<human>: Give me the gist of the text in a nutshell

My car is a 94 integra and it's been stolen 4 times! Everything I leave in there gets stolen. The stereo is the stock tape deck and has been yanked out but wasn't taken. So I just pushed it back in. I originally took apart one of those cassette to 3.5mm adapters apart and wired it directly into the deck to try to eliminate the buzzing but the whole thing sucks and now I want to get creative. ;)  Anyways, I want to get an amp small enough to stuff into the deck ( I will be gutting it ), or at least have it be small/discrete enough to be hidden behind the dash as I will still be running the aux cable in through the deck to just make it look like a cheap adapter.
<bot>: Car is a theft hazard, looking for tiny amp to push audio from phone to car speakers but keep stock deck looking janky enough to deter theft.
