Product Reviews For Infinity Kappa 63.7i

  • 6 Words-These Are The Best Speakers Ever! They Hit every high note with ease and the lows are punchy! not the best bass but for a 6.5" they have more bass than most, but if you get them you'll need a seperate amp because they have a 2 ohm impedance. most definately one of the best car audio purchases i've made! ever!

  • These speakers are simply amazing. I have these paired with Infinity Kappa 63.7i speakers to a Sony CDX-M8805X Head Unit in my 2004 Jeep Wrangler. It is a concert hall on 33s.

  • I have these speakers hooked up to an Orion 300watt amp and they scream! If loud and clear is what your looking for then look no further! Extremely clear highs but the bass does lack a bit... you have to remember though that these are 6.5" speakers and are not going to blow you away with their bass response. They WILL blow you away with how loud and clear they are. Match these up with a sub and an amplifier giving them the juice they need and you will instantly have a concert hall in your vehicle. 300watts RMS is a little overkill. They would probably sound very nice with 200. I can't even turn the amp gain past half way on my amplifier because my ears just can't handle how loud these things are! Great price on a great set of speakers.

  • Outstanding speakers. I put these in my 2002 GMC sierra 1500 and regret not getting them the day i purchased the truck. These are crystal clear. I listen to everything from country to rock to classic rock to acoustic and they are just awesome speakers. I think with the addition of a bass tube they would be mind blowingly good.

  • I have these 63.7i in the front and 6022i in the back powered by an mrp-f250 at about 50 watts RMS. These are probably the best speakers I've ever bought. I can turn them up so high and the sound comes out clear and without distortion. Do not hesitate in buying these.

  • I have the 63.7i's in the front and the 63.9i in the back of my jeep. Hooked up to a pdx 4.100, they will make your ears hurt... and they have exelent sound quality even at high volume!
