My car currently has a Clarion double din DVD touchscreen, which I don't like. I find the dvd screens too distracting so I'm going to replace it with this JVC head unit ... http://www.jvc.com.au/car-av/head-units/kw-r700bt. Unless there is something drastically wrong with it, that's the one I definitely want. USB, AUX, bluetooth and a colour changer. Everything I want

There's an amp in the car already. It's only a 2 channel rigged up to the front door speakers. A Kenwood KAC-7204 which I was thinking about using for a sub or pair of subs and getting a new 4 channel amp for the speakers. A JVC (yes it's my favourite brand of stereo equipment lol) http://www.jvc.com.au/car-av/amplifiers/ks-ax3104
I did buy an amp from Autobarn the other day but I'm planning on taking it back. Buyers remorse lol It's an Option Audio OAK75. It was on special and it seemed like a good idea at the time.
I have 6x9 Kicker's in the parcel shelf - hooked up to nothing, and what sounds like nothing special in the doors. If it would stop raining for 5 frigging minutes I could take a look. PITFA not having a garage :/ There is also what I assume to be 4 tweeters, 2 on each door. My guess is the guy who owned this car before me just left me the crappy amp hooked up to the front speakers and took the good stuff with him

I don't have any sub/s yet. Was considering this ... http://www.ebay.com.au/itm/200892593061 ... 1423.l2649
If I get a pair (which I'd prefer) I'd like to go down to 8" or 10" max. Something along the lines of these ... http://www.ebay.com.au/itm/2X-KICKER-C1 ... 2c5ed7e306. I still want to be able to use the boot as a boot considering how hard it is to get shopping out of the back seat lol I can build a sub box no problem. When it comes to building stuff, girly I am not

So my question is basically will this work? Am I at least on the right track? Unfortunately when it comes to car audio I'm such a girl *shakes head*
Do I even 'need' subs? I love doof doof, especially dubstep, but mostly I listen to stuff like Megadeth, Alice in Chains, Stone Sour, etc.
Any help/advice would be greatly appreciated before I start spending money I don't yet have
