Question about Dual XAF-460 Car Audio Amplifier

1 Answer

In protection mode

I just bought a XAF 460 amp, It will be pushing a Pyramid 8" sub, I had everything connected (dry run) playing just the radio it sounds good. then I switch over to the cd player (6pk) that sound good, so as I started adjusting the gain the amp when into protection mode I reset it played for a bit a did the same. I doubble checked my connections eveything had a good but it continued to play a little then cut off. How much would the ground play in this? Because as I said this was a dry run, the grounds as I think back may not have been in a very good spot.The head unit is a Jensen cass/6disc cd.

What would be the best settings on a pyramid arctic 1000 watt amp for one JL audio w1 12

Your sub is a 4ohm woofer, running it in bridged mode + on right connection - on left connect as market on sub will give the best output. Your sub is rated at 75w to 300w and in this configuration will be getting just over 100w which about all the amp can provide with your sub/amp combo.
I don't know where they get the 1000w rating from either? the maximum the amp can possibly provide is 150w if running a 2ohm woofer in bridged mode.

Well i was driving one day and my subs just whent out so i bought brand new wires and hooked everything up but the power protector light turns red whenever uu turn it up past volume 10 i really do not know...

It sounds like your amp is going into protection. I know it's frustrating, but this is actually a good thing. If you subs you have are drawing too much power and the amp can't keep up, it will shut off instead of melting the board. Usually, the protection mode only last a few seconds. The user normally turns the music down that the protection shuts off and the music plays again. I recommend looking at a larger amp for your subs, if you are going to play them that hard.

Dual XAF-460 levels have all been messed with. What are the recommended settings?

Honestly listen to it buy ear. Thats the best way to "tune" your amplifer and your subs. I would turn your stereo to the desired volume level then start tuning your amp while it's playing. Make sure that you put the signal all the way down to start with and if you want it louder, that the signal level (knob) is the last thing you turn up.

Hi,just bought a 6x9 jbl gto937 speakers for my car,each speaker is 100watt rms and 300 max .Can anybody advice on what amplifier should i get for them?I know i can run them without any amp but think they...

Pyramid makes the PB series of amps. I have one that's driving a Sub.
The PB 700 puts out rms 60watts x 2 @ 2ohms, which gives you some "headroom" for your speakers. You don't want to over drive speakers with , for example, a 1000 watts for 100 watt speakers, because that's a good way to blow your speakers.
There are many brands and models of amps that will fit your speakers. Just make sure the amp will drive 2ohm speakers, since your jbl's are rated at 2ohm impedance.
You may want to consider adding a Sub woofer to your setup. A single Sub would fill in the low end very nicely. If you got a 4 channel amp, then two channels will drive your jbl's, and you can bridge the other two channels to drive the Sub. That would be a kick'n sound!
Just make sure the amp is bridgeable
For example, the Pyramid PB 1200 is a 4 channel, bridgeable amp. This particular amp will drive the 2ohm jbl's, but you would want a 4 or 8 ohm Sub connected to the bridged channels.

Green and red light are on my pyramid amp and its not working

It could be even simpler than that, yes an improper impedance rating on an amp will cause it to overheat, but should function temporarily until it reaches peak temp. If the outputs were blown the protect light should not light up being that they would need to work to cause the protect light to come on. I would double check all of your connections, one small little crossed wire would cause an amp to immediately go into a protect mode.

Car audio amp or speakers bad?

If you know how to use a multimeter, you can test the amp this way:

-unhook the subs
-hook up a cheapie speaker you know for sure works to one of the channels
-unhook the audio inputs
-turn the amp on
-set your meter to VDC
-put the positive probe on the inside of the input connector, being sure you make contact with th inner contact
-take the negative probe and tap it on the outside of the connector

What you are doing is sending a low voltage (replicating an audio signal) into the amp audio circuit and allowing the amp to amplify it. If the amp makes the speaker pop each time you strike the probe, the amp is working.

There is an inherent problem with band passes. The naturally filter out high frequencies like a crossover, including distortion, so it makes it hard to hear when the subs begin to protest.
