JR Yonts Posted September 15, 2015 Report Posted September 15, 2015 So I have setup everything with my DD-1 but now my subs have maybe half as much bass as before, so my question is is that all my amps are capable of putting out with clean power? Quote

JR Yonts Posted September 15, 2015 Author Report Posted September 15, 2015 I used Snows 40Hz -7.5dB track. Quote
reedal Posted September 15, 2015 Report Posted September 15, 2015 Could be. What amps? What is your music source connection (USB, Bluetooth, aux, CD, etc.)? Do you use downloaded MP3's? A lot of things effect the output level of your music.

rockFord_Expedition Posted September 15, 2015 Report Posted September 15, 2015 How did you find your HU max volume, and which one do you have? Quote Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire
JR Yonts Posted September 15, 2015 Author Report Posted September 15, 2015 Im using the same usb mp3 music as before the only thing that has changed is I used the DD-1 to set my gains.....Im running 2 Pioneer GM-D9601's to 4 SA-10's Quote
JR Yonts Posted September 15, 2015 Author Report Posted September 15, 2015 I used the DD-1 to find my max volume of 30 with all flat eq, its an Alpine UTE52BT Quote
reedal Posted September 15, 2015 Report Posted September 15, 2015 I believe on alpine units, you have to have the subwoofer level all the way up. Try that, reset gains, see if it changes any. But music is recorded at different levels. And depending on where you download your MP3's from, they could be compressed and altered, meaning that while the original music may have started at -5dB, it could be at -10db or lower, making it quieter than if your amplifiers were set at -10db Also, with using two separate amps, you may need to match the gains. Find your maximum clean level, use a DMM to measure the ACvoltage output of both amplifiers, whichever one has the lower voltage, adjust the higher output voltage down to match the amplifier with lower voltage.

rockFord_Expedition Posted September 15, 2015 Report Posted September 15, 2015 That HU only has 2v preouts. When you find your max clean HU volume, start with the subwoofer level all the way up on the Alpine and only back it down as necessary. What are you wired to? If your electrical isn't strong enough to support the demand your power can get dirty real quick. Quote Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire
JR Yonts Posted September 15, 2015 Author Report Posted September 15, 2015 Im running at 1ohm on both amps and I have the big 3 upgrade. what Im saying is my system sounded extraordinary until I set the gains with the DD-1, but now it just sounds ok and nothing else has been changed. Quote
