n8ball2013 Posted February 17, 2011 Report Share Posted February 17, 2011 Heres another thing. If you had updated your entire profile and put in your location you might actually have someone close by that can help you. You seem to be in a little over your head and could probably use a hand from someone who knows whats going on. That tiny little bit of info might be able to save you a lot of headaches in the long run.

bobonit Posted February 17, 2011 Report Share Posted February 17, 2011 Set the DMM to AC Voltage, then check the outputs on your Headunit. If you don't have any voltage on your headunit, that is your problem. If you have voltage on your headunit, connect the RCA's to your headunit but not your amp. Check AC Voltage on the unconnected end of the RCA's. If you don't have voltage, you have bad RCA's. If you have voltage on your rca's, connect the RCA'a to your amp and check ac voltage on the outputs of the amp. If you don't have voltage, you have a broke amp. If you have voltage on your amps outputs, check your speakers. Hey I put it on ac and check my RCA on my hu and read 0 I put both of them in the hole for the RCA and rub them on the RCA on hu and still 0 so Its the hu. Before I had a Bose hu and got the Loc called the mx-4 for my RCA and it still hook up but no power going to it tho. Dude, you put one probe in the hole and the other probe on the outside of the same connector. IF you have them both in the hole you won't read anything.

notorious97200 Posted February 17, 2011 Report Share Posted February 17, 2011 Your LPF is set at 30 Hz ? Move it up to 80 Hz. Or is it your subSonic Filter : at 30 Hz it can be good if your box is tuned at 33.

The easiest way to trouble shoot it is to swap head units.

CJ18 Posted February 18, 2011 Report Share Posted February 18, 2011 (edited) Make sure that your RCAs are plugged into the sub output rcas and not aux rca on your HU. I had a friend install a sony HU that had front rear and aux rca plugs on the back of the hu and then the sub rca wasnt labeled but was separate.

I had a friend install a sony HU that had front rear and aux rca plugs on the back of the hu and then the sub rca wasnt labeled but was separate. I got my RCA plug in the bottom RCA on hu. That's were it said in the the book to hook them up in.. This is the only setup I hook up with this problem. I still have my Bose speakers hook up with bose amp and this my first time going after market hu. And dont work.. But the Bose speakers and Bose amp have nothing to do with it does it?????
