Well i have a delimma. I recently installed a new amp and speakers in my glide and tuned them properly using a DMM and i am not as impressed as i thought i would be. here is my equipment:
Stock HK head unit
PAC SNI-35 low level line converter
SounStream Pn4.1000d amp (250w x 4 at 2ohm, 140w x 4 at 4 ohm)
Biketronics 7.1 titan II in fairing (factory location)
Biketronics 6.5 Titan II in lower fairing speaker pods
Speakers are wired in parallel to achieve a 2ohm load per front channel
Formula used to determine proper voltage - V = √PxR
V = Voltage at amp output
√ = Square root
P = RMS output of amp at required ohms
R = ohms the amplifier will see from speaker(s) on that specific channel
I got the formula information from this thread over at HDForums.com. It was later determined in that thread to use the RMS watt rating of a single channel instead of both front channels combined.
Setting Amp Gains by Ear and/or with DMM - Harley Davidson Forums
So based upon my setup i used the following numbers in the formula.......
V =√(250 x 2)
V = 22.36
So based upon this info i proceeded to adjust my gains using the method described in the above linked thread. I turned all my settings on the HU to flat and turned off the AVC. Then i inserted my 1000HZ 0db test tone cd that i created. Once that was playing and on repeat i checked the voltage coming out of my low level lin converter and noticed that it is only 3.3 volts with the adjuster turned all the way clockwise and not a true 4 volts. Could this be the reason? Next i connected my amp inputs and adjusted my gains to the proper Voltage. the closes i could get it to 22.36 was 22.2. This left my gains at just shy of the 10:00 position. Trying to adjust it with the bike running made for very unsteady hands....lol
After i made the adjustments i proceeded to play a cd of mp3 that i had and noticed that certain songs were clipping. i did some research and saw some threads on here that recommended i use mp3gain to level out the volume across my songs. So i did that. at first it showed that all of my songs were clipping and set at well over the recommended 89 dbs. I adjusted them to 91db which was the sweet spot where i only had 3 out of 121 songs that were clipping. I burned them to a new cd and proceeded to test out the new adjustments and that is why I am here. They are clear with none to minimal distortion but i feel that the are not much louder then if i had the stock speaker turned all the way up.
I am in need of you guy's expertise!! Please help point me in the right direction. Thanks.
