I did the Dsp Bypass thing.

And it worked fine. I did loose my DSP as decribed in that thread.

It my understanding that the RF 360 , JL CleanSweep and AC LC8 all do channel summing as well as EQ flattening. So wouldn't the above products eliminate the DSP anyways?

I was going to go the summing route but the cost and time for a worse sounding system just doesnt make sense.
If you really want an EQ, get a trunk mount one like this.Much better than factory DSP EQ.
