It is load resistance. set the amplifier switch to the resistance ( X amount ohms) to match your speakers. Although running 4 ohm speakers at the 8 ohm setting is louder, it will hurt your amp
most home/semi pro speakers are 8 ohm, while car speakers are 4 ohm. If you are doing a multi speaker pa/intercom install use your formula to calculate total load is 2 8 ohm speakers in parallel are four ohms . express them as fractions and add the denominator ie:8/1 +8/1 = 8/2 or 4/1 or 4. now connect that in series (add the top numbers)with another 2 speakers in parallel and you get back to 8 ohm load. repeat the same process over and over and you can hook up to 32 speakers to the amp without needing the 70 volt tap. hope this helped.

### 4-8 Ohm Output Overpowered?

You weren't by chance connecting a powered subwoofer to the standard speaker channels? Most powered subs require a dedicated output from the amp, otherwise you would be amplifying the signal twice over!

### Deciding which car stereo amp to purchase

Both amps driving their rated impedance will consume about the same amount of power. If you connect the amp designed for one ohm into a four ohm impedance load, it will output less power than designed and also use less power. If you connect the amp rated at 4 ohms into a one ohm impedance, it will output and use more power but at the risk of having it burn out since you are over driving the unit.

### I just bought two rockford fosgate t1 twelves duel voice coil 4ohm I'm running a old school alpine v12 1507 mrv 2channel. I want to bridge the amp to get the most out of these subs would it be better...

Hi there,
This amp should run comfortable at 2 ohms/channel. However, your dual voice coil subs are rated at 4 ohms. This means when you connect the 2 voice coils together in parellel (positive to positive and negative to negative both coils wired to one output) the amp will see 2 ohms. So if you connect both subs to one output then your amp will see 1 ohm (not good) If you run the voice coils in parellel but the subs in series then the 2 resistances (ohms) will be added together. So that way the amp will se 4 ohms. This is fine but the amp would push more power into 2 ohms. You can run one sub on each channel if you can split the head unit output to 2 outputs, problem is then you will be halving the amount of power to each channel. Personally I would probably be more inclined to run 1 sub on this amp and run another amp from the pre-outs on the first amp for the 2nd sub. Try to find another amp the same to run the second sub. Mind you, 2 of these amps will need some big power cable to run them but should shake your teeth out!
Hope this helps

### I have a budda superdrive 30 II amp and have a setting question. I made a 2-12 cabinet to hook to this amp. Each speaker is 4 ohms. They are wired to their own output jack. My amp has 2 outputs for...

You best rewire the cabinet to put the two speakers in series. Wire one speaker plus to minus of the other and bring the other lead, one from each speaker to your jack on the cabinet. The amp output impedance is what is set on the switch... for two 8 ohm speakers you would use both jacks to the two speakers BUT ssince you have 4 ohm speakers the ONLY option is for two in series and set the switch to 8 ohms. The amp is ONLY 30 Watts so don't expect too much sound output... You should get a nice CLEAN sound at a reasonable level. If you drive the amp too hard it will clip and you will get garbage.

### My kenwood kac 9103d just crapped out on me and i am looking to buy a new amp but when i bought my sub the guy specifically wanted to know what type of amp i had to match it to the sub. so now do i have to...

More specifically, the amp must support the resistance of the sub, or subs. If your amp is 2-ohm stable, it can run a sub, or subs wired for a 2-ohm load. Also, whatever the recommended maximum wattage is for the subwoofer, try not to exceed this much, if at all, with the amplifiers wattage.

### NOT SURE WHAT OHMS SUB I NEED!

if you get the 4ohm you can wire it to run a 2ohm an the kenwood amp will push 900 watts at 2ohms.they say it can push up to 1800 watts,that would be at 1ohm.that kenwood runs 500 at 4ohms an 900 at 2ohm.if you need help wiring the sub or anything else let me know bertman285@hotmail,com Max Power Output 1800W Power Output 4 Ohm [14.4V] 500W x 1 [20-200Hz, 0.5%THD] 2 Ohm [14.4V] 900W x 1 [100Hz, 1.1%THD] Bridged[4 Ohm] -

### I have rotel amplifiers when i connect my speakers the amplifier stop working

check the ohms on the amp output and the amount of ohms on the back of your speakers they should be the same (or at least the amp should be more) ....your speakers may be overpowering your amp

### 2 ohm speakers wont work on a lanzar max pro 4000 watt

The 2 ohm stable rating on the amp is PER channel meaning that you could effectively hook up a 2 ohm speaker or a 2 ohm load to each channel without the amp getting f"d up-butin bridged mode it will only be 4 ohm stable. to achieve a 4 ohm load with your sub the type x wire the coils in series that will get you at 4 ohms to run in bridged mono .But you will get the exact same amount of power if you wire each coil to one channel of the amp as bridged mono sees the sum of your 2 ohm channels combined-Hope that helps.

### 2 svcs

You've pretty much hit the nail on the head. Two 2 ohm subs in parallel would give you 1 ohm, and two 2 ohm subs in series would give you 4 ohms. 1 ohm would be overloading the amp but 4 ohms is slightly "underloading" the amp.

Your best solution with the gear you have (i.e. not buying new subs or a new amp) is to put the subs in series (4 ohms). True, you'll be putting about 200W into each sub, but according to page 4 of the owner's manual for the subs, 200W is just a tad under the optimum level recommended for the sub anyway.
