[QUOTE="hispls, post: 8025212, member: 614752"] Halving impedance is 4X harder on the semiconductors in your amp. As has been mentioned with high current you get high heat which = inefficiency. When folks brag about their 80% efficient amp that's most likely at one frequency, full blast, and at 4 ohms. That all being said, depending on the sub and box you may well not be anywhere near half ohm when you burp anyway. In fact if it's your burp frequency I'd think it's almost impossible for the impedance to be at nominal impedance... if it is, you're doing something wrong. If we hook up before you try it we can do an impedance sweep on the sub in-box and you can see precisely what the amp will see at any given frequency. For now, if you want to be safe only wire down to .5 to burp [/QUOTE]
