So Cal | I was thinking of getting new speakers for my Vision... How many ohms am I looking for, 2 or 4? I can't find that info anywhere...

| Before you ask what brand people recommend, don't. Check them out and decide for yourself. The only thing most people agree on is marine speakers are better. |

| My 2011 came with 2.6 ohm (ie. 2 ohm) speakers.

| Send screen name "ditch" a message. He is one of the speaker gurus here. He was able to fit 6.5" speakers in his dash. I got to hear them 2 weeks ago. Unreal, huge difference. I could here his stuff over my J&M's at speed! awesome |

My 2011 came with 2.6 ohm (ie. 2 ohm) speakers.
I made the same assumption that I could tell the rating of the speaker by putting a meter across the leads and reading the resistance. Turns out it doesn't work like that. I don't remember the details which can probably be found on the Internet but they use a different method for rating speakers. My 4 ohm speakers also read 2.6 ohm with my meter. The tech at radio sound set me straight.
I found the explanation:
So, how do you tell what the impedance of a speaker is? On most cabinets, it should be printed on a label next to the jack. If the speaker is visible, it may be printed on the speaker label or stamped on the frame or magnet. To measure the true impedance of a speaker or cabinet requires a rather complex procedure involving signal generators, power amplifiers and high frequency AC voltmeters. However, with raw speakers and many cabinets, the ohmmeter function of a digital multimeter can help you identify what the impedance of the speaker should be. Generally, the reading given by an ohmmeter will be about 2/3 to 3/4 of the impedance of the speaker. So, a 4 ohm speaker will typically measure about 2.5 - 3 ohms, and an 8 ohm speaker will typically read about 5-6 ohms, while a 16 ohm speaker will measure around 12 ohms.

I didn't measure, it was printed on the magnet I believe.

| I was thinking that all this sounded very familiar, like we had discussed this before. Sure enough, I found the post from two years ago :-)

We got into the impedance on page two I think. Pretty funny how this stuff keeps cycling through.
