I upgraded my speakers in all four doors of my 12 Screw with Infinity Reference X Ref-8602cfx 6x8's and while fading from front to rear, I noticed theres no bass coming from the rear speakers, fronts have plenty of bass! Is they're a frequency cutoff in the factory HU, and or wiring? If so, is there any way to Defeat/remove it without installing a aftermarket HU? Thanks

Cut off on high volumes. Are you sure you have the polarity correct on the rear speakers?

I used the Metra speaker adapter harness, to avoid cutting factory wires, they're labeled + & -! Id find it odd that I some how got both fronts right and rears both wrong!

There is bass in the rear, just isn't as much as the fronts...

I noticed the exact same thing, but I noticed it with the oem speakers also, I put Polk Audio DB571's in all 4 doors but the output remains the same so that tells me it's the HU.

Bias to the front much like a proportion brake valve, put the pressure up front where it's needed most.

I see one of two solutions to fix it,(one) adapt as I have or disconnect the rear speakers, wire in an amp and then hook back up to the speakers.

My old ears have had enough of that ground pounding rattle fillings out of teeth thumping.

(Two) Accept the fact your getting better quality sound from the upgraded speakers that are still not pushing as hard as the fronts.

Just letting you know your not alone, from there the options are personal.
