impedance

I posted the other day about being disappointed in the Kicker Comp R I recently installed. Low output and distortion when barely turning up the gain. Today I decided to pull it out of the box and test the impedance. It is a dual 2 ohm sub. I set my multimeter to the 200 setting. The readings...

So I have been watching amp dyno videos because I need to replace my amp I've blown and I've noticed that as speaker impedance lowers, effeciency of the amp drops condsiderably and I want to know why 1 ohm stable amplifiers are pushed so heavily and everyone looks for them (hell every time I...

Im using a multi meter to ohm setting i have a Alpine R-W12D2 Subwoofer. dual voic coil It doesnt matter how i connect it the multi meter shows 8ohm? how is this possible if this is a new certified 2 ohm subwoofer? Can someone help me as I have 2 of these subs and I have a 1000 watt RMS JL...

I've installed four head units (HU) with speakers in my life and one complete system with HU, amp, wiring, and crossovers with never an issue. I can do the work if the instructions are clear. I'm no genius when it comes to all the issues matching components and installing them. Question: If a...

I am having a single voice coil 4ohm sub with 325w rms I am looking to buy a mono amplifier as i want to make full use of the rms. Also looking to buy another similar single voice coil 4 ohm sub with 300w rms(not 325w rms as earlier because it’s unavailable) Ques1 Is it safe to run two 4ohm...

Ok, decided to put this in the general discussion section because it will deal with subs and amps. I will also be posting this on CACO and MAF to get more information. I understand that impedance rise isn't always a bad thing. Enclosures are often very efficient when impedance is the highest...

Hi, I have a Pioneer GM-D8604 4 channel amplifier. Currently I have it pushing two speakers and 1 subwoofer fine. However, I want to add two more speakers to it, but I don't know if I'll be causing damage because my two current speakers are 2 ohm and on channel a. The sub is 4 ohm and on...

so you hear hype about a 1 ohm or even .5 ohm system. but why does that crap matter? If your system is 2 ohms at 2000 watts or 1 ohm at 2000 watts, are they not the same? I'm curious because I'm deciding whether to buy the 2 ohm dual voice coil or 4 ohm dual voice coil version of the same...

I looked all over google for this answer and can't find it. What determines a speakers ohms? is it the voice coil, the magnet, or both? does the thickness of the voice coil or how long the coil is or how big the magnet is have anything to do with it?
