Amazon.com: Boss PH5000D Phantom 5000 Watt Class D Monoblock Amplifier with Remote: Car Electronics

i was lookin around on amazon and i stumbled on this little guy... i think its way over rated or a ****** amp im buying a mofo122x and i want a nice amp to power it what yall think of this guy?? would i need to replace my alternator and get a cap for this? itll be running at 2 ohms

i also think my deck puts out more power than that amp lol jk

your deck probably puts more than your power acoustik amp as well. lmao kidding

RMS power output: 1800 watts x 1 chan

On another site, prolly would do a solid 1200-1500

mofos are loud but don't hit deep buy a skar vvx and obsidian 12d2 a brand x XFL 12 or a lanzar opti1232 same price but these get loud like the mofo 12 and hit 10x deeper and just have better sq all around for an amp go with a hifonics brz line u can get for around that 130 mark

Pa amps get loud lets not get to over dramatic with the pa dissing

It has 4-gauge inputs, and 80 amps of fusing... I'd expect around 1200 watts RMS

Being Boss though, expect that to be at like 5% THD...

I'd sh*t my pants if I came across a true 5k rms @ $130.

umm ok but if you calculate it out at 10 amps of fusing for every 100 watts of power then 80 amps is only 800 watts,so where are you getting 1200 watts from?

My Mofo's get loud and deep. All who are bashing probably never owned any. They are decent for the price. As with any sub its all about clean power and the ENCLOSURE. I'm powering 2 12 in Mofo's on a DAT 2500.1 and they're taking it with ease. Now Boss is a different story.(JUNK)

My initial guesstimate was actually a bit too high after doing the math, but where are you getting 10 amps from every 100 watts of power??

V (voltage) x I (current in Amps) = P (Power in Watts)

So with the engine running, we'll say 14.4 volts of input power, and we're limited to 80 amps of current (continuous).

14.4 x 80 = 1152. This however assumes 100% efficiency, which is impossible. Boss doesn't list the efficiency of the amp, so I'm just assuming the typical Class D efficiency of 80%

So take 1152 x .8 = 921.6 watts

Pure garbage!!

*update - looking through the photos on SonicElectronix, it actually has 4-40 amp fuses... Thanks Sonic... thanks...(lol, the specs only list 2)...

(Boss PH5000D 5000W Max Class D Monoblock Power Amplifier)

Soooooo

14.4 x 160 = 2304 watts

calculate for 80% efficiency

2304 x .8 = 1843 watts with engine running

ok but there is a much more accurate way to measure power which i learned from a 30 year car audio veteran

V(ac)/A(ac)= IMP then V(ac) squared/IMP=POWER(WATTS) that is a much more accurate measurement

You guys are forgeting one very important factor in your formula.. Its BOSS
