It's just plugged into the harness. However Crutchfield had me do it.
Why do you still have that HU then? Which model do you have?
Yep it's a pop and drop for the HU. As for the focal comps, they're like the HAT Imagine IIRC in that they have a built in stiffening capacitor mounted to the woofer. To go active with the focals, just connect the tweeter directly to your highs channel. If you're paranoid about not having the right kind of tweeter protection, PE has stiffening capacitors you can buy separately and just place in line between the tweeter and the amp.
My tweeters and woofer are all on their own channels already. Idk what the hpf is for the tweeters, but the amp only goes up to like 500hz or something, so the filtering must be happening just fine on the tweeters and whatever crossover is built into them because they sound fine.
Its not bad, i can barely hear it, but my highs have a hiss when paused. Its a premier
Sounds like it's the stiffening capacitor, attached to the woofer. Basically has a preset frequency and slope (my guess is 2.2k@24db/oct)
Oh. Mine is pretty prevalent. Especially when I play something like a violin solo or something where there is only one main frequency at a time. Even during the violin solo my sub is making an audible hiss (low frequency hiss) so I'm guessing it's on all channels, which would mean it's the HU's fault, since I have two different amps for the comp set and sub, and also two different brands of RCAs for each amp.
Disregard... The capacitor's role on the woofer or tweeter is to limit the amount of frequencies the speaker will see. It is a passive crossover of sorts. It is usually good for 3dB/octave or 6db/octave depending on the design (1 or 2 caps).
