Bills willingness to send his amp out for testing speaks volumes about his confidence in his product. At 330watts at 2ohms I would be confident as well!!

 

When I spoke with Bill @ Biketronics before ordering my 4180 I asked him about my speaker setup. BT 7.1's in Front and Infinity Kappa's in the rear pods. I asked him if there was any problem with running 4ohm in front and 2ohm in the rear and he said there was essentially 4 separate amps in the 4180? So basically each speaker could get the full output of the AMP? And there was no problem mixing the 2 separate sets of speakers since again each would have its own amp. Not sure if other amps are like that.. I know very little about audio stuff.

I'm going to wait until I send my HU in to Iron Cross to get the pre-amp outputs installed before I put the 4180 in though. Don't want to tear everything apart until I am ready to do everything.

 

Anyone get to test out the Moto 600.4 yet?

 

Only dude I know running it is Gannicus and he gave it a 5 star review.

 

any updates?

 

Yes Sir. This is a older thread but yeah the Moto 600.4 is a great amp! But the BT4180 is comparable to the Moto 600.4 as well. The only reason I liked the Moto better is the fact that it had gain controls. Both amps are High end amps with excellent power and clarity! If you don't like fooling with gain controls the BT4180 is the ticket. If you are old school like me and like to tune down to a gnats *** you want the Moto 600.4

 

FWIW, here is a topless BT4180. The 4 boards on the left are the 4 separate amps and the large board on the right is the power supply.

 

Spot on! I go through this with so many setup quotes...deciding factor is always if they want a simple plug/play easy amp, or one that allows some adjustment and fine tuning. At this point, I'd say half my setups run one of the 2 amps...
