how do you do it?

Question

i bought an ma audio amp that it supose to throw 7000 watt rms but it says that i have to give it 17 volts how do you do it

for the ones that dont believe in the amp here is the web site

Answer 1

u have a high volt d class amp it will run at 12 or more up to 17 at 17 volts it will put out max power if u go to a auto parts store and get 3 6 volt batts wire them in + to - u will get about 18 volts but do not hook them up to your cars batt just to the amp it self u can charge the batts with a battery charger or run a power inverter to power a battery chager that u put in your car the amp is really a comp amp only its not really made to use in a street car

Answer 2

An HO alternator won't give 17 volts...the cars electrical system won't tolerate more than 16 volts anyway.

The difference between a 14.4 volt feed and 17 volts won't even be noticeable. It takes double the power to get just a 3dB gain in volume. The wattage may drop to something like 6000 watts RMS which is not even a 1 dB difference.

Besides....

If your total system power is 1000 watts RMS or more, you will need to:

1. Upgrade the alternator to a high output alternator
2. Upgrade to a heavy duty deep cycle battery
3. Upgrade the "Big 3" - that is to replace the power wire between the battery and alternator, the ground from the battery to the chassis and the ground strap from the engine/tranny to the chassis with at least 0/0 AWG wire.

Failure to do this will result in you replacing them anyway as the alternator will eventually fail.

Here is a guide that will calculate what size alternator and power wires you need http://www.datafilehost.com/download.php?file=6d26c621

A second battery is never a good idea as it's an added strain on the alternator to charge two batteries AND supply power for the car. The ONLY time a second battery is useful is if the audio system is to be used with the car off.

A cap is only good so far as the audio system isn't trying to pull too much from the electrical system. A cap doesn't provide more power, it's designed to 'stiffen' the voltage to the amp, nothing esle. If the current isn't there, a cap won't help. The alternator must have at least 20% more amperage power than the entire vehicle and sound system combined for a cap to be of benefit which is ironically the same requirements for an amp to be efficient.

R1volta,

Do you even have a clue as to what it would cost (if it existed) for a DC to DC converter to push 7000 watts RMS!?!?!

That's over 380 amperes! The service running to your house is only 200 amp!!!

If you don't know, don't answer.

Answer 3

Running an amp just over 1000 watts requires many upgrades to your cars electrical system. Never mind 7000 watts. What are you going to do with 7000 watts? Do you even know what a watt is?

Answer 4

7000 watts RMs is going to take serious alterations to your vehical, and the 17 volt thing, likely a gimik to make it look like your getting more than you are, anotherwords, find the rating for 14.4 volts, thats the reall wattage, and trust me that is still plenty. as said before anything over 1000 requires new alternators, new battery, big three upgrades, ect. and for that amp your talking multiple alternators, and a serious rats nest of wiring.

Answer 5

to get 17 volts you would need to upgrade your alternator to a HO (high output) alternator

Answer 6

Buy a dc to dc converter. Many are available with adjustable outputs.

Answer 7

that amp is in no way, shape, or form 7000rms.
