[QUOTE="ThxOne, post: 8700131, member: 675210"] I went out to the car, disconnected all the speaker wires from the amp and labeled them. I took out my DMM and turned my gains down all the way. I used a 1khz -5db tone and set the gains on the amp for the mids to eventually 18v (18.2v actual) - should be 80w approximately at that setting on a -5db signwave. I then set the gains for the tweeters... again this DMM wanted to say 9. blah blah volts... wtf???? So I found my CHEAP red harbor freight DMM and tried that. YAHTZEE!! Ok, now I was able to set the voltages for the signwaves. Mids to 18.2v and the Tweets to 15.5v (15.6 actual) on a -5db 4khz tone - should be 60w approximately on that signwave. I also had to reset the EQ in the DSP for the sub as it had been boosted above 0db in a few frequencies. So now nothing in the DSP is above 0db. The tweets levels -7db and mids are 0db in the DSP. Volume on the head unit is 36 of 40 (per suggestion of the DSP). All EQ's flat in the DSP (EQ set in the HU.) The sub is crossed over at 90hz 24db. The mids are crossed over at 90hz - 4Khz 24db. The tweets are crossed at 4Khz 24db. Distances for time alignment reset for the tweets, untouched for all other speakers. Now! The system sounds so ridiculously clear when listening to specific songs that show off the clarity of a system. All of this at MAX volume. Kick drum is snappy as f**k, bass guitar is clear, vocals don't sound hollow, cymbals are crisp and not over powering. The problem... it is not loud. Ok, It's loud but not to the point it will overcome road and wind noise at 45-70mph. I can hear it at those speeds with the windows down but it is softer and less detailed then when driving under 45mph or with the windows up. Pretty sure this is normal but my ears need the extra DB's for sure when the windows are down and winds are making noise. One more issue. Now that the distances are again set for each individual speaker... the left side of the cars speakers sound close where as the right side sounds properly far right. Center image is slightly to the right of the steering wheel. How do I push the left speakers out to the left more... like, a lot more??? I have distances and levels to play with for each speaker.
