Hey guys, I have a question.

I have a pair of Alpine type-s sps600's
these: http://www.crutchfield.com/p_500SPS6...e+type+s&ssi=0

They are mounted high on the rear deck of my car where the OEM location is (97 saturn sc2). These have aimable tweeters and I was wondering which direction would be the optimal direction for a wide soundstage? I have played around with angles but I couldn't hear a difference since I kept moving back and fourth. Now keep in mind that the rear window is right there on an angle /= and that is most definitely reflecting the sound. So do I want them aimed back to the window so it reflects the sound that way or do I want them aimed forward towards the front of the car?

So any ideas?

I would try to get them as close to on-point/on-axis as possible (aim'em at your ears). Aiming tweeters at a concave piece of glass seldom yields optimal results.

To the front it is.

 

My car is quite small inside, and when my system is on it sounds great, so not that it would make a HUGE difference but still, there's a method to my madness

Yep, aim the right tweeter at the driver and the left tweeter at the passenger.

Shouldn't it be the other way around?

wouldn't that mess up the stereo image?

Cross-firing them generally works very well.  Among other things it helps compensate for the fact that the passengers sit on the extreme opposite sides of the car, much nearer one front tweeter than the other.

These are rear tweeters, and it is only cross-firing for a left-hand-drive car ....Devil
