Speakers start popping (clipping?) Help..

  • I have Alpine SPS-600 front door speakers powered by a MRP-Alpine F300 Amp and at really loud volumes my speakers Pop (clip?) Really bad...how do i fix it?
  • Is this amp only powering the front speakers? or speakers all around?

    your amp puts out 50wRMS x 4 @ 4ohms, or 75w X 4 @ 2ohms.

    bridged mode your amp puts out 150w x 2 @ 4 ohms

    If your speakers pop, 3 things can be happening, 2 are more common, one is really rare.

    1: Speakers have ripped/torn surrounds, and the poping is the cone over-excurding (if that is a word). My friend had some blown escort speakers like this, and they made a poping sound when the bass drum hit. 

    2: The speakers are being powered at 4 ohms x 4, which is 50rms per channel. type S speakers are rated to 80rms, so 50wRMS is only 62.5% of 80. It is recommended that you run at least 75% of its rated RMS. Since your not to that, at high volume, they could be clipping.

    3: this is the most whacked out thing that could happen. I don't even think its possible, but if your powering 150wRMS to each speaker, at high volume, the speaker is getting way past its limits, and something (possibly the cone) is distorting, or hitting something (maybe the grille or basket if its even physically possible). This is just a wild guess, but things can happen that are crazy.

    most likely, your clipping. The only way to fix this, would be a more powerful amp, or lower powered speakers. If your only using the amp as a 2 channel. I'd go and get a 2 channel amp that can power the speakers. or some 2 ohm versions of the speakers if they make them.

  • Clipping is caused by having the gain set too high on the amp.  If in fact it is clipping, you can fix it by reducing the gain (higher voltage numbers if it is measured that way).  Unfortunately, this will reduce the volume of the speakers, but it's all you can do (short of replacing the amp as X21 suggested).

    HTH!

    Not at all - your post got me thinking about it to come up with a response - hopefully it helps the OP.
