well it would work but the sub would be sleeping... and in trunk it tkes good power to make good bass....
the risk you run when under powering is that it'll be to quiet then you'll crank the gain and clip the amp... and blow the amp.... also with that amp you have to run at 12ohm... so youd be getting 250watts or something.....

Look for a JBL GTO 1201.1, it can be had for around that price if you look around. That amp will do 1200ish at 2 ohm and 800 at 4 ohm, so somewhere around 1000rms at 3 ohm. Providing you keep the signal clean that sub will handle all kinds of power.

the impedance of a speaker has little or nothing to do with how much power it can handle. It's just a measurement of resistance. That resistance is what the amplifier will "see" and will determine how much power the amplifier produces.
The JBL GTi is a crazy sub. It's good in pretty much every way. You do not need much power to get decent bass, yet it can take a ton of it. I would ignore the 800watt RMS rating. They can take more power then you can afford to give them.
There are lots of amps out there that can do what you want in your price range. JBL of course make amps that will work for you, as do Alpine and many others. Some amps (like the JBL and Alpine) do not change their power rating with impedance between 2 and 4 ohm.
Your sub is a dual 6ohm. But each coil will only be 6 ohms when they are static. The impedance will change as the frequency changes.
You can run one amp on each coil with no problems. The just need to be the same amp and they should be set up properly. If you go with this route, I would suggest getting amps that are electronically stackable. This will give you more power and lots of flexibility.
