Unless you want to listen to music with your engine off, adding a dedicated car audio battery isn’t going to do you any good—and it may actually hurt. That might seem counterintuitive, but the reasoning is simple. The battery in your car is there to serve one purpose: to provide enough amperage to start the engine.
Secondary batteries are necessary when running the car stereo for extended periods of time. They are also a necessary addition for systems with such a large power draw, and systems where the electrical needs exceed the output of the alternator.
AGM batteries are the Car Audio Battery of choice for those that choose to add additional batteries to their system. Because of AGM’s low internal resistance, fast recharge and they are sealed and maintenance free, they work best for this application.
Will a regular car battery work for car audio? – Related Questions
How many batteries do I need for 3000 watt amp?
For example, the average car battery has a 50Ah rating. If the battery banks you want to purchase are also 50Ah, you will need six of them for a 3000-watt inverter. If your batteries are rated 100Ah, you would only need three, and with 170Ah rated batteries, only two would be required.
How many batteries do I need for 5000 watt amp?
You will need at least one 450-500 12V battery or two 210 12V batteries to supply 5000 watts of power for 30-45 minutes. If you’d like an hour of 5000 water of power, you’ll need a 750ah 12V battery.
Are AGM batteries good for stereo systems?
This heavy-duty 12-volt battery can power almost any sound system around with a whopping 1,800 watts of juice. Advanced AGM technology gives this battery a long lifespan. Because it’s AGM, this battery can be mounted in any position in your vehicle.
Can I use a marine battery for car audio?
You also need to take a look at the fact that cars do not really need a lot of deep cycle power from marine batteries. Cars use starter batteries because these are the batteries that they are most equipped to use. Marine batteries are probably not recommended to power cars for a long period of time.
Deep cycle/Marine batteries will work OK, but are designed more for constant sustained low-power draw.
What size battery do I need for a 2000 watt amp?
The easiest rule of thumb to follow with electrical upgrades is that for every 2000 watts of RMS power you add, you’ll want to add 100aH (amp hours) of AGM battery.
Does an amp drain your car battery?
If the amperage needed is more than what your alternator can produce, you can confirm that the amplifier is the reason behind your dead batteries. Fortunately or unfortunately, amp draining car battery when off is also a real possibility no matter how good the alternator is.
What size alternator do I need for 3000 watt amp?
3000 watts / 12V = 250A. You’d need a 250A alternator to keep up with it.
How many amps does a 1200 watt car amplifier draw?
100.0 Amps
Should amp wattage be higher than Speaker?
Should Speaker Wattage Be Higher Than Amp Wattage? No, It is always recommended to use approximately twice as much amplifier power as the speaker’s power rating. More watts may provide more bass, but only if the amplifier you’re currently using is insufficiently strong for the speakers you’re using.
What if my amp is more powerful than my speakers?
Amplifiers can be too powerful for speakers. Speakers are limited by the electrical energy that they can convert into audio. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely.
RMS power handling of a 55 series 12” dual 2 ohm voice coil subwoofer is 400 watts. Two of these subwoofers would mean you need 800 watts of power at to the total circuit impedance.
Can subwoofers damage your alternator?
Is it possible to harm your alternator by using subwoofers? Subwoofers don’t have the ability to damage your alternator on their own. However, if a sub and its amplifier draw too much power from your battery, they can cause harm to your alternator. This might lead to overheat and can potentially destroy the alternator.
How do I make my subs hit the hardest?
You can also make minor upgrades to your subwoofer to make it hit harder. Change the small cone in front of the subwoofer, change the voice coil or get a new enclosure for the subwoofer. If you don’t want to put much effort into it, just turn the volume to zero and play your track with medium bass.
What’s the hardest hitting subwoofer?
The hardest hitting subs would be the Rockford Rockford Fosgate Punch P3D4-10 10″ 1000 Watt Peak / 500 Watt RMS Dual 4 Ohm Car Subwoofer with Anodized Aluminum Cone and KICKER 44CWCS124 CompC 12 Inch competition 600 Watt 4 Ohm Single Voice Coil Car Audio Subwoofers with Polypropylene Cone and Polyurethane Surround.
Does a bigger box make subs louder?
Too large a box allows the driver to exceed its’ mechanical limitations. Regardless if you believe it sounds “louder” or “better” it’s just not wise to do so. Buy a bigger sub. a bigger box makes it louder at a note just above the tunning hz.
