Question about AAD E-30 Main / Stereo Speaker

Stereo speaker problem

I have a 4 speakers system. One speaker shuts the receiver off when I power it up. I've isolated it to one speaker by disconnecting all speakers and trying one at a time. I then swapped the wires for this speaker from red to black terminal and this had no effect. It still turns the receiver off. Do you have any suggestions?
Thanks,
Barry

The speaker is bad. The receiver detects a shorted condition and shuts off to prevent the amp section from damage. Replace the speaker or the wires. Something is shorted.

Can I replace the speakers on this system? Speakers are too large for space & want to replace with another brand.


make sure impedance is the same so 6 ohms and the power rating of speakers is no less than 200 watts peak rms.And bare wire ports on back of speaker.
The power rating is so the speakers can handle the maximum power delivered by stereo amplifier without burning out speakers coils.

The two rear speakers in my car have no volume


The first question I have to ask is: Are they automotive speakers? Home stereo speakers are typically 8-ohm impedance whereas automotive speakers are typically 4-ohm. If you try to put home speakers in a car, your car stereo head unit may not may not have the power required to overcome the higher impedance. If that's not the case, check your wiring to the speakers (I assume this is an aftermarket system?). If there is nothing apparently wrong with the wiring, try connecting a couple of known good speakers to the wires. If they work, your existing speakers are bad. If they don't work, you probably have something wrong with your stereo head unit. Good luck.

I've got a kr-a4020 am/fm receiver and I'm going to hook some speakers up to it to put it in an outside entertainment area but I don't know the max wattage speakers to get that the system will...


Hi!

When connecting some speakers to an amplifier the first important thing is the impedance. This is in your receiver 4 ohm for each speaker (the impedance is written on the back pannel of your receiver). Using a lower impedance for the speaker can and will harm the receiver.
The second important thing is to use speakers with a rated power no LESS then the receivers rated output power. In your case it means no LESS than 100 W. Using speakers with a higher rated power does not any harm to the receiver, it means only that the speakers are able to handle the power delivered by the receiver or even more without any danger to get the magnetic coils inside the speakers burned.

I have 4 wires, red (power(, black (ground), green (speaker), gray speaker...the stereo has these same color wires...so I connect the corresponding color. The boat has NO yellow battery wire that is on the...


(http://inform3.kenwoodusa.com/manuals%5CKTSMP400MR.pdf )
Here's a link to manual and wiring on page 30 on the PDF file.
Yellow is constant power from battery, for memory etc. Red should be to switched source.If need be, you can connect both to battery, but remember, you'll have constant power draw on battery when stereo left on but switch turned off, and will draw battery down, if you forget to shut it off, and leave the boat. Speaker negatives to black should work but I would advise hooking my 2 right and 2 left + speaker wires from stereo together, then to one of the speaker positives,right or left for better sound. Fronts will usually supply higher ( high and mid range), and rears will supply lower sounds (woofer) Joining them together will give better sound usually, when only using 2 speakers, on a 4 speaker stereo. You may want to test with them joined and not, to see what sound you like better.

What do you mean by the subs should have more watts than the amp.and subs mean woofer ? actually i dont know any thing abt this. what is 8 ohm stereo, 8 ohm bridged,4 ohm stereo. etc etc...?


If your planning on using a stereo system in your car or home you need to follow some rules otherwise your just wasting money. The watts of a speaker means how much power it can handle. The higher the number the more power it can handle, and usually the louder it can get without distorting. If your amp has more power or close to the wattage rating of the speaker you will blow the speaker, it can even get so hot it ignites. The amount of ohms is the electrical resistance the speaker provides. House speakers usually have 8 ohms where car speakers tend to use 4. 8 ohm stereo means your left and your right are separate channels and each speaker has 8 ohms. 8 ohms bridged means you bridge the left and right channel to increase the power output of the amp and you have to use either 1 8 ohm speaker, or 2 4ohm speakers in parallel to prevent damage to the system. Same goes for 4 ohms. If I remember correctly you want your sub(woofer) to have a wattage rating 20% higher than the amp. Remember if the speaker overheats its no good, but most amps if they overheat they just shut off until they cool off, but only if they state they have a thermal overload protection.

Sansui 3200Z stereo receiver -- Both A and B no longer drive speakers. Progressive failure: first Right went out, now left.


now you have to try and isolate frist your problem .is it your speakers? your cabling or your receiver? check all your cables for any loose connections. check your speakers for possible damage, you can try using another set of speakers to your receiver and see if it does the same thjing and wont work. or try also your speakers in another set of receiver.

The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Your Pioneer unit has an internal overload protection system to prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized HK service center must do this.] But, before you take it in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!
