Bi-amp HELP and ADVICE please!?

[BigE-Dadda]

Gear: Onkyo TX NR818, Onkyo M-505o 75w x2 ch, Polk 75T LR in question.

I have read so many conflicting statements regarding this topic and I'm new to the whole Bi-amping idea, but need some good advice on how to or not to? That said with 818 I'm capable of bi amping from unit but will lose 2 and 3 zone capability and other channels SB, FW, which I don't use anyway. I'm using FH though. The configuration option on 818 are confusing. In menu I choose to Bi amp from 818 I loose Zones 2 and 3 and pre out to external amp. I want to use the M-5050 only to Bi amp my LR along with the LR in the 818 to give me more juice to open up the fronts bc I'm probably only sending 100w (when the can handle 300w)to them from the 818 alone bc of the 7.1 set up I have. IS THERE A WAY TO DO THIS without loosing my zones and juice coming from my 818 to the LR fronts? I need my zone capability for my patio and dining. I don't care about the FW and SB. could you all please help me out? I'm at a complete loss here. I bought the m-5050 to add watts just to the fronts so I could keep my zones. Thanks in advance for any constructive help!

Power handling is a maximum rating before something fries and has nothing to do with how much power you actually need. Just use the amp for the mains now and if you don't hear any strain then biamping won't do anything for you. Polk monitors aren't going to "open up" with more power. Taking an ax to them is the best way to do that.

Thx L Garcia. So you mean use the 5050 on LR instead of the LR of the 818? I was thinking of that but how do I wire it that way? And in settings? I'm assuming just connect RCA to LR from amp to LR 818 and run speaker wires out of the Amp? What about the external amp pre- out ? I'm very new to adding amps to channels etc, even though I've been an enthusiast for 20 yrs.

What is your system lacking with the 100w?

Your fronts are going to be crossed around 80-100 rite? bi amping will not help anything, if you want more power up front get a larger amp, but make sure you need it before you spend the money.... what speakers do you have?

Thanks for the kind response ImcLoud! They are Polk 75t that I got on sale for 150$ each. I know how some feel about these "low end" types and feel the need to down some one for not blowing 2k on fronts. I have them at full range now with front heights as well.

It's really not lacking I suppose I just wanted to see what it would sound like if I put more power to them either Bi-amped or using the amp to get possibly better sound?? I dont know. I'm very new to adding amps etc.. And am just looking for advice and help!

Speakers are the most important factor in your system's sound. If you are trying to improve your sound, new speakers are where you should spend money, not amps. You don't need to spend anywhere near $2K for mains to get really good sound either... The Polks are easy to drive, so unless you are looking for deafening levels, an amp isn't going to "improve" them. Amps basically allow you to turn things up louder before you hear distortion; they will not make your speakers sound better than they are - this is a common misconception. Since you already have the amp, you would connect it to the preamp outputs from the receiver and then plug the speakers into the amp, but as mentioned, if you weren't hearing distortion already at the levels you listen at, the amp isn't going to help. When people say a speaker "opened up" with an amp, that is an indication they did not have sufficient amplifier power previously.
