I just bought this amp, its beautiful, waiting on door speakers, and 1 sub, then i have to pick up a box. I cant wait to install everything! Gonna run skar dds dual 2 ohms.
I bought this amp for 169 around Thanksgiving after my kicker cxa800.1 let go of life. That kicker was a tank. This JP8 sounds better than that kicker. It does take some juice to run. I currently have it in an f150 with 130 amp alternator, big 3, and 112 ah of agm. It still drops my voltage from 14.3 to 13 even on a heavy bass note. I am in a group on Facebook with the guy who repairs the D4S amps. He says that they are safe down to 12.5 volts. They designed them to be lower voltage friendly. With enough electrical behind them they can do around 1500 watts. Best 169 bucks I have ever spent.
I replaced a audiocontrol 1500.1 sub amp with the JP8 in sierra Denali with a 2-12” Jl audio stealth box. It pounds but no where near the level of the audio control. For 200 bucks it can’t be beat
Great review! I totally dig this amp, mainly because of the stuff you mentioned....looks, features and value. And it doesn't require an upgraded electrical system unless you are running it below 1 ohm (it's stable down to 0.5 ohms).
Great review! i've been running a JP8 for about 2 months, powering 2 10" Kicker Comp R's @ 1ohm total, upgraded 200 amp alternator and i love this amp. The fan on mine runs constant when amp is on, but not a problem.
@@DIYAudioGuy Same here, barely even gets warm after 30 min. of running hard, especially with the fan coming on when i first turn it on.. constant cooling.
I live in SC and I have got the thing up to 150 degrees on the bass knob and still hasn’t shut off on me. It sits in the trunk and this is me going full tilt right before clipping for 30 minutes straight. Not to mention this is when it was 95 degrees outside. This amp is an absolute monster for sure.
I bought this, and matching 4channel, as I LOVE the blue, and throw back look. My ONLY complaint is the inputs are on opposite ends, vs. all on same end. As far as the bass remote, I took mine apart, found an old piece of film negative( Kodak), and placed it over the remote window, put it back together& Voila!, You see it clearly, and tones it down a lot!!!

Good video. I have heard nothing but great things about all of the d4s JP amps. I hope to get a JP33 amp in the near future when my electrical upgrades are done.
Got the jp8 and jp84 combo in my wife's tahoe. Jp84 is running 4 deaf bonce neo 6.5s and sundown tweeters in the doors. And they absolutely scream. Crystal clear and loud af. As far as the jp8, it's breaking in 2 alpine type r's currently and it pounds. I have a second one ordered already. Then they will be powering 2 American bass xfl 15s.
I sold my DD1. It does what it’s supposed to. But I have an OScope too. Which i like better. It just gives you more information. You can see the wave start to clip right before the DD1 flashes.
Just to be clear, DD1 light is Distortion, and the JP8 light is Clip. They are not the same thing. Technically, distortion should come in before clipping, so I wouldn't call the JP8 light accurate, but it IS conservative on the good side of things.
I’ve had this D4S JP8 pushing a single 10” Skar DDX DVC2 in a factory Skar armour coated/ported enclosure with “unbelievable” results pushing my 10” sub really well!#D4S#JP8🔥#10”SkarDDXDVC2#🔊❤️
I run a couple jp23's at 16v and they take it all day long and push out some SERIOUS power for a couple amps rated at 2300rms. I only drop to 15.2v at max output so I have that 14.4 rating all day long and clamp 3000+ watts out of each. Gain matched pushing 2x sav2 15s each at .5ohm - rising to around 1.3ohm
Hey there 👋🏻. Could you make an extensive video about cable connections and materials? Like battery terminal connectors, screws & washers, ferrules and lugs?

And you actually have the knowledge and means to do some measurements of resistances and electrical conductivity!

If I give you a number, and I am wrong, that will cost you a lot of money. So I am not gong to do that. You definitely have enough power on tap to find out.
@@DIYAudioGuy thank you for responding, I was just curious as to what they would handle. I had 2 MTX 10 inch 55 series dual 2ohm 400rms with the same amps and those things were no joke!

Thank you for your help and time. Love your videos my friend!
What size fuse u running on that amp ? It says 120 in manual? I just got this amp and haven’t hooked it up yet. I have stock alt, but secondary battery . Would u say 120 is to high ? I reached out to D4Sound but haven’t heard anything back yet? Thank u!

@@DIYAudioGuy also use cheap tinted cell phone screen protector. Can cut with scissors would be cheaper then buying tint can be bought for like a dollar.
Mount it in the center console or if your vehicle actually has an ashtray/cigarette lighter that opens/pulls out of the dash, you could mount it in plave of the ashtray (assuming you don't ever use the ashtray).
The JP8 has more features. And it's been well documented that it can make plenty of power. At the current price it's an absolute steal, I would pull the trigger.
Im looking for a 5-channel amp with optical input that wont break my bank! (Example: JL Audio and Alpine $$$$$) Have you done in reviews yet on these type of amps? Any companies that we haven't heard of that offer digital in? I ask for ease of connectivity and sound rejection.
Optical input is very rare like he said. Typically not necessary to have on an amp, as source units with optical are designed to be sent to a DSP, and then analog out to your amps. What makes you feel like your RCA's are going to be so noisy that you need optical? Unless you're competing, there will be no need. But if it's a must have, then check into Helix DSP's. Cheap and optical do not belong in the same sentence, so I highly recommend you reevaluate your install and needs. Remember, optical only rejects noise from your source unit, to the DSP...so proper installation of your RCA's, grounds, and drains will reject just as much noise. They will not remove amplifier floor noise as well, which is the issue that most people have on a budget
