Im looking to get one sub, preferably 10 inches and an amp installed. I work at best buy so i get discounts and my price range is around $450 for everything before discounts. Any ideas what to get? Ive never had a sub or amp in my car so this is all new to me. Im keeping the stock radio in my 2003 acura tl and id like to keep the stock bose sub going with the new sub too.
