Hey im wondering if any one knows of another 8 inch sub that will fit in the stock location of a 05 ZX5 that will hit harder? i have been thinking about putting a 10 inch Solibarix (excuse my spelling lol) but im afraid i would have to put a seprate box in my car. i meen if i cut a square whole in my old factory box i dont think it would sound right. any ways any info would be appreciated.
