SWS-8 Shortage?

ChrisR750 · 10-02-2009, 07:33 AM

Read below...according to Earthquake, there is a shortage of 4-Ohm SWS-8's out there right now.

Chris,

We are totally out of the SWS8X (4 ohm version)for another 2 weeks. The only one we have right now is the SWS8XI ( 2 ohm version). We are having a huge demand from BMW owners.

They said I can use 2 ohm as long as they are wired in series...my question is, what is the factory setup? Parallel? If so, can I just pull the factory wiring off one sub or the other and just run a wire from the existing sub so that they will then be in series? And will that affect performance?

Are you talking about wiring the two drivers off of factory amplification? Or a new amplifier? If so, what amplifier?

Depending on the aftermarket amp, you might need to series, you might be OK in parallel.

For the factory amp, I think you would be fine wiring normally, because the OE are "2 ohm", but I don't have any faith that they would sound acceptable to me.

BTW, shortage just means "we ran out and we have a 60-day lead time to make more".

Right on...just wanted to order now and didn't want to get something that won't work. I have an Alpine mono amp that's good for 500 @ 2 Ohms or 300 @ 4ohms so either way it should be plenty of power. So I was thinking it may be better to wire them in series anyways to get more power. Thoughts?

You don't have a choice.

Two 2 Ohm voice coils on a single channel are either wired parallel for 1 Ohm or series for 4 ohms.

The Alpine mono amp is not rated for 1 Ohm operation. It will shut down due to its low-impedance protection being triggered.

So wire them in series. You will not get more power, but it will be plenty.

I just finished an install with 2 2ohm sws8's wired in series with a JL audio 900/5 amp and I am very pleased with the result.

If it were me I would wait for the subs you actually want to be available.
It would be a shame to go through the install and purchase to do it again.
(I have the 2 ohm version running with a low power stereo amp.)
