Want more midbass?

I am posting this because I saw in another thread which I can't find now, someone trying different 6" door speakers to get better midbass. If you want to get good midbass from your 07-14, put 8" midbass or woofers in the doors. I did this in my 08 Sierra with the use of a speaker rings/adaptor that I designed. I have attached a PDF with a scan of a speaker ring/adaptor. You can print it, and cut it out and use as a template to make your own out of 3/4" MDF.

This along with a good amount of sound deadening, and foam between the speaker and the door panel, will get you good midbass in one of these vehicles.

What HZ frequency range are you trying to increase through the use of a larger speaker?

hard to get mid-base in these vehicles unless you go with very high end speakers and amps

I have edited my original post because the way it was worded was a little unclear. I am providing a template for others to use to put 8's in the doors.

Ok. Makes sense.

I was wondering, as a good quality 6.5" speaker with an external amplifier will give you solid (and loud, if you want it) frequency response down to 80HZ. At that point, a good quality subwoofer with an external amplifier will give you solid frequency response from 80HZ and below. At that point, there should not be any mid-base gaps in the overall sound.

What you are saying makes sense in theory, but in my experience due to the high pass crossover point of 80hz for the door mids, they are still playing sound all the way down to 20hz due to the roll-off that the crossover provides (usually 12 db/octave). A quality 8" can produce those lower frequencies louder without distortion when compared to a 6.5".
For those not using a sub, going with 8's in the doors will have an even more noticeable affect because the door speakers are being relied upon to produce mid bass and sub frequencies.

Yes, I agree that if you are not using a subwoofer in your system, it may make sense to try to accommodate larger door speakers, if you want to get more prominent lower frequencies.

However, if you are using an integrated tweeter/midrange and subwoofer audio system, a 12db/octave Butterworth high pass crossover for the midrange speaker is a pretty piss poor crossover, allowing a fair amount of sub 80HZ sound to leak into the midrange speaker, as you mentioned. You want to be using a 24db/octave Linkwitz-Riley high pass crossover for quality sound filtering. Likewise, you want to use a 24db/octave infrasonic low pass filter in the subwoofer part of the system.

More mid-BASS is not that hard, we actually have a good platform to start with. I have always loved 8s up front, best way I have seen to blend bass and midbass to create up front bass.

being able to upgrade the bose subwoofer in the center console to a 10" JL sub-woofer will give you the "up front" bass that will make for a nice accurate front sound stage. (i'm using a high end 3 way set up, 6.5" mid bass in door, 3" and tweeter in the A pillar) My .02

I've had active 3 way setups in my Camaro and old Burb. Can't touch it IMO once you get it tuned right. I probably won't be doing it on the '12, just a 10" console sub and upgraded woofers running off a PPI 5ch to start with pulling signal via an Audiocontrol LCQ1. Hopefully I don't get the bug to go crazy again...that shit snowballs. LOL Where did you get your A pilar pods...asking for a friend.
