If your amp can only handle an 8 ohm impedance, you can take 2 4 ohm subwoofers, connect them together in a series circuit, then you will have 8 ohm impedance. The magnetic effect falls off according to square law, not linear, so extremely close contact would be needed. It really works well, sounds good and all but the power isn't enough, you see my amplifier requires 12V 15A but the power supply only gives 12V 7A. Is there not an easy way to do this? Well, thanks for all the insights. Wonder what amp you had in the car for it if the home audio amps Cheap brand is expensive.
The backside of the wall is the inside of a closet, so the unit can poke through the other side and be wired from there. For home theater usage you usually want lower extension, are going to get less room gain than what you would get in a car, and space is less of an issue. With a bit of setup they sound as good as the Paradigm and alpine and have respectable output. I'm sure this is dumb, but someone tell me why. You need a 12V power cord to use your car stereo power supply for home use, but you can easily get that from a hardware store.
Do you know anything about this? Other subwoofers have two voice coils and will have four tabs where wires are connected. As long as your computer power supply has enough power you should be good. As long as your amp can handle the 4 ohm impedance, it will work. Try to use multiple 12 volt wires from the power supply so each wire carries a lower load and if it is multi rail, try to get them from different rails normally indicated with stripes so yellow yellow with a green strip for instance. By the way, I'm pretty sure the sub is 4 ohm, if that's at all important. Speakers This is especially true of speakers since they are passive devices.
The typical car speaker is four ohms and most home receivers are designed for eight ohms. Notice that without the gain from the car the subwoofer performs pretty poorly in a small 1. The other thing I seem to remember is that I needed a small amp I still have the small amp I bought at Radio Shack to take the line-out from the car stereo and then connect to some speakers. There are some modifications that will need to be made as there are some very basic differences between the designs of car and home subwoofers. Maybe thats too simple or maybe I am.
Umm, how safe would be wiring up my old car amp to 120v be with a 12v inverter? I am confused with why you would bother with this since for the same money you can get something that will function similarly and not have the power issue. Keep in mind that rooms in the home, especially large ones, will not have the same effect as a car. If you've been lucky enough to get it working then post pics, links and whatever else to show your handy work off. Here are the colours and the channels. I suppose it's probably not worth it unless I can find a receiver specifically rated for that 4 ohm load, preferably with a built-in crossover. Subwoofers Like other speakers, subwoofers built for the car environment should work well in the home environment.
You may freely link to this site, and use it for non-commercial use subject to our. Step 5 - Wire the Subwoofer to the Amplifier If the speaker has two wires only, you will need to connect the positive wire from the speaker to the positive terminal on one channel of the amplifier and the negative wire to the negative terminal to the other channel. Your left and right positive to your positive cable, your left and right negative to the negative cable. Thanks for reading, and happy listening. But I do feel sorry for the neighbours. Unless you want the bass to overpower the rest of the music in your car, choose a cheap amp that is rated about half in terms of wattage output of your main car amplifier.
You connect the speakers to your car stereo using the gray and green wires. Consider Alternatives Playing around with wiring can be dangerous, so if you're interested in setting up a car stereo power supply for home use, first ask yourself if things could be done another way. If you want to use a car battery for a temporary arrangement, the battery will serve as its own power source. The next step is to connect the yellow and red wires on the stereo and add an additional speaker for stereo sound. I'd love to hook it up to a good receiver for my computer audio, but I'm just not sure if that's a good idea.
We welcome your comments and suggestions. This is optional but it helps to create a self-contained unit. I can say absolutely because I did the exact same thing in my guest bathroom anyone for mixing electricity with water. If you have a 12 volt power supply for it assuming it is active , I see no reason you can not use one. Liandi has traveled extensively in Europe and East Asia and incorporates her experiences into her articles. You could purchase an inverted one, but those are a temporary solution at best. I personally use my laptop as a source a lot so this works best for me.
