If you have a rear DVD (VES?) system and you install an aftermarket head unit, do you lose the ability to hear the DVD player through the speakers?

But the REC is capable of hands free blutooth calling. I don't understand why the OP doesn't just keep the stock REC and add uconnect? You can even get the factory iPod adaptor for streaming, or even stream through the VES (if equipped)

I installed an aftermarket one so I'm not sure.

We finally got the stereo and adapters from crutchfield. Took 10 days!

So the instructions for connecting the wiring harness require knowing if the factory system has an amplifier. Im thinking we dont have one? The factory system I have is the 6 CD changer plus Sirius plus AM/FM. It was called Boston Acoustics.

So is there an amp or not?

If not, then I hook up front and rear speakers, if so it says to do things differently and that there would be no FADE control? Im a bit confused about this part. I will call Crutchfield too to be sure.

See my post above. According to Crutchfield tech support, the boston acoustics system does have a separate amplifier. This means there will be no fade control. Thats too bad because we use the fade control.

So does this mean my stereo should be louder? I will have the amplifier + kenwoods built in 22w per channel?

The wiring is more involved than I expected. The others who repsonded on this were correct. The wiring harness adapter is not brand specific. So I have to solder a bunch of wires. The instructions are not really that clear but I think it should work out fine.

The amplification is not additive. You'll still be using the factory system's amp so it'll be fairly close in loudness to the stock head unit. However, you'll likely have more control with the Kenwood so the apparent loudness may be more depending upon how you tweak your settings. I did more or less the same thing with my JK. I kept the factory Infinity amp and wiring, but upgraded the speakers, baffling in the speaker soffits and put in a Kenwood Nav head unit. The sound was so much better quality, that I didn't need to turn it up as loud as the stock system.

Thanks for the info. I didnt like to find out that there will be no fade control the day of install. We use fade quite a bit and will probably miss that.

Since we are only using two speakers output from kenwood, that means only half the kenwood amp is being used. Well if we dont like it, I guess I can put the stock unit back in and put the kenwood in my truck.

Not exactly. You won't be using the Kenwood's built-in amplification at all. Essentially, the interface from Crutchfield is taking the L/R output from the Kenwood and distributing it to all four channels (2L and 2R) of the factory BA amp. So you're still getting 4 channels of amplification, it's just that in the conversion process, you've lost the ability to fade front/rear.

If you wanted to maintain fader control and use the Kenwood's built-in amplification, you'd have to completely wire around the factory BA amp, wiring the Kenwood directly to each speaker using new wire runs.

Im not impressed with the aftermarket stereo. Its great except for there is a low hum noise that can be heard whenever the radio is turned on. It does not change with engine off or on. It is not affected by turning volume up or down. Once I play music, I dont really hear it, but its there. I can barely hear it with windows up and engine running. With engine off it is really noticeable. I figured it might be a ground, but Im pretty sure I grounded it correctly using the wiring harness.

I called crutchfield and they said something must be interfering with the control box and I might try moving it or using a power filter. But they gave no indication on where to get or how to use the filter. They said I would get this noise no matter what brand aftermarket stereo I use.

Whats up with this?! I dont want to spend hours chasing this. Is it Kenwood specific or the wiring harness? I followed the wiring directions pretty carefully.

I had the same problem. It was with the wiring. All i had to do was connect some of the wires. Once I was done I didn't have the hum.

Does anyone have an aftermarket radio that doesnt have this hum when using the stock amp and the radiopro rp4-ch11 interface?

The wiring is connected, soldered. The tech support hasnt been too helpful. I ran an extra ground from chasis to the wiring on stereo and that made no difference. I removed the deck and the SWC box out from dash and it still makes an unacceptable hum.



So my options are pretty limited, I could try another brand like alpine or pioneer or I could just send this all back to Crutchfield and reinstall the stock HU. I guess I could rule out the SWC connector and harness by wiring to some external speakers, but that would be a real pain.

I did some more trouble shooting. I hooked up another speaker to one of the speakers wires that werent be used. The hiss is still there. Crutchfield agrees that there must be something wrong with the kenwood hu. They are sending a replacement. Hopefully this will solve the problem.

Bummer. I've personally never had any issues with Kenwood gear, but SH as always. Crutchfield will take care of you. Provided you have everything wired correctly, there has to be a faulty piece. It should be as quiet, if not quieter, than the stock system.

Crutchfield will definitely take care of you. They had an answer for every question I had. They walked me through everything. My biggest issues was the wiring. I had the same him, but when I fixed some of the wiring (with their help) the sound was gone. It's clear as a bell now.

It would appear that adding an aftermarket radio in a newer vehicle is a real pain.

We are now getting check engine light and problems with TPMS. Ive read that this can happen since the TPMS works on bluetooth as does the new stereo.

Ill give Crutchfield a call to see if they have any ideas. Unless someone can tell me how to fix this problem I think we will probably send this stuff back and put the stock radio back in.
