At each pair of speaker wires or near the speaker wire connector, strip off about 1/2″ of insulation and tap off it. To do so, either wrap wire or cut the factory wire and connect to it using crimp connectors while attaching a small gauge wire when doing so. A car powered subwoofer is one that is an all-in-one bass system made up of a special enclosure, matching subwoofer, and has an amplifier already built-in. Installing a subwoofer in your car is often hard work depending on the vehicle and what you’ll need to go through for installing and hiding the wire. If you’re adding a subwoofer to a factory system you should definitely prepare for extra work.
If you don’t see an opening, you may be able to make a hole with a sharp knife or drill fitted with a steel bit. Pick a stable, well-ventilated spot for the subwoofers. Your sound system will produce a lot of heat, so additional space around the subwoofer helps it perform better and last longer. Many people choose to put subwoofers in the trunk since it is an open and accessible area.
Benefits of Installing a Home Theater Subwoofer in Your Car
Reasons for this are that class AB has better sound characteristics. There is a lot of discussion about this so i'm not gonna go there, but main difference between them is power consumption. While class D has excellent efficiency of +80%, class AB might be only about 50-60% which means they will also heat up alot more. This is thing to consider when choosing PSU and desired output power. Run the remote and RCA wires from the trunk to the stereo head.
The best kits include installation accessories like ring terminals, zip ties, and sometimes wiring grommets. I have explained each step of using a car subwoofer to the home theater in detail so that there remains no confusion. Though it is possible to connect a car subwoofer to the home theater sound system, it is not always the best idea. If you have the option of using a home theater subwoofer, please do that for the best experience. So the first task is to convert the power with a power inverter.
Buy a Power Inverter that turns the home 110 Volts into 12 Volt
Note that while option #4 is the easiest of all, I don’t recommend it because you’ll lose 1/2 or more of the stereo’s power output. That’s because the power isdivided between it and the sub. The wires can be connected to the brackets beneath the terminals on the appliances. Keep in mind that the red wires must be twisted with red wires and the dark wires must be twisted with dark wires. If the subwoofer features spring clips, use the speaker output of the receiver to hook it all up.
Now the power is converted, you can proceed to amplify the power. Decide the gauge number according to the subwoofer you are using. The manual of the subwoofer would have the instructions. Yes, quite a lot of materials are needed to accomplish this project. It must be better to have a home theater subwoofer rather than having a car subwoofer considering the materials are labor needed.
How Much Does It Cost To Use A Car Subwoofer To Home Theater?
Hook your audio source to amplifier, play test tone and turn the volume up. This should be done while your speakers are hooked up and using few test tones. Since your speaker has impedance which varies by frequency you are playing it at, its always best to play different tones to see if amplifier distorts. These wires will connect the car subwoofer to the car amplifier. Make sure to match the input color to the color of the wire. I mean, plugin the red wire into the red terminal and black wire into the black terminal.
This one’s easy to answer, although it’s important to be clear about power & amplifiers.In general terms, no, a sub won’t work ok without an amp. You can connect them just like you would a speaker, either to unused speaker outputs or also connect them alongside speakers already in use. Example of an 8-Ohm compatible low-pass speaker crossover for blocking all sounds above a low bass frequency . These are used to get “clean” sounding bass from a subwoofer when there’s no crossover already provided. The quick answer is thatit depends.There are several basic things you need to understand first before you try.
Setting this up requires connecting the LFE or subwoofer output jack on the receiver/amplifier to the LINE IN or LFE IN jack on the subwoofer. It's usually just one cable with single RCA connectors on both ends. After amplifying the car power, you have to work on the home theater. Use stereo cables to connect the car subwoofer to the amplifier of the home theater sound system. One side of the cable will go inside the input plug of the subwoofer.
If possible, push a hole through a firewall wiring harness seal (“grommet”) and push the amp wire through that. You can then find the edge of the carpet which is usually easy to pull back and tuck wire into. I saw this many times, and it’s incredibly disappointing to see. For noticeably louder and better subwoofers, however, it’s best to buy the largest you can that will fit in the space you have. Regarding power, you can likely get by with less if using a small subwoofer (for example an 8″ or another small type of subwoofer in a premade enclosure). A low-pass crossover is a feature that will filter out upper-range sounds and will allow you to play only clean sounding bass.
Use wire strippers in case you need to cut the ends of the wires. To set up a car subwoofer to your home stereo, you must first purchase an RCA cable with the red and white ends. Next, you have to connect it from your car’s subwoofer output to the input of your home amplifier using the red and white cables. Amplifier wiring kits come in different price ranges and quality levels. Some only contain a fuse holder, fuse, power wire, ground wire, and the remote lead wire .
Battery is just another source of direct current, just like ATX power supply. I don't understand "This amp seems to work only when it is connected to a real battery". Amp doesn't care where is the power coming from as long as it's 12V DC (10-14VDC). Some speakers can handle more power than rated without getting damaged, some may not. To ensure you are not getting more power to them, use nominal impedance rating and ohms law to determine how high should voltage on output be. PC ATX and Server power supplies offer a lot of power and they can be cheaper than other solutions.
Connect this to your remote on wire included with your kit. Use the ring terminal to fasten to a battery clamp bolt or stud. Use sandpaper or a wire brush to remove corrosion and expose clean metal if necessary. Some models, however, feature larger speakers and high power built-in. I’ve covered this topic and show some great examples here. Ported speaker boxes generally have slightly less “tight” sound but can often play louder and deeper vs. a sealed box for the same amount of power.
Setting gains isn't that hard if you have SMD DD-1 or oscilloscope. Turn every filter, bass boost and gain down and turn bass knob or volume knob all the way up and leave your audio source at about 50%. Get 40Hz test tone for subwoofer amplifier, or 1kHz for full-range amplifier. Its safest to tune it at 0dB since that way you can't clip output signal even if you listen to rebassed or bass boosted music. If you dont listen to those types you can get -3dB or -6dB but you might clip it with some music.
Use a test meter when possible for troubleshooting amplifier problems. Use pan-head screws and not self-tapping screws when you’re mounting items to wood or wood-like materials. Car stereo installation straps are fantastic for custom mounting amplifiers, amplifier boards, and subwoofer boxes to a car. On most aftermarket car stereos a blue output wire is for switching an external amp on and off.
