I am an Alpine guy as all that know me know.
Lol.
This is my next head unit.

I would go with one 10" and one 12" with one amp each. You will have full range and sound better than two 10s or two 12s.
Get good speakers up front. That. Back...
All this shooting crap makes me sick.
In the last month I have seen on the news over 40 people killed in shooting. That's nuts and I pray for the families that have lost someone in all of this.
I am sure we will start seeing high flowing DPF just like we saw high flow Cats come out. Hell was not ATS (spits) working on aftermarket DPF? Not much came of it. But is a start. We may see twin DPF.
Thinking out loud but maybe use something other than the engine to make the heat need to...
It's been done but was a lot work to make it right. There is a thread on here somewhere about it.

It is a cash grab in Ontario it sucks and is stupid. If I lived 3 hours north I would not need it but I don't so I gave to have one. All 07 and newer diesels have to pass a sniffer. The older ones just get checked for smoke at idle.
Don't come to Canada as it is not good here too. Only parts have no emissions testing but they are trying to get more as it is a good cash grab.
It sucks.
I love my sleeves and SCL I went with Super Diesel for both. I DD with the truck not one problem. I also have a MA TC brace too. Can't go wrong with them.
