Ok so I'm at the point now where I have the sub and 6.5s installed along with their amps. Sundown Sd3 12" ported tuned to 32hz running off a JBL GTR1001 @ 4ohms, so its seeing around 700 watts. My 6.5s are NVX SP coaxials running off a Memphis SRX2.150 @4 ohms, amp is rated 50 watts rms x 2 @ 4ohms. Both the amps are getting their signal from my Audio Control LC2i. I have a stock HU, 2018 Chevy Silverado 8" Mylink Non Bose system.
So to start, on the HU I have my EQ set in the negative for bass, prob about +4 for mids & +3 for treble. The LC2i is tapped into my front L & R speakers behind HU for signal (Stock speakers no longer installed, just unhooked them & bypassed factory wires) I read that the front speakers are better to tap in the Silverado b/c they recieve a full range signal.
The LC2i is setup as follows, Accubass threshold is set all the way to the right bc when I did the test for bass roloff I didnt notice the bass going out or lower @ any point, I really listened & tested quite a few times but never noticed anything. Then the Accubass knob is @ 12 o'clock, Main (speaker amp, Memphis) @ 12 o'clock & Bass (JBL amp) about 2 oclock.
The JBL GTR1001 is set almost all the way down, bass boost almost all the way down, 0 degrees phase setting, My LPF @ about 80hz.
Finally, Memphis SRX2.150, gain is all the way down, have it set on the High Pass Filter, which is set quite high, if I set it under the halfway point (Only indicators I have are all the way left is down to about 30hz and all the way right is above 1khz, so I feel like halfway would be pretty high where I shouldnt have any bass coming out of them, but if I set it any lower and turn the volume up about halfway I hear a decent amount of distorted bass trying to come thru the speakers. Now I maybe wrong but I feel like I should be able to set the HPF @ like 150hz and not have a problem with too much bass trying to be played thru them?? I then have the boost set @ 0. I feel like I can tune this better, they sound really good, but I feel like they could be better.
I also noticed when I attempt to turn the gain on the amp up over like 1/4 it almost acts like a fader, the sound from the speaker goes to the passenger side and goes silent (or very quiet) on the driver side. Don't know why itd do that.
Any tips? Ideas? I have a multimeter that I can use, I actually tried to use it to set the LC2i, but when I did that I got my voltage output I needed was like 42 volts I believe and when I put the meter on the speaker outputs of amp with the lc2i bass knob all the way down I was at that 40 volts already and the more I'd turn the knob up, the voltage # would actually drop. I followed the instructions, had the 50hz test tone playing, sub was unhooked, just didnt seem to work.
So any pointers would be greatly appreciated! Thanks!
