Incorrect. Underpowering will never blow a speaker.Infinity kappas, rockford subs, 0 gauge wiring, dry cell, deck, amp. Athough I would recommend getting a 2 channel deck instead of a 4 channel unless you plan on upgrading to 4 speakers. The number one cause for speakers to blow is being under powered.
what about headunit? front speakers? 2 channel amp? custom box for the sub? not some prefab from best buy..he might as well do it correctly the first time around.I bought two 10" fosgate punch's and an fosgate amp in a hatch back box for around $300 a few years ago. Got it brand spankin new from best buy.
yeah, my hatch already came with a head unit and mids so I was good on those. The only way he'll get a complete system for under $500 bucks if is he goes to a flea market or buys it hot.what about headunit? front speakers? 2 channel amp? custom box for the sub? not some prefab from best buy..he might as well do it correctly the first time around.
the only thing i wouldnt skimp on is the head unit. your system is only as good as the hu.
