-elias- Posted November 27, 2019 Report Share Posted November 27, 2019 Hi guys, new to the forum. i posted earlier about this topic but I think I was in the wrong category. So im trying again, asking for thoughts on this setup. would like some tips for using the “active” crossovers on my alpine-178bt headunit. The idea was to use the highpassfilter (set at 100hz) on the “rear” RCA output on the headunit, going to the amp (for-x500.4) with an y-split into both the front and rear RCA inputs on the amp. Then using the amp’s lowpassfilter (set at ~5000hz ) on two of the amp’s channels witch i will be running 4 Vibe Black Death 8” mids on. The remaining two channels on the amp will be used for 2 tweeters (crossed over at about 3500hz with the amps highpassfilter). I was then planning to do the same on the front RCA output, with exactly the same amp and speakers, except I will be running 6,5” mids instead of 8” and setting the hpf at about 140hz ( instead of 100hz, like on the rear channel. Is this doable? I read somewhere that it’s never a good idea to use multiple crossover points, headunit,amp etc. that it would change the phase of the signal. Can someone explain if, how and why? thanks! Link to comment Share on other sites More sharing options...
