Brother there are endless woofers and amplifiers available . A big enclosure can produce the groundshaking bass you are looking for . A branded sub (new or used ) according to your budget and an amplifier of enough capacity to power your subwoofer will be required . If you go for quality setup . Then it would be in 13-15k . But the cost can be reduced if you buy almani/weconic etc amp and subwoofer. But wont be as durable . This setup can be done in almost 10k +-
