Do you agree?

The great part of that kit? The brackets to mount the amps. That said, without the brackets, you can buy all of those things separately and for less. Also allowing you to pick what components you want.

The foundation to that kit is the CL-SSI piece. That takes the speaker level wires and sums them as a single audiostream and converts to an RCA output for your amps. This is the piece you can buy better or stick with this. I have this piece. It works and is solid.

Then also buy the amp you prefer or like. I have an alpine 5ch amp in mine with the Bavsound speakers.

I do love the JL Sub though, their 10" sub is pretty awesome for the X5.
