[fire400]

powering it from my sony deck.
just need an opinion.

=Infinity Reference X REF-9603ix 6"x9" 3-way car speakers
Peak Power: 300 watts
Power Handling, RMS: 100 watts
Nominal Impedance: 3 ohms
Frequency Response: 46Hz-21kHz
Sensitivity (2.83V/1m): 94dB

-OR-

=Infinity Reference 9633cf 6 x 9-Inch 300-Watt High Performance 3-Way Loudspeaker (Pair)
Power Handling, RMS: 100 Watts
Power Handling, Peak: 300 Watts
Sensitivity (2.83V @ 1m): 94dB
Frequency Response: 46Hz - 21kHz
Impedance: 2 Ohms
Mounting Depth: 3-1/16 inches

They're essentially the same speaker I think one is just wired to have a lower nominal impedance.

Should be fine no matter which one you pick. The one with a lower nominal impedance will simply be able to pull more power from your head unit. However, if you're head unit isn't rated for a lower nominal impedance that'd be bad. Most headunits are capable of pulling 2 ohms from a quick google search.

Either one is good. I have the Infinity Kappa's and I love em to death. One of the best purchases I've made. One of the worst has been to not add matching subs. I'll have to get to that one soon.

Edit: Oh, make sure they fit. Check your mounting depths and everything. ACTUALLY CHECK YOURSELF if you want to be sure. My car had a little lip that cut right next to the speaker magnet. It just was a piece producing into the speaker area for no reason. I just cut it off and gave myself more room for a bigger speaker.

Like tential said, check that your Sony headunit can drive those loads.

And don't forget that the max power you can expect is about 25w from a HU amp, and that's on a good day.

25 Watts "SHOULD" be enough for you but I am a HUGE believer in having excess power available. At worst you don't use it. I went with a Soundstream amp. They're not that great of a brand but their reference series got some praise.

EBAY has TONS of audio for sale for less than retail (without warranty of course). All new. I ended up ebaying everything. The only thing that wasn't new was my JL Audio Amp cables. It clearly had been opened before. But it had all of the parts in it so whatever.

There was definitely a difference to me in sound quality/Max Volume level with the Amp included. For the extra 250+ or so I spent it was worth it to me. You can add the amp later down the road too so I'd definitely get one eventually. Read some car audio forums and find a decent price to performance amp.

For Home Theater I thought Emotiva was the only way to go but turns out with some forum hunting, Pro Amps are the best price to performance ratio with Inukes being the best (just need a fan mod to use a Noctua fan. Luckily we're used to PC stuff on here right?). There has to be a similar deal on Car stuff. Just hunt!

Lots of good info so far... in addition 6x9s are usually rear deck speakers. If that's the case in your car, then do not spend too much money on it. If you are interested in making the car stereo sound better and are on a tight budget, look into sealing the area around the speaker to isolate the rear waves from the front. That helps reduce interference (improve sound) and maintains efficiency of the speaker (don't need to turn the volume up as much).

Other cheap ways to improve the sound is putting neoprene in your doors and over your wheel well. Essentially like a neoprene sheet over your vapor wrap. Keeps road noise out and further isolates rear sound waves. All of these helps reduce your noise floor. If you can reduce it 3db that is like doubling your amplifier power.

thx for the input. i think both of the speakers mentioned are essentially the same thing, just a newer revision, one with the grill, one without the grill.

my speakers sink into my trunk and have pretty much unlimited space without limitations to how deep they can sink into.

i was thinking about getting these baffles. but my sony xplod sub is beneath the speakers, and i'm guessing it would rattle the plastic and make things sound terrible, with respect to bass reflex.

i also heard that if we connect the front speaker wiring and the back speaker wiring to both be sent to the back speakers, it would slightly increase power? i am trying to avoid installing a second amp and skip the distributor.

the sony xplod sub is powered by a 2 channel actiontec amp. both hit 1000w max. but i don't ever push it. and i'm not planning and getting high bass rear speakers. i may consider getting a new amp to power all 3 units. i think the sony xplod hits up 700w max.

btw, i have my front speaker wiring disabled because i just want a 2.1, rear speaks+sub.

any thoughts or inputs greatly appreciated.

if anyone can recommend 2.1 amp that be cool, and possibilities of saving my alternator, i hear there is a middle unit that can control over-flow to save from draining the battery too much.

Adding an extra 25 watts will do absolutely nothing for you. It's really not worth it. It's much better to have speakers in front too rather than speakers in back. You could go 2.1 in the front and that'd make sense. But 2.1 in the back really just doesn't make sense with how sound works. Adding 25 watts though isn't going to do anything for you. An amp is needed if you want a difference from having more power.
