You should build a new box. Woofer and port on same baffle. I never could get loud with sub up port back/port side. Always was louder when woofer and port is on the same baffle.
The enclosure is the most important part.
RE is old news. Get a pair of sundown SA 12s on a 2k amp and you will be happy. Don’t get a prefab box. Get a nice box made that’s like at least 2.5cubes per woofer. JL still makes nice stuff
Put them 12s in a huge box and they will shine. I have my 2 SA 10s in like 11cubes and it’s awesome! I know this video isn’t sundown but watch this video of 1 12” in a HUGE box. Space makes bass.

Kinda hard to tell but what’s up with the port on the new box? Looks like it doesn’t fit all the way? Anyways u want the port to aim throw the hole in the rear deck and not the woofer. 😎
Sounds like your loosing signal and not clipping? Not sure. Sounds like your a very beginner and it’s hard to help over the internet on this kind of problem.
Clipping is distortion and hardly can be heard with subwoofers. Voltage being 12.4 doesn’t mean it won’t clip. My guess is u have a...
Lmao measure any woofer. They all measure smaller then they are. Skar just *****. Sorry for your purchase. Also a 10” woofer sounds just like a 15” woofer. Idk what your trying to say in your first post
I had a Memphis 1000d on my two LCS 12s. Amp has 4 30a fuses and put out some good power. U could Prly run a 1500watt amp to them and after rise and just clean power they would be safe.
