Ok, I just installed my new Cadence QXR-7 (three way electronic crossover). I basicly wanted it so I could bypass the JBL 1200.1's crappy ass crossover. I hooked both my amps up to it 1) Cadence Q3000 - Feeding the component set. 2) JBL 1200.1 - Feeding my baby Brahmas. The tweeters are clrackling at high volumes now. I also dont know how to set the gains on the amplifiers. Should I have them all the way up / in the middle / or all the way down? It seems the higher I set the gains on the amp the less crackling there is but I dont want to blow anything up!
