[QUOTE="lil azn 06, post: 1878305, member: 563170"] With my passive crossovers always cutting off at volumes it shouldnt, i believe i have no choice but to go active. Ive read up on an thread here about active vs passive and it says something that is needed.... lots of time to tune. Unfortunately, i work 10-15 hours a day and really dont have energy to do all this. Basically i need help setting it up towards where i wont blow my speakers when i first start using them. Here are my specs JL 300/4 2 way Rainbow Pro fi Kickbass Alpine 9855 The amp [IMG]http://img.photobucket.com/albums/v226/lilhplaya06/untitled.jpg[/IMG] Speakers specs (off manual) Frequency response 80-25.000 Hz Slope 2 x 18 db octave Crossover Freq 2.400 Hz The 9855 has a built in crossover as well that i really never messed with because i never really understood how it works. My questions are - When going passive, is it okay to use a y connector to split a 2 channel connection from the HU to 4 channels to the amp or should i do 2 runs of RCA connectors from the HU (one set of rcas as "front" and one as "rear" from HU) to the amp? - How do i set this up towards where speakers dont blow when i first start using them? - what settings should i set on the amp (look at pic above). Im going to already assume all of it is going to be bypassed to High or at least the tweeters will be. - What crossover settings should i set on the HU? All i want is a safe side to do things for now and still sound very good, after understanding this all more and having more time ill tune it to how i want it to sound. Thanks [/QUOTE]
