i think u made a big mistake by going for a 3way system with your current setup .....u should have gone for 2 way .....
in a car environment in order to get a good 3 way u need a lot of EQ adjustment for your mid as a mid require an enclosure and most of the time d installation of mid in car couldnt give u d enclosure u need .....most of the time, its highly recommended that to play 3way in full active system ....

i think the easier way is to ditch your back speaker ....then change to a good HU ....if u wan to go for SQ the u should go for a pioneer 8650,9650 or p80r (if u still wanan stick to pioneer lar).....use the active crossover in these players n play semi active with your passive crossover.....the EQ in these players should be enough to control your system ....try these first before u change your amp .....your system sound very bad now is cos of a wrong setup for SQ .....i have heard of a Prokick setup that sound quite good.....a good HU with a very well balance setup could make an amp shine even if the amp is lousy .....

yupe.....d 8650 n 9650 can only go down to 1.6k but u could try using d the mid and midbass together .....u can use the passive internal crosspoint for the mid and midbass and use the tweeter as the active......but this way your mid and midbass have to quite close together ....it good for mid which is at kick panel ........the lowpass filter for the mid bass range from 1.6k to 16k....

yupe ....like they say ...3 way is d hardest to setup ....semi active is when d player can support only 2 way system ....

in a 3 way speaker ....it consist of
2 tweeter
2 mid (the smaller speaker)
2 midbass

example .....for a HU that support 2 way active system ...there will be 3 pair of output from the HU .....1 pair is for d tweeter , 1 pair is for the midbass and 1 pair is for d subwoofer.....there is 2 different ways of playing semi active ......

first one is to use the tweeter output to drive the tweeter and the mid in this way u can control the high pass of the mid .....the crossover point of the mid and the tweeter will be determine by the original crossover......then the midbass will be controled from the midbass out from your HU

the second way is to use the midbass output to drive the mid and the midbass together ....this way the tweeter will be fully active.......

if u wanan run 3way full active then u have to either change your HU to a better HU or get a processor such as d Alpine 700,701 or the 900.....
