I am new to this forum. I have two questions and would be grateful for any help. I have an 04 WRX that I am trading in for a new 09 WRX. My old car had the sub woofer and I am wondering if the old sub woofer will work in the new car. Also if the connector for the sub woofer will be under the seat without ordering the sub woofer kit? Any help would be appreciated. I know the factory sub isn't that great but I already have it so I might as well use it if it works. Thanks again.
