Sub is unresponsive

I have a fli 12 subwoofer and amplifier package. i think the amp has 200w rms and the subwoofer has 1000w max output. it was all working fine for about a week. however whilst driving the subwoofer was making popping noises occaisionaly, usually when i turned lights on or main beam on. next time i turned the car on however the subwoofer failed to turn on. the LED is not even working. i have checked all fuses and wiring. i dont understand what can have happened?

thanks bill

And i would say that the best use of this amplifier would be for sub-woofers.

Kenwood kac-7204 1000w amp with 12 in sub what size wires nedded to use


bigger the better my friend. Look at your Peak RMS output, and how long of wire you need. Then you could make the judgment call on how thick or what gauge you need. (2 involved factors power + distance). id say 10 gauge and you would be fine.

What is best amp to run 2 12 inch cvr's


12In Kicker CVRs
are Dual Voice Coil, and You can run each voice coil around 200 Watts RMS

So each sub will have a 400 Watt RMS and 800 Watts peak.

Now since you have 2, Your total will be 800 Watts RMS and 1600 Watts Peak.

I would get really any amp that sits at around 800-1000 Watts RMS.

These are kicker but they are low end so i wouldnt push them to the extreme.

1000-1200 Watts RMS Max and but keep the Gain down on the amp. They will hit no doubt but i wouldnt push these subs or you will be disapointed in the long run.

I would get a Fosgate or MTX amp.

You can get any amp really but find something right around 1000 Watts RMS and it will push those well.

You can go mono block or a 2 channel, just depends on how you want to wire them.

Be careful though. If your running them bridged right now with your mono block, do not run them parallel bridged on a 1000w RMS Amp, you will blow them so fast lol

(RMS = Root Mean Square. Or in other words is the continuous wattage being sent from the amplifier to the subwoffers)

Support Question about RMS


you are going to need an amp that can supply the right amount of rms power to make it sound good. these sony subs are rated for 380 watts rms. so in order to find an amp that will supply two, you must multiply that figure by two. so you will need an amp that can supply around 500 to 750 watts continuously (or rms). also you are going to want an amp that is either class d or class ab rated. these amps are built to push subwoofers exclusively and will give you the best efficiency and sound out of your subs. you will also want to get an amplifier is a monoblock amp, and not a stereo amplifier. make sure the amp can put out that rms rating at 2 ohms as two 4 ohm speakers equal 2 ohms wired in parallel. i have a kenwood kac9152d that puts out about 2000 watts max at 2 or 1 ohms (900 watts rms) that i used with my two sony xplod 10's for about 2 years. it was kick ***! now i dont know if you need that much power but they will handle it as long as you dont push them too hard for long periods of time, otherwise you might end up blowing them up! (depending on the box size that is, and the quality of it as well...)

i have years of car audio installation experience and can help with setting up and wiring any mobile entertainment system you can imagine. may i ask what kind of music you listen to and what kind of box do you have for these subwoofers?

if you have any questions email me at thadoggma420@hotmail.com

Knocking noise with my kicker compvr 15"


comp VR 15s are rated @ 500W RMS 1000Peak.
The lanzar vibe amplifier is 2 x 600W RMS at 4 OHMS 2 x 1200W MAX at 4 OHMS 1 x 2400W MAX at 4 OHMS Bridged 2 x 1000W at 2 OHMS RMS.
Your subs are single 4 ohm subs.
If your subs are wired stereo, they both are seeing 600W. (more than the rated RMS)
Chances are, you have them wired parallel to a 2 ohm mono load - of which that amplifier is not rated. In theory, it will produce about 2000W @ 2 ohm mono for a short period of time.
Your amplifier is too powerful for your subs. Turn down the gain setting to 3/4 or purchase better subs. Also be sur the subs are inthe proper enclosure. It sounds as if they are excurting past their linear x-max and colliding with the rear bump plate. This will cause damage down the road if left as is.

How do i wire a qvc subwoofer to a 3000w 1ohm stable monoblock amp


depends on the amplifier if you have a mono block amp or a regular 2 output amp if it is 2 output make sure to bridge and that means the negative to one output and positive to the other output then need to find out the rms on the speaker. the amp should have the ability to adjust it you might want to get a digital multimeter set it to watts and make sure you only set it to the RMS of the speaker because max handling should be the 1800 and usually the RMS is half the max so it should be 900 w again it depends on the amp and were the adjusting knob is and or if it has one
