i recently purchased a carver av-405 amp here are the specs

> Rated Full Power Bandwidth 20-20kHz
> Center channel power 110W
> Surround power/channel 50W
> Stereo Power (L/R front) 150W
> 4 ohm Continuous Power/Channel (L/R front)
> 150W
> THD at 1kHz <0.05%
> Input Impedance (Line) 39 kohms
> Input Sensitivity (L/R front) 1V
> Gain 29dB
> S/N A-weighted, ref. to rated power >95dB
> Power Consumption at full power 775W
> Dimensions without handles 4.4x17x13.7
> Net Weight 30 lbs.
> Shipping Weight 35 lbs.

i have two sets of main speakers, rt100i w/ rt35i stacked on top (upside down) should i wire them parallel to get a 4 ohm load or sould i wire th rt100i's off the amp and the rt35i's off my yamaha
if i wire them parallel is that going to give me more or less power?
Any input would help?
Thanks

Toshiba 51h83 HDTV
Yamaha HTR-5660

Pioneer DV-578A-S

RT1000i's
RT35i's

    If you wire them parallel to the same speaker outs on the amp, the amp will have to work harder to power them. You'll probably get better volume and less strain if you wire one speaker pair to the receiver's amp. Since the amps wattage rating only goes up to 150 from 100, instead of 200, it might not be ideal for a 4-ohm load with another set of large drivers.

    No disagreement with what Whadyasay states in general, but will comment that Carvers have decent current capabilities which is really what 4-ohm loads tax. The fact that your mains output is upped by 50% is one indicator of this (lesser amps would only rise 20% or so; many rise only this much at the now common 6-ohm alternate load specs). Also consider that Carver amp designs typically have 1.5 to 2 dB of headroom (AKA short-term power) reflecting additional current capability.

    I'd have no fear of at least trying the front stage in parallel off of it. Depending upon your listening levels, it may do just fine, if not, the amp will go into protection mode. Not something you want to make a habit of doing, but as a trial... no biggie.

    Will be interested in seeing what you find.
    More later,
