Stereo speaker size

Asked by Oct 23, 2016 at 09:31 AM about the 2004 GMC Sierra 2500HD 4 Dr SLE 4WD Extended Cab SB HD

Question type: General

What size speakers

1 Answer

320

The size is 61/2 but the fact.installed speakers have integrated tabs that secure them . When you remove the speakers the hole isn't designed t9 properly install an aftermarket driver. You can either purchase the adapters or in some cases ex. Alpine ,Pioneer ,JBL include an over sized mounting ring that should aid in installation. I recommend some sound deadening material such as dynamat or fat max to put on door because there isn't much inner door skin and tend to rattle with better speakers. GOOD LUCK
