tri mode amping

   i have a kenwood kac7202 { 150 x 2 rms  4ohm,  230 x 2 rms  2ohm ,  460 x 1 4ohm bridged } tri-mode capable

      i also have a polk db6500 component set { 100W rms }  , and a mtx  thunder6000 (10in) 250rms

      i tried to tri-mode this amp but i dont know how to get the parts(inductor ,capacitors). so i went ahead and just connected it without em. the components sound the  same(components came with their own passive crossovers) as if the sub wasnt connected, the sub on the other hand is dissapointing me .  im looking to get something that will sound good with this amp ( im looking for a good sub with low enclosure volume)

     the kenwood manual states that  ""The capacitor rating should be as close as possible to 331.25 (ìF) and the coil rating should be as close as possible to 5.3 (mH).""

i would like some info if possible on tri-mode operation, what is the true rms for the SUB , WHERE CAN I BUY THE CAPACITORS AND INDUCTORS NEEDED (online)

< language=>postamble(); the kac7202 does claim to be trimode (manual and box). im not looking for another amp, i just wanna use the one i got ( space issues , rewiring issues) .

thank you stevdart for the links
