You guys are making a real meal of this.
Just bias the 5532 to half the supply with a resistive divider and use decoupling caps at the input and output. If you want you can use inverting configuration (simple, no additional caps) and if you're fussy invert it twice.
It's for car audio not hi-fi so don't fuss too much about which caps you use. A 16V 47uF tant across the supply will be fine, it's only an opamp and you've got a car battery backing it up.

So you mean that using 0805 SMD multi layer ceramic caps won't hurt? I will make some experiments I think, I want to hear it 🙂

Good compromise of size vs quality.
(For some reason WIMA calls their MKTs MKS).
But as so eloquently put above 🙂, don't sweat it too much for this application.
I would still try to have a decent filter or filter-regulator on the power supply though. All kinds of nasty on a car electrical system.
