Installing aftermarket amp
 

Hi,

I've read on that people have successfully installed aftermarket amps with this car. I have installed many systems before but never on a new car. I looked at the firewall and I prefer not to drill through it. Is if possible to feed the wire through an existing hole that I'm not seeing right now? What's the best way to rub the wire? Also, will install an aftermarket amp/sub void my warranty?

Thanks!

Yes, it will void the warranty. I was prepared to have my local Lexus dealer upgrade the audio system which they assured me would not void the warranty but was satisfied with the amplifier 'fix' with the ML system. Do you have the standard system or the ML? Either way, you should discuss your concerns with your dealer.
