I would first like to start off by saying I know just about nothing when it comes to subwoofers. I am hoping to get some good advice and some answers from anyone who is willing to take the time and answer them.

​​​​​​​I am considering installing 2 12 inch kickers(Kicker 40CWD124 CompD 12" ) in my trunk. First off, are these any good? I don't need anything crazy but I want something that will hit hard. My second quiestion is if I get these, is 2 cubic feet good enough for both of them in a sealed box? And my last question is what kind of amp would I need? If anyone could link and exact one, that'd be greatly appreciated!

​​​​​​​I would like to thank anyone who answers this thread, as I am pretty clue less.

 

The subwoofer enclosure I'm looking at says it has 1.5 cubic feet. And the subwoofer says it requires a minimum of 1.25 feet, but since there is 2 subwoofers does this change anything? There is another box that is a little more expensive that has 2 cubic feet, would this be a better option?

 

go talk to an audio store... tell them what you want and see what they recommend.

 

are you needing any left over space to actually use the hatch

or are you willing dedicate the space to music

 

I wouldn't buy any sub that advertises 1.25-3.5 cu feet recommended per sub without a graph showing decibles/frequency to build a proper box. you need minumum 2.5cu feet for two subs.

 

All you need is 1 sub and a nice amp to power it... 1 decent sub will take up less space and require less of a box, and will still "hit hard"

I have a single 10inch in my living room that vibrates my entire house when I turn it up into hate my neighbor mode.

 

2 cu ft box = 1 cu ft per sub if you have 2 subs. The Kicker Comps are good subs and should perform fine in a box that size provided its sealed and not ported (vented). My guess is at 1 cu ft instead of 1.25 it will be tiny bit louder but not as deep (lower frequency). The nice thing about sealed boxes is +/-10% in size isn't a show stopper. Vented boxes are a different story.

As for an amp - bigger is normally better, but get one that is rated to deliver at least what the sub is rated for. Don't be fooled by marketing claims of 1,000!!! watts, get an amp that actually does it with proof (birth certificate, independent test, verified users, etc). Also make sure your ohm load is correct. Those subs are dual 4 ohm which means either 2 or 8 ohms when wired up. So two of them together will be either 1 or 4 ohms, so you'll want a mono amp that handles that load. Just remember the power will be divided among the two subs equal. Personally I would drive them with a 800 watt amp (400 per sub) in a sealed box and be happy.
