I currently have two JL Audio W0 10" subs in my car right now in a box. I want to replace these subs with new Alpine SWS-1042D subs. My question is - can i take my old subs out of the existing box and if so how hard is it? If they can be taken out would the new Alpine's work in that box? They are both 10" and are rated at around the same watts i think.
