  • Good as is
Style: Singe 12"
I bought thus enclosure because it had the specs I wanted for my 12 alpine s2. It would fit the sub without the trim ring. I had to extensively modify the front to get the trim and grill on. It sounds good but not great this way. Not too much better than the sub it came with, just louder. I'm gonna switch to a sealed box as i miss the clean bass. This box had a delay like it had to load up for fast bass with the alpine. I didn't like it. This is a good sub and box. Just might not want to swap the sub out IMHO. ... show more

  • Toss the K5 Sub - Get a K6 v2
Style: Singe 12"
1. Buy this combo kit (if available used for $71-75, then even better - get that 2. Remove the K5 Subwoofer - put it in storage, sell it locally on Facebook for $40-50 3. Buy a Rockville K6 V2 sub (89.899) and install into this enclosure - Nothing against the K5 but the K6 is an amazing sub for $90 and in this enclosure it sounds amazing. Tight, punchy, musical.
