Subwoofer install

[Alfa-mad]

So I got this Pioneer subwoofer (model: TS-WX130DA) that is a bit different to the usual in that it's designed to be installed underneath a seat (you can still install it anywhere though).

Thing is, to install underneath the seat, it expects you to drill into the floorplan so you can secure it, but I don't want to go drilling into the car like that if I don't have to, at least not the main body, so can anyone suggest a way to secure something beneath a seat that doesn't involve drilling into the body?

Make up a bracket that attaches to the seat floor mounts and then attach speaker to bracket?

Ditch the sub woofer, fit a decent SS exhaust and wind down the window?

Actually, that's a good idea. I'll do some measurements and see how I go
