Ok Ive got a question for anyone who can answer. My amp has a crossover for the front channel and one for the rear. For my front crossover I have a choice between OFF and High-pass filter. For my rear I have a choice between High-pass, low-pass and FULL. The speakers I am using are coaxials, 2 way in the front and 3 way in the rear. How do I want to set my crossover for each? Im not adding subwoofers so I want as much Bass from my speakers that I can get without damaging them. Also, I have bass boost between 0 and 8 DB. How will that effect how I tune my amp? Will I have to set it and then tune my amp or can I tune it and then adjust the bass boost as I please? Any input would be appreciated.

if ur not adding a sub i would set the front to high and the rear to full.
i would get all speakers to sound as good as they can by tuning the amp, and then for the rears turn up the bass boost as much as u can.!

Thanks Josh. So for my fronts I set it for high-pass. The frequency response for my front speakers are 60Hz-25kHz. So I should set the crossover to 60Hz then? The lowest frequency my rear speakers are rated for is 30Hz, but my amp is rated for 20Hz as the lowest. Would setting my rear crossover to FULL still be OK or would it be safer to set it to high also and just adjust the rear crossover to 30Hz?

You definitely don't want to push 5.25" speakers to 60 Hz. Sure they'll respond at that frequency, but they'll have mininum output and you'll blow them trying to get much out of them that low. I would honestly not cross them any lower than 125 Hz if you want to play them loud safely.
As for the rears, I couldn't give you a good number since I've never tuned 6x9s myself, but just use your ear. If you hear them distorting, raise your crossover point a little until they sound clean again.
Generally bass boost is bad news. The best way to set the amp is to set the bass boost at zero and start with the gains low. Set your EQ on the headunit however you want it. Then, pick a volume on your headunit that you want to use as a maximum volume (like if your headunit goes to say 60, maybe choose 50 since it's a nice even number and your preamp outputs shouldn't be clipping at this level). Play a good loud song or test tone at this volume and then slowly turn your gains up until you hear distortion, then back them off a hair until the distortion is gone.
With your amp set like this, you'll be getting the most out of your system at that maximum volume you picked. Thus, increasing the bass boost and playing at that max volume will cause clipping (or overdrive the speakers, or both lol) and damage your speakers, so don't use it unless you're keeping the volume lower.

the full setting will allow full range of Hz. usually the low pass will max out Hz at 125 to 220. not sure what the high pass will be but if you use the high pass u wont get the low notes like for example it might go as low as 1KHz.
like Dbl_D718 said about the bass boost i would recommend setting the speakers the best you can with out them. then maybe add some just a little to get some more bass---providing the amp has a rational *** not a switch---
