Audio help

I have a 1988 Chrysler 5th Avenue that I want to install a after market stereo, but I have hit a rather small wall. I have the install kit, but when I was searching for the wire harness I found 2 things that kind of confused me a bit. I found this which they are saying is required for my car http://www.discountcarstereo.com/detail.aspx?ID=274

Now here is where the confusion comes in, I have also found this http://www.installer.com/item/display_item.php?it=71-1817


So which one do i need?


Also does anyone know where I can find a diagram on how to remove the dash?

The type of connection kit you use depends on the type of original factory sound system you have.

Most standard stereo systems and after-market systems have an internal amplifier that boosts the audio signal to a preset level. These systems are designed to connect to standard speakers, which are designed to match the power level of the unit.

The "Infinity" stereo systems used in Chrysler products are a little different. These systems do not have internal power amplifiers. Instead, these use special speakers, each of which has their own power amplifiers built in. The audio signal coming out of the unit is unamplified and the amplification process occurs in the speaker.

An Infinity head unit must be connected to Infinity amplified speakers in order to work. If you connect a standard speaker to an Infinity radio, you will not hear anything out of the speaker. Likewise, if you connect a standard, preamplified head unit to Infinity speakers, you will blow up the Infinity speakers.

What you need to do is determine the type of original stereo head unit and speakers installed in your vehicle. The "Infinity" systems are clearly marked. To be on the safe side, remove one "easy-to-access" speaker and see whether it is labeled "Infinity" and there is a power amplifier attached to the back of the speaker.

If your original radio (head unit) is not labeled Infinity and your original speakers do not have little amplifiers attached to the back of the metal frame, you should use the straight wire kit. Just be sure that the original speakers are designed to accept the power level of the new head unit you plan to install. If the power rating of the original speakers, in Watts (W) is lower than the maximum power output of each channel of the head unit, you will need to replace them with higher rated speakers. If you do not, you will blow up the original speakers. The power rating of each speaker is labeled on the back.

Now, if your original radio is labeled Infinity and your original speakers have little power amplifiers attached, you will need to make a decision, "Do I keep the original Infinity speakers or replace them with new speakers?"

If you choose to use the original Infinity speakers, you will need the power conversion kit (CHYAH adapter) that takes the preamplified signal from your new head unit and converts it to an unamplified signal before sending it to the Infinity speakers. The adapter is designed to accept a maximum of 30W per channel. Therefore, you must choose a new head unit that is limited to 30W per channel to do this. This set-up, however, does not make much since. With this arrangement, your new head unit boosts up the audio signal, the adapter removes the boost and the speakers add back their own boost. The new system will sound the same as the old system and use up much more power.

If you choose to replace both the Infinity head unit and the Infinity speakers, you can use the straight wire kit, without the CHYAH adapter. In addition, you are not limited to 30W per channel of power output in your new head unit. Just be sure to match the power rating of the new speakers to the new head unit.

I hope this explains your situation. Let us know what you have and what you finally do.
