Only one problem,

# 200W x 1 (4 Ω)/ 400W x 1 (2 Ω) (continuous power)
# 400W x 1 (4 Ω)/ 800W x 1 (2 Ω) (max. power)

200WRMS @4 OHMS i need another 150WRMS

But thanks for the suggestion.

Have a look at some JayCar Response stuff...if you're lucky last years models might be on special to make way for the new.

http://www.jaycar.com.au/productView.as ... BCATID=595

More power than you need, but you can always turn the gain down to accomodate the sub. Enough head room for sub upgrade or addition of another sub.

Price is similar to the Pioneer one.

Can't say I have used Response before, but haven't heard anything bad about them so far.

There's not really any point getting a monoblock for a 4 ohm sub... Monoblocks are designed to make their optimal power for 2 and 1 ohm loads. For a 4 ohm load, you're better off getting a 2 channel amp and bridging it. It will run the sub just as well as the mono as long as it's well made amp, plus it can be used for 2 channel duties if you ever change your system.

Or just get a second sub of exact model, size, power rating and run them in parallel.

Late reply on this one, been in melb all week.

If its a dual voice coil you can run it at 2 Ohm, i think this sub is but not sure.

My Subs are run at 2 Ohm and they are 4 Ohm subs, but i have two and run them in parrallel.

If it has dual 4 ohm voice coils then, yes, it can be wired in parallel to be 2 ohm... But the original poster asked for 350W at 4 ohm.

Yeah, but im saying you don't NEED to run it at 4 Ohm. It can be run at 2 Ohm. I mean sure you can run it at 4Ohm, but why? You get less power from most AMP's at 4 Ohm. You mostly only run 4Ohm on speakers that you want to have good quality sound from, and with a sub you wont be able to tell the difference. EG my mono block has 250W RMS @ 4Ohm and 380W RMS @ 2Ohm.

4Ohm will allow more control off the cone...also runs a little cooler so it will last longer if played hard enough. I can see your point though.
