Need to if I can connect a power acoustik 500w subwoofer to my hometheater system, and if so need wiring diagram

Sub-woofers work on a low hertz as per audio. You have a built-in amp that has a crossover that separates frequencies under 100 Hz. Typical Hertz range is between 20-60. Since you have a built-in amp the black rectangle is a heat sink which helps to dissipate heat away from the internal components and also seconds as a cover to keep debris and other foreign objects from getting to the amp and burning it out.

Hope this helps.

set gain low. the other is your filtering frequency as at what hertz you want to listen at switch threw them for your best sound.

yes, but you will need a significant 12 volt power inverter to support 500 watts

the shown photo is a bit confusing too me , clearly this is an automotive speaker , but in the photo there is clearly a home power cord shown , is this power cord connected anywhere on this speaker ? as if it is , id be afraid that amp has received home power and not car power , as the two are not the same and have tremendous differences and would be quite damaging to this amp possibly unrepairable damage

just hook it up and try it out that will tell you.

Question makes no sense.

you want to use a car amplfier indoors in the house

yeah that can be done very easily
just wire it like you would inside a car but you need to purchase a 12v DC adapter
i would go for one with at least 3A output (the bigger the better it depends on how much u wanna spend) from personal expericance 1.5A works but when it gets loud the amp stops and restarts

NEW POWER ACOUSTIK MOFO-122X 12" 2700W SUBWOOFER SUB

Hello familia_gome,

Those MOFO-15's have dual 1ω voice coils. So the only way you can get 2 of them to present a 2ω load is to use 1 voice coil on each one with the two of them wired in series. Using both voice coils, you can get a 1/4ω load by wiring the voice coils in parallel and then wiring the subs themselves in parallel. You'll get a 1ω load with the voice coils in series and then parallel the subs. Or you'll get a 4ω load with both the voice coils and the subs in series.

Here's a link to Power Acoustik's PDF for the MOFO's. I recommend that you check out the wiring diagrams on page 3.

Hope this helps.
