let me welcome a thought i have. 2 amps independent vs strapping. Assuming they put out the same power either way.... Strapping has as interesting feature that many people don't think about. Current. The more current that is requested, the larger the wire needs to be... The more current that a speaker accepts, the closer the thermal threshold is... At some point, it could melt the tinsel leads, coils, etc.. Look at what happens when comparing independent vs strapping- Let's say we have 2 1000w amps. 1000w@1ohm or 2000w strapped at 2ohm. Right off the bat.. Why is the minimum load when strapped change to 2ohm? Because most amps, when strapped, are done in SERIES. What happens when you series batteries? The ONLY thing that happens is a doubling of voltage.. All current characteristics stay the same. So how does this translate to amps? Let me show you- each 1000w independently does 33v, 33a = 999w. So if you had 1 sub, 2 amps, one on each coil, it would accept 66A to achieve 2000w! YIKES! That's not safe! What if we strapped them? Strapping would double voltage, but maintain same current output(theoretically, current will go up slightly, but not much!) IE- 2000w @2ohm = 66v, 33A.. What?!!?!?!? Yes, the same current in, but double the power! This is my take on strapping is better, ONLY AND I MEAN ONLY if it helps reduce innefficiency from thermal threshold and longevity playback(anything but burps)
