[@tatoo3796]

Just a thought here, but when you convert the DC to AC the AC doesn't need huge wires to transmit properly, I believe that's why the 8 gauge wires on the output.

[@wal]

It’s true

[@mrh7027]

@@wal Some dummy math? 8000W over 1 ohm will recuire 90volts RMS (AC). That will need the amplifier to supply 90A RMS (AC) to the speaker wires. (90 x 90 = 8000) The same amp will probably use about 900 Amps on the power cable. (65% efficiency class D) (13.8 x 580 = 8000, but for 65% efficiency 580 / 0.7 = approx 900A So if we make a calculation to keep the same power loss in the speaker wire as in the power wire and assume that the power wire is about 5 times longer than the speaker wire. 900A is ten times as much as 90A. So, the speaker wire only needs to be a tenth as large in area for the same power loss. And to that we have to add that the speaker wires are most commonly shorter. In this case five times shorter which makes it only have to be a 1/2 of 1/10 which equals to 1/20..... So, if you, in this case, use 3 feet (appr 1meter) long speaker wire (back and forth = 6 feet (2 meter) of area 8 Gauge ( 8,4 mm2). And use 12 feet (4 meter) two parallell 000 Gauge (2 x 84mm2) wires from the positive battery terminal. There will be equal loss in the power wires as the speaker wires. So, the speaker wires is well worth considering to keep very short, just as well as putting extra batteries/caps close to the amp in my opinion. But the power wire must be adressed first, otherwise the output of the amp will be reduced regardless of the speaker wire area. I think, as you say, 4 Gauge speaker wire terminals would suite this amp better. Please excueeze my poor engloiise, and maybe poor math :) Always impressive to watch your tests!

Tiffany style or panel mount RCA's are more robust as far as pushing cables on and pulling them off. The other style is soldered to the pcb and over time the stress can crack the solder joints. Its not that big a deal, but the panel mounts have a small advantage.

I love chinese gear, and when your use amps as tools, like for SPL? Great value, and great power at a price you can afford to buy spares? Easy to repair? Its a no brainer. Looks and performance for me go hand in hand. And I like knowing that if something does go wrong with a custom install? I can call the company for a repair. That really matters to me. Custom installs are a mess if you install them just for the space, so having a solid company behind the amp really makes a difference for me. I like American made / Built hardware. Glad I'm in the point in my life where I can get made in USA gear when the need arises. Its pricey. But I tend not to let go of old hardware. As each has a story.

[@thomasnygard2334]

It is gain matching- think of the gain as a matching tool not a volume tool. If you are under the overlap less power over on overlap and you clip the amp. Clipping is when the audio wave gets clipped of making it square instead of being round and smooth. I.E. clipped square waves actually turn the voice coil in to a heater coil sticking it at the top or bottom of the stroke. If clipped long enough the coils glue will burn and then you have a slinky or in worst case a fire. It is more complicated than that. But as a simple example there you go.

[@williamkillingsworth2619]

Test the 2/4 ohm with out the limiter on. I bet it makes rated a 1%. I bet the limiter kicks in at .1%

I've got a question for you, if you'd be willing to answer. I've got an old Lexus, running a stock 8" open-air subwoofer with ~40W RMS. I want to, at some point, upgrade to a more powerful sub with an amp dedicated to that. I don't know what power, or even size, I want to go up to, but I figure 100w RMS would be sufficient. What would you recommend as the best budget amplifier for me?

[@LoudFiat]

They still use master/slave instead of primary/secondary?...

[@robertclark6166]

Your .8 uncertified was actually at 1. Probably why you got the same power cert and uncert. No biggie I'm about to order 2 of these with the plexiglass bottoms.

[@wal]

My bad, lemme check the 0.8 uncert and I’ll post in the video description

[@robertclark6166]

It's gonna be the nut/bolt situation all over again. Lol I know how people can criticize what you do. Keep up the GREAT job you do. Also love the short vids you drop on the second channel always informative. Thanks for what you do for our community

[@SirStickybuds]

@@wal YOU BIG DUMMY! LOL

[@wal]

@@robertclark6166 Ha I hope it's not as bad as the nut/bolt thingy. Geesh! Thanks, I've got a ton of vids upcoming for the 2nd channel, so you get more WAL all week!

[@nathanielnelson1846]

I'd love to see a dyno on the ampere 7500.1

[@wal]

Thanks for the suggestion

[@bandpassmess]

Damn back in the 80s this amp would have been a dream someone thought up ! The price is insane! Now if subs would quit being as big as manhole 🕳 covers !

[@wal]

Yeah this thing would’ve costed $25000 back then!

[@MacRilla]

On the extras your uncert test was at 1ohm not .8 but otherwise good vid. Thanks for the hook up Big D

[@wal]

Yeah big dummy here. I updated the video description with the corrected info

👌😬👍

[@floydwilliams3321]

You had the dino set on one ohm On the clipping test

[@wal]

Good catch 🤙

[@Casey8Caldwell]

Will you test out some of the jp series amps the jp63 and the jp83

[@wal]

You KNOW they are coming!!

[@justinhiggins2210]

On the clipping rating for 0.8 ohms your dyno said 1. Ohms. That might be why it was lower than expected. I'm gonna say it again blah, blah, blah I love these videos.

[@wal]

Oops, I updated the pinned comment with the real result

[@justinhiggins2210]

@@wal thanks I guess I jumped the gun..

[@DangaRanga]

Would you be willing to comment on how long it took to get the amp?

[@wal]

About 2 weeks. I ordered the 7500, 4000 and a 125x4

[@DangaRanga]

@@wal Oh wow, thats exceptional. been wanting to retire my 1100.1s and these may be a decent cheap replacement, that or smart 5k's (realistically 5k per sub would be plenty)

[@ericrawson2909]

Is this true RMS power? Or is it instantaneous peak power? Either way, your DC supply needs to be hundreds of amps. Not long before your car battery is flat, it's like running the starter motor non stop.

[@wal]

Yes all tests RMS power. I have a large lithium battery bank capable of 1500A or more pulls at 15VDC

[@ericrawson2909]

@@wal Incredible. About 25 years ago I fitted a 500W system. Loved it, I could feel my hair moving with the bass, and all mirrors blurred with bass beats. Went into a shop, left my daughter in the car and she hammered it. When I got back to the car, flat battery. Manual gearbox so I managed to push start it.

Takes power to make power. That’s right!

100%

[@dylancurbjumper]

What % THD is considered clipping?

[@CL-yp1bs]

bro in the extras at the end one of the tests u said was 0.8 ohms but it was actually 1 ohms...

[@wal]

9624 at 0.8 uncertified

[@chrisfiske]

The .8 uncertified was actually at 1 ohm lol... you did say .8 but it was at 1 ohm on the dyno

[@wal]

9624 was the 0.8 uncert run. Sorry about that

[@512juancho]

How can i buy one of these?

@@wal whats a good budget amp that will do 2000rms @1ohm under $250

[@Therealrichdude]

What's the best/loudest budget amp you've tested?

[@wal]

Watts for dollar? Blaupunkt 4000D, but I would not recommend it. WUDU 8808.1D prob #2, still taking a big chance with cheap amps

[@jimt5683]

Best high wattage bang for bucks?

[@ripnwithbign9211]

Not bad considering you can get 2 of them shipped to your front door from China for $1500

[@wal]

But if you have issues you need to find your own tech

[@southnyourmind]

So this amp... Is the same amp as a deaf bonce AAK 8000? Cause... They look the same.

[@wal]

Could be a copy, I haven’t seen the dB amp to compare

[@Facekicker]

Huge power! Nice!

[@wal]

I linked your vid and website in the description 👌

@@wal much appreciated!!
