Qyn's Summer Moddin'... need advice

[Qyn]

I'm looking at doing some light work on my '05 Elantra, and need some advice. I want to do a CAI, sound in my trunk, and maybe a sway bar. I'm going to do something to my c-pillar covers, and am looking for ideas with that too. My buddy's dad has a home shop (FULL shop... dude has more **** than a Meineke... it's sooo dope), so I'll be doing all my own labour (labor for you 'Mare-cans).

CAI: How much should I be paying for parts? Saw some on Ebay... don't know what to buy (I know it's the Accord one, but brand? No clue)

Sound: Have a buddy that works at an audio shop (having hook-ups rules). I want to go all-Kicker in the trunk. was looking @ 2 L5s, 750.1 amp and either a custom box or kicker box. I'd like to be able to fit some **** in the trunk still... so I don't know.

Sway Bar: I'm gonna read more abt this, but still appreciate advice.

C-Pillars(the ones behind the rear seats): Purely looking for ideas of how to mod them. I busted one this winter 'cause I'm dumb... so instead of going back to stock, might as well mod! Maybe an EXD design?

I'm also gonna buy some EXD decals/badges, and debadge the car. I'm looking at chrome taillight covers (I kinda like chrome... so sue me).

note: If there is a better section for this topic, please put it there.

Thanks in advance for the advice/flame!

Brand doesn't really matter. most people get a 2 piece intake.

as for the sway bar, http://www.elantraxd.com/forums/showthread.php?t=13022

all you need to know.

Anyone have some advice on Audio equipment?

I have the possibility of buying a Sony XM-D9001 1300w amp for $180 Canadian (used).
I also could just get the Kicker 750.1 amp.

I want to get two Kicker L5 12" subs (New... never buying used Subs)

Anyone know what kind of $ I'll be lookin at for this?
