Hey guys, can I use a sub for sealed application on a tline? I have an old school MTX Blackgold sub and was wondering if I could put it in a tline... I'm gonna power it with an old school HiFonics Thor VIII 400 watt amp, will this set up work or will it be a waste of time... :)

Not to be a dick but your sig is fucking loooooooong.

I suggest a 35hz tuning.

Make sure you have the room for it, though.

ok thanks I fixed my sig.... and I built the t-line for the 8.... WOW !!!!!!!!!! tuned it to 39Hz, and it peaks at 48 in the Envoy. It did a 134.9 on the dash 132.4 @ the head rest... Not to bad right, with 100 watts. Let me know what you guys think, oh and till i can find the time, i mean untill i'm not to lazy to build a t-line for the mojo, I slapped 8 10s back in.

I would recommend two serperate lines.

If you can't fit them.

Do a Line with both of them side by side.

Tunning to 33hz would be optimal.

Measure from middle of the surround on one side to the middle on the other, then, times that by two and you have your area.
