Hey Guys.

I just picked one of these up and after an exhaustive researching search I pretty much have the gist of how to hook this thing up.

One question though - no where in what I read did I see a detailed explanation for where to hook-up the 12V power wire. It's only a 14 gauge wire comming out of the amp so would it be alright to just tap into the power outlet under the glove box/secrete compartment, or do I need to run it all the way up to the battery?

Thanks for your help.
Cheers.

 

You do not need to wire the power to the battery, you should wire the Bose Sub's Power to the HU's Switch Ignition Input (White/Red) or Antenna Amplifier (Yellow/Green). This way you will turn off the Bose sub whenever you turn off the HU.

 

The amp won't draw too much power to cause any problems?

 

I'd recommend against using the ignition input or antenna amp leads from the HU. These were not designed to supply much current.

I don't know how much power the Bose sub puts out, if anyone knows, that would really help to determine if you need to wire to the battery.

 

OK, so again, would the power outlet under the glove box/secrete compartement work? (I believe it's 12V)

 

That rsx sub has a signal and power wire. The signal wire to latch the realy for the amp in the sub is fine to connect to the HU accessory. But the power wire should be connected to an unused 12v source.

I believe it only puts out 20W. It's not much actually.

 

What size fuse is used for the accessory outlet (I'm at work and can't check right now)?

If it is a 10A fuse, and we conservatively say it is 12 volts, it will support up to 120 watts.

If we assume 50% efficiency for the Bose amp and it puts out 20 watts (sounds a little low to me), that means it draws 3.3 amps (or 40 watts) (P=I*V).

If it puts out 50 watts, it uses about 100 watts, so that would be a current draw of 8.3 A.

So, if the acessory outlet is fused with a 5 amp fuse, I wouldn't use it. If it is 10 or 15A you should be OK (unless the Bose sub is more powerful than we assumed).

You can run the signal wire to the antenna lead of the HU.

Clear as mud?

 

My Bose sub power wire was connected to the HU's Switch Ignition Input (White/Red). I had no problem at all after about 2 months
The maximum power rating of the amp inside the Bose Sub is 100 W, but I think the RMS is no more than 20W to 25W.

 

Ya it's either 20 or 30W RMS...

It's very small. It's only a 5 1/4" driver. Or maybe 6.5". It's been a while since I've had my RSX.

 

I put a relay switch between the constant from the HU and the amp.
