So I plan on taking advantage of the SAZ-1500D sale this month and I am going to need to decide which sub(s) to purchase as well. I'm looking for a little guidance in this respect.

I own a trunk car so I'd like to keep the size of the box down if at all possible - I'm thinking under 3 cubes. So that probably leaves me with either one 12" ported, or 2 12" sealed. I guess I could do 1 15" sealed too.

I listen to mostly rap, so SQ is of little concern, but I don't want it to sound like complete crap either, at least to me. I have been thinking of either a 12" BL or 2 12" SSDs. However, I'm definitely not firm with these choices. I'm looking for recommendations. Again, looking for something to get loud, but not a fart box either. I'd like to retain some musicality I suppose for those rare times when I do listen to other music.

Thanks guys. Once I get this part locked down, I'll be looking for more help with the front stage.

look into the Icons in the SSA part of the fourm, there pretty decent subs

I'd do 2 12's sealed.

2 12" Icons sealed sounds like a good plan..

^^that it does

never heard the icons so i can't comment, but a pair of 12" Qs would suit you fine, or SSDs. A pair of BLs might be underpowered and running a single one may leave you wanting a bit more (i'd talk to someone @ fi about this). The icons should perform fine and you could also go with a number of used subs.

What is your budget? I have (2) 12'' Infinity Kappa Perfects for sale for $150. You could wire them for 2 ohms off a 1500 with the gains set responsibly.

I had thought about the Icons, but I thought I heard they are out of stock until August. Unfortunately, I'm not that patient and will probably be ordering something in the next week or two.

So I think I'm going to go with one of my original choices - either a single 12" BL (ported) or 2 12" SSDs (sealed). I only have experience with sealed woofers, so I don't even know what a ported box would sound like. But from what I hear, I might enjoy the sound of a ported woofer.

I understand that it's install dependent, but do 2 12" SSDs sealed have the capability of getting louder than a single 12" BL ported, in ideal boxes?

honestly with what you've described i would recommend ported as well.

two 12" SSDs sealed could be louder, but they might not be too. a single 12" BL ported a little high would probably beat them out and have more of the sound you desire. I highly recommend finding someone close to you with a setup that you could hear.
