I'm looking into buying Infinity Reference 6 1/2" components. I have a Pioneer amp that is rated at 35 x 2 at 4-ohm or 50x2 at 2 ohm stereo. Is it possible to wire the components 2-ohm? The components sets include a seperate crossover, but I'm not sure if it is set up for bi-amp.

Thanks for the help!

 

When it comes to impedance, you're basically stuck with the hand you're dealt. There are a couple brands that make 2 ohm components (Orion comes to mind), but there's really no way to change what you've got. Some brands make dummy loads that can drop the overall impedance, but they suck up all of the additional power, so they make no difference overall.

The only reasonable way to get your impedance down is to parallel another pair of components in.

BUT.... 35 to 50 watts is a barely noticable difference. 35 watts is still plenty to get real loud as long as you filter the bass out of the signal.

 

Thanks for the info. I'll just leave it 4-ohm then. I'm hoping there will be a noticeable SQ change from the HU amp. I have an Alpine with the V-Drive 60x4, which is 27x4 RMS I think. So on paper I'm only gaining 8 watts with the Pioneer, but it should be cleaner power. That's the theory, anyway.

Oh yeah- and I'll be using the amp's 80 hz HP crossover.

 

infinity components sound awesome, even off a headunit.. a friend of mine has some running of a kenwood excelon deck, 22 watts per channel, and it sounds great.. amplified, they should be even more spectacular.. he has more bass than some people i know with subs in their car... and btw, i thought the speakers had built in crossovers.. so you wouldnt need to worry about setting it on the amp i dont think.. could be wrong tho..

 

For the most part, switching head units isn't going to do anything. Head units can only get so powerful, and they're all about the same regardless of what they advertise.

 

The Pioneer I'm referring to is actually a dedicated power amp, not a head unit. So from what I've read, I should be getting "cleaner" amplification from a dedicated power amp; even at a somewhat low power rating of 35x2. (Low compared to, say, 100x2)

Either way, I'll be good. I never listen to my stereo loud enough to hear audible distortion. And I'm not competing or anything.

The Infinitys have seperate crossovers for HP/LP between the woofer and tweeter at 3500 hz, I think. They don't have a built in HP at 80 hz to filter out the bass though. But I've got HP on the Pioneer amp and on the Alpine HU.

Thanks again for the help!

 

Sorry, I misunderstood from the last post. Yeah, a dedicated 35x4 amp will provide substantially more power than any head unit.
