What gets crisp notes for speakers?
 

just driving in peoples cars the last couple days, (all stock stereos), but they sounded better than mine :/

the speakers had nice crisp notes, clean and hit pretty hard, what creates that for door speakers? my door speakers sound terrible compared!

the 2 cars were a '10 bmw 328i and a 2011 mini clubman if that matters or they use a certain brand

just curious, i have been learning about subs the past few weeks and i guess its time to expand a bit more and try to learn all the aspects, i would rather have a nice SQ install thats clean than anything else and im prepearing for a new car with a full decent system (hopefully)

proper eq, more amp power, better speaker placement, maybe a dedicated high frequency transducer. could be a bunch of things.. these ones come to mind tho right of the hopp

Newer cars put a lot of effort into reducing NVH as well (noise/vibration & harshness). Some sound damping in your car would go a long way to letting any installed equipment work at it's best. A lower noise floor and less vibration/ringiong of metal lets speakers sound more as they were intnded, and they do not have to compete with wind or road noise.

Is it the stock system in your car? Do you have separate tweeters or co-axial speakers? Are the speakers amplified? For crisp sound you need speakers with separate tweeters, the paper cones alone won't give you that. Most oem, non premium sound systems don't include proper tweeters, bass speakers or amplification.

i have a stock system, but it is the "upgrade" audio package pontiac listed for the bonneville.

i have seperate tweeters at the tops of my doors before thw window and speakers at the bottom, SQ to me is that "crispness" and quick hitting notes a system has, no notes that hit and linger or fade out (unless there supposed to be that way),

i know it sounds stupid to compare to MY car with a stock system, but i am just wondering so i can incorporate whatever it is into my new car,

Check to see if you have actual tweeters in the sail panels (triangular area by the doors) or just cone tweeters...a lot of upgraded systems used and still use crappy cone tweeters instead of proper dome style tweets. Even my 04 300m with the infinity premium system came with cone tweeters in the sail panels. You may just need a set of add on tweeters for crisp sound. Many oem systems were just lacking upper and lower frequency performance...case in point, my 94 mach 460 system in the stang just needed tweeters and a sub to sound pretty good..midrange and midbass were pretty good.

i have cone tweeters in the sail panel, but even in the mini, it has NO tweeters but the awesome crisp sound is coming all through the speakers, it dosent have much bass but its so clean

what channel amp would i need if i wanted to put my back 2, 2 door, and 2 or 4 tweeters on it?

A 4 channel will do 4 speakers and you can just add tweeters with passive caps (small capacitors to block low frequencies) in parallel (speaker wire + to + and - to -) with the rear and door speakers. Like these:

I would say this is a big part of it. A new bmw probably has some solid doors with a bit of dampening that helps the sound alot. Dampening the doors will help your sound alot, especially mid bass.
