The one thing that sets you guys apart from the rest , it’s not an act when your recording your episodes ,just continue being humble and bad ass car audio installers ..

Thanks!! We appreciate it! Just posted a new video, check it out!

If I had a dollar every time a customer ask me if I "turned the volumes up on amp" or " did set the power on amp all the way up"....I'd be a millionaire...I don't even try to explain gains anymore...lol.... I set and put tamper sticker over gain hole on amp.

Hell yes. 2020 has been so crappy. Been in lockdown since pretty much March. Now all these videos this week has made me smile for the first time in ages. Could 2020 be improving🚴 Thanks my friends. Keep at it

I got the Utopia M 3 way setup like in the video but with 2 Helix C Four amps and Helix DSP Ultra. With the Flax components for rear fill. Wish you had a video or picture of the sound treatment after it's all put in. I want my megacab fully sound treated. My driver door rattles bad just with the factory system

You can squeeze DC level 3 12s under those seats with a seat spacer. I have a Jekyll and Hyde type of listening preference.

[@SoundsGoodStereo]

It is possible, but need a custom shop that really understands enclosure design to pull it off.. I would recommend building the enclosure first, measure the airspace and then choose the best subwoofers for the airspace.

Planning the stereo build on my 2021 ram 2500. Selling some parts from the chevy and buying the amp ap4-ch41 then its a matter of planning out the layout for the amps and building a sub box. Excited to run active for the first time, but nervous as hell lol

[@crazyscott71]

yall should look into the fox acoustic/ fox box. I have 2 of them a two 10s ported and a single 12 ported really nice boxes

[@SoundsGoodStereo]

We have used them, but we are picky on the performance for our clients. So when we can build the enclosure that best fits the subwoofers requirements, we can achieve better results. But for most people the Fox box will work just fine

[@sjaxon29]

Is it possible to get the box done for a couple 12’s? I’ve got a 15’ crew cab Ram.

We would need the truck here to do it.. Contact our retail side and they can schedule you in. Soundsgoodstereotn.com

Around how much air space is that box? I got a massive audio gtx 104 10” I want to build a ported box and want at minimum .92 cu ft to 1.25 cu ft

[@jwbboy]

Would like to know this as well.

[@SoundsGoodStereo]

I actually don’t know exactly, but I assume 1.8 cuft based on previous ones we have done.

[@bugsysiegals]

I’ve never done fiberglass but have a wood working shop in the basement and am willing to tackle making my own enclosure after watching you guys knock this out, thanks for showing us all how it’s done, and you guys are really cool funny guys! That said, how much air space do you have there or if you raised the seats and built it taller? I’m considering 2x JL 10w3’s or 10w6’s but am not sure either will work with speaker height, ideal cubic air space for each, how to tune the box, etc. FWIW - I’ve a 17’ Ram Sport Quad Cab.

[@joedelpopolo4087]

Nice box I have a Question for you about the build.. when building the box and laying down the fiberglass resin how are you fixing the fiberglass to the wood trim perimeter to construct the initial volume part of the box before adding the top that will have the sub opening? I've watched multiple videos and it looks like everyone is applying the resin up the side and barely going on the top side of the perimeter. I can't see how the resin wouldn't break free once bass is added. Is the screws that stick out that gives the resin a bite to the wood or is the bond just that strong that it just stays once the top is screwed and glued? I would think you would want to add layers over the top around the sides but that would cause fitment issues right. Please explain this step for me if you don't mind.. thank you

[@SoundsGoodStereo]

The MDF wood is very porous, so the resin absorbs into the wood and creates a bond. Kinda like wood glue at the joints, the glue once dry is stronger than the screws/staples.

[@joedelpopolo4087]

@@SoundsGoodStereo thank you that is what I was guessing from exactly what you mentioned it works how glue would. Thank you this will help me with my build for my town and country. Appreciate it again.

[@mattroadfeldt9012]

Good work! What do you use for mold release?

[@calvinhobbs89]

Pva is the best but any type of wax release mold wax but the finish side of the tape not adhesive side also helps or will work to release glass

[@Watchingyou-daily]

KFC-XP6903C would have been a decent alternative or maybe KFC-XP6902C depending on the speaker size in that dash.

[@SoundsGoodStereo]

For a basic upgrade, yes.. But bigger is not always better, so the Focal Flax components were the perfect choice.

[@philipduncn1495]

I know I'm a little late to the video but did you guys ever decide to start building boxes and shipping them I have two 10-inch DB Drive g2's that I want to put in a 2012 Ram 1500 been considering building my own most prefab boxes we don't have quite enough mounting depth I need at least 7 inches mounting depth for those subwoofers

[@SoundsGoodStereo]

No, it’s not something we will offer. Very focused on the current enclosure designs and select other vehicles. Maybe one day we will circle back around to this truck

[@LC8FTW]

How did you figure out the volume of the molded enclosure? By pouring gallon jugs of water in it until it's full?

[@SoundsGoodStereo]

Great question! So we use a test tool, same as this video (start at 4:53) and this tells us the real air volume of the enclosure. kzbin.info/www/bejne/oZSXcqmcpNKXf7M

[@LC8FTW]

@@SoundsGoodStereo IMSG. Interesting. I'll have to dig into the spec of that device and see if they published its margin for error.

Do you guys happen to have a better step by step build on that ported box? I’ve seen a few vids on making a similar box but none have shown a ported one and it looked pretty fast on this video.

How did you guys determine the port for the fiberglass enclosure? And how do you determine the volume approximately with all the different surfaces? Water? Styrofoam peanuts 🥜?

Thoroughly enjoyed watching this build. Looking for solid tips and tricks on doing a similar box on my '17 1500 Ram. Would it be possible to give an approximate on the tuning of the box? If not that. The approximate size of the cutout on the port? Any info would be greatly appreciated. Job well done, fellas.

port size on the box would be completely different considering what subs were used

Better sound with 6 1/2 over 6x9?

In some cases yes. If its a better 6.5-inch, but most higher-end speakers do not come in a 6x9

You still would have clearance issues. You have to notch the lip of the factory midbass hole.

[@eddiemenchaca7224]

I have the focal flax and have to cut the Scosche adapters, but would prefer adapters that don’t require cutting. If you have a link to the adapters, that would be awesome! I assume whatever works for this Ram would work for my 2019 Ram 1500

Here is the process at 5:05 in this video kzbin.info/www/bejne/oZSXcqmcpNKXf7M

[@michaelflowers6048]

@@SoundsGoodStereo I guess what I should have said is. How did you calculate the dimensions of the box to build to reach the adequate airspace? For example say you have two 12s to fit in this box that require 1.02 cubic foot of airspace each, how would you know how big to build the box with this odd of a shape? The subwoofer box that is in the Ram 3500

[@SoundsGoodStereo]

Not really a easy way to do it. We always build the enclosure first, then measure the airspace and then find the best subwoofers to fit that airspace. We never go into a project like this assuming the subwoofer size first, unless we have already measured in a previous vehicle. Your best option is to build it as big as possible and then shrink it down if you need to. Another option is to use sand and fill it up, then measure.
