G2 Sub Wiring

What amp are you gonna use ? i use fane 18xbs in the G Sub & put 1400watts into each cab

Thats even worse then, unless those PD186 drivers are 16 ohm versions?

That Kam KXR1500 amp ain't designed to do 4 ohm bridge, it will break or go into protect soon.

So they are not 16 ohm drivers then?

I'm surpised you haven't broken the Kam KXR1500 yet, as it can't do 4 ohm bridge,I bet it will break very soon when you start to push it in 4 ohm bridge. Anyway since you building G-subs with PD186 drivers, both high quality stuff theres no point skimping on a lousy kam amp. Change the amp. You don't want to be in the middle of your gig when the amp blows up or shuts down. So better to sort it out when your G-subs are built.

The C-mark right at the bottom of this page: http://www.djkit.co.uk/acatalog/Buy_C_Mark_Amplifiers.html It's £395 new and gives 2x 1600w rms into 4 ohms, so you can power both G-subs with that, instead of straining two crappy kam amps in a lower impedance than they can handle which is bound to cause problems in the future.

Theres also the Audiohead AH4000 amp that gives 2x 2000w rms into 4 ohms that you can get on ebay or from Squire.

Last but not least, the T.amp Proline 3000 would power them two G-subs also. It gives 2x 1500w rms into 4 ohms. It gives the least wattage out of the 3 amps I listed, but it can do 2 ohm loads per channel though. http://www.thomann.de/thoiw2_tamp_proline_3000_prodinfo.html
