Hi,

What does it mean if your subs thump rythmically with the bass then suddenly they skip a beat? It almost seems as if they flatline for a second then resume. The music is still there except there's no bass response.

Thanks.

If it's not in the music source, the first thing I would look for is an intermittent bad connection within the subwoofer enclosure.

Or your amplifier is temporarily going into protection mode...

Yep, my guess would be amplifier going into protect, probably due to too low an impedence load or too high a gain setting, or low system voltage.

Stevdart,

Thanks for the responses. Right now I'm using a cheapo 20bucks line-output converter. Could that be the cause of this? I don't think it's a bad connection, the speaker wires are clipped on pretty tight.

Kfr,

I'll have to check the protection mode whenever it does that again.

DYohn,

The gain is left at the amp's factory setting, the lowest. Regarding the voltage, the voltmeter on my radar detector jumps around like crazy but never dips below 12v. I wonder how accurate that is.

BTW, Rockford Fosgate T20001BD powering 2 T112D4 subs. Would stock alternator, battery, and no capacitor be able to handle it? The strange thing is when I first started playing none of this happened. Now it does it for 15-20 mins then it's normal again. I've only had the amp/subs for 2 weeks though.

I can assure you that there is no "factory setting" for the gain on the amplifier. It is designed to be set based on the input signal voltage coming in and is different for every install.

As for the voltage, he is actually talking about at the amplifier itself. You might be reading good votage off the battery, but if you have too small power wires or poor connections this could reduce the voltage the amplifier sees and create the problem you are having. I would first suggest checking your ground to be sure it is a solid connection to shiny bare metal.

Turns out it was a loose remote-on wire. How dumb is that LOL. Thanks for the help everyone.
