Find a modern bass box 25-30cm Sub

Hello everyone. I have recently come back to the funnel to bring some fresh wind in the car-hifi area of my vehicles. And I am looking for a bass box in the 25-30cm woofer area for my second car, an Opel Astra G. I unfortunately stopped making me smart in this sector in 2000 which is further recommended on the market. If you could maybe suggest something to me that makes noticeable bass. I thought about a normal case, not band pass! Price so 100-150€ new, or used so up to 80€. The whole is driven by this power amplifier 4 x 70W RMS, bridge 160W Rms. So rather not hi-end. Should bring some level. Thanks first in advance!
