Question on dash speaker impedance & bass blockers.

I got in line for a 2022 Pro back in August. It will be a manual trans so no JBL stereo. I am planning a Kicker retrofit.

Stock head unit.
Kicker KEY200.4 AMP
Kicker 47KSC3504 3-1/2” Dash Speakers (will require some cutting)
Kicker either

$190 47KSC69304 KSC6930 6x9 150 Watt 3-Way Car Audio Speakers KSC693

47KSC69304 or 47KSC6904 6” x 9” Front Doors
Kicker 47KSC6704 6-3/4” Rear Doors

$230 Kicker 11HS8 8” 150 Watt Hideaway Compact Car Audio Powered Subwoofer Sub HS8

Kicker 11HS8 8” Powered Sub

My question is that it looks like the stock dash and front door speakers are 4 ohm, but appear to be wired parallel. If I am reading this right, I think that 4 ohm rated bass blockers installed in the line for the dash speakers will cut off at double their stated cutoff value since they will be at 2 ohms due to the parallel wiring.


Do I have that right?
