And those specs are still wildly inflated as well.

Have a look at a similar amp.Say a Concept 60w rms x 4 or a Pioneer 60w rms x 4, both have 60 amps of fusing for it. What is the size of the fusing in your 4 channel?

 

I havent got my amp yet. I got it off ebay and its in the shipping process right now

 

I have a bit of experience with Lanzar's products...(i'm building a Lanzar system)
The fusing for that particular amp is 25x2 (50A)

From my experience, lanzar has high and low line products.
These are as follows from lowest to highest

Viberant
Vibe
Heritage
Opti/OptiHC

I would try to stay away from the first two listed

most of the specs are on lanzar.com

 

Based on the (2 x 25) fuse rating and my experience with actually testing amps like Legacy Lanzar, Jensen etc: here's my guess at the true power:

4 x 50 WRMS @ 4 ohm stereo
4 x 100 WRMS @ 2 ohm stereo
2 x 200 WRMS @ 4 ohm bridged

I would say bridge the amp and run each voice coil on a different set of bridged channels. That's assuming the sub can handle 400 WRMS (which is doubtful considering it only claims 1000W peak)

Power the 6 x 9s with your deck.

Don't run the 6 x 9s and the sub all on that amp. I will be weak. The 6 x 9s would only get 50 w each and the sub would only get 100 w. It would have been more beneficial is the sub was a 2 ohm DVC if you wanted to run 3 speakers off one amp.
