8 Speaker Amplifier Info

[jfulks78]

Hello everyone! I have scavenged the net looking for information about the factory amplifier installed in these vehicles and I have been unable to find ANY useful info. I have a 2009 RX350 with navigation and without ML.

I want to upgrade the factory audio system (head unit, speakers, sub) but I cannot find the output info on the factory amp to help me decide if I want to keep it or upgrade it. I would like to know the peak and RMS wattage of the amp. I would also like to know, if I upgrade the amp, would I still be able to add the steering wheel adapter to the install and retain usage of my steering wheel controls. I would greatly appreciate any info!

Thank you in advance!

^{Have you physically checked the amp, itself? If the info you seek is not there, you may be able to contact the manufacturer or distributor.}

Hi Jon and welcome.

There are a couple of places to look for your information. The easiest one is to ask your dealer. Some may not be thrilled by this but will help a good customer. Another choice is "Toyota Information services". This is an official Toyota site covering every technical detail on all models of Toyota, Lexus , and Scion. Log on to TIS.com and register. 2 days of access is $15.00.

Let us know how things turned out.
