What, exactly do you have right now that resembles a system? I've seen some pics you posted of what looks almost like a boom box type thing, you mentioned Andrew Jones and Sony speakers, an Onkyo receiver, an amp, a humidity damaged subwoofer, some old kabuki speakers with rotted surrounds that look like an 8 year old tried to fix with toilet paper and elmer's glue and then you wanna pop different sized car audio drIvers in there... You're all over the place man. This isn't the type of forum you come to with disaster projects and ask if they can be salvaged or Frankensteined together out of parts from 5 different systems with caulk, glue, foam plates, bailing wire and bandaids.
Some of the questions you ask and the projects you propose are so preposterous it's to the point that I can't tell if you're being serious or just bored and trolling us. What's your deal? Are you wanting to get a sound system put together and need advice? Or are you just bored and looking for someone to talk to? What exactly do you want? We need a budget and goals. A realistic budget and realistic goals. Then you need to stick to your guns, save what you need and buy it.
Plus it helps if you read the replies. I thought BMX was very nice and did a pretty thorough job explaining something to you, and you just fired right back with the same question as if you didn't comprehend anything that was said. C'mon dude. Help us, help you...
