By-Pass and Crossove Settings for Amp??

I am a newb at this car stereo systems and could use some advice. I just put in a new system in my 93 Volvo 940.  My Kenwood amp is driving the front component Kicker 5.25 speakers on channel A and my rear Kenwood 6x9s on channel B. I am using RCAs directly from my Kenwood Excelon 579 HU. Nothing is bridged and I don't have a subwoofer yet.  Currently the amp is set up with NO high or low filter pass settings and the crossover at the max 200 setting.  My questions:

What filter by-pass (if any) should I use?

Should I use a different crossover setting?

When I add my subwoofer with a second amp, I know to set that amp with a Low By-Pass and 100 for the crossover? 

Any advice is appreciated. Thanks

Is your amp a 2 channel amp or 4 channel amp, I would summise that it is a 4 channel amp. In this case you may want to use the High Pass Filter (HPF) on the front speakers. For now the rear speakers can be run at full range if you like or they as well can use the HPF. Is the crossover adjustable or is it at set frequencies? If it is adjustable then you may adjust it to the speakers that are run on the channel.

Disconnect the rear speaker rca cables from the amp. Turn the gains all the way down on the amp, turn the bass and treble on the deck to center position, then turn the volume up to about 85% of full output. Start to turn the gain up on the amp until you hear the speakers start to distort, then back the gain down a bit. When this happens, play with the crossover point up and down and you will hear how the crossover point will affect the performance of the speaker. If the speakers are distorting, the crossover point is too low and the gain may be too high. Do the same thing for the rear speakers, expect the rear speakers to be able to play more bass response than the front speakers. The idea behind the crossover is to protect the speakers from damage due to distortion. Reconnect all rca cables and have a listen, if the front speakers cannot be heard over the rears, turn the rear gains down.

Rob, Good advice, thank-you. Yes, it is a 4 ch amp. The crossovers are adjustable. I will play with it this weekend using your guidance. I do appreciate the good words.
