Do The Pyle PLG6C need an amp? or can i just connect em straight to my stereo


It depends on your stereo you have installed. Some come with a good amp attached and others do not. I have a factory AC delco and it pushes them just fine. so the answer to that would be based on what stereo you have installed.

Hope that helps.

I have a 95 thunderbird lx need to know what wires are what for stereo.


Im not sure on the 95. But the 96/97 they had factory amplifiers in the trunk. You could install a new radio but you need to bypass those factory amps. Metra or another kit manufacture will sell you the harnesses you need. One for between the factory plug and the radio. Metra will have the wires labeled as to what they are to connect to. The other end of the wires should be your aftermarket. Which will be in the users manual or install guide that came in the box. If your trying to bypass the factory amps in the trunk and you get stuck. Head on over to the guys at TCCOA.com visit the forums and you will get more specific help from people who still own those cars.

If i hooked up all my aftermarket stereo wires to the maching wire. the stereo turns on but no sound comes out what should i do?


I would venture a guess with what little information you've provided (make, model, year...) that your vehicle had a factory installed amplifier. Take the blue wire from the new head unit and attach it to the power lead for the factory amplifier. Fords usually locate the factory amp under the passenger's seat. Chrysler infinity systems (Jeep) under the back seat etc... I hope I've helped. If so please rate my answer and leave a comment. If not, please re-post.

Hi Lo Adapters
Hi/Low adapters are devices that installers use to convert a speaker level stereo to RCA levels so it can be hooked to an external car stereo amplifier. You can cut the speaker wires and hook the hi/lo adapter right up or you can tap onto existing speaker wires without cutting them so the speakers still play while the tap gives you a connection to the hi/lo device for adding something like a subwoofer amp to the existing speakers.... We have hi lo converters in TWO CHANNEL and FOUR CHANNEL configurations and we have them WITH and WITHOUT adjustments.. The adjustable hi/lo converters allow you to fine tune the hi/lo device to match other levels in the car or to make sure the match between your stereo and amplifier is a good match.. The adjustable line converters are the most popular.. We also have some specialty hi lo converters that have special radio plugs on them that may plug right into your factory stereo.
Now you can install an amplifier with your factory radio or install a new radio with your factory amplifier!

I get a pop from the sub when the power comes on.


This is caused because the stereo you have put in, is a high power output, or higher than the factory and puts that extra power into the factory amp systems causing the amp to surge the power to the speaker resulting in the pop sound,most newer cars use a stereo system without an internal amp so as to reduce heat and a external amp in usually under a seat or dash and a high power stereo boost the output of the amp.

Can i connect the amplifier and subwoofer to the built ford fiesta radio


If your amp has rca jack inputs only you will need in-line filters to reduce the stock stereo speaker outputs down to less than 3 watts. If your amp has high power inputs you can use those. If your amp does not have a built-in crossover then you will need to install a low-pass crossover or filter before the amp so the only the bass comes thru or the sub woofer will have major distortion. Another problem is the amplifier needs a turn-on signal for the blue wire and most factory radios do not have one. That means you will have to tie that wire into the switched 12v wire from the vehicle so the amp comes on when the key is switched on. It can be done be done but I don't think you will be very impressed with the sub due to most factory stereos have a limited bass range. Most aftermarket head units have built-in crossovers and sub outputs. They also produce much better sound than the factory unit. So in other words yes you can.

Hooking up amp and subwoofer to stock radio


Are you sure that you want to attempt this?
It's a nightmare if you never have worked on any kind of car stereo. I've installed my share of after market stereos, so I know it's lots of brain work and patience.

The color of the speaker wires are the only wires that you can probably identify right off the bat. It's not too complicated to attempt yourself. If you have put in an after market stereo before. Your Lexus has factory installed rear deck speakers. Look at the bottom side of the rear deck. Pop your head in the trunk and look up.

On the right speaker there are 2 wires and on the left speakers there are 2 wires.

I think that all 1991 Lexus LS models came with factory installed rear deck speakers. The speaker wires are factory installed. You want to keep these original factory wires as is, but want some thicker higher wattage amp wires for your sub woofers, but write down the 2 left and 2 right speaker wire colors with the stripes, for example the red with yellow stripe, blue with red stripe, brown with orange stripe, black with white stripe and so on. There are four wires in all. Keep your wire colors on a piece of paper, because we come back to that later on.

You will need to run the thick red power cable to the car battery. That gets bolted directly down to the battery. You'll have to remove the bottom door jam that holds the carpet down. There might be a couple screws that you'll have to remove to pull up the jam. Tuck the red wire and lead wire in under the carpet and screw the jam back on when done. Do the same for the 4 thick higher amp speaker wires and route them to the back in the trunk.

Make sure to bolt the Black Ground Cable on the Chassis of the car for a good solid ground. The one thing that will cause a short is a loose ground wire or weak ground to the body.

Remove the radio from the dash. Be careful not to break the plastic around the radio. You should probably ask somebody for help, if you can not handle it yourself.

Now we need that piece of paper with the 2 left and 2 right wire colors with stripe laid out, you can do your splicing of wires. Simply splice the left and right speaker wires with the amp normal speaker wires that lead into the amp.
The amp may have stereo RCA jacks for input, I'm not sure which you have.

Make sure to match Left to Left and Right to Right. Now the AMP lead wire gets connected to the stereos power wire. This wire may be red or yellow, but I do not think it's gray. To test the wire splice into the yellow wire with the lead and start the car and turn it off. If the amp stays on with the car turned off, then change it to another wire. The goal is that it won't drain the battery with the car turned off.

There's some troubleshooting involve with factory installed stereos and making modifications. If you get this far you did a great job. You'll have it when the lead wire is connected and the car turns off and the amp turned off and when the car turns on and the amp turns on. Make sure you do not mess with the antenna wire. that turns on and then shuts off after the antenna is up.

Taking out factory stereo but dont know what wires are to what


There are adapter plugs available for most models of vehicle that simply plug in to the dash wiring of your vehicle. Then you simply connect the color coded wires to the ones on the aftermarket stereo you are installing. It saves a great deal of time and is much safer than trying to figure it out on your own and risking frying your stereo or damaging your car.

You haven't listed the make and model of vehicle, if you do I can get you a part number for the adapter plug you need.
