Rockford Fosgate designed the PP8-X crossover to work with a Punch Pro Series midrange speaker and tweeter. The PP8-X provides low-pass filtering for an 8-ohm Punch Pro woofer (3,000 Hz at a 6dB per octave slope), while Punch Pro Series tweeters include their own built-in high-pass crossover (4.5K Hz, 6 dB/octave). Don't worry about that "gap" in the frequency coverage, as the gentle 6db/octave slope ensures that the final response is perfectly blended and smooth.
It's easy to set up your system. First, you select which tweeter you're using (the 2- or 4-ohm model), and then choose from three tweeter levels (0, -3, or -6 dB) to suit your vehicle. The PP8-X features two woofer outputs, in case you want to double up on your Punch Pro midrange drivers for some real fun. The PP8-X handles up to 125 watts RMS, which is what Rockford Fosgate recommends for maximum performance from the Punch Pro speakers.
