Anyone know the rms the amp puts to the rear 6x9s?

Hey SW, did you ever get the system completed?? I was following closely on DIYMA

I kind of did...then I actually decided to redo things.
I never was able to get a replacement minidsp (they ghosted me) so I ended up replacing my amp with a Helix P-SIX and my subs with a JL Stealthbox 12W6V3, which I'm still waiting for, and a Helix P-ONE as a sub amp. Once I have these installed I'll update my build thread.
I'm still using the NavTV unit and it's been fine so far.

If you know their impedance (2Ohm or 4Ohm) you can put a multimeter on the speaker terminals and calculate it. The only issue is you'll have to run a 50Hz sine wave at almost max volume and I think the factory Bose amp attenuates the bass at high volume...plus, it's not fun listening to a 50Hz sine wave lol.

Yes the factory system has active bass attenuation to the rear package shelf speakers to prevent overdriving and clipping at all volume levels and bass levels.

That's why in order to get a proper sounding system in this car that does not roll the bass off at higher volumes you need to completely gut everything and start from scratch, replacing the factory Bose amp with a Zen AVB processor, all new aftermarket amps to run all the speakers front and rear, and completely new speakers all the way around.
