BTW, are you sure that sub is broken in yet?

How many watts is the sub at RMS & at what ohm?

How many watts is the Amp at RMS @ 2 & 4 ohm??

They should match.

Ex - if the sub is 500w @ 4ohm, then the amp should be 500w at 4ohm

Its a d2 wired at 1 ohm. The amp does 500rms @ 1 ohm.

Max RMS is 450 which is conservative. I suspect the amp is not up to the challenge or the application just does not deliver the amount of bass you need. This really is an SQ type set-up.

The amp can do 500rms no problem. Its just not loud because of my expectations lol.

So is there no way to get the volume to show on idrive? I hate guessing when setting my gains.

You gotta count the number of clicks on the volume knob, I think something like 55-60 is MAX and 45-50 is when the signal distorts. Ive never figured a way to get my cic to display the volume, I don't believe it is possible.

Replying to this hoping to find an answer to why my e90s eq button isn’t working.
Someone once showed me a secret menu and I’ve since forgotten and now I’m just getting royally pissed off trying to figure out why my subs aren’t working under the seats.

Do you have the idrive or the pro radio manual ?
What year is your car?
Are you sure you have logic 7?

There is no secret menu for controlling the output of the logic 7 amp .
Also it would be good if you read the sticky at the top of the stereo sub forum home page on Logic 7 adjustments.
