We all assume that you're wanting to add an amplifier to your setup and that's why you considered going with the Legacy CD player instead of the Kenwood unit due to the Kenwood's lack of RCA preamp outputs. Is this right? That's what you're wanting to do?
A line-output converter (which is what everyone is suggesting that you buy rather than "upgrading" to the Legacy head unit simply because it has RCA preamp outputs) is a device that will hook up using the speaker-wire outputs from your existing Kenwood stereo and convert that input signal to RCA preamp outputs which can then be sourced into an outboard amplifier.
Additionally, some amplifiers have a speaker-wire input option and do not require the presence of RCA patch cable signal transfer at all.
A step to a Legacy product won't be an upgrade in any sense of the word (even when compared to that entry-level Kenwood that you have) Keep what you've got and just get what's needed to incorporate it into a larger system that you currently have. I'd wager you'll be much happier...but that's just my $.02. //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
where could i find one of those converters for my HU Kenwood kdc-119?
The type of converter that's being discussed isn't specific for any one particular head unit. It's for use with any deck that has speaker wires meant to power speakers whether it be a Kenwood, a Pioneer, a Legacy, an Audiobahn, an Alpine, etc, etc, etc.
They can be found at Wal-Mart, Circuit City, Best Buy, and pretty much any other place that sells car audio gear. Like previously mentioned average pricing will run in the neighborhood of $20.
