Thanks FastG. Well, I am starting with PPF install tomorrow. Window tint within two weeks. No immediate performance mods planned yet. Funny I literally just got off the phone talking with the audio install shop. Seems there are a few mysteries about accessing the audio signal from the factory head unit. My goal is active 3way front with a 12 inch sub in a sealed enclosure, and leave rear fill factory. Per the shops research it appears the Lexicon system uses full digital outputs, that get processed at the amplifier into 12 outputs. There are no easy adapter systems currently made, so they are going to have to take signal samples from the factory amp speaker outs. We will learn of the DSP input requirements after the testing. I pray I do not have to tap all 12 outputs to process. I have 8inch thin midwoofers (AD W800NEO) I hope they will fit in the factory sub locations under the seats, with tweets and mids in the doors. If the 8s will fit under the seats, I will be wide open for mid options. We may consider A Pilar pod options as well. I plan to feed the front stage with a Mmats HiFI 6150 and the sub with a ZED Minotour II.
If you come across anyone that has already done audio mods, please pass my way. I would love to learn from their experience. I will share feedback as I make progress.
