The Protect light would normally be Red. You need to test your RCA's and make sure your getting a signal to your amp.  I would just buy a new set  or if you have another set just try them.  If you get your amp to power on and all of your voltages are right with the proper signal and your amp fails to turn on you Have a bad amplifier

I have an American Pro amp V.S.-1406. It has the amber lights on inside but no green power light. I am almost positive that everything is hooked up correctly but it just won't work. No sound. Good...


If you have no power light on or its not green or the color it's suppose to be when working properly then it's in protect mode. First unplug everything except the power wires and see if any of the lights change from amber. Being the color is amber this means its in protect. if still no green light for power or what color it's supose to be when working properly then you have an internal problem. Mostlikey the powersupply mosfets and/or the output transistors or mosfets. I have to look up this amp to see what it has for outputs. With a good ground and positive power wire hooked up, your amp has some shorted components. I own a small business repairing, selling, and installing car audio. I am MECP certified also I'm an electronics engineer and have designed 2 mono sub amps that sold very well. Saving up to have more built again. I have 20 years experience now so I have been doing this for a very longtime. My pricest are the cheapest and my work is professional. I do it cheap cause I'm tired of seeing people getting ripped off at allot of places and my overhead is'nt high. I also offer services that no one else does and I offer online video help to help a person test certain components berfore sending an amp in, or over the phone. If you need help just contact me through here and I will send my info. I get allot of business through this site and diycaraudio.com plus a few other sites. Hope this helps. I will look up your amp if I can find a manual to see what color the lights on it should be when working properly. Being amber though, in my experience that means it's in protect. Do what I asked first to rule out bad subs or RCA's causing it to go into protect.

I have a 1100watt sub woofers, and a 1000 watt amp. Will the my sub woofers, or amp blow out or get damaged.


Are those rms wattage?

Anyways, your subs (if you have two) will double the power of your amp, meaning your amp will be under powering your subs. Nothing will get blown out but will never see their full potential. But if you were to use single sub with your amp then you are more likely see the full potential of the sub and amp.

2 subs=2200 watts is just twice the power of the amp output power!

What size amp needed with a sony explod player?


this bandpass enclosure is rated peak power at 1200 watts . what this means is that each subwoofer in the is peaked at 600watts to make 1200 watts . what your looking for is to power up the subs with rms continuous wattage . you need an amp that will put out 400 to 500 rms a channel to run this sub enclosure at 800 to 1000 watts rms to keep the speaker from blowing


audiopipe apf1801
71671968.jpg this amp will give you 1 channel @ 4 ohm x1 350 watts 1 channel @ 2 ohm x1 900 wats 1 channel @ 1 ohm x1 1800 watts you would have extra power for better subs with more power later but you get 900 watts which when connected right would mean 450 watts per sub be perfect for you . i sell this for $320.99 in my store can shipp any where in usa to contact me caraudioquestion@gmail.com

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

What do the various led light colors mean? I have


The LEDs each indicate something is conected or normal. There is one for hard drive activity, power, battery, and wireless. Blue is good. Orange is bad. First take the charger to a shop to have it checked. If bad replace it. If good the the problem is either battery or the connector on laptop. Since the battery is new it sounds like the connector to me.

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

Trying to figure out what kind of amp i got amercian pro vs-3507?


The VS3507 Is a class D monoblock.
Your optimum wiring for this amplifier is a 2 Ohm load - so it produces its full potential power of 350W RMS.

To Achieve a 2 ohm load, the most common load is one of the following...
(1) Dual 4 Ohm Voicecoil Subwoofer Wired in Parallel.
(2) 4 Ohm Voicecoil Subwoofers wired in Parallel.
(1) Quad 2 Ohm Voicecoil Subwoofer wired in Parallel/Series.
(1) Single 2 Ohm voicecoil subwoofer.
