Bridged amp question

I have a Memphis 400.4 six five series bridged to focal k2 es 165k in front. 1 and 2 to left 3 and 4 to right . Useing the passive crossovers. Question how can put the tweeters on say 1 and 2 and midbass on 3 and 4. With crossovers given with focals .
 
You can take apart the crossover and turn it into two separate parts, one for bass, one for hights.

With HIFI speakers, if they have 4 binding posts the rear, usually bridged with some metal part, you can use two amps to drive them.
That is called Bi-amping. In most cases, if identical amps are used, this doesn't give any audible advantage.

In your case, you will loose 50% of the bridged amp power, so when it is 1x200W bridged, you end up with 2x50W single ended.
Your amp will sound more stressed than in bridge mode if you ask me. Stupid idea.
 
Gotcha was just curious. Have it bridged left, and right quick over asked question why are my tweeters so bright tried eq and reverse polarity still high pitched. I'm using hu crossovers at 125hz with 12 db slope and crossover is -3
 
You can try a couple of things to reduce the tweeter level.

A series resistor will decrease the output but will also lower the crossover point. This shouldn't be a problem but could alter the sound slightly, especially if there are compensation networks (which I don't see on the drawing).

An L-pad on the tweeter shouldn't change anything but the output level if the L-pad is the same resistance as the tweeter.
