Hey people are now almost finished with my system and want to thank you for all the tips from you! But on a tip I would have heard or had to be informed earlier about it. And I bought more than 2 months ago a “1200Watt case” subwoofer for 110€ at Ebay! Pustekuchen – that has maybe 600watt and is really shitsssse. But since I want to end my suitcase space expansion soon I want to make a better sub! As FrontSys I have there s PX130 from audiosystem! Which sub would fit well with that? Price limit: 200/25€ – and it should be a housing sub!!! mercy
