Thank you for your work sir. Candidate suggestion: Taramps appears to be usurping the SMART series and replacing with Big Boss RGB line. At least that's what Amazon stock often suggests. Would be interested to see if the RGB is just an added feature, or a case of "add pretty, cheapen function, raise price." --- These JP amps have been looking like solid performers. Would love to see a "secret shopper" JP53 follow up as well ;-). Maybe a little jaded but after Sony Watts in the 90s and modern internet campaigns, I'm a bit jaded on "true rms" power to an average consumer.

[@THELIFEOFPRICE]

Glad I got around to watch this because I found a problem right at the beginning on two colors missing on the jp73. We have the 2 missing colors and listing them now! Glad to see they performed amazingly and also glad to see your cons list getting shorter and shorter for our amps .... we listen!

[@wal]

Awesome!

[@derekgardin1512]

I like how you actually make the changes, like with the amount of turns for the bass knob and the nicer caps etc. The fact you have so many colors for every model is crazy and no one is doing that and you'll probably keep that as something unique about your brand.

[@JayTR_10]

Big Dizzle doin your thing! The JP 53 is easily an 8k JP 73 is a 10-12k all day. 20k watt burst at 0.5 is ridiculous for a 7300 rated amp.

These D4S amps are so reminiscent of the Rockford Constant Power amps. They have so much reserve power and great power delivery at 1% distortion. Sure, they’re great for SPL, but they’d do very well for a “budget” SQ system too. 1KW with a nice sub and box is a LOT of bump. Better call Safelite and get your wallet out. These amps are no joke!

An SQ system doesn't need 10k watts and none of the nice SQ systems had anywhere close.

What’s crazy is, I posted a comment a week ago about my purchase of the JP53. I stated that the amp was indicating a Clip In light at volume 22 (2.1v) out of 40 (4.4v) and my HU is clean up to 39 (3.6v) and I set my gain with a SMD. I asked for some feedback thinking I’m doing something wrong. Well today 8/22/24 my comment is not on the comment section anymore. So now Big Dee and JP are removing comments that alerts people that the amps may have some flaws being it’s a new product just released. That’s really low of these guys. People spend their hard earned money and can’t get honest feedback and CS from D4S and his affiliate Big Dee. Never again!!!!!

I have the jp3 in my wifes 2024 rav4 pushing an NVX 12 in a sealed enclosure. The amp has a lot of power but its fan runs all the time,and it thumps on turn off. I swapped it out with a PPI 1000.1 problems gone. I love the bass remotes and colors of these amps! What are we to do with this much power,weld?? lol
