Get him an ok amp with 60+ watts/channel and a pair of Cerwin Vegas with at least 12" woofers. AT-12, D7, VS-120, any of those (the newer, the lower quality they will be). That should do him well through his teens. It certainly did me
Those car subs are going to sound terrible and be more trouble than they are worth and either the amp or the speakers or both will probably end up damaged in the end. Yep, tried that too as a teenager! And tell your kid; the Cerwin Vegas will thump way harder than anything you can Frankenstein together with the MTX's.
