about 8 years ago i bought the Infinity Kappa 5.25 components,(the green ones). anyway, got married, had kids....you know the rest. took them out of the car and they've been stored away. getting back into car audio finally again and would like to get them going. but over the years i've thrown away the spec. sheet for them. i need an amp to run them but not even sure anymore what their RMS is or even how big of an amp to go with can anyone help me????????? would like to go with a JL amp if possible.
Mark, no Infinity component set that has come out, even the newer Perfects, are rated to take 150W+ RMS such as from the JL 300/2. Remember that it never hurts to have too much power IF you're careful, but you probably won't ever utilize it. I believe they were rated at 90W RMS, but I can't remember. If I were you I'd give them about 100W RMS.
Depends on your budget and what you like. Like I said above, having too much power isn't a bad thing if you're smart enough not to mess something up, it can allow a lot more headroom, lower distortion, and better transients. You'll also have less heat at the same power level. When an amp isn't straining to produce power, you'll get better SQ. You'll see a lot of SQ guys running 300+ RMS amps on 100W components, they're just very careful with the amps, and they don't have problems. My recommendation would be to choose your components based on what you like, even if they're rated to take less power than the amp you're going to get, they'll be ok if you are careful not to mess them up, if you hear any distortion, back off the volume. Any component set that can take 100W+ should work well with that amp as long as you're careful. You could also consider a JL 300/4 if you want less power on the components, then use the rear channels for either rear fill or midbasses up front.
well, im going to be buying a whole system... subs ... everything ... and since im going to get a seperate amp for the components, i dont want to waste wattage from the amp, and since JL is underrated, i suggested those PG's because they were 150rmw while 300 peak... right up the JL 300/2's alley :D ... what else would you recommend?
those JL XR650-CSi components look really good. I originally was planning on some mb quart component rce-216's, but these look nice. Question though, Power Handling: 70W Continuous then say, Recommended Amp Power: 25 - 150 Watts ? If it is receiving 150w from 1 of the 2 channels of the JL 300/2 amp, then isnt it going to be getting 150rms? 150 > 70, last time i checked..
CDT's were mentioned above, plus a $400 budget for your comps. I shopped around online and got CDT Euro Sport 630's for $427/pair. You might think about that as an option. They are great speakers, and 150w per channel would do them just fine.
The Eurosports are VERY good components, IMO better than the JLs by a pretty good amount. If he can find the Eurosports for around $400 he'd def. be a happy camper. HDs are very good components as well.
At http://www.mmxpress.com/cdtaudio/eurosport.html the 2003 models of the CDT ES 630's are selling for $494.99, including shipping. There are several web retailers with a matching or "we'll beat any price" policy. I went to thezeb.com, presented my case with the above page, and the price they gave me was $427. To drive them got the PPI PCX 2125 (the old PPI, before Directed bought them out and dumbed them down), 125w x2, very clean, for $349 at the same site. Both the CDT's and the PPI's retail for about $700, so it really pays to surf 'n' shop around.
