SUPER STEALTHY SUBWOOFER UPGRADE for your Range Rover L322 [Audio Upgrade Part 2] 

Another big improvement to the L322's audio system with this subtle, stealthy, yet powerful upgrade! Anyone else planning some audio goodness?

I like how you used WinISD and looked at the T&S parameters. One of the biggest mistakes some people make is to buy a pair of beefy speakers, put them in an enclosure, then wonder why the sound is really awful and resonant. Making sure to match the enclosure size and type to speakers is so important, as it's all one system that has to work together. Great vid!

This is a great idea. I’d remove the carpet from that cover, cut holes to match the speakers and cover with acoustic carpet. That will let the speakers breathe

This was FANTASTIC!!

Ooo nice bit of Ghost there Sam! Great content aswell as ever, very clever use of OEM parts with the enclosure.

Great video. Kind of OEM plus using the older sub box. I love an upgrade which looks factory and you’ve definitely achieved that. Keep the videos coming - super interesting and helpful!

It's a good idea to wear gloves when adding the sound deadening as the aluminium is very sharp as I found out when I used some in a previous vehicle.

Love that Channel! Thanks Bro!

Your response curve looks very similar to the one in my 2004 Lincoln Navigator. The bump you see around 50 hz is the vehicles natural peak. You'll notice massive reductions in output around 60 and 70 hz and then your front door speakers start to pick up around 80 hz and up. Your biggest issue is that a sealed box is not going to have strong output under 40 hz and you're also not going to get strong output over 55 hz due to the vehicle size. This creates a very narrow and peaky response curve for the subwoofer. Basically you get one note bass. To get a real Improvement you're going to want to switch over to a ported enclosure that is tuned quite low. If you were to install a single 10 inch sub in a ported enclosure tuned to 30 HZ you would notice a much smoother bass response curve. Alternatively, if you're not looking for massive output and want to keep things very stealthy, you might consider removing one of the 6.5 subs and sealing it's opening. The single 6.5 will be in an oversized enclosure (oversized for sealed, but just right for ported) and you can add either an internal or external port. Something like a 1.5" tube. Also, make sure to hook up the remote bass knob so you can control it from up front and don't be afraid to raise the level up. 👍

I been waiting so long for this video since your last audio video on l322! Finally a solution to the audio system on these things. Thank you bro!

Sam why not just cut a hole into the carpet and let the original in? Have you tested the sound with the original sub in place without the carpet? I am thinking to cut a hole and cover it with some decent speaker cover…

Like what you’ve done here Sam, good thinking using the old L322 box! Seems almost too good to be true that the standard power cable can be re-used. I guess it’s enough for the micro amp that you applied here.

I see you still have the “Widow Maker” scissor jack in the boot 😮😂☠️☠️☠️

Great video, Sam. Very helpful as i have my new subs on order! Did you manage to figure out what wiring plug is required for the sub amp plug female side?

Yes

Hi Sam, I also did a similar upgrade. Yours is much better thought out than mine though I must say. When it rains all music sounds awful as my wipers make a clunking sound upon changing directions. Do you also have this issue? If yes, do you think there is a solution here? Seems odd a luxury car was released with that clunking sound on its wipers! Maybe its just mine. Keep up the great vids!

Thank you so much for this video, I also did replace the old subs in my 03 L322,what a difference it made. Also have a 2012 L322 and want to do this upgrade, do you have a more specific instructions on connections to new Amp? Any links to Amp and speakers? Great job ,thank you so much for all your videos.

I'm now doing your install, did you manage to find the female plug part number please?

Nice upgrade. Do you know the reference of the front passenger subwoofer? Thx

On the sub box from the 02-04's are they the same for both sides or should I look for a left and right? Great stuff!

Ghost ❤

I have the HD system in my 2012 Westminster which I am quite pleased with. That is apart from the bass that does vibrate a bit when you turn it up. I am thinking of applying the deadening stuff to the original woofer cabinet and the parts of the car around it. Do you think that would make a decent difference? Very good video as always, thank you.

Hi Sam, have the sub control functions in the main screen menu (audio tone settings) remained active?

I'm just wondering if the dual sub speakers should work in opposite direction (phase/ antiphase) because the box actually dosent have any ventilation. It could be checked with just switching +/- of one of the subs speakers.

did that green connector plug directly into the original amp? thanks man , ive got a 2006 HSE im working on.

Just the one subwoofer in the rear correct? (not on both sides) Also, could you post the info for the amp? Thanks!!

How much was that box of deadening material? Where did you get it from? 😃

use this bluetoooth upgrade instead

What year is your L322? My issue is my car was built with a telephone kit in the front and I’m unsure if it is adaptable to a modern smart phone? Keith in Harrogate

Ps my car is a late 2007 model
