8ohm plate amp needed

[solidcrowd 10+ year member]

Looking for around 300-500rms @ 8ohms for 4 ehqs8s going in a 8.22 cuft. sonotub tuned to about 25hz. How much is this going to cost me? I'm not looking to spend to much. I found this amp but never heard of the company, but then again I am a newb to home audio.

Can you arrange the subs so that you have a lower impedance?

umm I have 4 s2s, can I do anything other than 8ohm?

I am guessing you are saying that they are all single 2 right?

If so you could wire them two in parallel and put that in series with the other two in parallel which would give you 2 ohms. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

lol nice, thats deff going to save me some money. I made a thread in the wiring section and they said i could only wire them 8ohms. Maybe they were confused

Maybe they were confused

Or idiots, on this board that's a much more likely scenario.

have any suggestions on an amp for my setup ?

Crown stereo amp, built two Sonotubes and have stereo subbass //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Indeed...

Do you have a budget?

Check out Parts Express, they might have something to your liking..

I like the stereo part...

But would change the amplifier... //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

ehh probably under $150, going back to pe to check out what they have a 2ohms, since all I was looking for was an 8ohm amp, o and by the way is this diagram i made right?

More like this...

What you are doing is running everything in parallel. Which makes the impedance .5 ohms.

What you should do is put the pairs of drivers in parallel, which gives you 1 ohms each. Then series the two pairs giving you 2 ohms final.

Wow...thanks to JimJ, it seems like this subforum has renewed enthusiasm.
