speakers

I'm new here so I'll introduce myself first. (Sorry if this is all in the wrong place) My name is Wade and I'm on my 3rd Jeep. I now have an 04 Jeep Wrangler Sahara. I have it lifted to fit 35s (But have 33s so I can still drive it daily), Oversized TBI, Cold Air, and a chipset. I don't plan on...

so i cant stand the sound in my 2004 TJ so im in the works of putting a sub in my rear seat (thanks to TerryMason) but i also want to replace my front speakers with 5.25 inch speakers using an adapter plate on ebay but will it really make a difference?
