what would you reccomend for a crossover(s)...i have one four channel amp and two mono amps...the mono amps will be at different frequencies..one for 10s and one for a 15. the amps have crossovers, but i imagine i can have better control with an external crossover...i am also considering an epicenter...probably for 10s? not sure yet...i know i want one for the 160spl in dash meter, but im not sure which sub(s) to hook to... that was a mouthfull!!!! what are your suggestions?

Holy bad habits. If you are using a Epicenter it will affect only the 15's. I would recommend a Audio Control crossover, probably the 4XS to do the job. The epicenter is the first processor in the signal chain, it goes before all crossovers and equalizers.

What do you hope to accomplish by running a 10 and a 15?

i want the 10s to hit the mid/low bass with clarity for rock etc, and i want the 15 for the ultra lows with rap, bass cds, etc. that rattle your eyeballs!

OK, what you're looking for is something like the Audio Control DXS crossover. This is a three-way digital Xover with 24db/octave slopes and some other interesting features. You do not want the Epicenter for this application. With a DXS (or a similar three-way crossover system like a JBL GT47X) you send it a stereo signal from a main pre-out off your head unit (the rear channels, for example.) Use the low-pass output from the DXS set at, say, 80Hz to drive the amp you use for the 15. Use the bandpass output (NOT the same as a bandpass enclosure!) from the DXS set between 80Hz and oh, say 250Hz to drive the amp for your 10. Use the high-pass output from the DXS set to 250Hz to drive the amp for your rear channel main speakers. Will this make much difference? You will probably notice a better bass response in the bandpass frequencies since a 10" woofer will be much better between 80 and 250 Hz than most smaller main speakers.

Use your front pre-outs for the front and rear for rear you have fade control. Use your sub out to feed the DXS and don't use the high-pass output.

ok...so the DXS would only take care of the subs? why wouldnt i want the epicenter?

You don't need toys like the Epicenter if you're running a 15" sub. You will get REAL bass, not synthesized bass.
