[QUOTE="Rochambeau, post: 2351969, member: 570071"] OK, I am gonna need some help on this. Because of the design of the amps, I am unsure if they follow the same basic formula as outlined here. The amps are Alpine PDX and what confuses me is that they are rated at the same power regardless of the impedance of the speakers. Therefore, should I use the same formulas? Using the forumulas as stated here is what I got (wattage gleaned from birthsheets): PDX 4.150 bridged into 3ohm Boston Z6's: sqrt(3*318)=30.88v PDX 2.150 into 4ohm Boston SL-80's: sqrt(4*171)=26.15v PDX 1.1000 into 2 Boston GL512-44's (dual 4ohm voice coils, each sub wired for 8ohms): sqrt(4*1124)=67.05v Does all this hold up? Thanks. [/QUOTE]
