20 Most Recent Pyramid PB1281X Car Audio Amplifier Questions & Answers

Please make your question clear so that we at Fixya are able to help with a solution.
What is the sound driver you require for a car amplifier? Do you mean a head set, ?

This is the wrong place to post that. This is a amplifier section

Well if it is a humming noise (also can kinda sound like a turbo whining)

its more than likely a bad ground on your headunit or amp check that the amps ground is put on a solid part of your cars metal and get some sand paper and get the paint off before u ground it

other things to check before u go out and buy a filter is
check that the person who installed your stereo/amp DIDNT run the POWER for the amp next to the RCA leads or speaker wire this can cause alot of interferance too and isnt recomended at all .. power wire should be run on the other side of the car to the speaker wire and rca leads


if that fails to rid the interference you can go to anygood car audio store and ask for a filter for the rca leads and also a ground and power filter to elimantae annoying interference

also check that your airal is grounded correctly to the body of ur car over time it can become loose or corrode

hope this helps

Professional repair is required.

Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

the remote wire is just to turn the amp on and off. it doesn't really turn the bass up or down.

try: a shorter ground cable, a bigger ground cable or sanding the surface where you make your ground. a lot of amps will tell you the ground should be no more than 3 ft and for any the shorter the better

Hello sunshanel,

You did not say what you have the amp connected to and what the impedance load is. It is only stable at 4 ohms and if a lower impedance is connected, say 2 subs in parallel, it would try to produce more power when you turn it up and would most likely blow the fuse. 20 amp sounds right for the amp. The power rating of 800 watts per channel is peak power, not RMS, and many low-end manufacturers tend to state bigger numbers in the ratings.

Hope this helps.

Hi Linda, It's called a pyramid because it starts with one person putting money into a fund, Say it's a guy, He then invite as many people as he can(say 10) to do the same and then those 10 people invite as many as they can(say 10 each x10=100) and so on100x10=1,000) and on(1,000x10=10,000)... see how it grows... And what happens is the 1st guy gets a percentage of the money from the 10 people he invites plus a percentage from the 100 people they invited and it goes on and on, , the people he invited get a percentage of the people they invite plus a percentage from the people they invited and so on and on and it just keeps going and going and the higher on the list you are the more money you get but the lower on the list you are the more you struggle as it gets harder and harder to make money because everybody above you on the list are all getting a percentage from people all down the list until eventually everybody on the bottom of the list looses all their money and that's why it's *******......DO NOT DO IT, If you make any money from this scheme just know it's from people loosing theirs, Take care.........
