cant belive it

wired my sub down to two ohms and at 8 was already flexing the whole car. now the windows if they are halfway down or so they move both ways about a inch. can windows crack from this? I know its impossible to blow out windsheilds and all but if you have a window partially down without all the pressure available, can it snap or crack?

It is possible to blow out a winshield.... it's on this site somewhere, and on youtube.

Vids of OP or the winshield shattering?

not entirely true. he has a D class amp. say he has 2 dual 4 ohm voice coil woofers. lets also say his amp is 1000 watts at 1 ohm. if he runs the woofer in a series to parellel to get the amp to see 4 ohms the amp would put out about 500 watts than he changes the woofer to a parellel configuration to get the amp to see 1 ohm he would get 1000 watts on the same woofers and would result in about hearing difference around 3 dbs.

I know one guy on here with an astro van like pushed his windows out ward somehow.

I think you didnt quite get what he was saying though.

I have one sub. its a dual 4. was running it at 8 ohms, now running it at 2 ohms. my amp puts out 1000 at 1 and 2, 850 at 4, and id say 700 at 8. my doors are flexing alot and that is why the windows are to. comprehende?

You can't crack the window glass, it's tempered, but it will shatter in to a million pieces.

Lowering Ohms lowers the resistance allowing the amplifier produce more watts.

More watts = MOAR DBZZZZ

What happens is the window gets rattled off it's track, then the pressure pushes the windows outward, and there goes your window.

But to OP: it is possible for you to crack / break your window. I don't think I've heard of a side window going out though. Most of the time it's the front windshield. The pressure on such a large area tends to push it out and eventually breaks down the material and it cracks.

Not fun... (or legal)

Like my window did last week! There was glass everywhere. I'm still finding it in my car. :\
