Doubtful - the factory head unit isn't meant for 2-ohm operation and will stand a chance of damage.

    If you're going to run 2-ohm speakers, you need to make sure it's spelled out on the package of the head unit that it's 2-ohm stable. If it isn't explicity stated, assume it's not and don't use it. A better bet would be to run the speakers off a 2-ohm stable amplifier (those are common, whereas 2-ohm headunits are rare, if they exist at all - I've never seen one). That way you'll be able to use the speakers you have and with an amp, you'll drive them much more cleanly than you will off a head unit.

I'm looking for an amp for four 6x9" kickers CS. Can you help me? Thanks


What is the power rating of each speaker? The impedance figure and how you intend to connect them are needed to correctly specify an amplifier

I have a total of ten speakers in my van and i want to know the best way to connect these speakers to my after market cd player they are all regular speakers not subs


I would pick the 4 closest ones and connect them..if your radio has rca connectors on it you can hardwire an amp for the 4 back ones..ulimately its up to how you want to hear the radio most of the time..

Impedance setting on Yamaha AV Receiver


Hi. You can always use a Receiver with an output impedance that is lower than the speakers input impedance.Problems arise when you try to use a Receiver with a higher output impedance than the Speakers input impedance.

I replaced the 2 ohm 6x9's in my buick with the monsoon amp, with 4 ohm 6x9's. After i put the speakers in, almost no sound came out. I've read that you can wire them in parallel from one...


If you did wire these in parallel to get the 2 ohm load, you will loose your balance. Also, you may have to bridge your amp.
To do this, go from the positive of the amp to both positives of both speakers. Then from the negative of the amp to both negatives of both speakers. If you have a 2 channel amp, you will have to bridge it. Note, make sure your amp is 2 ohm stable.

hope this helps

My kenwood headunit is saying protect and i dont know how to reset it and no wires are touching how do i fix this


Hi, this is usually caused by a short in one of the speakers or the speaker wires. Take the connector off the head unit and use an ohmmeter on each pair of speaker wires to check impedance. If impedance is less than 2 ohms on any pair of wires, check the speaker impedance for that pair. If the speaker impedance is low, replace the speaker--otherwise replace the wires. Please let me know if you have any questions, and thanks for using FixYa.

The radio is working but there is no sound coming from the speakers it was working I turned the car off and when I turned it back on no sound?


If you have high quality after market speakers with a lower impedance (2 ohm and 4 ohm) versus the factory speaker impediance (8 ohm 12 ohm and 16 ohm) your headunits sound out device is probably fried inside your head unit. that or all your speaker leads are fowling out at the same time which i would find that hard to believe. But the good new is, some of the newer head units have a low impediance fail safe, so you could have one speaker that is fowled out that is sending the head unit into protection mode which is muting the output until the fowled wires are cleared. Disconnect your speakers and turn the head unit up playing a cd or something, then connect each speaker one by one. You should have sound. hope this helps.

I would like to know what the best way is to cut out bass response in 4x6 and 6x9 speakers in a car w/o having to install a 4ch amp running in HPF mode. any suggestions?. i read about small inline...


You can indeed do this by putting a ceramic capacitor inline with the speaker wiring.
The circuit you have now goes Amp+ to Speaker+, Speaker- to Amp-
putting a capacitor inline means your circuit will go:
Amp+ to Capacitor, Capacitor to Speaker+, Speaker- to Amp-
Ceramic capacitors don't have a + or - side.

The next question is what value of capacitor do you want, and that answer depends on two things -- how much bass you want to cut off (the cutoff frequency) and the impedance of your car speakers (generally 4 ohm, but some are 8 ohm and some are 2 ohm)

Here's a spiffy chart that shows the relationship between cutoff frequency and capacitance. There's a lot of data there. If you get overwhelmed, here's a suggestion:
Assume you have 4ohm speakers, and you want to cut out everything that's going to a subwoofer (120Hz and below) -- you want a capacitor of about 330 uF (microfarad)

You can get those at any radio shack, or order online from someplace like Mouser.com

I have a 50x2 amp that is bridged 100 into a 4 ohm load. can i run this to a 6x9 3way speaker rated 100rms 4 ohm


Yes, you can. There's the impedance match between amp and speaker (4ohm to 4ohm).
The only issue I would say is that if the amp is putting out 100 watts RMS, then you wouldn't want to drive the speaker to the max, because it's rated at 100 watts RMS max, and at louder volume, it will start to distort and possibly blow from fatigue. Other than that issue, it should work fine.

Powering 4 6x9 speakers, need amp


Hi firstof all your deck isnt really putting out 52 watts x4 more like 17-22w rmsx4 ,companies like to throw out some crazy numbers it seems. If your into Kenwood try out a KAC-8404 4-channel on the mids/highs that will put 50 w x4 rms at 4 ohms or if you wanna go a lil louder try the kenwood x600f that will throw 100w rms on each 6x9 at 4 ohms no problem. My system is very similar to yours but running 4 pioneer 5x7's in all the doors and powering it with the 8404 its loud and clean ,fan cooled and no problems at all. My subs are a pair of 15's soundstream t-4's powered by an Alphasonik pma2500a its throwing 800w rms on each sub running in stereo at 2 ohms.It can drown out the mids if i set it that way but my mids /highs cant take as much power as your kenwoods can or else id step up to the x600f too.
