I've got a mustang with an extremely crappy stock speaker system. I replaced the factory headunit with my alpine cda-9813, which puts out 27 watts RMS/ 60 peak per channel. Now, I want to replace the two front speakers with a set of decent but cheap coaxs, and I have two choices. Either the Infinity Reference 5752cf speakers, which take from 2-60 watts RMS, 180 peak, and a bass response as low as 54Hz... OR the Pioneer TS-G6840R 6X8 speakers, which take 30 watts RMS, 60 peak, and a bass response as low as 32Hz. Now, I don't ever plan to power these with an amp, since I just don't have the money for all that, so either way, both speakers can take the power my headunit is putting out. The Infinities cost $40+shipping, and the pioneers are $37.95 shipped. Which should I go for? Will they really even be very different from eachother?
