Default 2-way Front stage, active, 2 amps questions

I have 2 JL Audio RD400/4 that is going into my truck. The plan is to bridge each amp. What is the appropriate way to connect the front stage? Driver's side to one amp and passenger side to the other? Or tweeters to one amp and mids to the other? Thanks in advance!

Tweeters to one and mids to the other... but that is a lot of power for a set of tweeters. You could get away with bridging one to the mids, and using the other as a 4 channel with two channels for the tweeter, leaving you with two extra channels for whatever.

doesnt matter, but i would do drivers side on one, and passanger side on the other. reason being is to 1) not put most of the draw to one amp (midbass will pull much more current) causing one to heat up a lot more than the other, and 2) better left/right separation in theory.

Honestly, that's a lot of power for even mids even though many do it including me. Mainly I didn't want the extra channels of a 4 & 5 channel amps going to waste on a 3-way + sub. Basically, that's enough power to run a 3-way+sub if chosen right. Above sub frequencies we don't use as much power as you think for common listening levels.

That's enough rambling...

It doesn't really matter, whatever you want. I have one bridged on mids and one running two channels only on tweets, leaving two channels free. One of these bridged on tweets seems like overkill, and maybe too much.

I would do 1 amp for mids and 1 amp for tweets unbridged on the tweet side. My reasoning is you'll be able to keep the gain allot lower on the tweets and you'll have less noise. For me my tweeters have a tiny hiss when my volume is at 0. I only hear it if I get close to the tweeters but if my gain was where my midbass gain is it would probably be worse.

With all of that power and 8 channels I'd find a way to make it a 3-way front.Bridge the midbass channels and run the mid-range and tweets off the other 4.

In my case, that is the final goal. One amp bridged on midbass, the other amp for tweets and mids. Some of us just take one step at a time, as opposed to putting the whole system together at once.
