on the TL i hit 148.3 with 2 crappy treo 12"s and 1000rms with stock electrical which is like 60amp alternator. when the season starts ill be putting in a h.o. alt with 3 gel cells and 6k rms off 4 12", should get fairly loud.

 

that's a good start. you should be at the 150 mark in no time.

 

i hope so, lol.

 

What kind of amp or amps are you using. Change your subs and amp and you'll be there. I bet you're losing all kinds of air from the two side back windows. If memory serves me correct those windos are not sealed shut but open up.
