Why do people put 2 diferent size subs on the same car?

[kmu]

hi there, I've seen several installs with diferent size woofers but of the same brand and sometimes diferent brands... Like 2 10inch woofers and 1 15inch...or 2 12's and 1 15....

What's it for?

THX again...

Right now i have a 15 and it literally takes up my hole trunk cause the box is jumbo. and i am thinking of also getting a 8 to go with it or a Bazooka tube. won't the 8 inch make it have better sq and not bass?

What's it for? I have NO idea. If you have a 15" driver and wish to have better sound quality, adding 8" drivers are NOT the way to go, sorry. Having 12's and 10's for a nice mix of SPL and SQ does NOT work, it just makes it sound worse. As far as mismatching subwoofers *sigh* I have no idea why people do the things they do. If you want better sound quality than your 15" sub can produce, buy a better subwoofer. If you want to keep the sound quality of your 10" subs but want more boom, then buy 12's instead (the difference in SQ between a 10 and 12 of the same driver is barely audible for the most part, and you get better low frequency extension). People are weird.

I am a firm believer in mixing but I would use like a single 12 for deep bass and put 8s up front crossed over in a bandpass where it cuts off at or around the same freq as the 12 for more solid midbass and again where I would cut off the midrange components..lots of extra time and tweaking involved though...for most it isnt worth it.

I have an 8" up front in my car... it blends quite well with the 15"s in the wall... took a good bit of tweeking though...

I was assuming having an 8" in back with the 12's or 15's when I was saying "no no". I'm going to have 8" upfront as well.
