Built-in amp radio, infos plz Options

[dudeofchaos]

Previous owner removed the radio and amp from the car. I suck with electric stuff and correct me if I'm wrong but installing the Oem amp requires to take part of the center console apart.
I've heard of an Oem radio that had a built-in amplifier. Could I just simply get this model and simply bolt it, connect it and voilà? Or am I missing something?

Anyone knows of this model, is there only one kind of radio with this built-in amp?

If this works it'd save me up a lot of troubles.

Thanks!

I'm into OEM stuff, I hate aftermarket radios. I'd much rather have the stock head unit with the stock amp (or both in 1). My other Celica had a stock system and I loved it.
Last time I checked, it seemed to be a pita to reach where the amp sits. Anyways, I might get it installed.
At least I know it can work. Now I just need to know how to rewire, Idk if the plug will fit.
There is currently nothing in the car, no radio nor amp and wires.
