Yes, unless your amp is stable to run at 1ohm... Thats like what they pointed out, with them wired like that your at 1.34 ohms and most good amps are only rated to run 2ohms or higher. Cheaper amps are rated at 4ohms and will overheat and go into protect very easy when running anything less. So either turn the **** down, or buy a super amp that is 1ohm stable. Or wire them all into serries which will give you 12 ohms and put out very little power but your amp will be saved. 3 is a tricky number which is why its not a common setup...
Look into an aq amp if you wanna keep running it like that then. I've had mine down to .7ohms with no problems at all.
