car audio amplifier PA-80D P.M.P.O 1000w (review&testing) 

I am doing the reverse engineering for this board. I'm an electrical engineer as well as English teacher. When I'm finished I published on RU-vid. You may like to know these are not MOSFET transistors. I guess some tweaks might make this become a bit stronger.

Thank you for sharing your idea sir.

AB po.

Pwede namn po kasi ung mga ganyang amp po madalas working namn po cya from 4 ohms to 16 ohms common po sa mga class ab amplifier

Class D PO BA YAN AMPLI MO

Depende po kung ilang ohms and watts ang gagamitin nyo po na sub pero napang test ko po cya 2pcs d10 200watts 8ohms each ok namn po.habang tumataas po kasi ang load maslalo lumalakas ung kunsumo sa battery na.rated po nyan nasa 100w rms more or less

Yes po..pero mabilis dn mag init.

Dpende po sa voltahe na inilabas nya if lagpas 1v na dna po maganda un maninira na po talaga un pwede may nashort sa board nyan or nadikit malapit sa input section or sa linya po ng pre amp dapat na check po kasi may capacitor po yan sa input.meron din po pagkakataon na sa 24v ginamit then kumuha ng supply sa 1 battery lang para maging 12v kung ang napagkuhanan ay + ng 24 at ung negative ay kinuha sa series connection ng battery sure po un from negative ng amp at body ground ng sasakyan may makukuha na supply

​@@carljosephsantiagoboz 12v dc lang po or single battery lang gamit ko, un neg voltage supply po nia at un common ng input audio nia mataas ang voltage around 12vdc po... bakit kaya...

Pls Try to search sir in any online store like aliexpress or alibaba

Depende po kung watts rms po malamang hindi po.

Meron po sir.madalas nag kakaron po nun lalo na pagmabilis takbo or naka idle pero pwede po mareduce un lalagyan po ng filter coil sa b+ po.e2 po kasing amp na e2 wala po ganun dpo tulad nung mga v12 at x12 amp

@@carljosephsantiago ok ok tnx

Smps 12v 30A 350w po sa online shop po meron nasa 700 pesos up po un.masmataas amphere rating masmaganda po

Pwede n po ba 12v 6A.

N power supply

Kaya namn po kaya lang dpo mabibigay ung full potential ng speaker almost 160watts rms lang po sa 4 ohms yan

Hindin po.hanggang 14vdc lang po

Pwede po b jan 12v 5ampers

Kung ang pagbabasehan po ay design.yes po malakas po cya kumpara sa mga 12v ic type amplifier kasi ang design po nya ay gumamit ng dc to dc inverter na kung saan ung dc to dc na inverter ay pwede po magamit sa mga high power amplifier.pwede nyo po icheck ung ibang video ko para makumpara nyo po na masmalakas cya compair sa mga ic type amplifier.meron po ako video na dc to dc inverter.pls visit my pages salamat po

@@carljosephsantiago wow ok sir tnx

4to8ohms po

Not included po ang mga wires..unit only po sya

Pwede namn po basta Configure nyo po ng 8 ohms ung bawat sub para dpo mag init ng husto ung amplifier.para pagnagparallel po ay lalabas ng 4 ohms

Kaya nman po,yan po ba ung 1 pair lang ang opt. nasa 50 to 60w rms namn po yan.magdedepende pa din po yan sa supply nyo cyempre kung 150w po yan dapat atleast 12volts 15 amphere po ang power supply ang gagamitin nyo po

Opo. gagawin ko lg pang bass. salamat po

Pang boom box po kasi ung mga ganyang amplifier normaly sub application po talaga yan

@@carljosephsantiago ahh, kaya pala, maraming salamat boss.

@@carljosephsantiago boss, pa recommend po ng car amp na nasa mga 1.5k to 2k na halos mrv 705 ang tunog or kahit mababa sa mrv 705.

@@carljosephsantiago lalagay ko sa tricab ko boss, lagpas 2k kasi ang 705 or 805, baka may alam ka na brand at model na kahit medjo mababa lang sa 705 pro goods ang tunog at power boss, salamat.

@@Nanel727 madami po ganyan design na amp kaya lang po puro mono.amp lang po.normal po kasi na 2k up ang presyo ng car amplifier kahit assemble pa po paki check po sa ibang video ko ung dc to dc inverter 12v lang din po gamit ko dun

Nasubok ko po sa 2pcs d10 350w 4 ohms pero naka series po configuration of 8 ohms pag naka parallel po kasi parang flat iron sa init 2 ohms nalng po kasi un

Yes sir.i think there is a little bit enhance in the sound quality.maybe next time if i have spare time to build a subwoofer box in this amplifier i use parametric equalizer to give more sound quality output.thank you

I have the PA-80d as well but mine has a black PCB instead of green like yours. Everything else seems identical. I don't use the LPF on mine because it does cut out too much signal. I have tried it with one of those 7 band EQs for car audio and it works much better. Right now I have it hooked up using a sub out RCA from my Yamaha AVR to a LPF preamp then to the PA-80d amp and that squeaks the most power out of it. I've measured around 200-220 watts rms with a cheap oscilloscope. It's powering a 600w rms 12" Audio Legion dual 2 sub wired in series to 4ohm. Shakes my entire apartment!

Yes sir addtional pre amp can increase sound output.but it depends on the power supply use.so it is better to use high current power supply o high current battery to give better sound output

@@carljosephsantiago I'm using it with a 600w computer ATX power supply. I desoldered all the 18awg wires off the PCB and replaced the 12v with 8awg wire. It delivers 46a on the 12v rail. I also power the preamp from the same power supply and I added a usb-c to the 5v rail to power a Bluetooth adapter if needed.

It is nice sir 12v high current regulated power supply is better it give less noise.itry that concept wayback 2013 i use atx power supply but instead of using 1atx i use 2 and connected in parallel to increase power but not in this amplifier by the way thank you for sharing your idea sir.pls support my channel thank you again

Need po bumuli ng socket if ever na ayaw nyo po putulin ung dulo ng wire ng charger pwede po hanggang 15vdc.pag lumagpas po pwede na po masira ang amplifier

Dpende po sa impedance na ginamit na dummy load kung 4 ohms po pwede nasa 160 watts po yan design po kasi ung mga car amp na loadan ng 4 ohms speaker lalo po sa subwoofer

Madalas po kasi naka connect un sa ignition or sa car stereo dun po nakuha ng 12vdc supply bale po ung b+ rekta na sa positive ng battery bale kahit switch na maliit pwede ilagay or jumper wire na kahit ano kulay

Bale nilagyan ko lang din po ng non polar capacitor 4.7uf/100v tapos naka select po ng fullrange ung amp

@@carljosephsantiago may speaker kasi ako dito na japan bookshelf pwede ko kaya sya i connect pang mid hi?

Good day maybe It is range from 80 to 100watts rms base on the component install in the board

I saw a test in which it gave 170 wrms.

Yes sir it range from 160 to 180w rms @ 4 ohms.so if you use 8 ohms speaker it can be ranges from 80 to 100w rms and it depend in the power supply use.car amp is design to use in 4 ohms load

Deep cycle battery po pang solar po 12vdc 18AH po

my ganyan ako bigla nlang namatay pumutok fuse ng amp

@@gloriaromero125 check po ung mosfet ung 2 po sa ilalim na 3 pin irfz44 po ang part no.check din po diode baka shorted din

Po

Gagamit po kau ng power supply 220v to 12v atleast 6 amphere po

Pwede n po pla ang 6amper pataas po ba

Hello good day po.dpat po naka select ung switch sa hpf para magka vocal at tweeter pag lpf po puro bass namn.pwede po kau gumamit ng parametric equalizer para macontrol nyo din ung treable.midrange at bass

Yong equalizer po ba ay 12 volts din

Im sorry but i order it from online shop

6inches 40watts@4ohms po

Ano po box ung sa sub po ba.pwede namn po gawan

@@carljosephsantiago Yung parang casing na aluminum nyan sir. Kasi parang open lang yung likod. Parang alanganin ako magburas sa baffles tapos doon ko kakabit. eh malakas ang vibration nun baka masira lang agad yang mono amp.

@@Purowalangkwenta Required talaga sir lagyan ng air proofing yan if lalagay sa subwoofer box, much better kung naka seperate siya sa airflow ng subwoofer box kumbaga may sariling cabinet sa custom box. Yung sakin nilagay ko lang sa box kung san naka package yung amp, safe naman nilagyan ko rin ng fan, nakahiwalay siya sa subwoofer box. Mag 1 year na sakin sa bahay and recently nilagay ko sa sasakyan, maganda power output kahit 13v lang supply ng koryente ko.

Check fuse po.pag busted try nyo palitan.pagpumutok uli check mosfet ung dalawa po sa ilalim irfz44 madalas no.pagshorted check mo po mga diode sa paligid ung pwm i.c nyan nasisira din po tl494 no.nun yan lang po muna.pag may shorted po sa main amp mag protect din po yan

Depende pa din po sa speaker na gagamitin.meron lang po na selector yan para mawala ang kalansing at humina ang boses pero dpa din po solid na full bass

Bkit mhina ang bass

Sabi po kc sa rating MALKAS daw bass po

Try to "higher your picture quality" sir.thanks

25% of the pmpo is rms.but as you can see in the design dc to dc inverter have 2 pcs mosfet so the main amplifier cannot deliver the true rated power and the dc to dc inverter depends in the battery capacity to produce more power but if the dc to dc inverter rich the limit the mosfet will get damage or burn

We replace the MOSFETs , the power transistors from the dc-dc converter and the diodes so that I can give more power.

Yes sir but not only the mosfet but also the torroidal transformer as you can see the diameter of the core is small.to increase the power modefy the core and then winding plus the mosfet

Yes,that amp is mono

What do you mean by mono only

Good day sir mono means single channel amplifier

Good day sir.plz check online for that item.i buy that on shoppe ph

Good day po ang design po ng amplifier ay dual operation pwede cya gamitin pang low at pwede din full range kung makikita po ninyo meron switch na maliit ayun po ay cross over may naka lagay na low pass filter(lpf) para sa bass application at full para sa (fullrange) 2 way application.sa latest topology ng kahit anong amp ang ginagamit na po na pang low or bass application ay mga class d amplifier na.pero dahil po yan po ang alam ninyo at narinig nyo.salamat pa din po sa pag comment
