SOURCE: will i damage the stereo in my 2001 toyota sienna

I=E/R Current = voltage divided by resistance.
4 ohms versus 8 ohms = higher current flow which will cause the amplifier (power transistor) to get hotter.

SOURCE: I am replacing the blown front door speakers in my

Actually the door speakers( less than 50W) do not need high wattage speakers as they are mainly powered from the head unit. Unless you are powering with a power amp a speaker of 300 watts is not required. But if the mountings are correct , the impedance of 4 ohms is correct, then it will fit OK and work. The only main issue will be the sensitivity issue of the speakers to work with a low output.
I have considered that a highly sensitive speaker( small voltage response) will sound great like an expensive power amplifier and high wattage speakers. Jensen had some good ranges in the 80's but now we have hard suspensions with poor response.
So my final suggestion is if powered from your head unit test it , there is no damage but if there is a response problem if you are a soft listener. Other wise there is nothing to worry on as the amp will handle except your listening pleasure.
So test to decide. Credit me if this info is helpful.

Speaker wiring diagram for a 08 dodge 2500 truck with 7 speaker infinity


Never have found good wiring diagrams for stereo's. Bought them and color codes didn't match. I have mitchell and alldata at work, they don't match. I wire them in with a volt/ohm meter. I find B+, Then hook ignition the the heater control wire. Ohm out the speakers. Thing is, you have infinity. You'll have to find the amp and cut the speaker wires and patch them there also, first. Just a note.. All speaker wires are twisted/paired wires. Cut the tape back 4 to 6 inches to find them. Another note. The speaker wires from the stereo to the amp will be a set of colors. From the amp to the speakers will be different colors.

Fisher amplifier CA 276 fan doesn't kickoff


Check to insure you have properly matched the ohm ratings of the amp with your speakers. If you are running an amp rated for 4 ohms and due to running speakers with a total ohm load of less than the amp will safely handle, it will overheat very quickly...and could eventually burn out. Study speaker ohm ratings on Google as set-ups with multiple speakers have to be calculated correctly when wirired " in a series" or "when wired in parrellel" which are two entirely different formulas. Good Luck

How to install aftermarket radio in 2009 mazda 6


The smartest thing is spend the money and purchase vechial adapter pigtail made specially for your brand of head unit and presided connector for a easy plug and play, from crutchfield.com. No guess work no schematics or wiring diagrams to follow plug in connector to vehicle harness and back of your aftermarket stereo put the couple plastic pieces of trim and your done. The support side of crutchfield.com is a very good resource. But if you don\'t want to spend the cash for pigtail, you can create account on auto zone.com and go to vehical repair guides and click locations. Why electrical schematics are in the tab labeled, locations, is beyond me. Print it and it will give you the speaker color codes and wire functions with connect pin location numbers. Just remember the industry standard, except for couple exotics, is that first color listed is the main color separated by a /, forward slash, and followed by the color of the strips. And japain cars occasionally use a stopped lines. Same color codes as if solid stripe. Auto zone also has the manufactures service procedure of how to properly remove old stereo unit with out damage. If your car is too new for auto zone listing then I suggest pay $20 to alldatadiy.com as a mechanic the shop pays $1500 a year subscription for alldatapro.com which has all the manufacture procedures, tsb\'s, schematis, and locations, but for twenty a year per vehicle you have access to all the same information as the mechanic in all non dealership associated shops.

When doing wiring always use soldering iron, pencil snapped, not a wiring gun. Gun gets too hot unless your building battery cables. Walmart got one for something like eleven bucks. And use double walled heatshring for 16-22gauge wire. Double wall has heat activated glue that makes water tight seal.any corrosion from water corrosion will be noticed as distortion or noise in stereo system. Are you installing amplifiers or subwoofers? For the pound chest felt thump? Are you using factory speakers? What wattage are speakers? And measure resistance with digital multimeter or use speaker impedence Value. Head units only produce up to a 4 volt constant variable frequency and current to transmit signal. The 50watts x 4 channel is not 50watts per speaker its true my 50 watts peak and 1/2of peak watts of RMS WATTS AT 25. AND DEVIDED BY FOUR SPEAKERS IS TRUELY SOMETHING LIKE 6.5WATTS OR SO. NO IM NOT GRABBING CALCULATOR, 6*4=24 SO A FUZZ OVER. I HAVE FOUR SIX BY NINES RUNNING OFF A 4 CHANNEL 600 WATT RMS 1200 WATT PEAK DUAL MONOBLOCK AMP RUNNING AT 4 OHMS PER SPEAKER WIRED IN PARALLELD EQUALS 2 OHMS OHMS PER BLOCK AND TOTAL OF 4 OHM TOTAL CIRCT LOAD OHM WITH ALL FOUR SPEAKERS USING BOTH BLOCKS. THE 600 WATTS IS RMS OR HALF OF PEAK AND WHILE USING DUAL MOMOBLOCK MEANS ONLY 300 WATTS PER EVERY 2 CHANNELS AT 2 OHMS. BUT IM WIRED AT FOUR OHMS AND OHMS LAW SAYS TO DOUBLE IMPEADANCE OR MEASURED CIRCUT RESISTANCE YOU NEED TO DEVIDE WATTS. SO 150 WATTS PER BLOCK. AND DEVIDE FOR TWO SPEAKERS AND GET 75 WATTS. SPEAKERS ARE RATED AT 90 WATTS, THANKS TO NEWEST 6X8 INCH, YA 8, 4WAY FULL RANGE SPEAKER. 4 WAY MEANS HAS FOUR SPEAKERS BUILT INTO ONE TO PRODUCE FOUR DIFFERECT FREQUENCY RANGES. STAY AWAY FROM COMPONET TYPE SPEAKERS AS YOU,LL HAVE TO MATCH IMPEDENCES, AND WIRE THE THREE OR FOUR SPEAKERS TOGETHER TO MAKE THE ONE FULL RANGE SPEAKER WITH CAPACITORS. AND ... ON AND ON. SO IF USING OEM OR ORIGIONAL MANUFACTIOR EQUIPTMENT, SPEAKERS YOU SHOULD NEED TO KNOW IF THEY ARE COMPONET OR FULL RANGE. AND NEWER CARS HAVE THE AMPLIFIER AND ALL THIS MATH MATCHED TO PROPER RATED SPEAKERS. AAN WELL AS A CFEW YEAR OLD VEHICAL MAY HAVE A 1200 DOLLOR KENWOOD IN IT WITH BUILT IN AMPLIFIERS THAT AFTERMARKET SYSTEMS DO NOT HAVE. BUT NO TAG SAYS THAT. IT\'LL SAY DELPHI FOR CHEVY MOPAR FOR CRYSTLER , MOTORCRAFT FOR FORD, AND SO ON. SO. HOW FAR DEEP DO YOU WANT TO DIVE? THE MONEY SPENT ON CONNECTOR ADPTING HARNESS FROM CRUTCHFIELD MAY HAVE JUST PAID FOR ITS SELF. IN STRESS AND ****** OFF TIME SPENT. AND THEY HAVE GOOD PRICES ON HEAD UNITS, SPEAKERS, DASH ADAPTER KIT, FOR PLASTIC SIZE AND MOUNTS FOR THE DIFFERENT SHAPED UNIT, AND GIVES A DISCOUNT IF YOU BUY THE UNIT AND ADAPTER HARNESS TOGETHER. WITH FREE SHIPPING A LOT OF THE TIME WITH AMAZING SUPPORT PAGE, CRUTCHFIELD IS THE PLACE TO GO FOR MOBILE AUDIO.

What system/subsystem are you asking about? Sound system speakers? If so, automotive speakers are usually 4 ohms unlike home stereo systems which are usually 8 ohms.

Do not use factory speakers with a aftermarket radio the ohm rating will not match and you will never get any kind of good volume out of them.
New aftermarket stereo's are set for 4 ohm load. consult ohms law when purchasing new speakers. ALWAYS run new speaker wire to your speakers. If problem still persists then you have to install a choke (noise suppressor) on the positive side wire of you stereo or relocate it to another source of power.
Resistor spark plugs never hurt as well.

that aftermarket radio may require different ohm speakers than whats in the car. open trunk and look at speaker magnets they will have the ohms printed on them if they dont say 4 or 8 ohms then they are incompatable with your stereo and may damage it if ohms are lower than 4 ohms. also make sure your radio balnce tone fader settings are correct. some of these new radios are so comlicated with that stuff it requires a 100 page book just to operate it.

My radio turns on but there is no sound. I just put in an aftermarket radio and it still has the same problem.


You can test the speakers with an ohm meter[should read either 4 ohms or 8 ohm].if they tes good then check the wireing to the speakers.

Will i damage the stereo in my 2001 toyota sienna if i replace the stock 8 ohm speakers with 4 ohm speakers? the rear speakers are blown. if i can should i do all four? i happen to have four 4 ohm speakers


You can use the 4 ohm speakers if you don't get carried away and crank the volume all the way up. If you really crank it up there is the chance of doing damage to the stereo amplifier. 8 ohm speakers would of course be better, but if it was me I'd probably try it. No guarentees though!

I just replaced my blown sub in my Avalon xls with a Kicker 07C84 and it works great. For the same price of a repair kit, you can just buy this new speaker.

All I did was splice the red and black wires within the factory plastic housing so I could still use the factory connector.
