I picked up a 09 Enclave CXL for 4,400$ 155,000 miles. About 7 yrs ago I helped my buddy move. During he gave me a 10" JL sub in a JL box. I dont know anything about it except I've always planned on using it. Well that time has finally come. My question is what kind of amp to run the sub and all new aftermarket speakers. I'll probably only spend about 200$ to upgrade the current speakers and I'd like to stay around that price ranfe on a amp. Is this possible and will it sound decent??
