[QUOTE="fossil99ca, post: 446916, member: 554480"] I disagree: I would speculate that every good review you’ve heard on the CDT’s are when they are properly amped. Point-out some posts/reviews were some guy says, “I’m under powering my speakers by a 1/4 and everyone just can believe how amazing they are. Why do they even sell amps in the first place when you can run everything off your HU?” You can’t change the laws of physics. Running 90 RMS speakers, which could probably handle more than that, off a 22 Watt RMS head unit will not produce the same results. You’ll just end up turning the HU volume up way too high to get any volume out of them, producing less than desired results and maybe damaging them or the HU. Again, I would speculate that they would not sound much better than the infinity component speakers. The highs will sound a lot better at first (then stock) thinking you made the right decision but the mid-base wont have the power or precision they’re capable of. You’re only as good as the weakest link. Do yourself a favor and at least plan for an amp upgrade and watch your HU volume in the meantime. When doing the HU/speaker install it might be cheaper to run RCA’s and speaker wire now, than tearing apart your dash/doors twice. Personally, I would save on the rear drivers and get a 4 channel amp (something like 4 x 90 watts RMS @ 4 ohms). It will be more expensive (or look for used) but this way you power your front speakers at rated power. This will negate the need for rear speakers so much. You can run your rear stock speakers off the HU @ 22 watts for fill at the same time if you want. In time you can expand, you will be either able to drive good rear speakers at 90 watts x 2 or you can bridge the 2 rear channels for a sub at about 360 watts. Make sure you have a LPF on the deck or amp. I’d go for the sub to fill the lower end, sounds better, wont wreck your front sound stage and it shakes your mirrors and impresses your friends. Sorry for the long post. [/QUOTE]
