Bronco audio upgrade build: Hertz woofers, Audison tweeters, Rainbow midrange, AudioControl amp, JL

[Les Korcala]

After only 250 miles this Bronco needs audio upgrade
this is going to be my only second upgrade after I did few years back in my Xterra
Components used for this project :

front stage 3way

Hertz Mille Legend MLK 1650 6.5 woofers
Rainbow Germanium Gl M3 midrange
Audison Voce AV 1.1 Tweeters

3 Way powered by AudioControl LC-6.1200 6 Ch amp
Subwoofer
JL Audio single 10” W3v3-4
powered by JL JX 500/1D mono amp

for now I like to create front stage only with delete rear speaker.
I noticed after removing cargo area panels , sides, floor and more there are lots of flimsy rattling plastics as well as the Ford use of new hybrid thin steel in floor section of the Bronco makes for passible vibration and noise transfer from under muffler area.
first what I did is checked Db noise levels with my iPhone app.
did this before I start sound proofing cargo / doors area

I did two tests :
car running and parked with all electronics off , audio, heater etc.. 46 dB for an average 3 minutes interval
2nd one was driving on the highway at 65 m/hr in 5 minutes it scored 48 dB I was suspecting it will be way higher with highway noise ! Anyway, I will compare these numbers later with full sound proofing.
I do not believe roof section of the Bronco ( inside ) can not be improve in any way ! When you run you hands along the thin carpet section you can heard different rubbing and shifting sounds , when I drive off road I can hear these exact noises coming from inside the roof cabin area
Pone person put 300$ in to applying sound proofing stuff after striping of the thin black carpet and reinstalling later only to find out it improved about 5% overall noise from the inside roof walls , waisted projects on his part but he wanted to proof it.
few photos from first steps of sound proofing inside Bronco
I will try post each steps towards audio installation.

I'm subscribed to this build. Love the gear. Do you plan on installing the mid and tweeter in the factory dash location or pillars?

 

[Les Korcala]

Hello ,
Yes the plan is to use 1” tweeter and 3” mid in same spot
I need to fabricate plastic plate to accommodate both of them
Would love to build pods in the pillar like I did in my xterra but here with airbags and removable roof not passible
Also , 2 goid sized amps hope to mount in the floor cargos storage area too bad that tun is curved I need extra 1” to fit both
Passible cut in to and make it working or totally construct new insert

do you know how the bass blockers work I have no idea ? Is something to do with stock head unit never build one with it , do you need them ?
Do you know anything about harness , can you build one yourself from amp to hu
I know they ate kinda $$

Bass blockers are just capacitors one connects in line with the speaker wiring in front of the speakers. Any blocker you buy is going to have leads on either side of the caps to easily wire them up.

I think I found the answer here
The reason why Ford has bass blockers on the dash speakers from the factory is because the dash speakers are fed off of the same line that feeds the kick panel speakers
I was asking since i never had to use them in other cars

Day 2 working on Door treatment using cheap but proven stuff i used in past on my Nissan Xterra
Doors can be tricky to disassemble ( panels ) I have some good images and will post it tomorrow O wanted to be consistent and applied treatment to inside door skin as well
Plastic covers could not be coveted they have weird molding to it but as long as i did the inside parts it should be great ! I checked with mu hand knickles and sound is dead and low and quick and that is what i want.

Yes .... exactly

I installed a 4 channel amp for the front stage and wired each channel to a speaker, eliminating the need for bass blockers .... my front stage is phenomenal.

Why not use 2 way Hertz tweeters if you're going with Hertz 6.5's? it will be an easy drop in.

Also, Mabett came out with new pods for the back that can house 6.5's instead of factory pods that just fit 4's.

What product are you using for deadening? Do you think there’s room for amps on the driver’s side rear, behind the panel?

I truly enjoy watching people & there builds. ALL of you with the talent to do things like that is a joy to watch.

I would be the bull in the china shop, it wouldn't be pretty

Sound deadening looks like roof/window flashing. It’s the cheapest trick in the book and does the same thing as all the others. Only downfall is depending on the kind you the inside of your vehicle might smell like asphalt for a while, but eventually goes away

How much weight did all of that add?
