Okay, I know this has been covered before, but Ihave got a 08 Outback, with the factory 6 speakers, they are all Kicker, and the Factory Z.200 amp. Im satisfied with how the cabin sounds, but need t oput in a sub. Thinking 10 inch or 12 inch... not sure at the moment. At the drivers feet sound good, because I wont loose storage space under the observers seat. So... I want to replace the amp that I have, and get an amp that could also power the sub. (5 Channel I presume) What is a good amp that I should get. I need to d othis on the chaep, so no more than $200 for the amp on ebay. And prob $150 for the sub and box perhaps. Ideas?
