Hi there,
I am the proud owner of my first Lexus, only a month old to me. I have a Toyota Supra as a weekend car, however i am enjoying the drive of my is300h after upgrading from an old Astra 1.7DTi as the daily. I have looked over the forum and tried searching for the answer, however it doesnt seem to fit my problem. I like the entertainment system, however it lacks any real depth. At first i thought the car came with a sub on the parcel shelf, however on further inspection, it just has a cover in place where the speaker would be for the prem nav spec. My question is, is there any wiring loom which i can come off from so that i can install an external sub box and amp. I have read that some people have used a rear door speaker output and fed this into a high input on the amp. Just wondering whether the cabling would be tucked away somewhere that i can use? Any help would be appreciated.
