How do i dissable the passive crossover in my Rti a9 so I can bi amp them?

I will be using a Crown xls 2500 for the woofers and an xls. 2000 for the mids and tweeters so how do go about making this happen? I am not talking about bi wiring I am talking about bi amping

Hello,
In the interest of answering your question, you would have to remove the speaker's passive crossover and disconnect the wires coming from the internal crossover to the tweeters and drivers. Then you would have to replace the backplate with another plate that would have connections for the tweeters and drivers and run corresponding wires to the speaker's components.
Then the hard part. You would need a very sophisticated active crossover that would have adjustments for high pass and low pass filters, including frequency adjustments and be able to adjust the slope of the high and low pass filter points. And do this with minimal THD and IM distortion and phase errors.
The real problem is that today's high quality speakers have much more carefully engineered crossovers than older speakers. They often have impedance matching circuits tailored for specific characteristics of that speaker. A great deal of the speaker's quality happens because of the care the speaker's designer uses in developing the internal crossover.
The advice given by other CP members is right on the mark, the benefits of removing the crossovers are far outweighed by the potential for a result not as good as stock.

Honestly this is why I am asking, because I do not know how to do it. I would like to know how to dissable the passive crossover in my speakers and run an active crossover hooked up to 2 power amps. I believe the difference would be drastic but just not sure how to do it

May I suggest listening to the speakers without the modifications to get a baseline on how they sound. Later on down the road, perform the mods so you can compare.

I like the KennethS post above. Biamplification is useful for pro audio in some situations but it really isn't recommended for home audio. The speaker designer probably did a better job of getting the most out of the individual drivers than you would.
