need sub recommendation

[sdwrx 10+ year member]

My box is made from 1/2" MDF, with a 3/4" baffle and has approximately .9 cu ft of airspace internally. It can fit any 10" amp that has a depth of less than 7". I've attached a pix and amp specs below. My amp is an older MTX thunder pro. Any suggestions on subs under $120. thx

AMP Specs:

37.5x2 @ 4 Ohm

75x2 @ 2 Ohm

150x1 Bridged @ 4 ohm

280 Dynamic power bridged @ 4 ohm

RMS rating are at 12.5 dc input.

well if you willing to spend about $10-$20 more a P310D2 would be a great sub i think since they can be run sealed or ported box i had some until i upgraded to the P312D2's

sorry for the newb question... but what's the difference between 150x1 Bridged @ 4 ohm and 280 Dynamic power bridged @ 4 ohm?? I've never heard of "dynamic power". Should I be looking for a sub that is rated at 150 or 280 rms? thanks guys

Too me dynamic power always meant max which to me meant not gonna happen...However I could be totally off. But if your amp is 150wrms@ 4 ohms @ 12.5V then in your car (which will probably be feeding it 13.4-13.8v) your amp should make a little more..

Yes, it seems tht dynamic power is just what the amp might hit for a second or two. It cannot maintain that continuously.
