I just installed my new IA 6.5s comps (2 sets) using the rear 2 mid bass only, they are on the IA 6.4 amp, they sound really good but when I try to get the right mid bass coming thru one has a pop to it, and they are just not as loud as I think they should be,so I am looking into the rainbow CS 265.25 just wandering if anyone here as any experience with them , and are they louder than my current set up,I am also using a death row 12 in a sealed box( yes sealed ) and it sounds great it does not miss a beat it is in a 1.34 cu box , any suggestions would be appreciated , 2000 celica
