    Clipping vs. Amp safety shutdown mode? Tower cutting out...

    I feel like this is kinda becoming the only thing talked about in this section of the forum, and I apologize for starting another conversation on it, but I didn’t want to swoop someone else’s thread and risk them not getting their question answered. That being said I think I have read most of the conversations on this topic as well as the links, but I’m clearly not smart enough to handle the math of ohms and resistance. So here is my problem…

    Similar to others, my tower speakers cut out at high volumes. I’m not sure if it is due to clipping or my amp. I don’t believe it is clipping because my understanding of clipping is that the speakers just don’t put out the peaks of the audio waves, and when I turn up my volume the speakers just shut down for a few seconds (3-5ish) and will come back on- either after a delay or once I lower the volume. Is that what clipping sounds like? And sometimes it is only the right and sometimes it is only the left.

    Here’s what I am running… I have the defcon IV tower set up (4 tower speakers- all polk momo 6.5’s- wired as 2 on one channel, 2 on the other). I don’t know if they are wired in series or parallel, boat is at lake… have to check next trip out there I guess. All four are being run off one amp the bigger of the two clarions (the 460 (I think- the stock one- just not the 280.)) Its wired bridged, so basically the 2 left tower speakers are from bridged channels one and two, and the right 2 tower speakers are running of bridged channels 3 and 4.

    I feel like that amp should have plenty of power to push those 4 speakers (even at high volume) that is why I am suspecting amp safety shutdown mode (if that even exists).

    Not sure if it is a power problem or a wiring problem, or both, please help, thanks everyone.

    nautiques4life,

    Sounds involved. Not sure you share the same issues as '09s. We'll set up a phone conversation.

      Sounds like the amp is overheating.. How are your speakers wired; ie 2ch +4ch amp
