i have only had this problem in my current car and head unit...i have a 1993 ford ranger supercab, what happens is when i put the volume past a certain point only my subwoofer stops putting out power and seems to shut off,my amp stays on and so does my capacitor, my amp is a pioneer 760 watt ( GM-510T) and my sub is an alpine type-r (SWR-1221D) and my head unit is (CDA-7892), i used to have systems in my other cars and this was never a problem, actually never had this problem till i got this car, all the wires are secured,tight,in the right place,i have power acoustic 4-ga. wire for everything except remote wire and i also have a generic set of rca's, so it might be the rcas but i dont want to buy good ones and realize that, thats not the problem, i need help!!!!!!

and also my other speakers work fine when the sub just shuts off, and when i turn the volume down even just one point it turns back on. also i used to have 12 ga wire and when i put it past that certain level and it shut off i left it there to c if it would turn back on and all it did was blow the fuse from my power wire, even now when i have 4 ga wire and a 150A fuse it still does it, it hasnt blown the fuse yet,i dont think it would though its a huge fuse..

that speaker is a dual 2 ohm voice coil speaker. If you have the speakers coils wired in parallel as most people do you are throwing a 1 ohm load at the amp which will tend to make amps unhappy.

its not that i have them in series, plus this happened to my other sub i had in there. it was a massive 12inch 400wmax and 200wrms with a 300wmax amp. it is really frustrating me bc i just got in my competition sub and amp and i dont want this to happen when i install these in a few days, im trying to think......mmmmm.......what about a short in the wiring or something....cause my amp,capacitor, and head unit all still have power and nothing turns off, just the sub stops working and thats two subs that it has happenned to me...im very upset :( any suggestions would be welcome..thanks anyways ttocs ;)

Adjust the amp gain upward about 1/2 volt and see if that cures the problem. Also, if using the Bass Boost feature, +6dB is plenty.

i have my gain turned to normal, everything is normal...
swez on 07/19/2009 09:16:53
What is normal when your sub amp shuts off? That's not normal and try the fix I suggested and see if it helps.

no it didnt help, still does it...all the connections are normal and my capacitor reads 14.4 when my sub goes off.it is really weird...ive tried messing with all the adjusters for everything, headunit and amp both, still does it
swez on 07/19/2009 09:37:25
Hum, if you bridged the amp MONO and the sub is now a 4 ohm load, that should be good. However, does the amp casing get hot after a few minutes of hard thumping?
The power Cap voltage may be right up there as noted, but what's happening inside the amp is another story. Worst case, you may have a defective amp here and that might need some looking into.

it does get pretty hot, buti had a dif sub and a dif amp a jensen 300 watt amp with a 400 watt sub and it did the same thing except it would turn off when it was less loud as the type-r with the pioneer 760 watt amp,hey and if its defective il just put it in a fire when i install my other amp and sub tm.haha
Dragracer51887 on 07/19/2009 13:07:01
you know what i was thinking swez, it might be my speaker wires going from my sub to the box and then the wires from the box to my amp. they are just regular home speaker wires and their pretty thin and flimsy, i was thinking if i used 10 ga or 12 ga speaker wire it would be able to put more power to the subs, do you think that could be it?i mean i would think bigger is better.......
ttocs on 07/19/2009 14:38:51
so just to confirm, by setting the gain to "normal" you don't have it up any further then 2/3 max right?
So when the sub stops playing there are no warning or protection lights that come on the amp? Can you get a couple of pics of the install? They are worth a couple of words.......
Dragracer51887 on 07/19/2009 14:50:27
yea give me a day and they will be on here
swez on 07/19/2009 16:51:23
Use #12 gage for your sub to amp wiring. That's plenty as #12 is good up to 2400 watts.
Where is the amp installed? Excessive heating can also be caused by poor ventilation of the amp and not being able to cool itself properly.
