ok thanks waggy I appreciate the feedback everyone. I am not running the angle face box right now, I am running my box before that. Its a flat face subs tight together, drivers side slot port. @3.6 cubes. Hey rob I got 4" sewer pipe, could I get away with that instead of 6"?? single tube per box??

 

give it a try.
maybe you could get some 4' aero's, and use the sewer pipe to tune it.
a termlab would come in handy.. an audiocontrol pressure sensor will work as a comparison tool, and might get you louder(it only reads the loudest individual frequency, TL uses an average of 3 frequencies)
testing, testing, and more testing is the only way to get loud.

 

ok thnx rob. I wish I had a mic, it would make my life a whole lot easier. My goal is to hit a 150 in my neon, but I guess we will see

 

if running an external port, I suggest 3.0 cuft, other than that I agree...

 

if you get a mic , do some testing to find the natural resonance of the car and you may be able to use it to your advantage
