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.

Ohm's Law says watts / volts = amps, so 1000/12 is 83+change -- damn! I hope you have a big, phat alternator! So fuses have to be rated somewhat higher than device load, you need a 90 amp or 100 amp fuse -- what style I couldn't even begin to guess, normal automotive fuses don't go that high. If this is a new install, make sure your power wires are heavy enough to handle the load. A fuse's job is to blow before the wiring catches fire. The longer the wire is, the thicker it must be. Electrical fire is a catastrophe so make sure your wiring is adequate -- I know it's hard to believe but the power wire is actually more important than the speaker wire!

be sure the amp is located in a well ventilated area as heat build up can cause a safety override to cut power once temp. reaches a certain point. amps do generate heat though so if you dont think its cutting out due to excessive heat building up, i'd definitely get a power capacitor to help keep a steady supply of electrical energy available for instances where the bass hits really hard or for prolonged periods of time. if you have a power cap already make sure it doesnt need to be upgraded to function properly. hope this helps!

its not supposed to do that,read your manual,it only reads memory cards,,it plays dvds Power Acoustik PD 103B

do you have it wired in with all necessary wires? i.e.: audio jacks L/R plugged in?
