New to the forums/ planning build

[Beavis]

Hi I'm new to these forums and just recently got into car audio. I currently have 2 12in mtx's in my 2003 3 series. I'm getting a new car soon, probably a chevy cavalier or other small two door car because my Beamer has almost 200k on it and its turning into a money pit. I'm looking to do a much more serious build for my next car, I was thinking about doing a wall with 4 15s. I'm currently looking at sundown, but I'm open to anything around $500 a woofer. My goal is basically to have as much bass as possible in a daily driver. I've read some threads about builds similar to what I'm planning to do, but I still have a lot of questions. Mainly to do with the wall construction, I know using mdf for boxes is common, is that what most people use for their walls? I also saw a few builds using birch, would this be better to use? Also, I was wondering about what kind of head unit to get.

I apologize in advance if I am posting in the wrong area or making an other noob mistakes.

Welcome to the forum. You have plenty of options a $500 a sub. Sub choice also depends on how much power your planning to run. Lots of good HU's out there as well. Are you looking for single din or double? I have never built a wall so I can't speak to that.

[Beavis]

Single or double din doesn't really matter, but I'll probably go with a double din. I'm looking to do a 4-5k watt system.

[Smoove]

5k would be perfect on 4 Sundown X's.

hmm if you was willing to get 12k watts you could do 4 Fi sp4.. they are cheap till tomorrow

your budget for subs is really good.. for the amount of power you want to use you will spend even less than the $500 you have per sub

Unfortunately I don't have money free right now, I just want to start planning things out so I can start sound deadening, working on the box/wall... Also so I could have a total price to work towards. I'm reluctant to buy anything until I actually get my new car. I think I have decided on 4 of these subs

With 2 of these amps

How many/ what kind of mids and highs would I need to go with these woofers? It would be nice to do an all sundown system, but I've heard good things about crescendo also.
