I have an aftermarket amp/sub and no use for the shaker 500 door speakers, so im wondering that if my radar detector has an audio out plug, could I run a audio cable from my radar detector *2.5mm to 3.5mm, 3.5mm to rca, rca to shaker 500 rca inputs and leave the shaker amp turn on wire connected. My theory is that the radar detector alerts would play through the 2 door front door speakers when it makes alert noises. Also my headunit has a tele mute wire, that will mute the sound of the radio while it receives a negative ground. maybe I could tap a ground from somewhere on the radar to use that function as well?

 

it would as long as you had that input selected on the radio. The downside is that you would not be able to listen to music while waiting for the detector to go off, but the plus side is you can then amp your detector which is just wicked....

I have not seen a radar detector with headphone unless it was made for bikes, nor do they have the telephone mute.

 

Unsure how well it would work, as they´re subs and a certain frequency range is set to pass... Not sure how well that´d sound if it got through at all from the normal high-pitched alert tones given.

The mute line.. Unlikely there is a switching ground on a positive radar alert signal even on the board if you ripped the detector apart. There is likely a 2.5v, 5v, and/or 12v signal switched when an alert is triggered however. So you could use a simple relay to switch to ground when triggered so you could mute the radio automatically.

Be a bit of a PITA though, you´d have to delicately probe while it was on the bench, powered, and have something that can generate a [false] alert.

 

not sure your understanding correctly, the radar detector is going to be plugged into the shaker 500 door speakers which have their own rca inputs and amp remote wire meaning the remote wire would have the speakers cut on with the radio but wouldn't be getting there input from the radio. basically the 2 front door speakers would only play the radar detector sounds and no sounds from the radio. and yeah my radar detector has a mini 2.5mm audio output.

 

i was worried about the frequency range of the speakers to but when they are hooked up to normal outputs on my radio they do mids very well. Do you know for certain if the speakers have their own eq in line with the stock amps, or was that controlled by the stock headunit?

 

Unsure what is doing the filtering. Amps, or HU. Likely oldschoolfool or someone else that can chime in later would know.

If it´s just the HU, then ya, whatever the limitation of the speakers themselves would just be at issue.

 

if yer willing to donate 2 speaker to it, I guess it could work but the real question is why......

 

I believe the head unit does the filtering as tested here: http://www.mobilesoundscience.com/f2...stem-test-231/

On the other hand, my limited experience with Mazda and Ford amplified subwoofer systems revealed a weird phasing issue with the factory amplifiers. I had the toughest time integrating them with aftermarket subwoofers because I always encountered cancellation in the 50 to 100 Hz range. Reversing the phase on the aftermarket subwoofer did little to correct cancellation issue, so I figured the factory amplifier is phased somewhere between 0 and 180 degrees.

 

Very nice idea. It would work.

I currently use my door subs, but a small tweeter mounted on the drivers side with its own tiny amp would work. It could all be cheap used stuff. A crappy pair of tweets for $20 and an equally cheap/crappy amp pushing 25wrms would do the trick.
