my speakers have dual crossovers two wires go in to one crossover then off to the tweeter the other 2 go to the other crossover then to the mids. at no point are two signals crossed as for amping its on dual mono circuits with twin transistor power supplies so like i said the signals never cross

i don't want to play mine is bigger than yours but 2k isn't really much to spend on separates these days. Basically if i disconnect the wire for the mid woofer the woofer will not work!
as for richer sounds

in a few years they wont even be selling the kinda kit you will want to replace the acram! (they are pretty little league in the world of an audiophile! its fun to actually make them squirm with difficult questions

)
Btw what amp is it in the diva range you have a65, a80, a90?
My mate is running an a90 coupled with the p90 on a set of jmlab chorus 726's sounds really really nice!
do you find the quads a little lacking on the low notes? i auditioned a set of 12l's and was really impressed with the midrange but eventually opted for floor standers to get that extra bit of extension and depth
like I said I don't want to get in a mine is bigger than yours match it just brings down the moral of the forum I was only making a point about the picture you posted.
In car audio we tend to not bother with bi wiring from just one amp! The norm these days is to use a 3way inline active crossover on an 18 to 24db slope and amp each range e.g. an amp for the highs one for the mids and one for the lows this gives us the ability to have massive range for tuning to get over the acoustic issues of the cabin in the car.
In most cases we have to play about with phasing to alter and lift the image. If you want to question anything on car audio I suggest you become a member of talk audio and join the iasca or the emma as there is a huge wealth of information available form its members.
have a nice day and dont take this as an attack! if you want to talk about audio then im on msn and the above mentioned forums.
