Al LaPorta Posted August 31, 2015 Author Report Share Posted August 31, 2015 so another update, I pulled sub all connections are tight, final impedance at the amp is 1-1.1, I went to a NESPL event in Mass yesterday and met EXO.. was talking to him for awhile about my issues and he agrees it is a combination of amp not getting enough signal from LOC and the box isn't built right.. really down to earth guy he gave me a demo in his ford, 6 18s on 24k.. took my breath away anyone care to school me on the DDM? how to use it and or how it works? thanks ahead of time Link to comment Share on other sites More sharing options...
tboorn Posted August 31, 2015 Report Share Posted August 31, 2015 do you mean DMM (Digital Multi-Meter) or DD1 (distortion detector by SMD)?

reedal Posted September 1, 2015 Report Share Posted September 1, 2015 The directions that come with the DD-1 are really basic and easy to understand. You should have no issues as long as you follow them. Please do not use the -15dB track, for your subwoofers safety. -10dB is pushing it for most music. The fact that you're using an LOC would have been helpful in troubleshooting your problem.

I ripped everything out last night and started from scratch. took my time and re wired everything its kind of a pain in the balls since my A4 has the non bose system... still has factory rear amp so wiring was a little confusing at first, re wired everything up and I still cannot get the amp to draw enough power im really getting to the point that i just feel like ghost riding my car into the ghetto with the keys in it hahahaha Link to comment Share on other sites More sharing options...
reedal Posted September 1, 2015 Report Share Posted September 1, 2015 So why do you want to retain factory radio? What LOC are you trying to use?

Al LaPorta Posted September 1, 2015 Author Report Share Posted September 1, 2015 So why do you want to retain factory radio? What LOC are you trying to use? because I don't feel like ripping my car apart again haha but no seriously I figured it would be fine I read somwhere that my OEM HU has 10v pre out voltage my last build was my gti on a LOC with 2 XXX 15s on 2400rms and it was 5x as loud I dont get it Link to comment Share on other sites More sharing options...
Al LaPorta Posted September 1, 2015 Author Report Share Posted September 1, 2015 car voltage does not drop below 13v if you didn't know what i had you would think im running a 500 watt amp on 2 12s Link to comment Share on other sites More sharing options...
reedal Posted September 1, 2015 Report Share Posted September 1, 2015 What LOC are you using? Or are you saying the OEM radio has RCA preouts?
