Wiring and subsonic filter?

As a suggestion, buy another identical 5 channel amp, bridge the bridge them each to 3 channel mode, and then you will have 4 very high power channels, and two remaining mono channels for running a pair of 4 ohm dual voice coil subs. If you are going to do this configuration, though, use one for one SIDE of the car and the other for the other SIDE of the car. This will keep your separation and imaging as high as the deck can put out. Also, with the four channels bridged to two channels, they will be seeing two ohms per channel. Forget all that drivel... I have to agree with DYohn on this one... Bridging quadruples the distortion rating, and quarters the damping factor, both bad things, indeed. Get more power than you absolutely need to start with, and have somebody THAT KNOWS WHAT THEY ARE DOING install it... and Eclipse does indeed make a wonderful 5 channel amp... the PA5532 is an amazing piece of gear, and not heinously expensive... Your Kappas would SING, then add a good quality sub, and you are done. Also this amp makes more power into the 4 ohm load of the Kappas than the MTX - 70 watts at 4 ohms, versus the 70 watts at 2 ohms of the MTX. <Probably around 40 watts or so at 4 ohms> Forbidden is also correct, a 5 channel amp can be a dream to work with... easy installation, and usually with all of the bells and whistles built right in...

I really appreciate the help guys. I have the MTX already and access to the JLW3v2(free). I haven't bought the 5X7's yet but the Kappa's are what I wanted. I'm trying to build a decent system with what I have already. If a 5 channel could be a good thing, then whats the best way to set this system up. I wanted to have this MTX run everything for now. Could I just run the 5X7's @ 4ohm and the sub @ 2ohms? I this possible? And if it is, is the worst case scenario just running a sub at 320 and 5X7's at 40? Really, thanks for the patience guys

Thanks, I hope so also.
