Question about Car Speakers & Subwoofers

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

Which amplifier is best suitable for me to use?


This really depends on the setup you intend to create in your vehicle.

The Amplifer (amp) needs to be matched to the speakers you intend to run.


As a rule of thumb, the power of the amp shouldn't exceed the max. power of the speaker (this may damage your speaker). Instead, the amp's RMS output power should be at 75-100% of the speaker's RATED (RMS) input power. NOTE: this must NOT be confused with max power.

Ideally, you want to run each speaker with its own amp channel.

A subwoofer will usually require a hi-power single channel amp, or a 2 channel amp, bridged into 1 (to increase power output required for the sub).

Here are some examples in simpler terms:

1 channel (hi power) amp can run a subwoofer.
2 channel amp can run 2 speakers, or 1 sub (bridged).
4 channel amp can run 4 speakers, or a combination of 2 spkrs + 1 sub (bridged), or perhaps 2 subs (bridged).

Hope this makes sense.

What would be the best size amp to purchase for two audiobahn aw1200 subwoofers and two pioneer 4-way 6"x9"?


First, I would purchase the amp based on the subwoofers alone. Allow unit power to run the 6x9's unless you are planning a intricate setup. Things to think about when buying your amplifier. Always get an amp that offers an RMS output of 25-30% greater than the combined RMS output of your subs. Also, the stability of the amp to handle ohms loads (1, 2, or 4 ohm stable). If you have two dual 4 ohm subs you can get a 2 channel 2 ohms stable amp, or a monoblock 1 ohm stable amp. This will get you the most power and sound for your buck. There are so many amplifiers out there at different price levels, it's really up to you. Hope this helps.

We installed the amp and bass package and the subs are not nowhere near *** powerful we think its the amp and when the remote bass switch when we turn it it doesnt change


what product brand did you install. do you set the amps x-over and gains a sub sonic filter right
need to see if the amp is on check led light on amp. make sure your subs ohm load is correct for the amp.

let us an example fake amp 500x2channel max output 1000watts

if you wire your subs at 4 ohms you 250x2 rms stereo
if you wire your subs at 2 ohms you 500x2 rms stereo
if you wire your subs at 4 ohm mono you get 1000 watts

if you have the input voltage of 14.4 all the time at the amp

whats the equipment power

Selecting an amplifier!


Buy a quality 2 channel amp. About 600 rms and set one channel as your highs using your crossover and then the second channel on "low" position for your sub. wire directly in to your low's channel with your sub at 2 ohms and then wire your speakers to the other channel.

What size amp do i need to run 4 1000 watt pyle 10's bridged


well first of all you cant bridge subs... you can bridge an amp... and for 2 they are probablly not 1000 watts, make sure you understand RMS and what the sub can ACTUALLY HANDLE properly... i would get a 1000 to 1500 watt RMS that is RMS RMS RMS RMS amp not one that says 2000 watts MAX POWER cuz thats cheap ****... get a kicker JL hifonic alpine or something in that category that actually tells you the TRUE power output of the amp... then run those 4 subs in a parallel circuit so its like really only having 2 subs. make sure then these subs do not run less then 2 ohms at the terminals while in a parallel, then bridge these subs acting as 2 subs not 4 to your TRUE 1000 watt amp and you should have a good powerful system

Amplifier For Powering Sony Xplod xs-l121p5


Pump the brakes!
You need to know the RMS power rating of the sub you are powering.
Dont exceed the RMS power rating of the sub by more than 25%.
If you see a peak power rating on either the sub or the amp, ignor it, means nothing. Always compare RMS ratings.
Example: a Sony 12" Xplod sub, boasting 1200 watts, will only handle, 350 watts RMS, so the amp you choose to power the sub should be 350 watts RMS as well, and should not exceed more than 25% of the RMS power handling (487.5 watts).
Bottom line, know your RMS numbers, not Peak.

Finding the best amplifier


Hello sharky75,

That 1600 watt peak power figure for your subwoofer can't tell you what amp you need. You need to know the maximum RMS power the sub can handle. And you need to know the impedance (ohms) of the voice coil(s). JBL GT5 series subs have an RMS rating of 275 watts. The GTO series handles 300 watts. The Power series handles 400 watts. The GTi series handles 700 watts. Some are single voice coil, so the impedance is fixed. Others are dual voice coil allowing you to wire them for different impedance loads.

For maximum performance your amp should be able to provide at or near the same number of watts RMS into the lowest impedance at which the sub can be configured. For example, if your sub is the Power Series Model number P1224, it has dual 4ohm voice coils and can be wired to present either a 2ohm load (parallel) or an 8ohm load (series). You want to wire the voice coils in parallel for the 2ohm load and select an amp that outputs up to 400 watts RMS into 2ohms. The Orion Cobalt CO8001 is just such an amp. If you have one of the GTi Series subs, a better amp would be the JVC Arsenal KS-AR75 which outputs 700 watts into 2ohms.

Hope this helps.

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

Subwoofers


This will depend on the amplifiers capabilities.

I will give 2 different scenarios.

#1 Stereo configuration

If the amplifier supports an RMS power output close to the RMS input power of the subwoofers then run the amplifier in stereo mode. For example 150 watts RMS X 4 channels driven at 20-20khz. (If you can provide a model # for the subs and the amp your looking at I can help you further with this decision.

Wiring for this is easy and simply involves matching the connectors for 2 of the channels (Front or Rear) to each of the subwoofers.

#2 Mono Bridged mode.

If the amplifier is lower power but mono bridgable you can bridge two Pairs of channels and power each of the subwoofers this way.

Generally speaking a 2 channel bridgable amplifier will be able to at least combine the wattage of each channel into a single monural channel and in many cases its actually higher.

So you would bridge the front 2 channels into a single bridged mode for one subwoofer. and then you could bridge the read 2 channels into another bridged mono channel for your other sub woofer.

For example if you had bridgable amplifier thats 50 watts RMS X 4 you coudl very likely (Generalization based on quality of amplifier) send 150 watts RMS to each subwoofer.

Again I would need to know what amp you're refering to to provide specific wiring instructions. Many Bridging amplifiers either have a single switch that will send them to bridged mode or you would use the positive + terminal from one channel and the negative - terminal from the other channel or a combination of both.
