Ok first of I just don't understand nothing about ohms stuff on amp and subs. I've read and read but the more I read the more confusing I get. Anyways to keep things short here's my problem. I have 3 12" Rockford hx2 that I'm tryingbto wire up to a lanzar vct2619 amp. The amp is 6000w and I just want to wire up my subs to be safe and not fry anything up but at the same time get the most out of it too. Anyone with any suggestions. Remember I don't know Jack about this so just make things easy for me (explanation). Thanks guys.

What is the lowest safe operating impedance of your amplifier? Are the speakers single or dual voice coil? What is the impedance of the coil(s)?

My subs are dvc. As far as the impedence I have Bo idea that's why I'm on here. I'll tell you guys the subs I'm using and amp and hopefully you guys can help me out. I'm sure you can google it or something. Sorry for being such a newbie.

Is the model number HX2 RFD2212?

Found the driver specs. They only came in dual 4ohm. So you have a couple of options.

Better for longevity of the amp and also the subs.

Best wire config for full power.

After looking at the specs of that amp, I am guessing that the part stating that it is 2 ohm mono stable is a misprint. The amp is 2 ohm stable, 2 ohms per channel. NOT 2 ohm mono. As J already stated, for amp longevity, use the top diagram and I suggest ONLY the top diagram.

Is there a secret hidden in these ratings that I cant see?

BRAND NEW Lanzar VCT2610 6000 WATTS 2 Channel High Power MOSFET Amplifier
# 3000W x 2 Output at 4 Ohms
# 6000W x 1 Bridged Output at 2 Ohms 2 Ohm Stable

Lanzar above the LAW? If the bridged channels are stable at 2ohm, does 1 ohm stereo automatically become my minimum rating? IF the 6Kw_@_2ohm is delivered in bridged mode, then 4ohm stereo is actually only 1500w x 2ch. Buuut if the 3Kw_@_4ohm delivers in stereo, then mathematically I'll be expecting 12Kw_@_2ohm on my mono channel! This looks like a mono amp's ratings written backwards. If your still with me, I just need to know if this is a typo or a joke!

Ok so I'm assuming wiring it for a 6ohm then. I just want to be safe and not mess anything up but at the same time get the most out of it too. Can I wire it up in paralerell?

I looked 3 different places. There Joke rating is posted that way all 3 places i checked. you would think it has to be a misprint, BUT.......

This is straight from lanzar's web site. They are claiming the same thing.

I completely agree. I would wire at 6ohm. It is the ONLY safe option. I paid no attention to the numbers just focused on "2ohm stable bridged". It has to be a 4ohm stable bridged amp. Funny though it is even printed this way on the Lanzar's website. Makes me wonder what they are thinking lol. We wont even go into fuse ratings. This also is not the only VCT line 2 channel amp rated/misprinted in a similar way.

MODEL: VCT2010

400W x 2 Output at 4 Ohms
800W x 1 Bridged Output at 2 Ohms
2 Ohm Stable

This one is actually correct.

Seems to me they are trying to pull some shananagins! most of the VCT line is rated in this misprint. One hell of a misprint? Or do they really think they have broken Ohms LAW?! Just hoping we would not see? Also these are all pulled from the Lanzar website and also backed on net sales information for these amps. https://www.lanzar.com/search2.asp They might want to fix it lol.
