Enhances the sound quality of any automotive loudspeaker installation by creating an Acoustic Barrier behind and around the speakers.
INSTALLATION INSTRUCTIONS:
The purpose of this kit is to isolate the back-wave of each speaker from the front wave of the speaker, The sound from the back of a speaker is the exact opposite to the sound from the front If the front and rear sounds meet cancellation will take place and sound quality will decline noticeably.
- Mark and drill the speaker mounting holes. NOTE: Make sure you do not use the speaker as a template while you are drilling. Metal filings from the drill will be attracted to the speaker magnets and cause problems as they work their way inside the speaker. Remove all drill swarf and filings with a vacuum cleaner or moist kitchen towel These metal particles will eventually rust inside the door or get into the speakers.
- With a pencil or felt pen mark a small line radiating away from each of the drilled holes. The purpose will be evident when you go to tighten the speaker with the lnstalPro seals in place, it will make it easier to locate the holes.
- Clean down the outer door skin behind the speaker with methylated spirits or wax and grease remover. Pass the 20cm x 20cm ‘egg-crate’ pad through the speaker hole, peel off the backing paper and secure it to the outer door skin directly behind the loudspeaker. If you want a superb job of soundproofing we recommend lining the outer and inner door skins with Focal BAM, a sound-absorbing butyl rubber sheeting. This will do three things: absorb sound, stop panel resonance and create a barrier to sound escaping through assorted small gaps in the inner door skin. The egg-crate pad will absorb a large proportion of the speaker back-wave, the area directly behind the speaker is where the greatest effect can be had. If you already have BAM or similar lining your doors, this pad will adhere to it.
- Choose the correct seal ring for the speaker and stick it to the door skin. Screw the speaker in place, compressing the seal ring. That will make a perfect seal so that sound does not escape around the speaker frame, a common problem because car doors are not always perfectly flat surfaces.
- Adhere the 25mm x 200mm thick foam ring around the speaker, When you restore the plastic door trim this will direct the sound through the grille in the door trim and stop sound from spilling sideways into the cavity between the speaker cone and the door trim.

Highly recommend them – no need to look further. Well done team!
For all 4x4 advice, products and service, look no further than TJM Northern Beaches in Brookvale. Jason has built a fantastic team of professionals who have both in-depth technical knowledge and experience and demonstrate some of the best customer service skills I’ve seen. They beat their competitors in this area hands down. Jason was fantastic with helping me design and specify my Y62 Patrol build earlier this year and was very honest about what they could do / supply and things that I would be better sourcing from other suppliers. Throughout the build, he provided solutions, not problems particularly regarding a pre rego GVM upgrade. He was great in communicating progress and working with Nissan to ensure all the work was completed prior to registration. A big shout out also to Andy and Ed in the workshop who were very patient and helpful in providing me with an operational handover once it was complete. They have also provided great after sales service. I’ll definitely be going back to TJM Brookvale for all my 4x4 needs and highly recommend them – no need to look further. Well done team!

Cameron Newling
The workmanship as usual was first class and I can't recommend them highly enough.
The team just completed a heap of 12v work on my new car after doing work on my previous one. The workmanship as usual was first class and I can't recommend them highly enough. Given my Ineos is a brand new car to market they took the time and care to ensure it was completed professionally and exactly to my requirements.

The best 4WD shop in Sydney, cannot recommend more
The best 4WD shop in Sydney, cannot recommend more. Jason and Des are absolutely legend. They are very helpful and professional, Giving me the best options and keep everything on track. The boys from the workshop also provide high quality workmanship, and easy communication. They supply large range of high quality brands like Jmacx, RVSS, Enerdrive etc, your true one stop shop. I should build with them from the start, it would be much easier!

The guys at TJM Brookvale are absolute legends.
Jase, Glen and Des were a massive help after losing my car in the floods.
My 2022 D’max had a bullbar, winch and lift kit fitted and it looks and feels amazing! The guys at TJM Brookvale made every effort to get the work on my car done the second my car was off the boat and at the dealership and turned it around in a very short time, as they knew it was hurting me having no car, not to mention did it all at a very reasonable price. I can’t overstate how good these guys are. I will definitely be a repeat customer! Grateful to these blokes.
Mark Abela
