Glad to see your up again! Awesome stuff coming along there!

i like your style in the mid 1980s a good freind of mine bought a new Toyota pickup and the first thing he did was bring the Truck to one of our local Stereo shops in SouthFlorida and when the Truck was done he and i got a ride to pick it up after the paperwork was done we climbed in the truck to drive it home and we both had something poking at our backs so we jumped out and flipped the seat back foward to see that the Speakers they mounted on the cabs back wall were right where a Steel bar was on the seat back and the installers just bent those bars with a hammer to allow the seat back to go back as far as possible now the stereo did Rock and was very loud but that brand new truck was the most uncomfortable truck to ever ride in as luck would have it he and i worked together and often carpooled we did have to take his truck on certain days because it was set up to carry the tools we needed to do our job he eventually totaled the truck and removed his components to install in his next vehicle that was a van with plenty of room in it for mounting all the equipment years later. i bought a new Ford and wasn’t happy about the Speaker sound so i went to a Circuit City to see if i could get a better set of Speakers a Salesman saw me listening to what they had and asked if he could assist me i told him yeah it says these are the ones that fit inmy truck but they don’t sound much better than the Factory ones in there now Why ? he told me Ford used JBL speakers that arequality but unfortunately on my truck that was a extended Cab Ford engineered it for 4X6 speakers and i was looking for 6X9 sound but i was Adamant about wanting the Truck to not get cut up and still look Factory clean he told me enclosures would be my only option but that wouldn’t work as my small children needed to ride in that area and jump seats so i had to live with the factory sound for years in that truck and my next one i made sure had the 6X9 which meant going to a Chevy 3500 Extended Cab that i paid over 60 K for brand new basically so i could have the sound system i wanted FYI i’m 57 years old and in my time we used to drive American Muscle cars that had a package shelf behind the back seat that allowed us to mount practically anything we wanted and yes the 6X 9s were our choice in the 1980s we used to buy a brand who isn’t around any longer named Cricket that had a Lifetime Warranty so good that even if you pushed a Screwdriver through the cone they would replace them free of charge it was a no fault Warranty and most of my high school freinds used that brand FYI my Buddy that had the Toyota still has the head unit he got with that system which is a Alpine Cassette deck i liked his so much i bought the next model down and installed that in a Jeep i bought and drove daily that i did install Sony boat speakers in the dashboard where the Factory ones were originally those had some Poly cone that you could actually spray with a Garden hose and i used on my Fishing Boats as well

Nice install 👍 we have a 2019 4WD SLT Crew Cab GMC Sierra. We live in Vegas. To bad you guys are not here. Great 👍 video. I just subscribed.

Sucks about Scott, but glad you got to drop another cool vid. Wish you could do a vid on a late model Santa Fe or Sorento. Everyone does vids on the pick ups, especially Fords. This was cool because you took us from the concept thru the application phases making it different than the run of the mill pick up featured vids. 👍👍

how do you find the angle to make the box cuts? for wedge or boxes like this?

DOPE!!!!!!!!!!!!

Do you guys make it with some type of grill to protect subwoofer? Also what is your opinion for best for rock metal and mix of rap ok the 4 8s ot 2 10s or 12a? Can you do 3 10s in one of your boxes? 😊

You are still able to install the seat on front of the amp rack?

I've been wanting to upgrade my rear door speakers and I'm interested in getting your adapters....but I don't know the specs to replace them besides that they are 6.5's. What ohms, mounting depth, recommended wattage, etc...any chance you could point me in the right direction?

Maybe I've just been around JL audio to long and have there logo stuck I'm my head but where the seatbelts buckle into , looks like the JL logo just upside down , wish you had some templates for 98 Toyota 4 runner thanks for the videos from Knoxville TN

The Arc series subs are really nice. It's surprising not too many people are familiar with them.

I wanted this speaker box until I seen the price. Awesome looking product.

This dude has been on RU-vid forever!!!

I miss your vids! Been wondering when the next upload was coming 😉👍🏼

New to the channel, but I've seen a couple of your builds. I was just curious, are the pallets in the "sky" to help with echo?

So I have a just picked up a 2021 GMC sierra 2500 HD AT4 if I bring it do you can you put it all in for me for me and I’ve got the bowl the bowls in the doors the bowls in the back of the subwoofer under the middle counsel should I change my factory radio but I wanted to have all the features that it has right now you know with Apple CarPlay all navigation stuff like that can work out the steering wheel controls

Awesome jobs guys. Do you make a kit for the multipro tailgate?

Glad you’re back, enjoyed it. We just did a 2017 Silverado we called Gentleman Jack with a full Powerbass system with a behind the seat amp rack. With the box we did we had to raise the seat up 2 inches, did you have to raise the seat amd if not you could offer seat riser aluminum spacers.

Awesome tht loos factory

Those custom brackets are solid! But I would have used rivet nuts. One less thing that will vibrate loose.

hello how much does a drawer equal to that cost me for a 2019 chevy silverado

Do you sell the sub enclosures or specs for wood measurements to build my own

Nice build, but I want to hear how it sounds!

Are you running all of the doors/tweets off of the bose amp? How do you get more sound out of the rear door speakers?

Anyone know what wheels are on that truck?

I love your guy's work. I was jut wondering how much it will cost. From the dashboard.doors and subs

Where did you get signal? I tapped into my factory Bose amp for signal on my last 2016 Silverado. I have a 2022 AT4 HD and I was wanting to tap the amp again but not sure how on this one.

How can I get this same enclosure for 21 GMC Sierra. Love the way it fits under the seat.

I have a 2021 gmc At4 and want do the same thing to mine so I guess I would take a vacation to Nashville Tennessee just to copy the sound System in the video lol

I have a 2020 Gmc Sierra and I need to know how to stop my altenator from cycling so that I can get a constant 14 volts for my audio system

Looks clean! But little kids are gonna kick the crap out of those underseat woofers. Also less neons/leds. It’s not ‘98 anymore. They need a PS2 hooked up to that inverter so to keep the passengers happy or the driver during pit stops. I remember they did bring out a Blu Ray player for a car but I don’t think they have a screen that does 1080anything even to this day. Lol

Just found this channel and loved this build I'm getting a 2022 at4 built right now can I order everything from Texas I would love this set up in my new truck

Hey love the channel. If I may ask a question. I have three amps in my car sounds great I have bass speakers midrange speakers and tweeter’s amazing but when I turn the car off it makes a loud thump from the speakers any idea what could it be? Thank you.

I got a 2022 at4 2500. I'm interested in a box for either 2 8s or 1 10. About how much would that cost lol. Can't find shit for my truck

Hy lm Robert how much for a amp rack , have a 2020 silverado

Do u guys make adapters for 8” for a Acura TLX 2015 for the front doors??

I wanna see some goodies for the 14-18 Silverados :)

I want to know how much does it cost for that speaker with the neon lights in it I have a Chevy truck 2021

I have a 99 f150 XLT an four skar svr 8"s I want under the back seat can u guys make a box or know specs for it. That would slap

Is possible to add amp and subs to an electric car? 2022 Kia EV6, it has the meridian sound system with a woofer but it’s weak sauce

Can you laser precut the deadener, too? That would be a cool selling point.

You should include nut zerts.....the DIY guy that doesn't own the $25 tool to install those and needs nut and bolts is 100% the guy that's going to put Phillips tip thru the surround on mid bass trying to hold speaker and drill in screw...lol

Demo demo demo!!!!! 😂 I know it’s coming

Sick work ,question do you do middle console for 2016 GMC Sierra slt 4 door let me know

Just got a 2022 GMC Sierra elevation, would love to have this build with 4 8” sundown subwoofers but I live in Hawaii..do you guys ship to Hawaii???

I need a custom speaker enclosure for a 2021GMC denali can you help

Awesome, can you do something for the tailgate speaker?

Why couldn’t you make the door brackets clip in like the factory? Could have used a key cutter on the CNC to make the slot.

Nice build, but damn you need to find energy. Like watching a documentary about dentistry. Keep up the good work.

Looks bad ass! Ive got a 2020 AT4 2500HD. Whats the full set up like this cost installed? Might be a little too baller status for me but lets see :)

How come no deadner on the block out plates? Not needed?

Would you be open to offering an unfinished flat pack for the enclosure and if so how much?

Nice video, can you please do videos for GMC and Chevrolet?

28:20 doesn’t seem to be a locking nut on the back which it really should be with all the vibrations caused by speakers. For the cost of the install you could afford the extra 5 cents for the locking nuts.

i just bought this truck!! how do the factory speakers sound with all those subs?? can they keep up?

Great video

I have a 2020 silverado I need that set up please

Do you do or have anything for a 2016 ford f150?....

I see you sage

I need that sub box

That build was nice bro where are you located

I have a 2016 Chevy Silverado LT 1500 did you say this box will fix?

Wow awesome setup, how much to build me a box like that with 2) JL Audio 10s

Do you make this for Silverado 2003 extende cab

I was Browsing through your website I noticed nothing for Rams! No Mopar Love?

I just wonder do 4- 8" subs put out some deep boom.. And 10's might fit and i think 3 sundown 10'S WILL bump that old bass boom mc AD lol

How much are your 8” adapter’s they look nice 👍 just like factory

Is there a cover for the sub box? I could see a kid putting his foot through one of them?

Nice Build, But The Subs Needs Speaker Grills

What's that wiring harness thingy called

Does that box fite on the 18 model??

How do u get clients I can't seem to get any and I love doing car audio systems

I would like to make a project on my wife's car Nissan Sentra I would like to put some Memphis everything Memphis speakers & the amplifiers n some 12 tweeters in the front n 3 subwoofer

Love it how much is the cost for doing this job.

It's a cool workshop you got bro but what's up with those wood pallets hanging from the ceiling above the entry way/ garage door? it's looks risky & kind of cray cray, just saying.😎✌

I love your sub enclosures, just wondering if you sell prefab enclosures for the 2013 F150 crewcab.

What did you guys used to bypass the bose?

👍👍❗

What would the box cost on a 2019-2021 truck like this

2020 ram 1500 similar build?

Just wondering how much did all cost for this truck owner

No demo on the sound quality?

How much for the box I need one for a 2021 gmc sierra??

I have a 2001 Dodge Ram 1500 Sport extra cab. I need an under seat sub box like that. Can you help a brother out? 🙏
