How do I use my car speakers with my home system?

Is it possible to place a tweeter from a home stereo speaker in a car?

  • I realize home speakers have an impeadance of 8 ohms and car speakers are usually 4 ohms. I was just curious if it would work; because I have some Yamaha home speakers that have busted cabinets. I have a nice home theater system and have no home use for these speakers but I could really use some high end in my car. These speakers of course have built in crossovers in each cabinet. Any advice would be helpful, except "go buy some 4 ohm tweeters", I am in nursing school so money is too tight for that. Thanks.

    Keep in mind that you're adding load to your head unit which may cause it to get hotter.... http://spkrbox1.spaces.msn.com/ for real "sound" advice. Your system won't mean squat without a well designed box to put your subs in. Some manufacturers have recommendations as to dimensions of various types of boxes. It is best to find someone who builds boxes if you go with something other than a sealed box. You should always match up RMS (Root Mean Square) watts of Subs and amp per channel as well as impedance's(resistances). When a sub has rating of 600 Watts MAX it really has an RMS rating of about 200 Watts RMS. RMS is the nominal wattage your most likely going to get out of it. Remember, a 200 Watts RMS amplifier has more power output than a 200 Watt MAX. If your amp is rated at 4Ω don't subject it to 2Ω, it will fry. Here is the formula for subs in parallel: Z = 1 / (1/sub1 + 1/sub2 + 1/sub3 + ....) For series, just add them up (sub1 + sub2 + ...). You can mix and match these equations to get the right impedance required by your amp. Example 1: Amp is 2 channel and rated at 4Ω, 4 subs @ 4Ω each. If I connect two in parallel and the other two in parallel and connect the two pairs in series, I would have a total impedance(resistance) of 4Ω. So to the amp, it's just one sub. Example 2: Amp is rated at 1Ω mono, 2 subs @ 4Ω each dual voice coil. If I connect two voice coils in parallel and the other two voice coils in series and connect the two subs in parallel, I would have a total impedance of 1.6Ω. Which would be perfect for a 1Ω stable mono amp. You should use a capacitor as well. Recommend for every 500 watts MAX you use a .5 Farad cap Example: 1000 watts MAX - 1 Farad cap You will also need what's called a "line level converter" if your stock head unit doesn't have RCA outputs or your amp doesn't have high-level inputs.

If you like I can send you some plans for reference. My plans are for a 4-th order band-pass bass box (A.K.A. bass-reflex) that holds two 12's. Also included are java calculators you can use to figure parallel and series values given Ω values, tips on box building and types, calculating port diameter and length(if used), calculating box dimensions for types of boxes (sealed, wedge, cylindrical, etc.), materials needed and even how to make a jig for cutting perfect holes for your subs. Just e-mail me [email protected] My system Blaupunkt TSw1200 subs with a Sony Xplōd XM2200GTX. My amp is 1200 watts (200 Watts RMS X 2), subs are 600 watts (200 Watts RMS) each, cap is 1.5 Farad SPL is about 112 db each sub Total cost(so far) = $410

Hi. I have used house speaker's several time's and to me they sound better than car speaker's. they will handle the power. i have ran two 12 inch house speaker's and the cabnet's. I ran a 500 watt car amp brigded over and they worked really good with no problem's....just make sure that you hook them up right.

As long as the tweeters are either 4 or 8 ohm, you would have no problem running them in your vehicle. If they are 8 ohm, you could even wire two of them in parallel and run them mono. Either way you install them (stereo or mono) you should be happy with the sound. Now, this is assuming they have their own dedicated channel from the radio / amplifier. If you plan on wiring them with speakers that are already installed in the vehicle, and the tweeters are 8 ohm, you may need to wire each tweeter in parallel with the existing speakers to obtain a 6 ohm load. You would not be able to run them mono.

Ohms arn't the only thing workin against you, car speakers are built different than regular home speakers, they are designed to resist the elements, and take the streeses that come from being inside a car. As far as, is it possible, for somthing that you're probably going to throw away otherwise, go for it. You'll never know if ya don't try!
