Ohms question for JL 8W6 speakers (2)

[aharper 10+ year member]

I found a good deal on a couple 8w6 JL subs and was doing a little reading.

The 8W6 is rated at 6 ohms. If I have two of them, how do I wire them to get to either 4 or 2 ohms, the standard for most amplifiers? I am hoping not spend more than $200 or so on an amp and most of them run at 2 or 4 ohms.

If I wire the coils and speakers in parallel it produces 1.5 ohms. If I wire the coils and speakers in series it produces a 12 ohm load.

So what is the best way to wire the speakers? If I have an amp running at 2 ohms will it damage the speakers by being off .5 ohms??

TIA

no...if your subs are wired to 1.5 ohms, the amp will run at 1.5 ohms, just make sure you have an amp that can handle a load

So what amps run at less than 2 ohms?

Class D monoblock amps, do you have an amp yet?

No. I held off getting an amp waiting to see what subs I ended up with. I used to have 3 8w6's some time ago (years ago) that ran at 4 ohm, probably won't end up with 3 in this case, only 2. Found a decent deal and think I'm going to go for it.

So now I'm finding myself looking for a 1 ohm amp. A quick search through the classifieds and it looks like there are plenty to find.

SVC6 or DVC6?

Single 6's will be 3 ohm but dual 6's could be 1.5 ohm

No.

Two single voice coil 6ohm subs can only be wired to 3 or 12ohms.

And you can not run an amp at a different ohm load than your speakers are wired for. A amp reads it's load from the speakers. So if you wire your speakers to 3ohms the amp sees 3ohms.

8w6 is a Dual Voice Coil speaker, so dual 6 ohm.

Reading the spec sheet for two speakers it reads like this...

With coils AND speakers wired in parallel:

2 dual 6Ω speakers (D6) will present a 1.5Ω load.

With the coils wired in series and the speakers wired in parallel:

2 dual 6Ω speakers (D6) will present a 6Ω load.

So I guess I mis-spoke in my original post. I can't find an amp that runs at 1.5Ω so do I look for a 1Ω amp or a 2Ω amp????????

Or... it looks like a JL 500/1 should run 400 watts at 1.5Ω. Is that right? If so, then I could certainly go that route.

look for a 1ohm stable amp

Yes, the JL 500/1 will run them nicely. You will see 500w RMS between 1.5 and 4 ohm. Also the JBL crown series will do that.

I think the 500/1 and 2 8w6's would be a nice combo.

I agree the jl audio 500/1 would be an excellant choice in amplifiers for you 2 8w6's.
