Subs not working??

[Joe Vance]

I dont know why they arent working, my last amp i used went into power protection mode. So i got a new one, bigger and better. The Inline fuse is not blown, the fuse on the amp is not blown. The Amp turns on and works, the needles on the amp spike so its clearing pushing something, but the subs are not hitting at all....I can feel power going into the subs when i touch both pos. and neg. on the sub inputs. help please.


Here is a diagram of the set up. The first diagram was the wrong one sorry, putting up the right one now.

your using your stock radio, check the settings on the converter and the radio and the amp. and you may want to try hooking up another sub to see if yours are blown out.

How many subs? what amp? what subs? do you have access to another sub you can try?

do you have a multimeter to take some readings?

 

[Joe Vance]

The subs dont look blown they are in a box with plexiglass over the front, and its a boss amp and auidobahn subs. The line converter is on the right settings.

I dont have another amp and or subs to test this, but i have a test light, but that wont help me find a short - but i doubt its a short because i just put a new wire setup in the works. And it was working perfectly fine so i dunno...do i have something wired wrong?

 

[Joe Vance]

Does it help telling you that the subs are on a bridge on the amp?

 

[MAZDA_SPEED]

its your amp...get a real one..(nuts)

 

[Joe Vance]

How is it my amp, the fuse isnt blown, its clearly getting power, its not in power prot. and its still pushing something out....and the amp is actually a decent amp, its a boss rage... 1200 watts bridged

 

[Vord]

Boss is a pretty crappy company. I doubt your amp is able to put 1200 watts bridged (if that is the claimed power from boss).


None the less, if you plan on working on electronics then drive down to Sears and buy yourself a decent multimeter for 30 dollars. Otherwise man, I can't help ya.

 

[Joe Vance]

Bumping this back up because I need to know if someone thinks it might be a short in my sub wires, the ones coming from the amp to the subs?

 

[MAZDA_SPEED]

why would you touch the pos+ and neg- together? doesnt seem smart to me... did you get a multimeter??

 

[Joe Vance]

the multimete me and my buddy use for most of our stuff seems to be flawed or there wasnt a short in the wire on the last project. But what are you talking about touching pos and negs?

 

[ecniemann]

Try ANY speaker you have laying around to rule in/out the amp. Play it at a VERY low level. If you get output throught he speaker, it is your sub; if not it is your amp or wiring.

 

[P-Funk!]

True. Without a meter you can't tell if the wires inside the box are shorted (shorted wire or fused speaker coil).

I have a old boom box with speaker connections and RCA inputs and outputs. I use that for t/shooting.

OK, so you have two subs bridged... are they in parallel or series? Are they single or dual voice coil? Are the voice coils wired in parallel or series? If the subs are in series, if one sub quits, they both quit. If they're in parallel one would keep working. If dual voice coil, same thing, series, whole speaker quits, parallel speaker will keep running on one VC. Subs never look blown from looking at them. I would take them out of the box and measure the resistance on them. Should probly be somewhere from 2 to 8 ohms depending on what subs they are. If you get a high ohm reading or no ohms (no resistance) then there's a problem. But you really need to get a multimeter, you can get some pretty cheap ones that will do the job.

^ I second that, and please get a better amp or just run that one at 4omhs if you can. That amp insn't efficient for crap.
