Help with box dimensions


Rgjr702

Recommended Posts

Okay guys so I have 2 12" pioneer champion series 309d4

I had them with a hifonics 1200 Brutus.

I recently picked up a Rockford fosgate power t1000.1bd .

I had the subs in a weak cheap vented box. It hit the highs real nice,

And idk wat it was tuned to but the amp made it bottom out when hitting low bass.

And there is no subsonic filter on the amp. The specs say its 28hz.

Correct me if I'm completely wrong,

I put them in a sealed box and I turned the gain down a little but and it stopped bottoming out.

But it's not hitting the highs as nice as it was but lows are really good now.

Now. What I need to know is what dimensions do I need to make a ported box that will respond good with these subs and this amp

Any help is very appreciated.

Oh and I want full spl. Thanks

The biggest I can fit in a Monte Carlo 2000 trunk, space is no problem I need no trunk.

Lol

I was thinking (lxwxh)

It has a switch, I think the brutus was enough heat for those subs besides those have a tuneable subsonic filter. If you have the full dimensions of the prefab uncluding the dimensions for the port, post them, likely a lower tuning will help with the bottoming out but not with the loudness.
