 Subject: Wiring New Component Speakers
IP: Logged
Message:
I just installed Polk DB Series components in the front doors of my '00 QC Dakota, leaving all factory wiring and not installing crossovers. My tweeter pops when bass hits, which leads me to believe the factory amp has no crossovers in it. A few questions:
1. Does the factory amp have crossovers built in?
2. Can the factory amp do a *decent* job powering my new components and factory rear speakers?
3. Does anyone have a wiring diagram of the wires leading to and from factory infinity amp?
Thank you!!

There are no internal crossovers in the OE amplifier. There is only a small capacitor inline on the tweeter, which is why you hear the pop noise in the tweeters. You need to use the crossover networks that came with the new speakers. Use the speaker wires at the OE midrange/woofer location either in the door or at the amp's outputs for the inputs to the crossover networks and run new wires to the Polk tweeters and mids.
The factory amp does have a decent amount of power, about 20 watts x 4 channels and it will do a fair job on the Polks until you can get a better amp, but you may damage your new Polk tweeters if you continue to drive them without their dedicated crossovers. The whole set will sound much better with the Polk crossover networks too.
Sorry but I am at work and don't have any wiring info with me. Seems to me the wire colors were green/white for left fron +, brown/orange for left front - and purple for right front + and blue/orange for right front -. But I can't be sure from memory. If you need the color codes, post here and I'll see what I have on file at home.

Thanks Jimmy! Ever since I got my Dak i've planned a quality sound system but just don't have the cash right now so this should be a easy fix for the time. One would think there's a crossover in the amp because of the separate wires leading out to the tweets and mids but never assume anything, right.
If you have the wiring info on file at home that would be great if you could post it, I'd really appreciate it!
Also, what factory wires would you connect to the "input" on the crossover? The wires currently connected to the mid, the tweeter, or would you double them up to provide more power to the crossover?
-Thanks a Million!

I'll check my wire diagrams when I get home today and post the color codes. It's also probably on here somewhere if you search. I use http://mark.dodgedakotas.com to search the site.
There should only be one pair of speaker wires going into the door for each OEM set of mids and tweeters. If you look at the wiring in the door the tweeter wires are spliced in parallel with the midrange/woofer. You would use the wires at the midrange speaker and connect them to the input terminals on the Polk crossovers. Then run separate wires to the tweeter and separate wires to the Polk midrange. Doubling the input wires by using both the OE tweeter and midrange wires won't increase the power. They both are connected to the same single channel output from the factory amplifier.
Connecting the crossover input at the midrange location could require you to install the crossovers in the door, which is not the best place for them due to moisture, temperature and vibration. It would be much more reliable to install the crossovers inside the cab, maybe in the kick panels or under a seat and run your own wires to the amp output connections and the midranges and tweeters. This is not so easy to do if your truck has the molex type connector in the door jamb side of the rubber wiring boot but there should be a rubber grommet just below the boot on the door jamb to go through. Then you can make an incision in the bottom end of the grommet on the door side of the rubber boot to get the wires in the door. Then use split loom, heat shrink or vinyl tubing to protect the wires between the door jamb and the door.
I'll check my info when I get home and post the wire colors. I appreciate the beer offer but I am nowhere near Seattle. I live in a little town in rural Florida that no one has ever heard of.

Here you go, these are the speaker wire colors for all the speakers in your truck:
Right Front Spkr (+) Purple
Right Front Spkr (-) Blue w/ Red Stripe
Left Front Spkr (+) Dark Green
Left Front Spkr (-) Brown w/ Red Stripe
Right Rear Spkr (+) Blue w/ White Stripe
Right Rear Spkr (-) Blue w/ Orange Stripe
Left Rear Spkr (+) Brown w/ Yellow Stripe
Left Rear Spkr (-) Brown w/ Blue Stripe
If your 2000 is a late year production truck it could have a different wire harness, the one used in 2001 and up. When I was an installer I started seeing the 2001 colors in Dodges and Jeeps in about 1999. If the above colors don't match what you have, try these:
White/Red stripe Left rear +
White/Black stripe Left rear -
Tan/Purple stripe Right rear +
Tan/Black stripe Right rear -
Light green/Purple stripe Left front +
Light green/Dark green stripe Left front -
Light Blue/Purple stripe Right front +
Light Blue/Black stripe Right front -
In both a 2000 and 2001 the OEM amplifier is located in the passenger side kick panel. If I remember it right the speaker level inputs to the amp share the same color codes as the speaker outputs but the speaker output wires from the amp were the larger gauge. I think the inputs and outputs were all on one large molex plug in the side of the amp. It has been a long time since I saw one though. I hope this info helps you out.
