Sub Choice
Trying to decide on which 10" sub to get. This sub is going to go in a storage compartment in a C4 mounted in an MDF "lid" sealed to the top of the storage compartment. Amp is a Alpine single channel MRP-M500, 300 watts RMS 4 ohm or 500 watts RMS 2 ohm.
The budget for the sub is $90. So far I've found the following options:

This Kicker is by far the cheapest option but Kicker recommends minimum 1 cu. ft. for a sealed box and a friend of mine said that the 150 RMS max makes this sub underpowered compared to the amp.

Rated higher than the Kicker sub, 250 RMS 4 ohm max, seems to match well with the amps 300 RMS 4 ohm rating. Smaller box requirement.

Similar the the above alpine but even smaller recommended box volume. However it is a 4 ohm dual coil so I'm not positive of its application to the amp.

This sub is above budget on Crutchfield but I found it for $70 dollars on another website. Similar to the Rockford but rated 50 watts higher. Once again though Im not positive of the application because it is a dual coil 4 ohm.
Any and all opinions are welcome, suggestions for other subs as well.

I had one of THESE for a while. For the price it's hard to beat, and it would work well with that amp.
Dual 4ohm coils wired in series would show the amp a 2ohm load, so you'd have to find a sub rated for at least 400wRMS to be safe. At your budget that would be tough to find a sub worth buying.
If the box ends up smaller than the recommended volume you can add a bit of poly filler to make it seem larger to the sub (bags of poly available at walmart for a few $).
Make sure the RMS rating of the sub you get is at least 250 for 4ohm load or 400 for 2ohm load.

Thanks for the suggestion, I ended up going with the polk you recommended. Just wondering; do dual coils subs sound different than single or is the only difference the ability to change the resistance of the sub through wiring? is the only benefit of DVC subs that modularity offered by variable resistance?
