I have a 06 Charger SRT8 with the 11 speaker Kicker system. The Service Manual does not address some of the speaker locations as built into this machine. This is okay as that changings speakers, if done slowly and methodically can be done without damage. But, the real question before starting. The manual refers to DTC's that will set, it appears, if certain things are done. One being changing the main amplifier. (The manual does not address the SRT8 separate Sub-woofer amp.) It appears that a B221F may set. Also, each speaker is also monitored and each appears to have a separate DTC's. So, does anyone know if or what conditions will trigger a DTC? And, does anyone know a way around the DTC's?
