can I (or would it be wise) to run a channel off the amp to each woofer and each tweeter individually? i have a 4 channel kicker KX650.4. here are the specs:

Power (WATTS/CHANNEL), 2 Ohm Stereo: 170W x 4
Power (WATTS/CHANNEL), 4 Ohm Bridged Mono: 325W x 2
Frequency Response: 20Hz-20kHz; +0, -1dB
Input Sensitivity: High Level 340mV-10V, Low Level 170mV-5V
Active Crossover: 12dB/Octave, variable 50Hz-200Hz, selectable high pass, low pass, or all pass

here are the specs for the morel dotech comps:

SYSTEM SPECS:

Nominal Impedance 4 Ohm
Power Handling 140W
Max. Transient Power Handling 300W
Sensitivity (2.83V/1M) 90dB
Crossover Point 3200Hz 6dB/octave

DOTECH MKII 6" WOOFER

Nominal Impedance 4 Ohm
Power Handling 140W
Max. Transient Power Handling 300W
Sensitivity (2.83V/1M) 90dB
Frequency Response 40-4000Hz
FS 57Hz
DC Resistance 3.2 Ohm

SPECIFICATIONS MT-11 TWEETER
Nominal Impedance 4 Ohm
Power Handling 80W
Max. Transient Power Handling 250W
Sensitivity (2.83V/1M) 91 dB
Frequency Response 1800-22000Hz
FS 950Hz
DC Resistance 3.4 Ohm


I WAS THINKING THAT AMP 1 (CHANNELS 1 -2) and use them to power the tweeters. I could then use AMP 2 (CHANNELS 3-4) to power the woofers. That would allow me to set the gains for the tweeters seperately from the woofer gains and I could control how the highs more effectively, considering my head unit (alpine 9856) has a poort excuse for an EQ.

I am no expert so if I am wrong, PLEASE tell me. I am getting them installed tomorrow and this just popped into my head.

is there a passive x-over with thoes speakers?

would require an electronic crossover of some sort but yes it would work

here are the specs for the crossover that the comps include:

SPECIFICATIONS

SPECIFICATIONS MX-20
Nominal Impedance 4 Ohm
Power Handling 150W
Crossover Point Power Handling 1800Hz 6dB +12dB/octave
Crossover Controls Tweeter Level: -3dB, 0dB, +3dB
Wiring options Standard

thank you for telling me its possible, but would it be wise?

i guess they are not ready for bi-amping.

yeah it would simply be an active system as opposed to a passive system

Yes the drivers are available seperately, but I just looked em up and its cheaper to just buy the set and not use the crossovers. Not to mention its easier to sell the set when that time comes as a passive.
