- '99 XLS
I just installed a set of coaxials (Infinity Kappa 572.5cf) in the rear doors of my 99 XLS. I have an Alpine HU that I think supplies roughly 18-20 Wrms per channel. No amps. The sound improvement is not as good as I expected it (particularly the bass). Now I don't expect alot of bass out of this set of speakers, but they don't even sound that much better than the Ford stocks that I pulled out.
Can someone confirm this is because I'm not supplying very much power to the speakers from the HU? The 572.5cfs are rated for 100Wrms and I'm feeding them much less. Also, I installed the crossover that came with the speakers. Is it filtering out some of the lower frequencies? Can I cut out the crossovers until I get an amp?
Also, I'm hearing a slight hissing sound when I play the radio (FM), but it goes away when I play a CD/MP3. Can I chalk this up to bad reception? (Stupid question, I know, but the directions for the speaker wiring diagram weren't very good and I basically had to guess which outputs from the crossover went to the woofers and which went to the tweeters).
I still have the trim panels off the back doors so hopefully one of you guys can respond. On deck for the afternoon is the components for the front doors...
Thanks in advance for any feedback!
