I have a Jeep Wrangler 2001 TJ <br />
I have just enough skills to replace a speaker without too many modifications. <br />

I'm looking at this comparison:<br />

<br />
The instructions say they will fit if they are replacing stock speakers. How can I tell if they are stock?<br />
<br />
Which one above is better or can you make a suggestion? I am replacing these roll bar speakers, console sub woofer and dash speakers. <br />
<br />
I'll try to post a related post for an amplifier.

Digital audio is technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form. Following significant advances in technology, digital rapidly replaced analog audio technology in most areas. Digital audio systems may include compression, storage, processing and transmission components. It is important to distinguish between the audio coding format, the codec performing the encoding and decoding of the raw audio data, and the container file. Common file formats include .wav, .aiff, .au, .m4a, .mp3, .wma, .ra and .raw.

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
