soft clipping and minor distortion in exchange for more output? That's a judgement call.

Dude you must have a wire SPAGHETTI from what I have read so far. I feel your pain, this system should not be giving so much trouble like you are experiencing. I'm running two Sundown U-12 D2's wired to 0.5 on a Nendo 4k. Two XP2000 batteries paralleled to my stock car battery and stock alternator. Solid voltage above 14 almost all the time unless it's a big bass drop and I have the volume cranked. This is all in a little unibody Ford Fiesta. No real issues with the system. I used a scope to set my gain initially, and I watch the bass knob clipping light. I'm probably babying it because I haven't really smelled glue yet. The wiring though....One run of 1/0 between the back batteries (need to double check this, might have a double run here), double 1/0 from the back batteries to the amp, double 4 gauge from the front stock battery to the back ones. Same ground runs as power runs. Bing bang boom.

Keep in mind that different songs have the bass EQ'd at different levels. Even though you set the gains once, you can still get clipping. Only way to know live is to use a clipping indicator such as on certain bass knobs. My Crescendo amps have them.

Sounds like them speakers B 2 expensive.

I got two of U12 D2's from the Sundown yard sale, they were marked as loose. So far I've checked them free air on a plate amp from an old powered sub just to verify they work. Both work and I didn't hear any rubbing. Haven't played them on my system yet, I had to use a drum sander to widen the holes in my 2x12 box. Super excited to see what these things can do though, will know soon. 4k amp is on the way too, then things will really get interesting!

Uhhh 13.6? That's like fully charged float voltage isn't it?? You wanna charge after you've used a good chunk of the reserve, I'd say when you're seeing low 12's.
