I can't tell anyone either. BTL is the only sub that will do that in my truck. Every other sub, including some 12-spoke platforms, WITH softer suspensions wont do it. BTL does it with less than RMS.
I dont know. I wish I did, because I have a lot of money invested in my truck, and wish I could do some stronger numbers. Don't get me wrong ive gotten good numbers out of it, But they are going down hill.
Like I have said before.
This BTL has been put in ~5 different boxes, ran off of 3 different amps, in 3 different installs. Same thing.
Same thing, same volume, same problem.
forgot to mention, if anyone wants to question my install integrity,
Jntar, DJman37, Meglomaniac, Alpineinstaller, BassMekanik, and I think ~MagicMan~ all saw the BTL do this, and Jntar and DJman, were involved with several of the isntalls of it. We can take the BTL out and drop the MAG in on the SAME power SAME amp, and it wont do it.
