Hey guys ive searched around and I cant seem to find anything if there is a thread out there for this plz post the link. ive been wondering if its possible to upgrade meaning replace the stock subwoofer speaker between the back seats just to be clear I don't want to change the box I just want to know if it is possible to take the speaker (sub) that's in there out and replace it with another one if so what is the size and if not than what are some suggestions besides the tacotunes box because it doesn't fit 09 and up. Appreciate any info, Thanks
