impedance

Hi everyone I need to replace/upgrade my 4inch dash speaker on my ‘09 daihatsu sirion/toyota passo I’am gonna install JBL GX428 but i just realize it has 2,3Ohm impedance rather than common 4ohm i use stock/factory head unit (Clarion PX-2716a-b) and i have no idea what output rating for this HU...

Say you have an option between dual 4 ohm and dual 2 ohm when purchasing the same sub. Theoretically, wouldn’t there be less of an impedence rise with running the dual 2 ohm at 1 ohm vs the dual 4 ohm at 2 ohms?

I have 4 JL 10" subwoofers, 2 of them are 10W3V3-4 (4Ω SVC) & 2 are 10TW3-D8 (8Ω DVC) I'm trying to wire them all to play from my JL RD1000.1 Amplifier for just a few minutes to see them all work. I read online I possibly can wire the DVC in parallel (2Ω) and SVC in Series (2Ω). Is this...

Hi there. Got my system clamped. JD1000/1 pushing a 12" CompQ DVC4 wired to 2ohms. My JD1000/1 is 1000w rms at 2ohm stable. No stability at one ohm. Clamp reveals 537w at 4.0Xohms. Since this is contingent off of the box, cabin, car, etc, CAN I replace my DVC4 with a DVC2 to wire it to 1ohm...

Hi. I'm from Poland, sorry if there's already a thread like this. Unfortunately I don't know the language and that makes it difficult to search the forum. Please help, there's a lack of information in Poland and the car audio zone is practically non-existent. Will this amplifier handle these...

Hi guys ... im currently running my 3in mids from the Left & Right (Front Channels) of my P450.4 Rockford amp. they are 4ohms each can my front channels support a load of 2 ohms individually so i can run 2x 3in mid's of the Left front channel & 2x 3in mids out the Right front channel without...

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?
