So i just got my 2004 ls430 and I am having an issue with the radio (at least I think its the radio). when I start the car the radio would randomly come on for a few seconds sometimes even 5+ seconds and just cut off. after it does that it would start crackling and making poping sounds. I also noticed that the antenna has been ripped off (only the little screw part is in the housing and its stuck). another thing a Bluetooth transmitter wont work cuz the sound wont play, the calls cant be heard when I connect my phone to the car. but when I test the volume levels on the OEM touchscreen the little robot voice plays. I tried looking online and some people say it could be be battery. the last owner put a 650 cracking amp battery in there and online it says the car needs a 750-935 cracking amp battery (which I also assume cuz the car takes a few seconds to crank on and the battery in there looks a bit old). Anyone got any advice on whats going on?

if you have mark levinson , its probably the factory amp has failed. very common issue.
