Receiver is designed for 8ohm speakers. you can't use car audio speakers. they are 4ohm. Most receivers will tolerate 6ohms but not 4. This will short the mains and destroy your power amp!

They were bought off the back of the truck but great speakers.One of my Vega LS 15 blew a woofer. The 10s are 600W- 2ohms. I hooked them to a H Kardon 3470-100W 8 ohms.Will that damage anything?


In a word, YES! The HK is designed for a minimum 4 ohm load. You can wire (2) 2 ohm speakers IN SERIES to get a 4 ohm load. Do NOT run one of them at 2 ohms as it will overload and damage your amp. Too nice an amp to abuse it like that...

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).

I want to hook two speakers on each terminal (L/R).


The correct way would be to hook only one speaker to the powered outputs and use PRE-OUT outputs to connect separate amplifier (or active speakers).

For 2 speakers to work connected to the same powered output of receiver, their impedance would need to be high enough. Yamaha receivers officially support impedance >= 4 ohm for front speakers. If you would connect 2 different 8 ohm speakers, the combined impedance could be theoreticcaly 4 ohm, but that depends on many parameters. On low volumes it should work, but could overload the receiver if used for louder volumes.

Also note that the impedance is a function of frequency (specific to every speaker), so for different frequencies the power from receiver would be devided differently between the speakers and the sound would not be good.

When i turn my two 12" kicker l7 up they cut out


You could be having an amp overload condition. Make sure your speaker impedance matches the amp specification. Esp if you have bridged the Amp the impedance should be at least 4 Ohms and not below. When you connect two 4 Ohms speaker in parallel the total impedance becomes 2 Ohms !!!.

Hooked the damn thing up power my subs wonderfully for that evening, and all day today, got in this evening and nothing, checked the amp and red light, ok, fine, checked the manual, says the light protects...


probably something corssed in your speaker wiring. be sure that you did not exceed the ohmage capabilities of the amp, and that no speaker wires are crossed, or shorting out on the frame. if you have too many speakers hooked up, that can reduce the ohmage, and your not supposed to go below 2 ohms -per channel, or 4 ohms bridged mono.

I hooked up my xd1225 cd player in my car and it gets SUPER hot/overheats. What did I do wrong?


your speakers are of an incorrect ohmage, or you have too many speakers hooked up to it. your stereo likely calls fo a singler 4 ohm (4?) speaker per channel and the factory speakers may be lower than 4 ohms, or you have several speakers hooked up to the same channel. there should be 4 channels, each with no less than a 4 ohm (4? ) load. two 4 ohm speakers wired to the same channel in parallel (both attached to the amp's poositive/negative leads) will create a 2 ohm (2?) load, and overheat the amp. if the 2 speakers are a woofer/tweeter combination, and there is a capacitor involved, it may be ok, but 2 woofers, or a woofer and a subwoofer hooked to the same channel will likely reduce the ohmage below 4 ohms (4?). look at the back of each woofer speaker, and look for an ohmage rating stamped to the back of the speaker magnet to verify that they are 4 ohm (4?) speakers, and verify that only a single 4 ohm speaker is hooked to each channel. the car likely has multiple speakers hooled up to each channel, which would lower the ohmage rating below 4 ohms (4?).

I had these 12in pioneer subs so I went and bought the new Rockford Fosgate they came out like a week ago my problem is every time i hook them up to the amp the protection red light turns on can you...


if the amps impedance is higher than the speaker, it will trigger the protection circuits, because the amp sees it as an overload, example the amp has 8 ohm impedance specified, and your speaker has 4 ohm specification, that is a clear overload. Bring the subs back to the amp's dealer and have the amp replaced; the one that matches your subs. Hope this helps... ;-)

Can i hook up my sub if it's wired to a 2 ohm and my amp is 4 ohm


Hi martineztag
You should never connect a load of an impedance less than the min the amp is able to drive. This can have disastrous consequences that may easily result in failure of the amps output stages. You need to use a different configuration that does not overload the amp in this manner for safe operation.

VSX-D608 Overload and shutdown


Overload is displayed when the amp draw is excessive, and can be caused by different faults.
when Overload is detected, the protection circuit will shut down the unit to prevent further damage.

The first thing to try is hard reset. Shut down the unit for about one hour to drain power completely.
This can fix minor problems that can cause overload, for example electrostatic charge accumulation on internal capacitors.

If that does not fix the problem, then you must find the fault.

Overload can be caused by shorted speakers, wrong impedance speakers, or by a contact on speakers wiring.
Check speakers connection and test different speakers with 6, or better 8 Ohms impedance.

Another test can be done by unplugging all speakers, and reconnecting and testing them one at a time, at a very low volume.
No more than two 4 Ohms speakers can be connected to the unit, or you will get overload.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

POWER ON PROBLEM


Well, I know that u will overload it if u use any 4 ohm speakers on it. And a LOT of center channel speakers are 4 ohms. Also, it has problem working with 5.1 (optical or coaxial). If that is the case, try to run it on stereo...
