Recommended Posts

The truck definitely likes he lows. It's doing way better than I expected.

Good idea of testing with an imsg. I am curious as to what the final tuning was

Change in air temp/air density? Something in the vehicle move the least bit?

Spitballing here.

It was hotter out Saturday than it was Tuesday night. Probably 20° difference at least.

I'm by no means an expert, but physics and math I do know. Hotter temps = less air density. How that acoustically effects your peak frequency I can't say, but 20 degrees is plenty for an obvious change.

Im happy with the score. Just wanna know why I didnt get a higher number at a higher peak. Putting an IMSG on it this week hopefully. My current best guess is that based on rise starting at 2ohm, the amp and the cabin like 30hz.

R you limited in power for your class or something? Add more power and that bish will get loud.

We will put out through the IM-SG this weekend if you'd like :)

It's a good number and it feels great inside the truck. I think it will really wake up when the second amp goes in and both are running at 1 ohm. I still think they may be begging for more power ;)

Im not the one you want to try to troll. Just a fyi for you.

Nice. Remember, seal it up, and dont move or touch anything. It is VERY VERY sensitve. Read the directions, and you see exactly what that bitch is doing.

I think you may just be surprised. ;)
