Thanks Guys, This Sub is Loud and it goes Low even with this box: 3.5cf @33Hz and 67.5 Sq". I'll try to build another one 5cf @32Hz later. I'm just fixing some details in my new box which is 3.3cf @33Hz and 72 sq" the difference will be that the new one is firing up and the port to the back, lets see wich one sounds better with the 15's That I have.
I'll try to install the 4hp this weekend or next week, I can't wait to heard it.
My car is an Eclipse 00 and the port is 5" close to the back and yeah! my car hates me lol. Car is full of Second skin. Sounds good but there's some rattling, It's not easy to eliminate it with this big toys, they are doing some damage to the car.
I'll be trying to get more then 8 cf for the next box, 6 after displacement will be cool.
Thanks Chad, sure just lmk when you're gonna come down and we can do something, tomorrow I'll be testing the new box and maybe throw it a destroyer to see how it sounds.
Definitly BTLs FTW... DD too . First time that I switch the subs I was like wow! Because I really feel it louder and lower than the DD, personally I couldn't stand it in the car more than a 1 minute at that volume, it made my ears hurt. Actually the sub stared to smelll lol. That night my head hurt like hell, I don't know what it was but I think that it was the loud sound that made it hurt.
I'm gonna be honest, I like the FI better because is low & loud to the ear. I have my reasons to think that the DD is loud to the Mic. Another thing is that I need to play more with the sub, the gains, etc. cause I haven't had time.
Now, there's other factors that I know can make a difference, thast's why I don't want to say this one is better than the other. For instance the load: DD was .8 Ohm Dcr and the Btl is 1.4 Dcr. I found a different one when I was testing the DD, the Volts dropped at 11.5 at times. Because I was only using one battery in the trunk and that battery was tested @ 1280 CCA, right now with the Btl I have 2 Nsb90 that were tested @ 1920 CCA each, now the volts never go below 12.2. and there's some more little things like that, that make a difference. Anyways I might be reconing my DD to try it again.
