I agree im purchasing One this week. I had actually just called JL about this amp and days later a video comes out. Man i was Excited to see this video. Not to mention this thing has a dampening factor greater than 1100. Which is amazing even the HD series dampening factor is this high. I am not sure if there is another amp on the market with a Dampening factor this high. Thumbs up to JL and the supporters.
@@odeball22 most definitely a good high quality option. I was getting 51 volts clean no clipping according to the oscope on my jl. Puts it at around 2600 watts.
I am part owner of a shop, been in the industry for 17 years. I want to carry jl so damn badly. I’m a sony es, alpine asc, kenwood excelon, msc, audio control, hertz/audison and missing jl so badly. but another shop in my county has jl already and they won’t open me up.

I love the RD line.! I have had the RD 900 Which was amazing I am now running the RD 400 on my mids n highs which are The JL C250components And the JL C2 50 coaxial I cannot wait to get my Rd 1500 for my subs. I have been hearing nothing but great things about this amp
I got the RD1500 to replace a RF punch 1000... both great amps, but this D class amp runs so much cooler than the A/B Rockford Fosgate. The RD 1500 is having a grand time powering a single 2 ohm 15 inch P3 sub in a sealed enclosure. I honestly didn't think the sub would survive for long, but it's been taking everything I've thrown at it, and asking for more. :) Love the RD series of amps. Good performance and looks super clean.
I have this installed in my pickup powering 2 10tw3’s at 4ohms and boy oh boy does this thing sound tight and clean. Have a video up, would load more when I am back home.
@@Chris-hc9vb I have them wired to a final 4ohms, if you have the space for the 12’s then go for it. The 12tw3’s have a lower fs so you will get more lows. The RD 1500/1 is doing a pretty good job for me plus it’s a versatile amp that could allow for future upgrades if u need the full 1500 rms
Hwy Mark, love the videos. Phoenix Gold was doing this same sort of thing back in the early to mid -2000's with their Xenon line of amps. They produced the same amount of power no matter the impedance. 8 Ohm (bridged), 4, 2, or 1 Ohm.
Dang, Mark....I was planning on getting the 8/800 vxi but now I'm going to seriously consider 2 of the 4/400 with AC608...damn u and your videos 😆...quality vid once again!
Was on the fence about getting a JL rd 900/5 and a fosgate 5 ch. for my new build this summer, now I’m sure I’m going to take the plunge and buy the JL. Their amps are so well made and totally worth the $. Thanks Mark, your videos have helped me design my boxes and system so much better than I used to back in the day.
Have had my RD 900/5 for about 6 months now and it produces a little under 600 watts for the sub channel. Zero distortion or alternator whine coming from C1 door speakers, a clean and crisp sound, love it!!
@@Erik122198 I’ve had the Jl Rd900/5 for 3 years. 2 months ago I played it for 5 hours straight full volume and it’s still doing good. It sounds good and clear.
It's officially called a C-Clamp Retainer that holds the screws on the cover plate. They are used on throttle and shift linkages in cars and it's an excellent idea for JL to use in this application.
Hi CAF I came accross your channel trying to learn how to upgrade my stock audio and love the knowledge you share. Could you offer advice on how to become a pro like yourself? Did you attend a trade school? What course(s) did you take? How long has it taken you to aquire all the awesome knowledge you share? Any books you recommend? I hope it's not too much info to ask of you, just thought maybe others might have these same questions. Thanks again for all you share with us. ☮️
Do you have much experience with the xd line? Are they an improvement over the rd? Why is the xd 1000 more pricey than the rd 1500 for quite a bit less power?
Why does JL Audio make their XD amplifier have a worse S/N ration than some of their lower products? I also don’t get why the HD750 has no new tech to it.
New subscriber, have watched quite a number of your vids into the wee hours of the night.. Great, detailed explanations and your craftsmanship👀 is LEGIT!!! continue the great work👍👍👍
I didn't hear you tell them when picking it an amplifier it can be important to also check to see in what orientation is the amp is suitable to be mounted! Not all orientations are acceptable for all amps due to the heat sinks and other circuitry inside the amp. Some need to be orientated in certain orientations in order to give off the heat the produce without melting down! Otherwise good job. I do appreciate your channel.
Mark, I have the RD900/5 powering 4 door speakers, and the RD1000/1 pushing 2 12 inch W3s. (The sub channel on the 5 channel amp is not being used) Pioneer double din head unit. At very low volumes, when my RPMs move slightly, I will hear a popping noise out of the front speakers. If I turn the volume up past 6-7 or so, I never hear the popping noise. Have you ever experienced this? Both amps are grounded to a distribution block, and then to the seat belt bolt under the rear seat. (2004 Toyota 4Runner.) 4 gauge power ran on one side of the vehicle, and the RCAs and speaker wire on the opposite side. All 4 of the speakers sound amazing on this setup, and the subs hit very hard. There is also no hiss or whine what so ever, just the popping noise at low volumes. Thanks in advance.
I have the JL Audio XD100/1v3 and soon I’ll be buying the JL Audio 12” W7 Subwoofer. I also have a JL Audio 600/1v3 running 2 X 10” W3v3 subwoofers, pricey Stuff but well built class D amplifiers and subwoofer.
I just got this today. I followed your steps but the clipping light wont come on. What does that mean? I ended up leaving iit in the position you have anyway in your video. I will admit, this amps blows my old JX1000 out of the water.
Hey man I have a 2016 silverado with the factory bose system . I love the way they sound I just would like more bass and don't wanna change the factory head unit because some of my settings go through it for the truck. What can I do.
Ps glad they ditched the famous plugs that came with the hd-series that were horrific to get in or out I feel like putting a little bit of petroleum jelly on mine lol
How did u set the ohms meaning 1 or 2 on the switch. I just ordered the hd750 because it looked smaller. I have a 12w7ae in a g37 sedan with a jl jx1000 right now
Question! I have the RD 900/5 and was wondering if I could get a mono and another 10 inch sub to pair with it? Would like to keep everything JL Audio, just don’t know if I have to get rid of my RD 900/5 and get a 4 channel and a mono. Would like more bass, but I do not want to sacrifice mids & highs. Any pointer on how I could achieve what I’m looking for?
This amp is intense! I have a question that don't know if it's ever been addressed. If you have a DSP, I have the Dayton DSP-408, and want to bypass the amps crossover, and there is no off switch, do you turn it all the way up or down utilize the DSP's more powerful features?
Hey brother, recently found your channel and it’s great! I’m an old bass head 20 years out of the game! My last system was a single JL 10w7 and a JL slash 1000/1v1. Soon I’m having 2 JL 10w7s installed. The shop recommended the RD1500/1 to drive them. I’m curious of your thoughts on that vs say an HD1200/1? And since you’ve been in the game a long time, how would you compare them to the old 1000/1v1 slashes from the early 2000’s?

have this amp but Im thinking I want to Up grade to the HD1200 x1 because it would give me a cleaner install along with my HD 600 x4 but am i truly losing 300 Watts
Wonder how this compares to the 1200/ 1V3 (slash series) I have two of them on 2 w7 13’s. I wouldn’t know if this amp would with with the 13’s since they’re at 1.5ohm
I have a important question about running this same amp on a tw3d-4 was told this was too much power to one sub and could blow my sub? Would I be Okay? or should i buy a smallee amp for my sub?
Is this their more affordable range because it seems like a step backwards from their HD series by a big lot lol, don't mind the black and blue light it's just not as compact or high quality looking, missing Tiffany style rca etc too 🤔
I did a car audio upgrade, mids/ highs, sub, custom box, amp for mid/highs, amp for subs high/low converter and epicenter .everything was done the right way, no corners cut. But with that said I’ve been getting white noise coming from the speakers regardless if volume is up or off, it doesn’t get louder with volume tho. I’ve checked everything I can think of maybe I’m missing something. Any suggestions what I can check next? Or have you seen anything like this?
Just a personal experience for me, but if the vehicle you have has an active noise canceling system, they tend to interfere with aftermarket audio. Just sends a constant signal that comes through as white noise. Have to either disable or unplug the module to eliminate it. I experienced it in my current vehicle. Hope you find whats causing it.
I have a quick question. Just need some clarification on it. If a person was using just 1 subwoofer on a mono amp...let's say 1200 watts at 2 ohms. Works great. But wants to change it up by replacing that sub with 4 others. Would the subwoofers need to add up to 1200 watts of power handling combined like 300 watts per sub X 4?
According to JL, they advise you to get as close as possible to the subs rated rms. Now to answer ur question, no it depends on ur budget. If you can afford 4 300rms subs, then get them but make sure to buy subs with dual 4ohm voice coils so when wired in series/parallel they give you a final 2ohms as is required by ur amp. Benefits of the 4 subs vs the 1, more cones area i.e. more air being moved therefore bigger bass
I have to wire my RCAs behind my deck in a twisting "8" pattern ( to ground them). If I do not do that, I get a lot of hissing noise. By doing that, I have "a little" hissing noise. Is this my deck that's bad? My RCA connectors on the head unit? Or the RCA cables? Thanks
Get better cables for sure. Cables make a huge difference. But to answer ur question it could be all of it. Most likely it’s the cables tho if u have a good head unit connected correctly
With quality amplifiers like JL Audio no. Some lesser amps you will notice noise and loss of output with heavy bass on the speakers, but not on a quality amplifier. Nice to have the simplified wiring and system design.
Mark, I need your help. What determines what input voltage high/ low is selected? I have an aftermarket stereo DDX9907XR with 5volt preamp output. Does that make it a high voltage output? I have this amp, and the voltage output is set to high by the installer. I don’t want to damage my amps or subs, and I want to make sure the right selection has been made.

That amplifier would be happy with 5V inputs. My older amp from Blaupunkt had max low level input 4V so 5V could damage preamplifier section. It's always best idea to read manual. EDIT: English isn't my native language so i didn't see that you wrote that you have amplifier from the video, in manual for RD1500/1 says "Switchable from 200 mV - 2 V RMS (Low) to 800 mV - 8 V RMS (High)" so yeah, it should stay on High.
Sold separately which is the intelligent thing to do. I rarely use a bass remote with a bass amplifier anymore because I'll use a DSP controller instead for that amp. Why pay for something to be included when I'm not going to use it?
@@CarAudioFabrication why pay something what should be included.. 90% of car audio guys i know uses bass knob and dont wanna use dsp at all..and for me..cause of newborn i would love to have bass knob to completly lower the bass when kids are around..

EDIT: English isn't my native language so i didn't see that you wrote that you have amplifier from the video, in manual for RD1500/1 says "Switchable from 200 mV - 2 V RMS (Low) to 800 mV - 8 V RMS (High)" so yeah, it should stay on High.
@@setecastronomy_hc I have the JL Audio RD1500/1 and head unit Kenwood DDX9907XR
So its just like RF T1500-1BDCP
Can this handle 3 tw5-13.5"? Any1
For sure they’ll be perfect I had that same system
No bass remote
Sold separately which is the intelligent thing to do. I rarely use a bass remote with a bass amplifier anymore because I'll use a DSP controller instead for that amp. Why pay for something to be included when I'm not going to use it?
@@CarAudioFabrication why pay something what should be included.. 90% of car audio guys i know uses bass knob and dont wanna use dsp at all..and for me..cause of newborn i would love to have bass knob to completly lower the bass when kids are around..
It's sooo... Small
First 💀
Boom!
