yeah that is the correct size, I replaced mine with a 10" alpine type R-Thin took a bit to do but it can be done, regardless of weather you put in an 8 or a 10 you usually have to do some modifcations to the support where the sub goes. I can send you pictures if you need me to.
btw your going to need some sort of sound processor or at least a LOC to get anything to work properly and amplify it.
This is a LOC *they are cheap and decent quality but doesnt fix the sound from your headunit*: http://www.davidnavone.com/cart.asp?24&cat=7
Thanks for that. Reading about the AudioControl device, it looks like a PITA to install. Mapping wires, mounting that thing somewhere out of the way, THEN adding your equipment after all that just to get some decent sound from the RCA's... wow.
well thats what you have to do to make it sound professional in my opinion... its a lot easier then doing all of that work then using sound controllers and tuning the sound yourself in my opinion I really wish I would have taken pictures when I did it all, it really isnt all that difficult in my opinion... takes about a full days work to do.
basically if you wanted to theres a pioneer sub you can just plug and play with your current subwoofer and I believe you can get a little bit more punch out of it, but really I believe that the problem is most people just want noise... If you want it to sound friggin tits you gotta use a sound processor. If you just want noise wire in a sub and amp from your wires in the back of the powered sub and have at it. will take you twenty minutes to do probably.
