Did you visit their website and see what is the smallest recommended enclosure that they say is optimal for the subwoofer, that is where I would of started

ok

In case you couldn't find it.

Enclosures:


BTL 12 – Ported box we recommend using 1.75-2.5 cubic feet @ 30-35Hz (I personally think that a 32hz tuning is optimal, and has the most output and is still the most musical daily driving). Use 12-16 square inches of vent area per cubic foot of volume.



BTL 15 – Ported box we recommend using 3-5 cubic feet @ 30-35Hz. Again use 12-16 square inches of vent area per cubic foot of volume.



BTL 18 – Ported box we recommend using 5-8 cubic feet @ 30-35Hz tuning, you can tune a little higher if you wish but we recommend keeping it close to 32hz for a daily driver. Again the same 12-16 square inches of area applies per cubic foot of volume.

Impalas have huge trunks. Y go for the smallest?

It most likely will be choked in that trunk. Look into the 15 perhaps. Are you putting the amps, batts, etc in the trunk as well? You will have to account for more room for those items as well.

x2 on the 15" sub. that way you dont have the chance of choking it. be sure to give the port air space to move around into the cabin (assuming you are firing towards the rear of the trunk)

what sub/port placement do you want?

I have mine in 4 cube temporarily and tuned to 40hz. It's pretty loud and sounds OK. Looking to rebuild as I think it can be more efficient and sound a bit better in a larger box. If you can't get the 5 ft net, go for a 15.

I think 18s are more suited for SUV's

hes new to car audio?? seriously he probably doesnt have a slight clue on how much money he is going to be throwing into this especially just for the electrical..

I had a Chevy Lumina and the Impala's, and monte's all have the same style trunk i was able to fit 3.5 cuft without chocking my 15" if iwas him i'd either look into two twelves or 1 15"
