How to wire a speaker?

[Tom]

Got a bit of a strange question.

I hope I posted this in the right section???

I will be installing a small sound system for my car so I can listen to the music as it should be heard and have come across this subwoofer. It's got 4+4+4+4 ohm. How would you wire that up???.

We need more information, I think.
How many drivers in this cabinet? Possibly 4, although there could be two with dual voice coils.

Have a look and let us know what you've found out.

Hello Andy,

The cab would have two of these drivers and they are rated at 500 rms each.

The speakers have 4 voice coils from what I can from the picture and infomation provided as it is an Italian driver. lol

This is only an educated guess, but I'd suggest two pairs in series, ie
4+4=8ohms. Then those in parallel, 1/8+1/8=1/4, ie 4ohms.

Thanks for that Peter. I was thinking that but wasnt to sure if it would work or not?

So how would I go about wiring 8 voice coils up then. lol.

I would double check they are 500 watts rms. As most car audio systes are prone to inflation. I bought 2 15 inch cones supposed 500 watts rms at 4 ohms . Turned out to be 100 watts rms and 500 sound power (not music power) And was only 50 watts rms at 8 ohms or some such.
A lot of incar amps can run at 2 ohms as well so may be worth checking carefully.

I have checked. They are 500 rms each and 1000w max power.

If you click here and then go to page 2 then select the CSW4000, under that you will see a PDF, click on that then the stats.

That might clear things up instead.

I do hope there aren't any audiophiles lurking, or you're in for a rollocking!

That would be exactly how I'd interpret it, seems the only logical way to arrive at 4 ohms combined.

I hope there are. Any advice on this would help me a lot. I will be installing an EQ in there aswell to try and get a flat sound. Some of you may think I'm mad or don't see the point but hey.

As for the ohms, thats two people saying the same thing. As already posted, just need to find out how to wire it all up. lol

Tom, a thought occurs. If you got a big inverter, to give 240v from a car battery, you could put the Mackies on the parcel shelf.
