show me a 3db increase from doubleing power in your car and i'll be very surprised. thsoe are decent numbers but the 50 isn't as easy as your thinking its gonna be. but good luck.

Want to put some money on it? I was there for the install and I know it has a 50 in it.

i didn't say it couldn't do a 50. I said good luck on a 3.x db increase jsut by simply doubleing the power and stuffing pillows in the trunk.......

His car was also sealed up vs. outlaw. Defiantly seen cars go up more then 3db by opening a door.

i watched my sunfire lose 4 db by opening the door when the mic was in the kick. so can't count on that. trunk cars are weird like that. it may good for him I jsut said i'd be surprised.

Did you open the right door? If you open the door on the same side as the mic, you are almost certain to lose.

Bottom line - 150 in a trunk is not only possible, it isn't really that difficult at all. I'm not running an SPL rig, not even close really with the 30hz tune, and I could very likely hit a 150 by strapping a 2nd Sundown to make about 3500 watts.

You need to clarify yourself. 150 where? And it isn't that difficult? Right. . . I see you depending on a lot of "rule of thumbs" to predict your score. Doubling your power does not lead to a 3db increase in real life. More like 1-2. Also, how do you know that sealing your trunk will have you gain? Even if you do try to stuff with pillows, you still have many cracks and open areas that you'll most likely miss. Some cars are louder sealed off, some are louder with box pushed all the way back.

I already did clarify myself if you read the rest of the posts in the thread.

Forget I mentioned a 150 though. That isn't my goal, and I don't really care. I'll leave the arguing to someone who actually wants to hit a 150 in a trunk. Anyway I would think if jntar, who has heard it in person, says it could hit a 150, I don't know why so many people get upset about a claim like that. Sorry if we offended anyone //content.invisioncic.com/y282845/emoticons/rolleyes.gif.c1fef805e9d1464d377451cd5bc18bfb.gif

By the way, the pillows would be a temporary seal. I'm going to semi-permanently seal the trunk at some point when I figure out how. I've talked to different Camry owners, and am fairly well aware of the pros and cons of forward, rear, upwards, and sealed from the trunk firing.

Oh yeah, the 146 was with gains at about 30%. I have driven around with them at around 40% for a day and no clipping up to 29/35. So I haven't even explored the upper limits of gain on the Sundown yet. For all I know I could burp it at 60% gains and 30/35 without clipping. But right now I'm not really crazy enough to try.
