I know there are several types of relay and relay boxes out there. Some are super cheap and some uber expensive. What type of relays are people using to turn on amps/processors/accessories? Starting to lay out an amp rack for my son and will use some form of relay for the two amps and processor in his hatch.

Is something like a relay box from a company like Sparked Innovations complete overkill?

 

[miniSQ]

seems like wicked overkill. Bosch relays do the same thing for $2

sure, it might be overkill, however i use the smaller relay box from Sparked Innovations and love it. more specifically, i have the RBX-LITE four-channel relay box. super quick/easy to install. now if i was only turning on a couple of amplifiers and no other accessory, i would probably have saved the coin and stuck with a traditional Bosch type relay. i also have a standard rocker switch on each of the 4 outputs to turn on/off any combination of my 4 amplifiers when i'm in the mood to tune and/or experiment. relay box or Bosch relay = same end result, just a matter of preference. that's my $0.02.

i am looking at relays that can be timed for on/off timing/sequencing so you can tune in on/off delay times if you need/like to. search "12V Timed Relay" on amazon, they are ~$2-$20 ea. i cannot recc a specific relay per se, but this is an example. seems like a cool added feature. you can add few seconds of delay up to hours.... depending on the relay.

for example, if you wanted to guarantee you turn on/off your processor before your amp or something like that.

If you buy a relay board like that, buy a real TE or Omron relay from digikey and swap it. The songle relays on most Chinese PCB are junk.

Every Songle one? HiLetgo!

Too bad Phoenix Gold doesn't still make the Titanium DD10 distribution center...

Ok time to post up my beloved dd10, if you know you know. Couple light blemishes in the face but nothing bad.

I'm not sure what exactly you are trying to do with the relay(s)?

But if it is just to turn on multiple amps and/or your DSP in the system, refer to the YouTube video by Barevids that was posted above.

But if you do want to use standard relays for turn-on purposes, make sure they have a built-in "quenching" diode for back-EMF, or add one to the relay. There's good info on this in the old www.bcae1.com site under "relays"

You can also do A LOT of cool stuff with a PAC Audio TR7...and other PAC modules.

If I remember correctly you can buy relays with the diode already wired in. I am also looking up what the tr7 can do if used as a relay

This is what I use:

Includes the protective diode you need, and only $2.24 each.
You're welcome

Thank you. Do you prefer relay coil with parallel resistor or diode? Why do you choose the one you do?

Also digi key does have $10 shipping charge.

To add to this it seems like they are on sale at Sparked's site for $52.50

The coil current pull on that relay is 100mA

The Pioneer DEX- P99RS has a max rating of 300mA for the remote on
The Pioneer AVH-W4500NEX has a max rating of 300mA for the remote on
The Pioneer Floating screens has a max rating of 300mA for the remote on
The Kenwood DDX9907XR has a max rating of 200mA for the remote on
The Current models Kenwood excelon units have a max rating of 200mA for the remote on

Do you really need any relays to turn on your amps? If your amps needs a delay turn on, use the remote out from your DSP.

Lol, maybe you should have replied to the person I quoted. i just posted that it was on sale and you seemed like it hurt your feelings.

I grabbed one since its on sale.

 

[JohnnyOhh]

i'd be curious to see what kind of relays they use in it. they probably have the coil flyback control built in them already?

Relax wizzi no feelings hurt, the quote was meant for "InkedAudio".

I think many of the automotive relays are closer to 140 milliamps.

Personally I use solid state now after the power on output stage on my DSP fried after using conventional 12v relay.

Far lower trigger current and no chance of spikes that you can get from coils on conventional relays.
