What would an "RCA Pre-out" look like? How would i get to the back of the HU?

Thanks for the uploading tip :)

Thnx :)

they will look the same as RCA inputs. On some HU's they will not be built directly into the HU, they will be extended out by wires. There will be one red, and one white, for left and right. On my old pioneer 5500 they were built into the actual HU, but on my 8600 the 3 sets all run to a little harness that plugs in, so they "hang out" from wires.

well you'd need to remove the radio, which usually involves some minor dashboard or center console disassembly, and a couple bolts holding in the radio mounting kit.
the pre-outs are just a red and a white female RCA connection, usually on a short cord about maybe 2 to 3" long.
RCA jacks are sometimes (improperly( called "phono jacks"
they are the same connectors you see on the back of any home audio receiver or television for audio-video connections.

I got behind there and the outputs have crimp connectors on them which should work fine but I have another question that comes to mind. Is it possible to run a Subwoofer signal wire off of one of the kenwood speaker wires (as they are close to where the subwoofer will go anyway). If I did that the power wire would odviously still run through the amplifier but could I come off of the signal wire?
Thanks!!!

Anyone? Could I split a speaker signal wire?

could you? yes. would it sound good? that's debatable.
using high level or high power speaker wires for signal to an amp never works really well for sound quality. you generally want to use a line level signal from a decent head unit

I have a problem with my HU or cd player (same thing?), it cannot be fixed (contacts are messed up).

I have two questions, first... is this just a faceplate or a cd player and faceplate together? (link at bottom)

Second, if it is a cdplayer and faceplate is it interchangable between vehicals?

Thanks guys :)

A head unit is the cdplayer/tape deck/dvd player basically.

That one in the link is both. All are sold that way, if not, something was probably stolen :) .

Interchangable? Absolutely, but you need a different harness for the next vehicle.

And honestly, I wouldn't get a cheap model Kenwood. I've seen plenty of them die within a year for no reason at all.

First off all, how much would a harness be? An average price since I assume they vary. Second, do you have a relatively inexpensive model you would reccomend? (it needs to have 4 channels which I think most do and if possible, also have relatively high rms/peak ratings on those as two of my 80 watt speakers wont be amplified, only the subwoofer is amplified and that a mono class d). It doesnt need to be 80 watts but a little more than 22 would be nice :)

Also, what is signal to noise ratio? Is 90db good? Is 100 db good?

Thanks :)
