I am days away from getting my M3Ti's and wanted to know if i should get a center channel second or a subwoofer second? I will be getting each piece about 2-4 weeks apart so thats how long i will have to go without getting the next piece. I assume i should get a subwoofer second but have read about people just having the three front speakers for a while the upgrading the rest.

Thank you

Kore
