500wrms @ .5ohm?

[Rideredder 10+ year member]

My friend wants to buy my 5 ED EHQS 8's. They are all single 2ohm. According to JL Audio's website, the can be wired in parallel to .4ohms.

Is this a dumb idea, or can anyone recommend an amp that will do 500wrms at .4ohms?

He will have them sealed in the back of his PT Cruiser.

Soundstream Reference 500 used on ebay.

"2 x 250W @ 1 or ½ ohm"

How would you wire it at this setting?

I wouldn't run a Soundstream Reference S series @ .5 ohms mono for daily use. The S and SX series was notorious for having issues with their auto switching circuitry (High power versus High Current) and even the manual states that you shouldn't run it lower than 1 ohm mono or 1/2 ohm stereo. Good luck running 5 woofers @ 1/2 ohm stereo //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

The next problem is finding an amp that will take .5 ohms daily yet only produces 500 watts RMS. If you can find an old Orion HCCA 225 or 250 with a bridging module, you might be able to get away with it. I remember seeing some of those running at a 1/4 ohm mono back in the day. The only down side is after 15 minutes of pounding on them, you can grill hot dogs on the heat sink.

I have ran a 500s daily @ .5 for years. You are correct about the S and SX issues. If you can find a Original ref 500 you will be fine if you ask me.

dont run 5, thats retarded, just dont do it

Run 4 and keep a spare,

Why not run them in series and run them at 2 ohms?

4 SINGLE 2 ohm subs can be ran at 2 ohm??

 

[alex5857 10+ year member]

Yes...Just wire ear pair together to 4ohms and then bridge the two pairs on the amp to get 2ohm.

dont know if that came out how i pictured it.

there is no way to equally distribute a series wiring into 5 svc woofers

its either .4 ohms or 10 ohms.

your best bet is to just go with 4 woofer

Can someone show me a diagram of this in series, or series parallel? JL's website shows 4 woofers in parallel to .5ohms. I can't find any series diagrams.

try each pair in series then wire those in parallel? Just a thought, i could be wrong

OR wire each pair parallel then series the final connection Even though your method is the "preferred" way.
