Hey all, I just replaced my rear pod speakers with Polks and had wired in bass blockers from PAC (even though Ford’s software isn’t currently allowing full range to the rear anyway). They sounded like an AM radio and then I realized the PACs are cut off at 1200 hz for 4 ohm speakers (they are advertised as being specific to 4” speakers). So into the trash those bass blockers went. Rear sounds better now (though still not great). Now I’m wondering if I should even use bass blockers in the front. I know most people are blocking at 300 hz, and I will definitely be returning the 1200 hz blockers I have. So no dash install today. Unless…I don’t really need them in the front at all. I’m keeping the factory 6.5 (for now), which I assume have a built-in crossover. Which, if true, would make the bass blockers up front unnecessary, no? If not possibly detrimental?
