Common air volume. The other side has a piece of wood that starts the port behind the sub also.

Bass mids and highs are all clean. No distortion. I asked about the piece of wood, to close to the vent hole, they said it's no problem. That's the inner border of the hidden battery box. The top left is the back of the box

They used a voltmeter and checked the ohm on the sub terminals(4.2&4.1) and then checked the speaker wire from the amp to the sub while they had a special cd in the head unit. (90 volts)
That's how they came to the conclusion the amp needs to be turned down.

No sooner had the subwoofer been replaced, it started smelling after a minute of play time. Turned around, shop took it back out. They are gonna turn down the amp next. It's only the left side I have had problems with. Getting ANOTHER one tomorrow.... the amp apparently had been running at 90%. Maki...

So who's the owner now? If it's for sale, I've got some cash to throw at this.

Sorry for the run-on post. I'm here because you guys have more experience than I do, so bear with me. Picture so you can visually see the majority of what I'm working with. 89F0592B-4A66-4DC5-B12C-9B16469A038B.jpg Has anyone owned the new elite 12d4s? The tri-led keeps going out. I'll replace and 2 ...

Knightrider, what on the head unit would make it clip? Subwoofer level? Q factor? Loud stays off. Eq is balanced at zeros across the board.

Have any of y'all experienced a song that just kills your subs?? Like I said I have ran this for the past two months rattling cars beside me the whole time. No problems.
The song that was playing at the time of the smell and blown sub was o pana by $uicideboy$

Ok. I know the elite d4s are rated for 2000 watts rms. They used a tool(dmm?) to calibrate the amp with the head unit volume at 31 out of 35. I also noticed the subwoofer level on the head unit goes from -50 to +10. It was set at +10, then the amp was calibrated. I'm thinking calibrate the amp when ...

Think I just roasted the coils on the pair I have now. Also had to send a couple back because the leds always failed. Other than that they are monsters. I run my pair in a ported box on an elite.1

I'm running 2 elite d4s on an elite.1 amp(3100 watt mono) among focal mids and highs. Daily listening, pissing old people and soccer moms off (I'm in central Florida) I listen to bass heavy music ($uicideboy$, lil wyte, and some edm trap) Ran the system for the past two months no problem. Today I'm ...
