you must got really incompetent shops. Clipping at 8 ohms is still clipping at 8 ohms, With noobs nowadays they'll be soo dissatisfied with the output that they'll blow the sub even at 8 ohms, they'll likely put on some bass boost or bass EQ rather than doing proper level adjustments. With impedance rise you are actually seeing around 16 ohms reactive wired to 8 ohm nominal. Dont assume that everyone will be as stupid as the shop doing your setup lmaoooo.That sort of thinking is why an audio shop blew one of my subs years ago.
I was having them install a new battery, but they decided to start fiddling with my amp gain. I had it turned down to avoid over driving the sub, but they turned it up just below clipping, then blew the sub while testing. Thankfully they gave me a replacement and owned up to their mistake, but it's stuff like that that has me play it safe when giving advice.
It would be safer not to hook up the amp at all lmaoso how much power will that sub pull from the amp wired to 8 ohms? 25 50 100 150 200? and how much if wired to 2 ohms? Can he get another p3 and wire to 16ohms? Would that be more safe?
I'd comment but I don't want to get my hands dirtyIt would be safer not to hook up the amp at all lmao
