2 ohm or 4 ohm??
I'm planning on upgrading my stereo to either an arc amp, or the new hawgtunes 160 watt, and I want to know how Harley runs theirs from the factory, 2 or 4, and why? I know that if you go one way you can get the amp's full power and if you wire it the other way you can only get about half of the power. Why is this, and does one way give you more fidelity than the other? Thanks for your help in advance.

Ok...
I don't know about the hawg wired amp but for the Arc Amp you'll need to get 4 Ohm speakers to connect to the amp (that's what the amp is designed for). If you use the stock speakers that are 2 Ohms you'll will cause the amp to run hotter and actually put out more wattage which sounds good until you blow the stock speaker (as they are not rated for 250 Watts that the Arc amp will put out). So if you are upgrading the Amp go out and get a good pair of 4 Ohm speakers to go with the amp (I have some Kappa Infinity 62.9i).
Now for your second question: There is really no difference in fidelity between a 2 Ohm and a 4 Ohm speaker. Since most amps are designed for 4 Ohms you'll have better luck finding 4 Ohm speakers that are high quality then comparable 2 Ohms.
I hope that helps!

yeah, you got that kinda wrong there. the arc amp is rated at 125 watts per channel into 2 ohm, 75 watts per channel into 4 ohm.

Thanks! I couldn't remember the wattage.

Every amplifier is designed to handle a certain load. For home amplifiers this number usually starts with 8 ohms. With car amplifiers it is usually 4 ohms. All amplifiers can handle a higher resistance (load), but they will produce less output. Most quality amplifiers can also handle a lower resistance. Most car amps can handle a 2 ohm load.

Hogtune amp
I just installed the new 160 watt ultra hogtunes amp yesterday. I was impressed the first time I turned it on. Finally have the bass I was looking for. I have the hogtune speakers and the tweeter pod also. One thing you will have to watch for is if your speakers can handle the wattage some of the amps available will pump out. The hogtune amp wattage ratings are lower than some of the other amps out there but I found it was plenty and cost somewhat less to purchase. Many choices out there that is for sure.
