Help needed...

I am currently running 1 x 12" JL W3 and I am thinking of having a second.
I have also managed to get my hands on a JBL GTO 6000 Amp and so was wondering if this would be powerful enough to run both subs.

Also does anyone know a good place I can get another 12" JL W3 plus a double box?

That's the 6 channel amp right? Or do you mean the GTO 601.1?

The 6 channel amp puts out 75W RMS per channel for the subs. Just by themselves they are not enough to power the 12W3, which are rated at 200W RMS. I have the same subs but I'm running 2 2-channel JBL GTO 75.2, each bridged to power a sub at 150W RMS. Just about enough.

If you're keeping the single 12W3, you can bridge the 2 sub channels from the 6000 to yield 150W RMS. 2 12W3s, the amp will not cope.

Also, which 12W3 do you have? V2 or V4? The JBL GTO 6000 are rated at 4 ohms. If your JLs are rated at 2 ohms, you need to parallel link the terminals to yield 4 ohms or your amp will not be able to handle the 2 ohm impedance on your sub.

However, if you're referring to the GTO 601.1 (580W X 1), then one amp will be enough to power both subs, but still at 4 ohms.

JL Audio product prices in the UK are closely controlled by BBG, so it's pretty standardized where you go. You may pick up some good deals from ebay but BBG will not honour the warranty on these products, so warranty has to be dealt with directly with the supplier. However, looking at ebay prices, it's worth a go as amps and speaker are considerably cheaper than retail, sometimes up to £150!

Alternatively, speak to Andy of Ice Cold.

Cheers for that. How do I tell which version amp I have?

It says on the front GTO6000 1100W, 6/5/4/3 channel power amplifier

6 / 5 / 4 / 3 Channel Amplifier, 1100Watts Max,
50W x 4 + 2 x 75W @ 4 Ohms,
75W x 4 + 2 x125W @ 2 Ohms,
150W x 2 + 250W Bridged

If youve got the W3v2 - d2 (Dual 2 ohms) then youll have to wire the coils in parralell and the subs in series to total a 2 ohm load which according to the jbl site the sub is stable at to achieve 150rms into both subs. Otherwise if their 4 ohm (W3v2 - d4) i assume you wire the coils in parralel aswell as the two subs to total a 2 ohm load.

Either way id suggest getting a better amp for the subs since its often not a good idea pumping half the rms into a sub for any long period of time. The subs will be alot more happier with 300rms a piece which their rated at.
