This is merely a common misconception/myth that you'll somehow save both subs if you're feeding both the same amount of power and only one happens to blow. That in and of itself denouces this argument, but the main point is that if you do blow one in a seperate chamber, instead of sending it RMS, you're sending it 2x RMS. It's going to blow no matter what size box it's in; how long it takes to blow is the question to ask.
Agreed. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Thats if you are running a single amp or a set strapped to both drivers. If you are running 2 amps unstrapped to each sub if one blows, the event of the other blowing is Next to nothing. lol.
Thats on 2 seperate chambers. In a Common chamber it's different.
