I recently upgraded my speakers to PowerBass 6x9's, tweeters in the pillar, and 6.5's in the rear with block of plates on all the doors. I have also purchased a Kicker Keyloc and Key200.4 to run in Bi-Amp mode, which I have yet to install. I'm trying to figure out a decent subwoofer for behind the sent without doing any mods and do the install at once. I was looking at the below sealed enclosures, but I'm not to sure what would be optimal with a Kicker Key500.1.

1) Proline Single 10" w/ Kicker Comp R wired at 2 ohms for 300 watts (The box with the 12" Passive Radiator)
2) MTI Single 10" w/ Kicker Comp R wired at 2 ohms for 300 watts
3) MTI Single 8" L7T wired at 2 ohms for 300 watts.
4) MTI Dual 8" L7T wired at 1 ohm for 250 watts each.

I specifically want to go behind the seat to keep my floor space. Any help is appreciated and I get that there is probably 100 ways to do this. Im just looking for good sound nothing really to hear me coming 1/2 mile down the road or to rattle bolts loose.

 

Can you do option 2 with it at 1 ohm?

 

I never really thought about it because of the chart below. After you mentioned it I researched a little bit and it is common practice and better to send it clean excessive wattage. I didnt really think of it that way...I was playing the numbers game trying to match stuff up.

 

It will be fine, go for 1 ohm

 

I used this in my sons F-150. It works great as we go motorcycle riding and pile all of our gear right on top of it.
