Front and rear speaker upgrade

[williamson_l]

I have completed my speaker upgrade. I installed the Polk Audio db501's (5") in the rear and the db651's (6.5") in the front. In the rear I only had to slightly rotate the speakers to get enough plastic to allow me to drill new holes as the stock did not match up. As for the front, I opted to time the speaker frames on the sides to gain the clearance required. Also, on my bike the stock tweeters come off the same line as the main speaker from the amp so they were not reconnected. In previous posts I have seen that people say the speakers had to be installed upside down. Not sure why that was as mine fit perfectly right side up.

I did a 300 mile ride today and with my helmet on (of course) not one time did I have to switch to the headset. It was plenty loud at highway speeds.

When I first installed Polk speakers they sounded awful, worse than the originals. until I discovered my radio unit had a naff amp chip. Being in the UK I could not get it upgraded, So I decided to re wire the speakers, install a Rockford Fosgate amp, competition cap, and 8" subwoofer.... OMG. Oh and a second car battery

Luckily I didn't have to got to all that trouble mate! However, I did not reconnect the OEM tweeters back up. Reason being the amp only has one output per channel. R/L for front and rear. No separate bass/tweeter output. Either way I could not be happier with how they sound. I wonder if that may also be the case with the Canadian bikes too.
