Different equipment is because: I had a system that you see on my sound domain and wanted to upgrade. The wife would not let me upgrade everything as I was spending to much money. I did not like the tweeters that came with the Diamonds as they really did not take the power . I got the r25 as they sound very good to me and they really can take some rms and worked real good with the ohms that I needed. I got the kicker rmb8 as At the time (1 year ago) nobody had to much to look at for midbass. I had talk to dan from adire at the time and he had nothing ready to go. On day I will get all the componutes to match up front but I am going to need a bit more money for that. the mtx amps are some good a/b amps that I have around. The wife is not ready for me to change them. I will be changing them so as to match. This will take awhile. The not changing then is due to very high doctors bill as I did not have insurance and have to pay over $3,000 a month to keep up. so when I get caught up, I might change them then I have been working on this install for about a year now, with down time due to the eye. The total will be 4800 rms to the subs 700 rms to the midbass 1000 to midrange 700 to tweeters There is a bunch of switches to turn half the system off for daily driving, turn on for high dbs. I should be able to run the whole system at full tilt with every speaker running and not hurt the speakers and still get crazy loud.
