Let me answer a question most would like to know right out of the gate....How much does it cost & what do you need to do this with all oem HD stuff? Well be prepared to spend between $1500 to $2000 depending on whether you install yourself or use a dealer. You do need to flash your system for the new amp @ the dealer. (Most charge 1hr min) Note: MUST LEAVE AMP UNPLUGED UNTIL THE SYSTEM IS FLASHED
Parts needed:
Speakers
Speaker install kit
Amp
Amp install kit / wiring
Install kit template addition / update, believe this is included in newer kits.
Small power spliter harness (part guy thought I might need) didn't use.
Why? Well 6 speakers has to sound better than 4 right? And I wanted more / clearer sound at a lower volume & not cut up the bike with aftermarket, plus keep all HD functions working properly (Plug & Play). I also purchased parts over time and used discounts / points to keep prices down. Also did install myself. Managed to keep final cost around $1200.
You have to remove the seat, side covers, bags, gas tank & front fairing cover to complete this install.
