Woofer Advice

[A1cntrler]

Not having to do with the Sport Trac, but Ford... Anyways



I have a car that I am restoring back to stock, to include the original audio system. It is a 1990 Anniversary edition Thunderbird SC. This car came with the premimum JBL sound system, to include a subwoofer in a box in the trunk. The original speaker (paper cone and foam surround) has seen better days (i.e. no longer works) I need to keep the original sub box, but am not opposed to opening it up and putting in a new woofer. It will hold a 6.5" woofer. The amp is rated at 75w/6ohms. The closest replacement I can find is a JL 6w0 speaker, but it is available in 4 ohms or 8 ohms... Which one do I need to get. I am illeterate when it comes to ohms...



Airspace for the factory box works out to be about .27 or so I am told..

If I had to guess I would say the 4 ohm, but it depends on the amp that is pushing it.

Somehow I figured you would be the first to respond... The only specs I can get from the factory amp is that it is 75watts and put out 6 ohms. Why would the 4 be better?? What would happen with the 8ohm speaker on it??

You might also consider one of these, they are supposed to be pretty damn good for the price.

Oh it's it's 75 @ 6 then you might need to run the 8. If you run a sub with lower impedance you will more than likely overheat the amp as it will be working too hard. It will however be putting out more power.

That is the kind of answer I was looking for Jacob. .Thanks. I wanted to know why.

I missed the amp rating in the first post, thats why it took so many to get you the answer
