does anyone have any advice to move the sound out more on the hood? create depth? is this only achievable by placement and aiming? i searched a little, and maybe missed something. thanks.

defro13 good post... I also prefer on axis for depth, detail, and accuracy as it performs best that way, though I think off axis can work but that will depend on the specific radiation pattern of the tweeter (and the amount of reflective surfaces as well as the non symmetry of your sound field have to be taken into account as well). you can also do EQ to imply depth but it wont be as believable as what is recorded on the CD (assuming the CD has depth)

friggin hard question as there isn't any magic **** to turn to increase depth

Totally agree with the above two posts.

I am an on axis guy as well, level matching is critical as well as the

obvious "install"

minimize the pld's

crossover settings (frequency and slope) also affect height and depth quite a bit.
a poorly crossed over midbass in a door can destroy depth

thanks for the responses,unfortunatly i won't be moving any drivers this year,although i wanted to try something different. happens.i did take my time aiming them to the position i felt they sounded the best,and still maintain a symetrical apperance.x/o's are set via hu, high,mid,low. so they should be the same right and left.

could you expand on the eq settings? an idea of where you might cut or boost. and i totally agree all recordings are not equal.

mabey i should try multi quote
i think height is good, i think width is good,although i don't have a real referance in a car. everthing is on the dash,on one track i listen to,there is a symbal crash that seems to be coming from the rearview.

dont know if i agree with the on axis theory dave... as many of the worlds best cars have had off axis speaker installs... from the buick grand national, harry kimuras legend, gary biggs buick, dan pohalmas civic.. as a matter of fact very few national winning cars have had on axis speakers..... now that being said every car mentioned has tremendous amounts of technology behind them to get them to sound the way they do..... does the average joe have the time, resourses, knowledge, or money to accomplish what these people have done............................... problably not so its just easier to get them on axis... if nothing eles it is a visual cue for the judge... but in my experienc you get "beaming" biasness... almost every time even with the best t/a its still prevelent... also staging will be limited to where the speakers are. so again unless you have acess to nasa, or the jbl labratory you are going to have a less than optimal stage... depth might be there but not both!! we are near field listners for the most part.. and without some funky processing and install magic. ie rebuilding dash, roof, floor. it probably wont change... whew!! so to get the best of apillar builds do what you said dave all the way. but please dont think that its the only place for optimal sound in your cars speakers, its just the flavor of the yr on speaker placement.... hell next yr it will be dead centre of the roof above the rear view mirror... as long as a respectable name wins at iasca with it....lol!!!

I think it can be done either way but the goal is to retrieve the depth in the recording, the area most tweeters are most accurate is on axis so it follows the best location would be on axis. Off axis is what I am currently using BTW. Still the off axis can sound better as the automobile itself alters the sound so profoundly.

Let there be no mistake the USACi score sheet has little to do with SQ and a lot to do with install, the IASCA score sheet is much better but the car that sounds best is only implied by winning. Many of the champs have or have had on axis installs (some of the same cars I might ad as they change year to year) it really depends on the build what you can get away with.
