Well I got it all in there. Sounds darn good for an 8", I must say. Bout like I wanted. However, some people told me to leave any settings that up the bass, set to "Off". Well, I did leave the bass boost on the amp off. However, if I don't turn up the "Subwoofer" setting on my alpine CDA-9886 radio, then there isn't very much bass at all. You can just sorta barely hear it back there. I pretty much have to max out that setting to really be able to hear the bass well. The actual "Bass" setting on the radio, I left at zero. Anything wrong with this?
