I'm preparing for an install coming up during Christmas break which will include Polk SR6500's up front (no rear fill speakers) and 1 10" SR104 subwoofer. The SR6500's will be powered by an Alpine PDX 2.150 and the SR104 will be powered by an Alpine PDX 1.600.
Now, I will be running the Alpine H701 processor for EQ/time alignment purposes but will be using the SR6500's passive crossovers as well. Again, SR6500's will have their own passive crossover while the SR104 will be controlled by the crossover in the Alpine H701.
Can anyone help me out with some good starting crossover points for the SR6500's and the SR104? I know the Polk passive crossovers will split the frequencies up between the midbass/tweeter but won't I still have to apply some kind of high or low-pass setting so that they won't play any incredibly low or incredibly high frequencies? And for the SR104, should I keep the low-pass set to 60Hz or so with a steep slope?
I guess in all of car audio this is the part I know the least about, and it's probably what I need to know the most about.
Thanks for any help!
