Sub stops working at higher volume

LAKE_RAT · 11-07-2009, 12:40 AM

Alright here is my problem i was listening to music last night. hittin good like its supposed to. go up this morning went out started it up, headed to school, turned it up not really loud just listenin to country with very little bass and it worked up till i got to 27(out of 60) on my volume. got home and tried everything i could. looked over wires,even changed fuses. still cuttin out at 27 no matter the music type, works good before 27 tho . really baffled. anyone have any ideas or fixes to my problem?

What subs, ohm load, how are they wired, amp? Ground on the amp good? (my money is on ground)

LAKE_RAT · 11-07-2009, 12:46 AM

ground is good. its a pioneer 12". 400.1 Phoenix Gold Amp. 8awg power and ground. 4 ohm load

**08RCSB** · 11-07-2009, 12:47 AM

What's a "good" ground?

LAKE_RAT · 11-07-2009, 12:50 AM

Bolted down. not loose. i used the bolt that held my rear seat to the cab

ADAMWEDGE · 11-07-2009, 04:20 AM

your remote wire connection good? crimp your ground in an eyelet,use washers then bolt it down.

OKLAGMCRUISER · 11-07-2009, 10:11 AM

amp may be going into protection due to too low of a resistance. is the amp stable at ratings below 4 ohms? are you sure the sub's voicecoil(s) are wired in a 4 ohm load?

LAKE_RAT · 11-07-2009, 07:42 PM

the amp is stable at ohms as low as 2.
i thought it may have been the remote wire but i checked and its good

saggin92 · 11-07-2009, 08:00 PM

im thinking protection mode also

LAKE_RAT · 11-07-2009, 08:13 PM

if it is, how do i get it to stop going into protection mode?

**08RCSB** · 11-07-2009, 08:17 PM

Start with the ground. Seat bolts usually aren't preferred.

on1wheel06 · 11-07-2009, 08:38 PM

did you sand to bare metal for the ground?

LAKE_RAT · 11-08-2009, 01:29 AM

its bolted to the bare metal of the cab. got an idea for tomorrow tho. ive two holes in the back where the spare tire used to be, ill take the bolt out of the hole and run it straight to the frame. that should tell me if its the ground or not im pretty sure

LAKE_RAT · 11-12-2009, 12:56 AM

not the ground. bolted to the frame. didnt work. im stuck now

jrmchevyman · 11-12-2009, 01:41 AM

if you tried all of the above it might be the amp itself.. What is your voltage btw when you turn it up to the point to where it fucks up? I would do the easiest troubleshooting step possible and try it with a different amp. Maybe borrow a friends amp but set gains accordingly if it is a more powerful amp.

**Forklift** · 11-12-2009, 10:25 AM

Id disconnect the sub and try it again just for shits and giggles

LAKE_RAT · 11-15-2009, 03:16 AM

i havent checked voltage *yet* ill do this in the morning. im probably going to borrow an amp and see if its the amp itself.
