Guest jbinn Posted December 25, 2009 Report Share Posted December 25, 2009 Ok so I just installed my Fi 15" SSD into my new vented box I wired it up to 2 ohm and got it all hooked up, the sub was moving but it was barely moving... then I turned the volume up a bit and adjusted the gain, then the sub completely stopped moving WTF why is this happening?? im running an alpine MRP-450 to it right now... omg dont tell me i blew something.

Guest jbinn Posted December 25, 2009 Report Share Posted December 25, 2009 But the amp light comes on.. and the subs I just had in before worked fine I have my ground to a bolt on the trunk, I guess I could refit it, but wouldnt the amp not turn on at all if ground wasnt connected?? also I noticed the blue light on my alpine blinks almost like its surging its not real jurrastic but its noticable.

Guest jbinn Posted December 25, 2009 Report Share Posted December 25, 2009 (edited) Ok they started working I think it might have been a bad ground or a wire that came loose somewhere... I'll go back over my wiring, one question why the hell does the sub flex to little? Even if I turn the gain all the way up and put my deck @ 80% the sub is barely moving... I also have LPF 50hz-200hz and +6dB gain, my deck is also -6 as low as it can go, is it because the subsnot broken in? I'd think @ 450RMS x1 @ 2 ohm the sub would be pounding harder. right now I'm breaking it in, running it @ half gain, +0dB and 50hz LPF... also ahve my deck on 15/30 and all other settings -6 as low as they can go, whats the quickest/best way to beak in a subwoofer, and how can I get more excursion? btw I tried testing the gain output with a 50hz tone and it didnt read irght at all it was jumping from like 18-35 etc. theres no way I could read it, I think my tone disc was messed up som im adjusting my amp by ear since im familiar with clipping and bottoming out.

drewb53 Posted December 25, 2009 Report Share Posted December 25, 2009 i will just say it before everyone else.. DO NOT just turn the gain up to get it to be louder set it correctly.

Guest jbinn Posted December 25, 2009 Report Share Posted December 25, 2009 i will just say it before everyone else.. DO NOT just turn the gain up to get it to be louder set it correctly. how can I set it correctly if a DMM doesnt work? the readout is dumb, I think my DMM is bad or something weird like that... I did AC 800 square root is 28/28 well I wasn't anywhere in that zone it made no sense... Is there a way to set gain without the DMM?

cubs_fan0718 Posted December 25, 2009 Report Share Posted December 25, 2009 (edited) Is ur LPF set on the deck or what? if it is try turning it up to the next 1 (ex. pioneers would be 63) cause if ur breaking it in some people do and some dont, break it in on a higher setting so then the lower notes start coming in and then u can start turning everything up and getting ur freq right. Then that thing will get low low and ull be able to tell when its broke in and adjust accordingly.

kirill007 Posted December 25, 2009 Report Share Posted December 25, 2009 Put you're LPF up to around 70hz. What are you're settings on the amp? At how much hz is the subsonic set?
