Ok i bought a New Polk Audio DB1240DVC sub

Thiele/Small Parameters
Recommended Enclosure Sealed/Ported/Bandpass
Resonant Frequency 28.3 Hz
Qms 11.7
Qes .4
Qts .4
Vas 2.87 cubic ft/81.4 L

And i wonder which amp would be best to use. Im building my own box, I got rid of my kickers cause they required to much air space. This sub only needs 1.5 cubic foot box so i can get it in the trunk. These are the amps im lookin at.

a class D mono-sub amp is more efficient for this application. If you get one that is 2 ohm-mono stable you will be able to get max power out of your amp. I don't pay attention to power ratings on speakers myself, just match the impedence and give it as much clean power as you can. The budget will probably help decide which brand you can go with and the brand can make all the difference.

I have not posted anywhere else lol. I dont want to over power the sub though and blow it. So i was wondering will that MTX 300w @ 2 Ohm be good since its a DVC which would make it 360 w RMS at 2 ohms max on this sub.
Does anyone know if Polk Audio are good. I just wanted something different and away from Kicker and MTX subs. Cause everyone has one.

What type of box are you putting the sub in?
If in ported you should spend the extra money on the amp to get something higher quality with a subsonic filter. Woofers in ported enclosures do not like playing notes below the tuning frequency at high volumes...
You cannot beat this for the money...
