Dc audio never ceases to amaze me (sarcasm alert)

and 20 Hz is low what is your box tuned to?

running sealed. Sub prefers it over ported

I didnt know you could wire 3 D4's subs to 4 Ohms.  Everywhere I've looked online show either 2.67 Ohms or 6 Ohms

where did it say 3?

It didn't I failed at reading.

If you're playing a song on tuning it's not going to cool..the coils don't move enough to cool anything

 

@ tuning 

 

DD-1 works fine, if you use it right. Not setting your gains with -15....

It doesn't work for setting gains, fucking stupid device.

smh at people blowing shit up & blaming the equipment

[Sencheezy 689]

lol umm. Have you checked your wiring yet? lol.

Must have used an excessive amount of db dust

Its funny how this site is gradually turning into the SSA forum peace out guys

Precision Power PPI BK1800.1D

RMS Power Rating:

• 4 ohms: 700 watts x 1 chan.
• 2 ohms: 1100 watts x 1 chan.
• 1 ohms: 1800 watts x 1 chan.

So you are giving them 500W combined? How did you get to the conclusion, what math did you use?

How big is the box? is it the 4.2cu ft in your sig? (that's a little too much, but even that should make any problems with 500W)

Did you double check your wiring? (did you measure it with a DMM to see if it actually is around 4 ohm?)

It shouldn't be a gain problem, I don't understand why so many people think that is the problem. (if you set it correctly with the DD1 you should never have problems unless the amp will put out more power then it's rating.)

The subwoofers should be able to handle 900W RMS, 1.8kW combined, in a sealed enclosure they should be able to handle 1kW, let alone 500W.

I'm pretty sure you are hearing the sub bottoming out, not the dustcap if it's louder than  the bass. (can you fit something between the dustcap and the cone? check this properly)

he's hooked up at 1 or 4, maybe he thinks if hes hooked up at 4 ohm and turns the gain all the way up hes getting 500 x2 =/
