Just make sure the Amp's impedance & RMS match the subs " ".

How much would all that be at one time I wanted to buy this Shield ported sub box for extreme 600 to 1000 W kicker in the trunk but it would fill the whole trunk up and put a strain on the electronics for sure. But that would probably be a little too much considering it already sounds good stock what I love about these cars
If you have the ski pass that allows you to open the middle of the back seat to the trunk, then you have a lot of options.

You could add a corner mounted 10 or 12" sub like the link below. I bought this one & it's 100% fiberglass, which is excellent for bass reproduction. I believe it's much better than the any other material that is used for making sub boxes. I think mine cost $185.00 or so

You buy the sub first that you want & tell them the exact make & model. They will build the box according to the model sub you are putting in there.

You could get a JL Audio 12" sub w/ an RMS of 500watts for $309.00

You could get an Alpine 500w RMS @ 4ohm amp for $429

Box - $200
Sub - $309
Amp - $429
Amp hook up kit - $75.00

$1000.00- a little sticker shock for ya !

However, given the small size of the e90, this is MORE than enough power & bass for this size of a car! Trust me on that!!!

Personally, this set up is in the "base head" category. At least IMO.. 😆
