These are nice little entry level amps! I had the JD 400/4 in my setup before getting more power hungry speakers and upgrading to the JL audio HD 600/4 and XD700/5v2. I’m very impressed with all JL amps I’ve used so far

I'm glad you do all these helpful videos Mark. I'm no dummy when it comes to car audio, but every little tip and trick is extremely useful and helps a lot! Thank you sir for doing this!

Great video! Love JL Audio so I’m super happy to see you reviewing their stuff. I love the clip light. I wish my HD900/5 had it!

I installed the JD500/1 in my car a few days ago. I LOVE THAT THING! I am still working on cleaning up my install with the help of this channel. This is the first time I install a full sound system (stereo, speakers, amp and sub). I am now working on doing the big 3 and upgrade my alternator.

I have the 500 watt version of this amp and it sounded noticeably better than the 500 watts kenwood amp I was replacing. Really made me want to invest in their 4 channel amp on this line too.

What model of Kenwood you have?? I have the JL Audio JX 1000 series for my w7 and kenwood excelon series. I think excelon have better sound quality then JX but for more power JL. I was thinking upgrading for this amp maybe sound quality improve.

@mrb9106 I had a kenwood KAC-500 for my sub I believe. It wasn’t their excelon series. My speaker amp is a kac-6407. It doesn’t sound bad but I like to match.

I have a full set of the previous generation JX amps. I started off with the 250/1 & had it for years until it was time for an upgrade & of course I stuck with the JL Audio JX range & I’m now running 2 x 1000/1 & 2 x 360/2. After seeing this amp I want to upgrade to the new generation JD amps but I can’t justify the cost at the mo!😔 I’m a JL lifer these days & when time comes to replace I will stick with them for sure. So many new sick features over the JX & the JX aren’t crap either!🤣 Mark your review videos are great as you cover all the good shit! I just wish you was in the UK!😜👍🏻

I watched JL's overview video on this series the day it launched, this is definitely a lot of amp.. it's entry level, but it's a few giant steps above entry level quality.

I love JL Audio.. I just started to install a small system in my Honda Civic because of the Roni Rona. I installed one 10 inch sub in the JL audio H.O. pre fab enclosure and small amplifier XD600/V2. I really like your video's!

They are decent price. I will be definitely looking into them since i am doing a full JL audio build in my Tundra.

Thanks for this video. Will definitely check them out. Seems like a really good choice for entry level amps.

I watched this video & went to Crutchfield to order the 500/1 for my 2 15w0v3 subs. Really wanted my old school planet audio to push em but you can hear they are craving better quality amplification. Thanks for such a great in depth video!!!

Love your videos. Great for a beginner or someone who wants a refresher.

2:13 ... good information on power output, the majority will not be running an upgraded electrical system(alternator/batteries/etc), for the past 20 years, autos have a charging system monitor that feeds information to the PCM typically connected to a sensor attached to the negative side of the battery cable, my 2005 gmc sierra 1500 has this. After the vehicle is first started, the alternator output will be at a typical +14.4v, as the battery is monitored and slowly charged back up, the charging system will go down to +12.6v so it doesnt get overcharged and be kept topped off, at least during the day with all running lights off. At night time with all the running lights on, the alternator output will usually stay at a constant +14.4v due to the load demand and other accessories you have running at the time.

I had an entry-level jl audio subs amp and it was so nice!!! Only thing missing is a super sonic filter!!!

Love your videos! Thank you! Keep them up. If you're ever in Orlando, social distanced drinks are on me!

I have the JD1000/1. Last night while I was setting my gains following their instructions. I hooked up my multimeter so I could see the voltage that it was putting out. I knew at 44.7 that equals to 1000W. The clipping light didn't come on yet after reaching 44.7 so I kept slowly increasing the sensitivity dial until the light illuminated. If I recall correctly it definitely hit 53 maybe even 54 before the light illuminated. Thats about 1400-1500W!

This amp is way better than entry level tf 😂 JL is top notch

I like how amp said 8 gauge and you feed it 4 , more power the better. .. love ur videos and ur passion for ur craft! €_€

I used to have the previous gen of the 250rms watts and those tiny amps have more balls than those that claim to be 1200 watts!! It provides enough power for a single 10” w3 which that amp is made for or w7’s now but they can easily power 2-10” no problem. I highly recommend.

Thank you for helping all of us

Great review! You're always super through when explaining this stuff to newbs like me! Thanks for sharing

I’m a sucker for clip lights right on the amp! Definitely a feature packed budget friendly amp.

I'm looking forward to the next video. I want the all-in-one box. ;)

I was biased against JL audio for years and always thought there was better stuff at the same price point. I have since changed my mind a bit. There RD line up is hard to beat at the price point. I currently run the XD lineup and it is amazing.

I have the older Slash series 5 channel JLAUDIO amp. I am keeping that. Great amp. I have the older series JLAUDIO component speakers and the older JLAUDIO 8 inch ported sub. Keeping all that too.

For those who complain about JL Audio prices, do you have any idea how convenient and sometimes essential all of these rare features are? There's so much built into when these entry level amps. I run all JL Audio. JL Audio HD750/1 to JL 10W7 JL HD600/4 to JL C5-650 doors & RBH 4” Beryllium on dash JL 300/4 to Vifa tweeters on dash and bass shaker in seat JL Twk88 DSP to run 3 way active front. No rears JL Audio is subjectively the Best, and objectively easily within the top 5 car audio manufacturers.

Its nice to watch a video so useful to newbies like me a big fan here in the philippines always watching your video wish i had one of those sub aits like my dream to have a set up in my mini van like my toyota avanza 2015 e but dont have the budget , because of some priorities id love to have it and put in in my ride . Hoping to learn on your next video big fan here in PH

If I remember correctly, the NEXTd use next-gen FETs that are highly current efficient, but are surface mount (I don't see any power or output FETs with the bottoms cover removed). If one of those go bad, the repair tech had better be good and qualified for SMD repair. Thankfully JL's repair services for amps is actually very very reasonably priced.

I recently installed the JD 400/4 in my Camaro and am very pleased with the performance. These amps deliver a pretty powerful punch at a very reasonable price point.

Thanks for the info great job 👍

So when using a ported sub box with this amp is there a need to for a subsonic filter? I was under the impression that if one is not used it can damage your sub in ported applications. When would you need an amp that does have these options?

As a recommendation for the quick remove power connection look into Powercon connectors, They are used in Professional live audio and lighting applications, they are rated for at least 3600W and you would be able to use all 3 of the power terminals +/-/Rem in one connector.

Hey. Do I need a line driver if I'm only upgrading my 4 stock speakers and including an amp? I have an after market head unit.

I just installed the jd/400 amp with some component speakers and rear coaxial speakers how do i figure out what filter frequency to set it on ??? i hope you see these

is there any substitution for the bass knob? or is the rbc-1 the only one i can use for it?

so i just bought this amp ALSO my KnuKonceptz wire kit came with a 80A AGU Fuse . do i need a 30A AGU Fuse ? i don't want to damage THE AMP

This might sound dumb, but I’m trying to figure out what size fuse I need for multiple amps. I watched you video on how to calculate them. I have the jd400 hooked up to 4 kicker 75watt door speakers. What would you say is the peak output of the 400 setup that way? Thanks for any info.

I'd love to see how to set input sensitivity and find clipping using an old school oscilloscope. I have one but cant figure out how to set it up and use it for car audio.

Does this amp require a high-low converter on an OEM system?

I have a question i have a line output converter so I can get rca.now if I put this amp in offset or signel and I close the door or boot my sub goes crazy like its getting full power but the head unit and car is off.ive had another amp that did this when current goes to the amp but the headunit takes time to turn on.only amp what didn't do this was a hifonics amp what had soft turn on and it helped with the mad craziness. Any ideas ?

I have the jd500/1 4 channel , if I want to set up what hz test track would I use ?

Why would I be able to turn the clipping all the way up without the light coming on? It’s the 500 watt version with two 250watt subs. To tune it to the right sound I turn the bass boost 90% up. I can turn it all the way up if I wanted. The other setting is at 80 like yours. Thanks for any input you can give.

Quick question how you tune a dual woofer ported box in cabinet no divider

Hello im trying to power 4 prv 10chuchero what amp would be good for that?

Hi sure it could also see distortion on the input being its the same thing, the dd1 can test through the amp also

This line or JX models are just awesome!! I have tested 250, 500 and 1000w and they rock!!!!

I have a DD1 but as an installer at a shop it's always nice to have a clipping light so I ain't gotta pull that out

I am completely new to this whole car audio stuff. But do i need one amp for my 4 speakers and then another for the subwoofer? and how do they connect? So about 500€ just for amp´s then 200€ for speakers and whatever the subwoofer is what i have to expect as entry or am i getting something wrong?

Hello. I have a single JL audio 10” wov3 300watt that I want to connect, will this JD250/1 amp work well with it? Thanks In advance

For the remote wire you can tap into a fuse in your fuse box. I wrapped my remote wire around a 12v plug in fuse that’s always on so if my car is on, the amp is on

Hey mark, Would you happen to know how to wire a center speaker? For example, my car has two tweeters on the front dash as well as one in the center as well as the woofer in each front door.

@msmith954

4 жыл бұрын

You won't need an LC2i or similar unless you are using a signal from a powerful factory amplifier. If you were using one, you would set the input voltage switch on "low"

whats the efficiency like on this?

Any way you could do a video for the people who are just starting out on what sub distortion actually sounds like? A lot of newbies don't know that it's harder to hear when it starts when the sub is in the trunk. Heck, there are a lot that don't even know what distortion sounds like period. They usually roll up to the gas station, windows down, blasting a heavily clipped sub signal and actually think they're bumping nice and hard. I feel embarrassed for them.

Question: would it be possible to use the clipping light on the amp to find the maximum undestorted radio output volume? Ie. turn the gain on the amp all the way down, play the 50Hz test tone and increase the volume on the radio until the clipping light illuminates? This should, in theory, be possible as the amp would see clipped signal already

@msmith954

Not really. The amp's LED is connected to a circuit that monitors output clipping, not whether the signal coming in is clipped.

What’s a better buy a JD400/4 or a Sfb-200.4D

Would a jd500/1 and a jd400/4 be to much for my car’s electrical system? I’m not gonna be running them at max power.

1. Mark would this be a good combination with a Kicker CWD 82? 2. Is it 1 Ohm stable? 3. I don't see a fuse on the amp itself, does it have any other way of protection?

@michaeltempsch5282

4 жыл бұрын

Not Mark, but: Given that they don't list a 1 Ohm power rating it's unlikely to be stable at 1 Ohm. That limits your chosen sub (dual 2 Ohm) to be hooked up in series, ie a 4 Ohm load. That'd give you 150W from this amp. They list 50 to 200 for the dub, so it should be OK, if not absolutely optimal. As to fuse/protection - looking at the manual it looks like they rely on upstream fusing, recommending a 30A fuse on the power wire. So if you run multiple amps, I'd use a fused distribution block, or put a separate inline fuse close to the amp, after an unfused distro block.

is it enough with JL Audio W3 6W3v3-4 this speaker??

Do you make custom in closures for customers I’m looking for a small rear center with a 6.5 sub for my Cl55 coupe I have the rear center console I could send you for measurements

That's precisely what the 4 channel version is designed to do. This can be paired with any brand and for running the highs.
