I really do appreciate that D4S listens to critiques and improves on their equipment. Companies that actually seem to care about quality and giving the people what they ask for are rare these days.

I bought one of these on Aug 30th and got it on the 6th Sept. Hooked up power and ground and remote and powered it up. It was awesome seeing that blue light on. Left it on for about 15 minutes while I went to get my DD1 to set the gains. When I got but the amp was in protect mode. No RCA's and no speaker wires connected. Cycled the amp and still in protect. Disconnected everything and waited a few minutes. Reconnected to power, ground and remote and still in protect. Took the amp out and put my 12k Taramps back in. That worked find. I bench tested the JP93 on a 48ah Headway battery and still have protect light. Having to send the amp back but having problem getting them to send me the authorization email with an RMA so I can send it back. Been a week now and no word.

Great stuff as always. I think Dynamic power is probably the most useful test for subwoofer amps because of the Kick Drum in music. It requires a short burst of power to be reproduced and the better the amp can react dynamically, the truer the reproduced sound, IMHO. This also applies to other, short dynamic program material. I don't know why people would say it doesn't matter. Music IS Dynamic. Unless you're just listening to test tones, Dynamic Power matters. Linear Power amps back in the day has gobs of Dynamic Power available and they sounded amazing. Better than any amps I had heard before them. I know you tested one on here and showed how much headroom it had.

My Ampere Audio AA-75.4 is a great-sounding little amp. Seems to have some good Dynamic headroom in it. And, it was a huge upgrade in terms of improving my system's audio quality. I'd be interested in you testing one or more of their products.

Thanks again for your great videos. I really enjoy watching them.

What a beast!!! At .5 ohm and 14.5v it's consuming1724 amps. Wow

JP needs to send you one of the NEW 10 Channel amps to review!

Adjusting the phase control when you only have one type of speaker playing one particular frequency doesn’t change anything. Phase control comes very important when you are nearing crossover frequencies… The method I personally use is to adjust phase is start with your subs playing a test tone at approximately crossover frequency at a low/medium volume, now slowly increase the gains on your mid bass amplifier, if it gets quieter before it gets louder, you are out of phase.

glad to see the better quality caps, that's great..

That is insane! Well done Down4sound. Thats roughly the equivalent of connecting a speaker to the mains supply to your house.

Bought my wife a jp 5 channel very impressed with the quality

[matts]

Let's waiting for this vid just got my red 93 2 days ago thank u sir

[danrimjob]

Big D, outstanding job as always brother 🔈🔈✊🏻

[darrelldarrell]

Bought their 7 channel you had on your dyno and put it in my hummer. Best amp ive ever uses dude. Now doing a system in my 2016 srx and will probably buy one of these.

[jimmyjam]

I've been waiting for this video thank you!!! Wish i had the money but you can always dream 💪

[phatboi]

Thank you as always for your reviews and tests! You have become the standard in the industry! I always check for your vids before buying an amp. Although, having owned 2 JP83s, I did jump on the 93 before you got a hold of it. I was not dissapointed! 💪🏻

[alanstant]

That's some crazy power there Big D.

[olbakerman]

Another powerhouse from d4s thanks for the dyno once again sir.

[MAD_CarAudio]

I like how they have more than just the min and max values on the different adjustments. Makes finding the frequency you want easier than eyeballing something between 20 and 200 trying to find 80 or 100.

[SuperPhocks]

wow...Thank you for these videos. I make my purchases based on your reviews and tests.
