ok so i just got off the phone with the tech guys at jl audio. we were on the phone for a little over an hour. they said that they do not recomend the TW5 for a ported box. so there goes that idea. n i know that sealed enclosures sound better with the less vibration. so would putting sound deadner do any thing to the sound? has any one done this?

 

Sealed sounds better with less vibration? More like less leakage.

 

Yes I did it in my center console build, I like the way it sounds and several other guys on DIYMA recommend doing it as well. Anything that will help cut down vibrations and back waves is good in my book.

 

ok is there anything else i can do? it will be a under rear seat box. as far as tuning does any one recomend any thing special etc..

 

If you can afford one, an O-scope.

 

what is that??

That yellow thing, they around 350 bucks though.

 

Yes, its nice because it will help change the Resonant Frequency of the box. But the box will be too small for there to end up being a standing back wave in the box.

 

so what kind should i use though??

 

i was told by a buddy of mine that is in to high end stereos that the blackhole 5 was the best thing for me to use but n e other ideas???
