Monoblock Class D Subwoofer Amplifier, 500 W x 1 @ 2 Ω / 250 W x 1 @ 4 Ω - 14.4V
Designed to produce a whopping 500 watts into 2 ohms (14.4V, 1% THD), the JD500/1 amplifier is a great solution for powering subwoofers in a cost-conscious system. Our proprietary NexD™ switching technology delivers large amounts of real-world power output with excellent efficiency and ultra-low distortion.
The JD500/1’s controls are located on the input panel. while the power and speaker connections can be found along the opposite end of its extruded aluminum chassis. Signal processing features include a 12 dB / octave low-pass filter, with continuously variable frequency selection from 50-500 Hz, and a variable bass boost EQ. Dual-range, differential-balanced inputs are also on-hand, capable of accepting line-level and speaker-level signals. Automatic turn-on capability (via signal sensing or DC-offset sensing) is standard, along with a set of preamp outputs so you can easily pass signals to another amplifier.
The JD500/1 is also equipped with an onboard LED-clipping indicator ring, surrounding the input sensitivity control. This useful feature lets you set your amplifier’s input sensitivity, quickly and accurately, without special equipment. With the addition of an RBC-1 remote level control (sold separately), you can control the subwoofer level from the driver’s seat.

Glen and the guys did an amazing job installing a towbar and wiring kit on my vehicle. Well priced and they turned it around in a few hours on pretty short notice. Highly recommend.
Big shout out to the boys at TJM Northern Beaches. A great job for my suspension upgrade. Knowledgeable, greate communication, workmanship and efficiency. Very happy with the result.
Great team effort from Sales, Installation, and aftersales in looking after my GVM upgrade on my LC 300 GRS. Many thanks 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!
Great service and workmanship. Jason and his team looked after me very well. answered questions and emails promptly.I would recommend these guys!
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. 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!
Phoned in the morning… with the roof top tent in stock… dropped vehicle off at lunch, and had it back that afternoon. Need I say more!? Thanks gents!
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.
Thanks Glen and your team for an excellent first class service. Very price competitive as well.
The lads helped me out last minute to install my rooftop tent. They had all the necessary tools & equipment and were super friendly and helpful. Thanks guys!!
Got my TJM Outback bull bar, Rock slides & 2” lift with them in Brookvale.
Glen and the team are first class.
