New deck but...

[Camaro69]

Hi I'm new here and need a bit of help.

I just got my new Pioneer DEH-590IB deck today. The instructions say that it "should" not be used with speakers below 4 ohms.

I'm using 5.25 Infinity Reference components 5022cs up front with the same 2 way 6x9's 9622i out back. Both these speakers are rated at 2.65 ohms.

Should I be OK? I found this about the new speakers below...

Infinity also created the new Reference series with 2 ohm voicecoils rather than a standard 4-ohm. The impedance rating of the amplifier or head unit is a rating of the impedance of the load connected to its output terminals. That load includes the impedance of the speaker, the impedance of any passive crossover and the resistance of the wire that connects the speaker to the amp or head unit. The factory-installed wire in a car is tiny and contributes a significant amount of resistance. The load that your four-ohm-rated head unit will see with Reference speakers is much closer to the optimum load than it would be with a 4-ohm speaker. A 2 ohm coil extracts more power from your radio or outboard amplifier, safely maximizing your sound.

You should be alright. I have run a few older decks at 2ohms and they have been fine. You should really look into a new amp for your mids/highs in the future.

Ok thanks,

I just noticed on the the box a picture of a deck with a 4 ohm approved sticker beside it. So I guess i'm OK.

What amp should I be looking at, 2ch or 4ch, 50x4 or 100x4 or?

I don't anything too extreme just something basic.
