    Hi there, i have a 2005 lexus rx330. i want to replace the front speakers. i know that they are simple 6×9– just a woofer cone. i want to replace them with 2-way speakers or 3-way 6×9 speakers. my question is, will i get the highs coming out of the new 6×9’s, or will the highs be filtered to the separate tweeter that comes standard in the lexus? do you have any details of the specs? maybe even amplifier specs?

    Renee, most late model vehicles do not have aux input on the back of the factory car radio. You will need an automotive aux input adapter. This adapter will allow you to input any Apple iPod, portable music player or mp3 player into your factory car stereo. This is the easiest and most cost effective way to add an audio input into your factory car stereo. Here is the adapter you will need:

    If you’ve never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2005 Lexus RX330 aux input adapter installation.
