I not sure you fully understand, I don't have ANY of the OEM electronics. I have a Clarion front end that has Bluetooth, Sirius XM etc.... So yeah I have full control... My sub is run through the Sub pre put of the Clarion, etc... I'm sure you have more flexibility in adjusting your sound with an active crossover though. Look forward to seeing and hearing it. Will you have the sub done for the Rally?
