I have a boss audio 2 channel amp that’s 450w rms at 4 ohm bridged and a single alpine type s 12” dual voice coil 4ohm sub in a 1.6 cubic foot slot potted box. I can wire the sub at 2 ohm witch overloads the amp or at 8 ohm witch is where I have it now. It runs good now but lacks the thunder lol. My question is, is there anyway to know how much power I’m putting to the sub with it wired at 8 ohm? Any recommendations on a good amp for this sub? I’m considering getting another type s 12 and going back to a sealed box. Would the amp I currently have be enough power to run two of these subs? It’s 600 watt rms by two channel at 2 ohms. Thanks for any answers
