I just removed a couple of 12" Kicker C12A subwoofers from my 2001 Acura CL Type S vehicle. These hoary subwoofers have had a long and interesting journey. They were originally purchased in 1996 and installed in a stand-alone box enclosure which was placed in the trunk of a Volvo. Then when I upgraded to a 1998 Honda Accord coupe, the same enclosure was installed in the trunk of the Accord. Finally, I purchaed the 2001 Acura CL Type S and the subwoofers were removed from the enclosure and installed in a custom enclosure in the spare tire well. They were powered by a JL Audio 500.1 amp and have served me well for 16 years. The rest of the stereo system (old school German-made MB Quarts powered by ancient school - circa 1996 - Lanzar Optidrive amp) will remain the same.
Today, I removed these subs from the enclosure because they were no longer throwing the same punch that they used to. I hear that subwoofers often lose their punch within 4-5 years after good use. Is there any truth to this?
In any case, there is a point to the story above. I am replacing the C12A with the Kenwood KFC-W3013PS and plan to install the new subs in the same enclosure. Here are my questions:
1) Unless I'm mistaken, car subwoofer technology has progressed significantly since 1996. If the C12A were brand new today, how would they compare with the KFC-W3013PS? Would the Kenwoods throw a bigger punch than the Kickers? The C12A were one of the best subwoofers in their time and I was wondering if the budget subwoofers of today are equivalent to the top-of-line subwoofers from mid-1990s due to the technological progress?
2) Would the Kenwoods fit in the same enclosure as the Kickers? I have not yet compared the dimensions of the Kenwoods but I am assuming that they are bigger even at same cone diameter?
3) Should I upgrade the rest of the system as well? The German-made MB Quart tweeters and mids were purchased in 2000 and I'm not sure if they will wear out over time like a subwoofer.
Any advice and comments are welcome.
