I used to have a kenwood one in my truck. I liked the bass knob plus you can adjust subcrossover points as well as mids and I could have done tweets if I had another amp. I bought an alpine 7856 deck and it doesnt have the **** eq like the pioneer, plus I have that stupid half din filler plate in my dash screaming to be filled with something. I was also looking into adding another 4 ch amp so I could adjust the tweets as well. I think it would be great to be able to adjust all of my drivers levels and crossover points from up front, what do you guys think? I was going to try a profile one from woffesetc for $49, Are there better ones? Or will it just add noise and distortion. Thanks, Chuck
