My name is Grant and have a current system in my car, but now we are upgrading and trying to get ready for shows. Currently I have have mostly hifonics equipment except for amps. We are moving to 4 8" inch Jls in the rear cabin and 1 12" orion xtr pro in a vented box. Have 2 kenwood 2 channel amps for fronts and rears 3 kenwood amps for the 8's and for the rear 12. Looking forward to reading the product reviews and improving my knowledge as we move forward on this build. Thanks everyone for taking time to read this and look forward to your help along the way.
