i have infinity references all around, with rockford punch P400-4, and a kenwood KDC-MP438U headunit. do you u think thats a a good set-up or i could have done better? just tell me if its a good set-up.
Sure you could always upgrade. But I think your system now is a good setup. Aftermarket speakers with an amp, and a aftermarket head-unit are always better IMO than factory. Now if you added a sub or two in a proper enclosure with a amp matching the sub RMS that would really be even better.
