I was wondering if I can run my friend's Fi Q in my box that is 4.5 cu ft tuned 32?

It has BP option, and I would be running about 1000 watts to it.

Would the sub be fine as long as I am responsible?

Well, how big is it?

Lol duh. Sorry bout that.

It's a 15" Fi Q w/ BP power.

I would wait for on the the Fi guys to read it. I think it would be fine, but I would wait for more input.

Alright I'll wait.

Thanks.

Ported box we recommend using 2.8-4 cubic feet @ 28-33Hz. Again use 12-16 square inches of vent area per cubic foot of volume.

The response curve will likely suffer. It will be a little 'boomier' and not as accurate. Your mechanical power handling will decrease as well so make sure you watch your gain and subsonic filters. It will work if you want something to listen to though..

Aight this will only be to break in his sub a lil for a week.

Thanks dude!

I would leave it in that box, that's perfect, I ran mine, 15" Q w/bp D2 on a fosgate p1000-1bd in 4.8cuft tuned to 28hz, absolutely slammed, you just have to be careful with clipping, I had upgraded alty and and a yellow-top under the hood and in the trunk with big 3 done, so I could get a true 1kw out of the amp, and be clean power. You will probably be a little louder than mine was, but I never heard a system get low on gorilla zoe until I built that box!! LOL

oh yeh, I had no issues, ran it for ~6 months, then sold to a friend, still pounding just fine for him ~4 cubes tuned to 28hz.
