Re: car stereo

You probably need to find a beter place to earth it, try this, if the problem persists check that both sides of the earthing are connected efficiently. if this still doesnt work you may need to purchase a new earth wire thats bigger.

Gt5 12 inch 275 watts how many watts of amp best?

Depends on what output your stereo is. If you underrate the speakers (speaker watts is less than stereo output), the unit will sound louder for a while, then you end up blowing your speakers with the excess distortion. If you overrate the speakers (speaker watts is higher than stereo output) the speaker will not operate correctly and the distortion can damage it also. Its best to get a close match. Slightly higher is better. It is important you know actual wattage output not PMPO ( Peak music power output) A lot of stereos are rated at PMPO. The higher number sounds great but in reality, the figure is the MAX output and by then the sound is distorting badly. Distortion ruins more speakers than anything else...

When i turn the volume up to(17-20) my sound cuts out and my speakers make a cracklin noise.i have bought new speakers and rechecked all speakers are rated at 50 watts rms and my stereo pumps out...

It seems you needs more power to maintain the level of good sound.Maybe the maximum volume is 30 - then the mininum is 15 and you can't hear any cracking sound. If you exceed 15 the minimum, as you said starting 17 - 20 you hear crackling sound .Then you reach ,what they called the "cliping level"so much distortion and crackling sound,your stereo too small to accomodate .You must add a power amplifier so crackling will gone and to fit your listening pressure...

Hope it may help you;

I have some music and videos on a sd card but when i put the card into the p7290 plant audio radio slot it begins loading then just stops. would also like to know why when im listening to the radio the...

The sound issue could be due to the offset not being set correctly there should be an option for that on the stereo functions. Depending on the units capability's from a format stand point that could be the issue, check and see what type of files are on the card. Then see what kind your receiver accepts, then if they do accept them find another way to make sure the Sd card is viewable. The slot may be damaged.

Help: pioneer headunit install into a ford corsair 1990.

This is tough, You need to find one that gives continuity through it when the keys are off, and on. These are the positive wires which is your constant, and accessory. The constant is always powered so when the key is turned off, it's purpose of giving power to the stereo for memory(stations,clock,presets) will work. The accessory as we now know only turns on with the key turned. Finally the ground is a negative, and must not touch the previously mentioned wires. Test for continuity against metal, and probe the suspected ground wire for continuity.
Once these wires are correct, splice them together and the radio will turn on. Now you have the painful process of hooking up one speaker wire,(from stereo) and touching the other wire same color to the other wires in your car to make the speaker work, the more you get the faster it goes as you will weed out incorrect wires since you already have some that work. Once you know a set of 2 wires works for a speaker, make sure it is the correct speaker location, as white and gray are front speakers, and the green and purple are rear speakers. This is longer than knowing the colors, but once completed, you can label the wires and have them known for future technicalities.

sorry your car was not on my wiring list, so no info.
Any questions feel free to ask!

Crysler lhs, static buzzing noise in speakers when accellarating?

This is usually indicative of a ground loop causing noise from the vehicle electrical system. Long story short your stereo isn't grounded well enough.

There are two possible solutions:

1. Ground all components to the same point. This will reduce the potential and should greatly reduce any noise.

2. If number 1 is not possible (and it often is not), use a "ground loop isolator", available at nearly all electronics stores, or car audio suppliers. This device prevents a direct electrical connection between the two sources and will usually fix the ground loop.

Fitting a Kenwood car stereo to a 2003 Toyota Hilux ute, all works well until aerial lead plugged in, then immediately the fuse blows that feeds park lights, dash lights, instruments etc. Car stereo works...

The vehicle chassis ground or negative is opposite to the stereo. The aerial is vehicle chassis ground (earth), when touched to stereo results in direct short. If the Hilux is positive ( + ) chassis (earth) and the stereo is negaitive ( - ) ground, there is the short. If this is the problem, either replace with a compatable stereo or compatable vehicle.

I have a Kenwood kdc mp828. I disconnected my battery cable and now can not remember my security code. I need to reset the unit so I can again listen to my stereo.

I read a blog on your site about Kenwood stereo's. I used that information to unlock my stereo security code. Albiet, I did have to figure out a bit of the code needed myself. I am again able to listen to music on my stereo.

Subwoofers and amps

If you replace the head unit, that will make a big difference. If not, then it really depends on the type of music you primarily listen to. From a single sub setup, an 8 or 10 in a sealed box is best for punchy base, i.e. alternative, hard rock... A 12, 15, or 18 is designed to reach those lower bass frequencies and are suited better for ported enclosures. I.e. Rap, bass heavy Regge, etc...However, that's not to say that you can't go back and forth between them. The main difference is that a 10 and below tends to be more accurate, and can follow the kick drums, for example, a lot faster than larger woofers. Determine what your primary listening music is, what you want out of your system, and a maximum price for everything first. Then, I can suggest woofers, amps, etc.

Everytime i turn my car off and take the key out of the ignition all my stereo presets reset. all connections made are correct, however there is one wire which is left over. it is orange with white stripes...

Most stereos have two power connections. One is "constant" (aka always connected to +12V) and the other is switched on/off by the ignition. They may go be various names. The idea is that the constant +12V keeps the stereo from losing all of the settings while the switched power turns the stereo off when the key is not on "start" or "accessory". It sounds like the both connections may be made to the switched power on your car, causing it to go completely powerless when your car is off.

Are the presets reset after you turn the car off or only after you turn your car back on? If they only reset after turning the car back on, it's possible the battery and/or electrical system is having trouble keeping the system voltage up while the starter is trying to turn the engine.

The illumination signal is usually used to let the stereo know when you've turned your headlights on, so it can dim the display automatically. Should be completely separate from your issue.
