So true about the outside temp. Love when winter comes around to cool the subs off and shake snow off the ride.

[@mikellewis2346]

I've seen guys run there AC with tubs to there amplifier to keep them cool.

[@BrianWaller-qe7gr]

Yeah winter here I can literally pound on the amps for an hour and barely even warm.

[@TheRepos296]

Great advice, it's always better to have a little headroom as you said meaning more power to combat box or impedance rise, and it would also be advisable to take advantage of the technology out there like smart amplifiers that would play whatever power they are rated at, at 4, 2, or 1 ohm loads. Taking into consideration the individual is on par with proper electrical for their equipment.

[@ceciljones1248]

I rather blow a subwoofer than a good amplifier any day my rule of thumb is always buy a amplifier twice the power of a subwoofer set the gains way before clipping and have a nice day

[@BrianWaller-qe7gr]

Yep I finally learned to buy a more powerful amp than needed then just set the gain to avoid clipping

[@winnsautomotiverefinishing]

Do you have a distributor in Australia that I can look into for some of the D4S products for a system I want to put into my car at a later date😊

[@RyanBassForLife]

Nice vid I want a JP63 😎👍

[@PunisherOfDeath101]

I want one too... Its efficiency vs other jp amps has me doubting. The 33,43,83 are more efficient. Maybe jp can chime in on why this is.

[@davidsuttles3737]

I have 3 Skar audio SVR 10 inch dual 2 ohm subs paired to a JP23 amp. I feel like they are under powered. I check the ohm load and it seems like the ohm load is all over the place when checked never stable. No I'm not playing them when trying to get ohm load. I wanted some close to 1.3 but its seems like they are closer to maybe 2 maybe 3. Not sure like I said. I have tested one at a time 2 measure like 2.6 the other closer to 2 ohm but when connected together they just bounce all over. and yes I got them all from you down4sound. I might just go with 2 12's next.

Bro, no need to make a video. Just link BJ 🤣 Thanks for what you do! Always good content and good answers!

[@bigk3355]

I just bought a Jp 13 what is the input rms can take from head unit. I think mine is 2volts rms. My question is do I need a line driver

[@NasierOmran]

So basically a amplifier amplifies the energy to higher wattage output? Can it be used to power other devices than sound related tech.?

[@dougloyd5988]

I’ve always been more amp than sub rms. Never have to max out the amp. Definitely buy quality and rated power equipment.

[@VerdantStone2]

Is there going to be a jp53 ever?

[@TREX239-fs6cp]

Whats a good size amp for 2 12 inch subwoofers 800 watts

[@thetruth1446]

If I have a 1000 watt amp on 2 12s, each speaker gets 500 watts right?

[@1904audio]

This in general for daily drivers the bass head community will push either or to the limit and beyond lmao

[@gaugezorn2081]

hey man i’m trying to find an amp for my setup. i got 5 evl 15s not quite sure what rms amp i’m needing since each sub is 1250w rms and max is 2500. i’m wanting to put as much power to them as i can. what would you recommend

[@NoName-gk2sj]

I’m thinking of running 1 xspowerd4800 under the hood and 1 in the trunk and a 290A alternator with (2)2/0 wires each battery gets there own 2/0 directly from the alternator or should I put 1 wire from alternator to from battery and 1 wire from front battery to rear battery with 2/0 wire and 1 500A isolater in between batteries. I’m going to be powering 2 Solo X 12s the new ones. With (2) cxa1800.1

[@zaccannon6094]

What I still don't understand. Is if I'm running 6 speakers that are 200 watts rms, do I multiply the 200 by 6 and that mean I need a 1200 watt amp? Or do I still only need about a 400 watt amp? Cause seems like to me if I have one 1200 watt amp feeding them 6 speakers. Then all 6 will be getting 1200 watts. When they only can handle 200 rms and 400 max. I just can't figure it out.

[@Jbel426]

Hey jp how bout matching mids with lows so the mids aren't over powered by the bass would 300 rms mids for simple 4 door 1 per door and 3000 watt sub be a gd combo

[@blackhornet25]

Recommendation needed, I have 3 rf t1s1 10s 1ohm svc. The rf 1500.1 goes into thermo protect. Which jp amp will push those subs and handle final ohm load?

[@559pyroo]

“For example “.. Soo What if your voltage is at 13.5 and wanna buy a Jp23v2 . Can you still use this amp since its rated at 14.4v ??? Or

[@thenotoriousrvh6091]

You might as well have been talking to a wall lol. Everybody's some dang hell bent on thinking the lower the impedance the more power they get, and all knobs right.

[@edgargzzg4495]

2- sundown X v3 8” dual 4 ohms, in a custom ported box in a crew cab professionally installed, with sundown s.I.a. 3500 amp, amp keeps clipping at high volume, should I upgrade the amp??? which do you recommend ??

[@nuevo_mexico_cruizerz]

Hello can you help me figure out what amp of yours i should run . Im running 4 12" Kicker Comp R DVC 2ohm. They are 500watt rms 1000 peak. I wanna do a final 2ohm at the amp

[@kidsavage86]

I'm about to grab a jp23 +jp8 combo saving my pennies now and do you like American bass is what I'm running XR 12s about to get godfathers or hd

[@marckendrick3163]

What A/B JP amps would you run active on the JP 3way 6.5 set?

[@2015gtbass]

So dose this mean. For us daily bangers. That the sslt4 would be a good match for 2 12" xv3's

[@runfast8172]

how much should there be on a u8 d4?

[@russellcrabtree5314]

But you underrate and if someone orders to match rms a person could overpower the subwoofers causing the motors to overheat. Don't get me wrong your amplifiers are fantastic, but maybe you should change the rms ratings to match testing.

[@BrianWaller-qe7gr]

Exactly the jp33 can do 5k watts so that 3300 rms is grossly underestimated. If someone buys a jp33 and doesn’t know what they’re doing it can easily blow a lower end sub.

[@kidsavage86]

American bass tuned to 30 on decently done electric took 8k Then parker on KZbin hit his with 10k on one sub they over charge in Brooklyn NY for sundown and Orion so American bass is my go to to

[@THELIFEOFPRICE]

You should order it from www.down4soundshop.com

[@Pittsburgh-412]

I usually do 1 1/2 the power of the sub to the amp. If the sub is 1,000 watts then I'll use a 1,500 watt rms amp

[@thenotoriousrvh6091]

Great rule of thumb 👍

[@Wr3K_6996]

In my car im running 4 svr 12s at 1ohm, there ran on a rp1200, and I don't think it honestly puts out enough power to push them, they play loud but the amp gets to hot

[@jasondecluebass1012]

Jp the best great job

[@tammyforbes2101]

I always buy way more amp then I need so I can run it at a lower setting so it stays nice and cool! Just gotta not over drive your speakers or subs! If you hear distortion or you been jamming a while turn it down let those coils cool!

[@mikellewis2346]

A 2000w at 1ohm amp running at 800w at 4ohm will run way cooler then running a 800w rms amp at 1ohm correct ??? I'm looking at some amplifiers an see the price isn't that big of a difference between the say 1000w versus the 2000w amps. Is it worth the extra money to run a bigger amp at higher ohms an maybe not pushed to the maximum. I'm looking at the efficiency at 4ohms is normally higher then at 1ohm.

[@BrianWaller-qe7gr]

Efficiency is what keeps amps cool. If an amp is highly efficient say 80%+ it will run cooler than a less power amp where the efficiency is below 70%. Efficiency is calculated based on how many watts it produces divided by the amp current draw it takes to achieve that wattage

[@mikellewis2346]

@@BrianWaller-qe7gr so for a extra 50 buck's or so it's worth getting a larger amp and running it at 4ohm to have a really cool running amp. I'm not looking for maximum power, butt I wanna run a 1000w rms efficiently as possible. Thanks for the help.

[@BrianWaller-qe7gr]

@@mikellewis2346 a higher power amp will inevitably have higher power even at higher impedance like 4 ohms. Just saw the dyno video of the jp23v2 rated at 800 rms at 4 ohms did way over that.

[@mikellewis2346]

@@BrianWaller-qe7gr ya there best amps.

[@michaelporter9695]

For subs, I match RMS amp to peak , mids = or +25% rms, tweets = or - 10%... when music is playing, not spl comp burps, your impedance goes so crazy (box rise, imp rise, etc) that without clipping that I've never had problems. (Running sundown SALTs, Deaf Bonce Arn mids and tweets, Sundown Z15v5 subs)

[@charlesriston8972]

My 2021 Orion HCCA 3000.1 is a 5000+ watt RMS amp........... You gots to be Careful lol😅😅😅

[@PhobosPlace]

i have 2 15in skar svr's i was thinking about getting a JP23 v1.5 elite to push them, which is probably over kill but worse case it blows the sub and i buy the ddx or evl. at this moment i have my rockford fosgate punch 200ix pushing them. will probably get a d4s mm1004 for my pioneer 6.5 coaxials in all my doors.oh in a 2007 honda fit lol

How good are those subs? They hit hard.. I was thinking of getting some 12"s

[@joshlyons594]

love the content brother

[@stevenstuart4813]

Well said !

[@shawnsanderson3695]

Thanks JP

[@BrianWaller-qe7gr]

It’s always safe to go over rms ratings of your sub by 25-30%. Reason is to account for box rise. So a 3k rms sub you can safely get an amp of 3500 rms. Because the sub won’t actually see 3500 because of box impedance rise

[@jasonmillz8628]

Much love bro

[@DGGuaglianone]

If you smell smoke turn it down and don’t clip your signal. If you follow those rules your subs can take way more power than you’d think

[@PunisherOfDeath101]

Rule 1- Wire to 2 ohm or higher. Ohms law Rule 2- Takes power to make power. Alt, battery, and caps. Rule 3- Get a reputable box builder before you buy subwoofer. Space decides everything. Most important rule/fact is people are stupid, he said she said is the reason why car audio is snake oil in it most venomous form.

[@izhwzkct]

We can’t hearing you. All is noise over there.

[@dcaudio1]

I think what people don't understand is clean watts versus dirty watts....for example if you ran a JP13 at 1 ohm to get max power (2000 watts ) that amp has very little resistance on it so its playing very wide open and getting hot and most likely clipping on certain nots....if you ran a JP 63 at 4 ohms and its you get the same 2000 watts but the amp has high resistance and playing very cool with a lot of headroom so its controlling the subwoofer much better. I always run my amps way over the subwoofers power rating and tune it back to match the subwoofer. People think yeah your "wasting power" i look at as im "controlling my sub and letting the amp breathe" see the difference....amp last forever, doesint get hot, subwoofer loves it, and it sounds much better for all those reason....running an amp wide open means you get almost zero headroom, gets hot as hell, looses control of the sub at points, and will eventually fail from heat from either the sub or the amp...or both. These are the facts..I run a b2 audio rage 2500.s on 2 JL audio 10W1-4 at 2 ohms....it sounds awesome, it breathes, the subs love it, and it DOES NOT GET HOT!!!!!!!!! your welcome....
