need advice: bridge 4x6 or 6x9?

I have a 4 channel amp that can be bridged into 2 that I am going to put into my system. However, I don't know which speakers to hook up, my 6x9's or my 4x6's. The 4x6's are higher quality but probably require less power than the 6x9's. What differences should I excpect? Any suggestions on which way to go? Thanks.

Why don't you leave it in 4 ch mode and hook it up to all 4 speakers?

I was thinking about that, but it's not an extremely powerful amp (Clarion Pro Audio 5/4/3 channel). With 4 mid/high channels going it'll give me 35w RMS per. I bought it because I used to have an Alpine in-dash disc changer that had no interal amplifier. However, I'm picking up a deck that puts out 25w RMS and now I'm trying to decide if it would be worth it to lose 10w per channel on one pair in order to give the other pair a real power boost.

That said, in a little while this may not even be an issue because I'm pretty close to picking up a set of DJSexay's kickpanels and putting in a pair of 6.5" mids. If I buy them, I'll put both the 4x6's and the 6x9's on the deck amp and bridge the Clarion amp for the 6.5's.

the 35 watts the amp puts out is cleaner than the 25 the deck puts out (more like 10) the amp will give you better sound all around then the deck.

That 25 watts from the head unit is actually probably closer to or less than 10 watts RMS. And 35 real RMS watts should be enought for mids/highs. I vote for running it 4 channels.

The RMS on the deck would seriously be more than 15 watts below the specs?!? I mean, I'm not saying the deck has a peak of 25w, it has a peak of 40w. I had no idea that they would run so low... how can the audio companies justify their RMS ratings if they are nowhere near the actual operating levels??

Well it may be a little higher if it's advertised at 40 Max...I thought you meant it was advertised at 25 Max. It may be close to 20 RMS if it's a good name. It's usually a little less than half Max or so. They use all kind of tricks, like running each channel seperatly to get the total power reading, instead of running all the channels at once, because the power supply is one of the large bottlenecks in head units.

Tricky b*st*rds...

Anyway, the deck is a Fosgate RFX8350 that Crutchfied's specs rated at something like 22 or 25w per channel RMS. But, like you said, if they're allowed to assign that number based on the performance of one channel at a time...

That's plenty of power for coax speakers. Like everybody else is saying, 35 watts from an amp is totally different than "35" watts from a deck. I'm using a Pioneer 4x30 amp to power my 4x6" plates and a 10" sub. Not nearly enough power for the sub, but the 4x6s have as much as they can handle.
