[QUOTE="Doxquzme, post: 8865021, member: 689267"] Okay, so with this amplifier, you can eliminate the inline x-over (recommended) as the amplifier is better at doing this prior to the signal going to the tweeter. To keep things straight in your head, we'll dedicate the front HU channels to the tweeters (channels 1/2) and the rear HU RCA channels to the midbass units (channels 3/4). There are additional options for using the inline x-overs too, will have to address that if you decide to use them after all. If your HU has the option to set the front and rears for HP and LP, then set the fronts to HP at 6000 and channels 3/4 LP at 6000 and leave all the amplifier filters off except the HP filter on channels 3/4. Set the HP on 3/4 to the X1 position and the dial to get you to around 100hz (20hz is all the way to the left). This creates a bandpass filter of 100hz to 6 khz for the mids and a HP filter with a crossover point of 6K for the tweeters. If you don't have that option, then you'll be using the amps filters to create the same thing, a little bit different and if you're not familiar or unsure, take it to a shop and flip them $50 to adjust the amps filters. If you're comfortable with adjusting the amps filter settings, here is my recommendation. [B]Pay attention to the amp markings as the channel 1/2 RCA input is top and bottom left even though the controls are the top left to right. RCA inputs 3/4 are on the right, top to bottom and the controls are on the lower of the two, right to left. Keep this in mind when wiring up the speakers too, 1/2 will be the R/L tweeter and 3/4 the R/L 6.5's. (The red RCA usually designates the right side and white is left)[/B] Channels 1/2: You will set the the LP filter to "OFF" and HP filter to "ON" and the "X" times switch to the x10 position. that gives you a crossover range starting at 200 Hz up to 8kz so you'll want to start it with the dial adjustment all the way to the right at 8000 Hz. 200hz to 8khz is a really wide band and you'll need to be careful but turn it on all the way to the right to start and gradually make your way left, maybe the 3:00 - 4 O'clock position. Given the range, it's probably pretty sensitive and will not need to be moved a lot, you'll have to gauge it. Channels 3/4: This s a little trickier as your 6.5's are really pro style mids with a frequency range of 100-15000 hz so I'm going with a bandpass option, 100 to 6000 hz. On the midbass driver, you could work with the settings for the top end response in the 6-8k region, adjust to taste. For channels 3/4, you will set the the HP filter to "ON" and the "X-times" switch to the "X1" position. That gives you a crossover range of 20 hz to 800 hz. (passes high frequencies starting from 20 hz to 800 hz depending on the setting you dial in) Set the dial to about the 12 O'clock point, dialing it back (left) to around I'm guessing around the 8 - 10 O'clock position trying to reach that 100 hz point, you'll want to listen at moderate volumes and determine if they start to distort when there is bass material, then dial them further right a bit, thinking that 9-10 O'clock may be that position point. For the LP filter (passes all frequencies lower than the desired x-over point), you will set the the LP filter to "ON" and the "X-times" switch to the "X10" position. That gives you a low frequency pass range of 2 khz to 8 khz. Start it at the far right position (8kz and dial it left going from a high end of 8 khz down to optimally, around 6 khz. Set the gains for optimal output just short of clipping for both, not a fan of trying to eek out a few extra watts by allowing the amp to momentarily clip (ever), not worth the risk, especially if you're not a seasoned pro and know how that can be done successfully.
