Do not go to tweeter.....I am an installer at cartoys in mesquite,I do tons of jobs that tweeter started or just messed up........As an rx300 owner my self i know what will be best for you and your rx....You are gona need to spend some money to get better sound then what comes factory in the rx. I will beat any price you get from tweeter ,circuit city, best buy,Just talk to their installers and see for your self...More then likely you will get a 17 or 18 year old kid working on your car that is in training...lol...funny but not a joke.. you will be lucky get your car back in one piece ...I have been installing for 10 years and i know what will be best for you and your lexus....
ps i will beat any quote you get from any shop in dfw....please email me with any questions.....
