Hi jimbones, You will love the 3.7i ! Although I would prefer more power your Wells will do fine up to around 90 dB. Sonically it will be fine. If you ever decide to get subwoofers your headroom will increase to 95 dB. I have set up two 3.7 and four 20 series speakers with subwoofers so if you ever get to that point I would be happy to help.
