Memphis Sub Started Popping tonight?

[Ramrod 10+ year member]

Here is what I have...

Memphis 15-PR10D4v2 10in Sub

in a Atrend ported Box (1.25 cubic Feet)

Rockford Fosgate R500-1

It's all in a 2010 Dodge Charger if that matters

I've had this in for months now with Zero Issues. All of a sudden tonight on just one Song.. At just a few certain spots where the Bass hits. It POPs BAD...Never done this before tonight. Played that same song tons of time from the Same source. I didn't have time to do anymore then just get out and see it POP and shut it off. Had to head into work. I don't know much about this stuff.. Just some of the very basic stuff. What should I be looking at or checking first?

It took me a few days of adjusting the amp to get it from shutting off after 2min of playing. But after I adjusted my AMP better. It's been fine. It's been months since I've touched it. Other then my lights dimming when the bass hits at times. It's been very reliable. All I want it a reliable set up.

The Box isn't finished, just need to do some little details to look cleaner...But I'm not a master at this...First timer

Box not tuned for the frequency the subs trying to play. Too much power Subs bottoming out

Can this change over a certain time period? Say like 2-3 months....

I've played that same song over and over in the past with nothing changed.. For months. I'll get a picture of the Settings on the Amp in the morning and post them. But everything is already tuned to 1/4.. I believe....

Just found the spec's on the Tuning Frequency of the Box 42Hz..

Do I just turn the Gain Down or adjust the Frequency to match the Box? Little confused here..

Thanks for the help.

It can after the subs suspension breaks in.

It can after the subs suspension breaks in.

Thanks, I thought that might be possible.. I turned down my Gain, but I'm not sure which direction the Freq. needs to go. Here is a picture of where its set at now. Sorry if the picture is HUGE, but I didn't want to shrink it. Incase it couldn't be read..

Gain needs to be set with a multi meter low pass at 80 hertz. Phase on 0 no bass boost

Gain needs to be set with a multi meter low pass at 80 hertz. Phase on 0 no bass boost

Is this a good way to use the multimeter?

How to Adjust Amplifier Gains Using a Digital Multi-Meter - Knowledge Base

I went ahead and put the low pass at 80Hz and the Phase on 0. Doesn't hit near as hard as it did...I have only had two systems one in a hardtop Wrangler. One 12in in a Custom box and the other was in a small hatchback. two 12's in a bandpass...Maybe I'm expecting to much from one 10in Sub in a Trunk.
