john253a Posted July 24, 2012 Report Share Posted July 24, 2012 unless you have more space (and able to give the port clearance) i dont think youll fit 2x 15 you could do 4 10" in the same space and have more cone area if that is something your interested in Link to comment Share on other sites More sharing options...
Crandis16 Posted July 24, 2012 Report Share Posted July 24, 2012 sorry, I just did the math 3 times too and I got something different ( 36 x 22 x 20) / (12 x 12 x 12) = 9.167 ft^3 I just woke up so I apologize if I'm wrong My Red zx2 Build Log My Black zx2 Build Log My Red zx2 UBL Link to comment Share on other sites More sharing options...

john253a Posted July 24, 2012 Report Share Posted July 24, 2012 20h x 22d x36w yes it 9.1cuft of area but 7.57 cuft gross with 3/4" mdf but you need to allow clearance for port unless you do port up with a 3.5" port youll need 3.5" of clearance leaving you with 18.5" d @ 6.5cuft gross after a double baffle front 6.3gross Box gets small pretty quick so with a tune of 30-33hz you only have 4-4.5cuft net to work with Link to comment Share on other sites More sharing options...

b-dubs89 Posted July 24, 2012 Report Share Posted July 24, 2012 my 1 set up for the last couple years has been a pair of jl 13w1 subs running 2ohm off an mrp-m500 , in a sealed box and i thought the performance from this package was pretty alright .if space is an issue i would start thinking about making something out of fiberglass to maximize the space available . being a hatch car it shouldn't take too much to get some volume Ok cool. Fiberglass is an expensive option but well worth it I have heard. Clean looking and soild if done right. fiberglass is kind of expensive , but when you think of $100 dollars for a prefab box that makes the supplies for fiberglass look like more of a value , $45 for a gallon of resin and $30 for a big chunk of glass mat .a gallon of resin can go a little ways if you know how to work it .i guess for the expensive part of fiberglass has been learning how to do it .

notorious97200 Posted July 24, 2012 Report Share Posted July 24, 2012 Just buy a good 15" sub and a build a ported box (32 Hz tuning, don't need to go lower). You have 1000 w rms to play with. It is not a lot of power, but you can have good results with that power. With that budget, you can find a used Fi btl or a good DC sub. You will upgrade your amp later, but it will sounds good even with "only" 1000 watts. black BMW X1 2.0 l 192 hp OEM head unit, Amplifiers : Audison AP 8.9 amp with integrated DSP and Ampere Audio 1200. Focal ES 100 K in front doors, and Dayton RS 180 for midbass under the front seats. 2 SSA DEMONS 10" subs, in a 2.6 ft3 ported box. SecondSkin Damplifier on front doors, and Luxury Liner Pro for the cargo area. Link to comment Share on other sites More sharing options...
john253a Posted July 24, 2012 Report Share Posted July 24, 2012 Fist ground pounder requires cone area and a single 15" has less then 2 12" Second he only has 500w x2 not 1000 So he need 2 subs as he can't strap them amps What ever he choses need to work within 4-4.5net as a total Options 4x 10" on 250rms Ea 2x 12" on 500rms Ea 1x 15" on 500rms If you can get a bit more space 2x 15" will work Link to comment Share on other sites More sharing options...
Cashdollar2009 Posted July 25, 2012 Report Share Posted July 25, 2012 Spent about 30 seconds vaguely crunching number in the Torres calc. You can fit two Sundown SA-15"s if you wanted to.
