Yep, those are 18W3 in a 2001 Celica. This car belongs to a customer of mine and I first installed fout 12's but he wanted it to hit deeper. So 2 18's in a 9.5cu ft ported box and a 1500 watt Memphis class D amp and it slams. I am working on my MK3 which is now a 2 setter that will have 2 12's in a fiberglass box where the seat was and 8" components in the rear. Pics will be awile but will post when done.
