Depends on the make model and wattage of the speakers.

Yes you can,,,,,BUT the output labelling on the AMP will tell you where you can connect the 4ohms or the 8ohms....please read these labels and connect the 4ohm speakers to the 4ohm terminals, and the 8ohms to the 8ohms terminals...

If you intend to connect the 4ohm and the 8ohm speakers in parallel then the output impedance terminals you use should be the 4ohm ones.

If there is no labelling showing any 4ohm output terminals then its best if you dont use the 4ohm speakers at all....just connect the 8ohm to the 8ohm terminals...you dont mention any crossover networks inside the speaker boxes or if you have tweeter speakers... so just stick to the basics above at present....

SOURCE: 6 ohm speakers - 8 ohm amp

This is a tough one due to the info at hand, but I'll take a stab at it.
I'll assume that your amp is not a tube-type amp. I'll also assume it is a relatively recent "solid state" design. If those assumptions are correct, connecting a 6 ohm load to an 8 ohm amp should not cause significant overheating or amplifier instability.

Hum is probably due to insufficent grounding somewhere. Make sure coax cables at input are good. Re-locate unit away from aplliances

SOURCE: 3 8 ohm speakers 1 stereo amp 2channel a 1 channel b will this do dammage

If you only have 3 (8 Ohm) Speakers and want to hook them all up, you will need to balance the impedance of the sides or you will be too loud on one side and not loud enough on the other. This will cause your amp to work harder on one side. (Not Good)
I did not see the speaker A and B in the instruction manual.

Because of that, I will state the following.
I would not recommend that you hook up anything that is unbalanced. I would use just a pair in two channel mode (This would give you an 8 Ohm load on each output). The manufacture recommends a 4 Ohm load for the best output of this amp. But the most important thing to remember is that your speakers must be able to handle this much power or the speakers will be permanently damaged.
This amp has Protection to cover: Full short circuits, Open Circuits, Thermal and HF protection, and stable into reactive or mismatched loads.

You could hook up all three speakers and the amp will work, but, I would not recommend that type of hook-up.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Want to use my current speakers with a new surround sound system. Current system is 5.1 channels, rated at 100w per channel @ 8. Ohms. New System is rated 145watts, 5.2 channels at 6 Ohms. Will b ok?


Hi Ronald.
8 Ohm speakers will work just fine as replacements for the
6 ohm speakers. When fitting speakers you need to consider
The power handling capability. The impedance and the frequencies
involved. Power handling is expressed in wattage ie 100W.
Unfortunately this can be expressed in rms, max or peak music. The rms value (root mean square) is the only really relevant figure as this is the continuose handling power at 1 KHz. The impedance
is the resistance that the amp sees but is not a dc resistance and
varies with frequency. The lower the impedance the more power
will be drawn from the amp. In the event of a short circuit across
the speaker the amp will try to deliver infinite power into an infinitly
small load in an infinitesimal amount of time and will self destruct.
Using an 8 Ohm speaker draws less power than a 6 Ohm speaker.
Connecting speakers in parallel; results in the impedance beingreduced. For example two 8 Ohm speakers in parallel will result
in a 4 Ohm impedance load but in series will be 16 Ohms.
Incidentally the the .1 (5.1) is the sub woofer which only has
to handle the bass frequencies, a small percentage of the
amplifiers overall frequency response..
Connect your speakers and then power up the amp last
after double checking there are no shorts on the speaker
cables.
All the very best from Vintie.

Can i hook this amp to my home sound system


Technically, yes, but there are some challenges. First, the input voltage to the amp is 12VDC, not 120VAC. You would need to find a power supply large enough to supply 12VDC at 30-40 amps (plus has proper currently limiting or fuses to protect against overloading). Second, most home speakers are 8 ohm impedance. While the amp can power an 8 ohm speaker, the output power is cut in half (compared to a 4 ohm speaker).

Wiring a crossfire vr602 at 4ohm


OK what you are saying now is that your speakers are dual voice coil; models? 4 Ohms per Coil? I have always used single 4 Ohm Voice ciol speakers since amps are mostly based on 4 Ohm outputs. but you can get 8 Ohm dual voice coil subs also. With 8 Ohms per coil you can get 4 Ohms if you parallel the wires. What is best for you and will get you the most stable power and still will be in the specs of that amp is to run the amp in BRIDGED MODE running each subs voice coils in series with each other then run those 2 subs in parallel to the amplifier giving it a 4 Ohm load. So, your will have two sets of wires from your amp 1 for each speaker. Then you will take a short piece of wire that will connect the + to the - of each voice coil then hook up the wires from your amp to each sub What it will be is 4 Ohms + 4 Ohms = 8 Ohms per speaker the 8 Ohms in parallel each speaker to the Bridged amp output using just the + from one channel and the - from the other will give you a total of 4 ohms and power out put of 600 Watts so that ends up being 150 watts per voice coil or 300 watts each speaker

usually combo amps are 8 ohm for guitar. a 16 ohm speaker load comes into play usually on half stack set ups. danville tec 10d, i would guess a ten inch speaker, which is also very common for guitar amps.

I need to know the ohm rating for the speaker in a


Judging from the "10D", that most likely means 10 watts. 6.5 inch speaker, probably 8 ohms. Most amps of this nature have 8-Ohm speakers.

Their 12-watt and 15 watt amp have a 6.5". Their 20 watt amp has an 8". The 80 watt has a 12".

Hope this helps.

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.

SHOULD I GO AHEAD AND BUY A 400 WATT AMP?


All amps aren't created equal. More exspense amps put out "cleaner" power. You need to know what the RMS power rating is for the amp at 8 ohms and 4 ohms. Also, is the speaker an 8 or 4 ohm speaker? How you wire a speaker or speakers (series or paralell) can change the ohms (resistence) which will change the power put out of the amp. Also, I'm assuming you are setting it up in mono?

If you had 4 single voice coil speakers you can create either of those 2 ohm or 4 ohm setups. If you run 2 of them in parallel you will get the 4 ohms. If you run 4 of them in parallel you will get the 2 ohms. In parallel I mean that you connect the positives together and run them to the positive on the amp and the connect the negatives together and run them to the negative on the amp. Let me know if you need more help. Good Luck.

Car Audio System Drwing too much power with 2 different Amps


A dual voice coil speaker can be wired to be a 2 ohm speaker or an 8 ohm speaker depending on whether you wire it in series (8 ohm) or parallel (2 ohm). When you bridge your amp then the two channels will share the load from your speaker. If the speaker is wired as 8 ohm then each channel of the amp is driving a 4 ohm load which is fine. If you are bridged into a 2 ohm speaker then each channel will be driving a 1 ohm load, which is a very very heavy load. Is your amp designed to drive a 1 ohm load? If not then that would explain why you are having a problem.
