Amp draws too much power from battery?

Question:
i have a sony xplod 1000 watt amp and sony xplod 1200 watt 12" sub and i have a scosche capacitor hooked up and i still have a major power draw. Headlights and dome lights dim out nearly all the way then gauge spikes and blows the two 30amp fuses in the amp. What do i need to do.

Answers:

about subwoofers?

im asuming its not a new car. That sony amp is only about 400 watts rms, maybe less. If your car cant power it then u might need a new alternator. Yours is probably bad. You shouldnt need a high output alternator for that amp. the 4 guage wire your using is fine with that amp and even a 1 farad is more then enough for that amp. Buying a bigger farad cap may hide the problem temporarily, but it isnt going to fix the problem. Take your car to autozone and have them test your alternator. And if your blowing the fuses inside the amp it may be a problem with the amp itself if you alternator comes back fine. Having installed dozens of sony xplod amps, more come back with problems then should.

if im running 2 kicker l7's what amp do i need?

Where are you drawing the power from? You should be using a 100 amp (12V x 100A = 1200W) fuse straight off the battery. You should be running some fat wires too, like 4 gauge or better.

Why does my amp keep blowing fuses?

help installing pioneer deh-7700 to 04 silverado?

get a higher output alternator

I have a ipod nano idk how i should set the Equalizer on it( i have a mix of rap, rock and techo on it)?

it could be a few things. get lower gauge wires always helps. or get a capictor that is 5-7 farads or more. Sonys always drain mad power from the battery. other, more expensive amplifiies, like JL or Kicker, though supposedly deliveer just as much punch or more, for less wattage.good luck

my 15" vs 2 10"?

FIRST OFF WHAT TYPE OF CAR? IT SOUNDS LIKE U NEED TO UPGRADE YOUR ALTERNATOR. WHEN U RUN THAT MUCH AMPS YOUR ASKING FOR A FIRE OR LOOKING TO WALK THE REST OF THE WAY HOME . THE CARS WIRING WONT HOLD LONG UNTIL IT BURNS THROUGH THE CASING. IF IT IS BLOWING 30 AMPERS THAT IS A LOT OF STRESS GO TO A GARAGE AND GET A AMP READING WITH STEREO. ON THEN OFF BUT IT LOOKS LIKE U NEED TO UPGRADE IT WILL BE IN YOUR BEST INTEREST ALSO CHECK ALL WIRES LEADING FROM THE BATTERY TO MAKE SURE THERE IS NO OPEN OR RUBBED WIRES TOUCHING ANY METAL, AND CHECK ALL GROUNDS. ALWAYS GROUND TO THE FRAME NOT BODY OR INSIDE

To calculate the current draw of an amplifier, multiply the number of channels by the RMS watts per channel (a 2 channel amp rated at 2000 watts RMS per channel would be 4000 watts). Double it to account for amplifier inefficiency (4000 watts X 2 = 8000 watts), then divide by the average output voltage of an alternator, 13.8 volts (8000 divided by 13.8 = 579 amps). Since the average music signal requires about 1/3rd of the average power in a test tone, divide by 3 (579 amps divided by 3 = 193 amps).

Can anyone tell me where I can find the rear woofer for a 2000 cadillac deville other than a dealership?


This is an average approximation of current draw and can go higher. So I would gather between 194 and 289 amperes for this example.

can someone help me with my car stereo system?


The alternator of a:

From all of us in Polls and Surveys, Merry Christmas to all.?


compact car is about 35 amps
mid-sized car is about 65-75 amps
SUV is about 145 amps

Is static noise from amped-up car speakers normal?


Calculate 40% of the amperes of the alternator you have now. This is the average current the car uses when running. Add this number to the approximate average current draw of the amps, and you will come up with the actual size of alternator you need.

Can I hook up two subs to a mono channel amp?


If the number you come up with is the same as what your alternator supplies, you need to take no action.
