[QUOTE="BenH, post: 8865200, member: 690429"] I appreciate the help, but you seem to be continually making this more confusing in areas where it doesn't need to be. For starters, all I have ever asked is about replacing the rear speakers. While I might have mentioned that my front door mid-ranges might need to be replaced as well, they were not part of anything I have been asking since day 1. Bringing all these other parts into play when we are just trying to answer the main question I posed just causes us to go off track and loose the main point. For starters, you seem to be conflating multiple sources I have sent you. The "blog" guy and the PB guy are not the same person, and I wouldn't expect the PB youtube guy to remember. He states as much in his comments from others that he didn't recall, nor would he since he was basically ripping out the whole system anyway. I'm 99% certain both from things I recall reading on the Toyota forums and because the blog post (again not the PB video guy, but the blog post I linked 3 or 4 times) specifically uses the Alpine SPE coaxial speakers, that the crossovers are electronic and coming from the amp itself. My goals are basically these, and I'm not really willing to compromise on any of them: 1) Not lose any functionality from what I have. Meaning I am not willing to lose both channels in the rear and only get one frequency. 2) Not lose any appreciable volume to the system. I would say a 10-15% drop in max volume may be acceptable, but anything beyond that I would not want. 3) Not looking to modify my vehicle. I don't want to drill holes in my rear deck. I don't want to carve out plastic on my top to fit tweeters in. The link you sent for those didn't work, but again, I don't see how it is possible to put another tweeter anywhere else under the rear deck cover without cutting out an area for the grill to come through. I'm not willing to modify the vehicle in this way. 4) Cost. Which basically means I want to replace any component that cannot be repaired only if required. At this point, I know the rear mids are bad, they need to be replaced. The front door mids may be the next job after that, but I'll address those once these are done. I think the only concern that might exists regarding doing the fronts later is that if I happen to put a 4 ohm in the back, and then *also* in the front that might mean a larger volume drop (I think?). My question still regarding the Alpine SPE-6090 that the [B]blog[/B] post uses is that they are rated at 4 ohm. Because this is a coaxial speaker with 2 components, does that mean each speaker is rated 4 ohm, or because I need to split them up will they each be less resistance? I really don't fully trust any of these folks because they all recommend 4 ohm speakers, but don't really warn that you are going to have volume issues with them. Any comments which attempt to address that issue appear to go unanswered. So I am NOT concerned that 4 ohm speakers won't work, because I am confident the crossover is done in the amp based upon other things I read. But I am concerned that 4 ohms speakers will cut down on my volume. I don't blast my stereo, but as I can't really know what the drop will be, I am concerned to risk it. It looks to me like my options are either: If I want to go component, and try to reuse my existing tweeter mount: [MEDIA=amazon]B0B3F7V1YC[/MEDIA] If I want to go coaxial and snip the tweeter wires: [MEDIA=amazon]B099FJHCLC[/MEDIA] Won't both of these work? If not, why? And barring these do you have another specific suggestion. thanks [/QUOTE]
