Stereo Upgrade to 2006 Lexus IS250

[jsibayan]

SMD,

I have a 2006 Lexus IS250 with the factory navigation/CD player non ML Design type system. I want to increase the sound level in my current system. I'm from the Monterey County area a I went to my local stereo dealership and I was told that the Lexus IS250 has a digital sound processor that can not be altered if an amplifier is changed. I believe its the feature where I could isolate different areas in the vehicle to play music and shuts off the other areas for more specific sound. He stated that adding an aftermarket amplifier to increase the sound level, but it will make the DSP function inoperable, and I don't want that. I want my stereo to work like factory but I want it louder. Now, is this in fact true?

I am willing to drive up to your company and have a system installed to my liking if your company installs car stereos. Is there anyway, you or one of your representatives can give a number to call so I could discuss this issue with them or if you can provide me with any assistance in this dilema. I would like to get this done, but I don't want to alter the factory features built into my in-dash system. Please reply.

Thank you
