My amp is protecting unessacarily when ran at 2 ohms

I can run my amp at 2 ohms with one subwoofer and blow the sub up without it protecting. but for some reason when i add a second subwoofer in the parrallel wiring configuration the amp will go into protect mode almost immediately. this has occurred with both jl w3 subwoofers and image dynamic iq d4 subwooers.

Are you factoring the ohm rating from running them parallel?

2 x 2o subs parallel = 0.5 ohm (lowers ohm's)

2x 2oh subs series = 4 ohm

IT is posable that you are calculating the ohm rating fine, BUT some SUBS can reach lower ohm rating while hitting bass- i didnt know this till i had a rather insane sub that would dip to 1ohm while hitting hard bass causing my amp to go into protect mode.

So I just bought a kicker cx 300.1 mono block amp to run my 10 inch comp d 4 ohm 300 watt sub. I ran it parallel and it smells like the coils are burning. Help


That's only normal for the burn in period. Make sure you're not running it in 2 ohm by wiring the sub wrong. That amp is not really 2 ohm stable for a sustained period

Be aware your amp can deliver more power to a 2 Ohm speaker, but will not work if the 2 Ohm speaker somewhere in the audio spectrum comes beneath the 2 Ohm. Because you want the sub, to go as low as possible, it could be the speaker will have a very low impedance under 20 Hz, causing your amp to go in protection.
The power you give to the amp, will not be the cause it going in protection. It is sensing the output current, so it will stay in the borders the end stage can deliver. Try two speakers in series and give the same power. If the amp is not driven into the protection, I think you are closing in to what is causing the problem.

What puts out more power when subs are ran in series or parrelall


Depends on your amp, ohm rating of your sub, box dimensions and ports or chamber size, size of vehical.
Run the subs in 2 ohm if the subs and the amp can handle the demand. Look for the Qtas of the sub. You'll loose 1/2 of the control to stop the sub if you run it in two ohm. You'll blow the works up if any part of this equation isn't up to the task of a 2 ohm load.
If your budget, space allows, run it in 4 ohms at the max RMS of the lessor (sub and or amp) and add more amps for more subs for more effect. A very well designed box/enclosure with an average component list can make a wonderful sound. It will usually beat a bigger budget sub/amp setup in a generic box. Theres lots of science that goes into a great sound. Dig into it and have fun

This could be caused due to the impedance load being to low. Your amp is stable to 2 ohm load however its very possible that you have your subs wired to a 1 ohm load that would cause the amp to go into protect mode. The subs you have are dual 4 ohm voice coils and would need to be wired in series/parallel. I've included a link that will show you how the subs should be wired.

Amp goes into protection mode when i turn up volume


Sounds like you are running your subs at to low of ohm. Amps are rated differently on the levels of ohms or resistance that they can get to. If you have a dual 4ohm sub and run it in pairrell it will drop to 2ohm and if you run the same sub in series it will be 8ohm. Your amp will go into protection if the ohm is to low.

How to setup my fli900s amp ,just wont to know how to get the best sound out of it


In order to get the bass you want, you'll run your amp switched as a two channel amp and you'll need to run your subwoofers in 4 ohm Mono that's 450 x 2 to give you 900 watts of power.

2, 2 ohm dual voice coils ran in series and bridged on the amp for each sub.

Otherwise, Single Voice Coil 4 ohm subwoofers bridged to amp.

I have a JBL GTO 1201.1 mono amp and I have a kicker L5 solo baric with dual 2 ohm coils how do I run it to get the full power out of my amp?


You will not be able to get the full power from the amp without ruining your sub. The amp puts out full power into a 2 ohm load so option -A- is to just run one coil off the sub and it will absolutely pound -until you roast the coil.Then you can use the other coil and roast that one too. But since you do not want to roast anything-first thing to do is take it to the store and trade it in for a dual 4 ohm sub-wire the coils in parallel and there's your 2 ohm load to achieve max power from the amp. Problem there is that you will have WAY too much power for the sub to handle and you'll blow it anyways (in time).Best thing you can do is get an identical sub(dual 2-ohm) wire the coils in series which will make them 4 ohms per sub then parallel the subs to get back down to 2 ohms overall-you get max power from the amp and hopefully enough speaker to handle it.Hope that helps.

That's dependent on your subwoofers. You will need 2 dual 4 ohm subs wired in Parallel, a single dual 2 ohm subwoofer wired in parallel, a single dual .5 ohm wired in series. Or something similar.

Subwoofers won't work and they are brand new


Hello,

I've got a pair of these MTX's subs powered from a Fusion 450 watt 2-channel amp. For the price, they are great. By the way, they are 4-ohm.

My first suspicion would be that something in the first incorrect wiring damaged either the amp or the subs. Can you explain specifically what the "installing the subs incorrectly" means? Was the amp output shorted out at any time or was it operated without a load? Either of these conditions will fry an amp and sometimes, the protection circuitry doesn't work either.

First make sure that your amp is still working. Check both the primary power fuse, usually located near the vehicle battery, and the fuses on both sides of the amp. Make sure that when you turn the system on, the power light comes on steady (blinking is protection mode). Test your subs one at a time on a speaker output.
