lol, no that has nothing to do with it at all.
It has to do with how the output stages of the amps are designed. Amps have to be specifically designed to beable to strap together.
And I dont believe any Home Audio amp out there has been designed for this. There is no need as it is something only done in car audio where extreme power is needed for competition.
Also, when done in a car audio application, reliability is decreased and distortion can be increased. And with todays amps exceeding the 15k mark. Its not really something that needs to be done unless you are competing in SPL.
