If you like the sound of the current setup, but find it simply lacking in bass you may want to just add a subwoofer to the system.
Most stock systems are tuned to get the best response they can from the (often) very cheap speakers used. Unfortunately, the sound mostly falls flat at higher volumes as well which necessitates an upgrade for some (Hence where you're at now). I think you simply need a subwoofer to add to what you've already done.
