Why am I getting a alternate he whining when RCA plug is plugged in speaker RCA jack is plugged in

Good wiring practices and noise reduction accessories can help cut back on alternator whine and ignition popping sounds thru auto audio systems.

Typically, amplifiers and other high current devices work best when power leads are direct connected to the vehicle battery. The remote on signal should come from the head unit or other location of choice. Use only shielded signal cables between head unit and amp. Try to keep as much space as possible between the audio wires and power wires - including speaker wiring.

By connecting to the battery directly, it acts like a giant capacitor. It is also where the cleanest, level DC power in the vehicle is - the further away from it you go, the dirtier is gets. Even only a slight AC ripple on the DC level voltage can wreak havoc on the sound coming from the speakers. You can add a "choke input filter" to further reduce the AC ripple. There's a ton of data on these filters, so I'll leave you to determine how far you want to dig - here is the Google result page:

Good luck!

I have a Boss 4x50watt in-dash stereo, 2 Pioneer 270-watt max/ 40 watt nominal rear speakers, and 2 Pioneer 500 watt peak/ 80 watt rms front speakers. Do I need to buy an amplifier? Or is does the head...

You do not need to buy an amp, the only reason to buy one is if you do not think it is loud enough when you turn up the volume to max. The speakers you have can take more power than your stereo can provide, but you only need to add an amp to get more power if you want it to play louder than it does now.

My ksc-sw800 kenwood subwoofer doesnt have audio output,i conected the power,+ to posite of battery and GND to negative of battery,..conected audio to input while my i pod is palying audio but no sound...

The P.Con is the terminal that is connected to the (blue with white stripe) cable on the back of your head unit. If there is no (blue with white stripe) cable then there will be a (solid blue colored cable). This connection is used to turn the amplifier on and off when you turn your head unit on or off. The power cable from the battery is to provide power and not to turn it on or off. Think of the P.Con as the ON / OFF of your amplifier. If you are unsure of how everything else should be connected, then send me a list of what you have (models please) and i will help you out. Hope this will help.

I am wondering what amp i would need for 2 JL Audio W3v3 - 2ohms. I am looking for something around 200. SHould I go with the Mono block and how many watts?

well you can go a couple different directions. you can wire them parallel or in series. parallel will get you down to about 1.3 ohms at the amp and series will get you close to 4 ohms. you need an amplifier thats stable at either of those impedances. the lower the resistance (impedance) the more power your going to get to the subs. I manage an electronics store and specialize in mobile audio/video. we are a 'Signature JL Audio Dealer' so i like to say i know the product line very well. JL makes an amplifier that is stable from 1.5 to 4 ohms and will put out the same amount of power at any impedance in that range which is really nice. Its called their 'Slash Series' you are looking for a JL Audio 500/1 amplifier. Grab an 8 gauge amp kit (4 gauge would over do it) and wire 'em up. Enjoy!

I have 2 10inch spekers in a box that just stopped playing the bass! can anyone help? ive checked the fuzes!

If the fuses are good , this could still be a prob with amp, check spkrs with a ohmeter(cheap one from the Shack or anyplace) by touching both leads to spkr terminals, disconnect spkrs first.Have ohmeter set to ohms Rx1 and you Test amp out put by connecting two spkrs that you know are good. Good luck and please rate this answer,thanks.

Cuts out at higher volume

Your amp might now have enough power to push the subs or you need to get a better amp kit that will deliver the power the amp needs to operate at a high spl lvl

I have hooked up a large amp in my ford ranger and I have turn signal and brake pedal noise (thumps) amplified through my sub

Are you getting the audio to the Amp from the Standard Speaker outputs from your head unit or are you using the low-level (non-amplified) outputs?

Amplifiers need clean (low-level) sound in order to work best. If you're providing audio input to your amp from the standard speaker cables that come out of your head unit, the amp will deliver poor sound quality & often engine noise.

If you're using the low level out's from your head unit, then try the following:

1. Make sure you've got clean power. Connect the Amp's power cable (through a fused link of some sort) directly to your car's battery. Don't attempt to tap in to the power from anywhere else on the vehicle (not only will you likely void your warranty if the car's new, but you'll also run the risk of screwing up your car and getting dirty power to your Amp). Garbage in, garbage out!

2. Make sure you've got a great ground (must be the same size cable as the power, must be securely connected at both ends, must be making a good connection to bare metal - I mean use a steel bristle brush or screwdriver to scrape off paint, clear coat, color, anything other then clean bare metal may not work).

3. Try relocating the audio cables away from power cables (both for the amp and other vehicle electronics). Example: BMW's have the battery in the trunk. The power runs down the right side of the vehicle, under the kick plate below the carpet kit. If you run your audio cable down the right side of a BMW, you're bound to get engine noise from the power cables. It's best to run the audio down the driver's side to avoid ambient noise bleed.

4. If you're sure that both 1 - 3 above are good to go, try getting a noise suppression kit - this company makes some of the best:

No power


Other than the +12V, the ground (-) and the 2 RCA inputs, normally external amps have also a remote trigger which switches it to active on. The remote trigger is activated by a wire from the head unit. Colors would either be yellow or blue but depends on manufacturer of head unit. Alternately, you can connect a simple toggle on/off switch to activate the external amp.

Additionally, pls verify that the 2 RCAs from your head unit are audio out and not audio in for aux source.

Good luck and kind regards.
