toylocost Posted August 10, 2010 Report Share Posted August 10, 2010 Amp is a Pioneer Premier GM-7150M and the sub is a Pioneer Champion Series TS-W308D4. The sub is dual 4 ohm and we are running the amp at 2ohms. Its okay for that amp to do 2ohm. I was not in the car when the problem started it but here is what I got from it. Stereo was up about as far as he wanted to push it he smelled "something similar to burning fiberglass" then the sub slowly faded away. He says he thought the smell was something like the sub breaking in. Power light on the amp was gone. Ended up replacing both fuses in the amp, main 4ga fuse did not break. Amp turns back on now but will cut out for a few seconds 2-4, then turn back on for another few seconds 3-5 maybe. Temperature or volume doesnt seem to matter it does it all the time. I'm thinking the amp is fried. Any thoughts? BTW amp was bought used sub was bought new in april/may. Been running since late may. Quote 99 4runner - So far: Alpine PDX4.100 & AQ1200D.

Guest Posted August 10, 2010 Report Share Posted August 10, 2010 sounds like amp is fried or the woofer is fried...check ohm load on woofer on both coils and open up the amp and see if there are any burnt/black looking pieces in it. Quote Link to comment Share on other sites More sharing options...
Loudcivic Posted August 10, 2010 Report Share Posted August 10, 2010 unhook the sub and see if the amp acts the same. could be a fried coil on the sub. if it still does it with the sub unhooked then it could be the amp. check all wires make sure grounds are good but its proly the sub or amp Quote 2015 silverado crew cab nothing atm but soon...

toylocost Posted August 10, 2010 Author Report Share Posted August 10, 2010 To check ohm load on the VCs I just use the meter and go + and - and see what the resistance is?

Loudcivic Posted August 10, 2010 Report Share Posted August 10, 2010 yes Quote 2015 silverado crew cab nothing atm but soon... Link to comment Share on other sites More sharing options...
Freshman6969 Posted August 10, 2010 Report Share Posted August 10, 2010 To check ohm load on the VCs I just use the meter and go + and - and see what the resistance is? yes with a DMM or something that reads ohms, check your grounds tho, cuz the whole ride to carlisle my amp kept cutting out on me, turned out to be when my friend sat a certain way on the seat the metal from the seat hit where it was grounded so it shut my amp off Quote Legal TL scores145.6 on the dash sealed up in the low 40hz area with the port out145.5 on the dash sealed up @30hz with the port inless then 1k clamped on a 3.5k! Why would you EVER WANT flex?huh?...flex is what can make the lows lower and more air being pushed correct?

toylocost Posted August 10, 2010 Author Report Share Posted August 10, 2010 Actually thats a good point it cant be the ground because the power light never cuts out its always on.

toylocost Posted August 11, 2010 Author Report Share Posted August 11, 2010 OK so we got the sub pulled and heres what we found. 1st VC (supposed to be 4ohm) 2nd VC So something is fucked up. Assuming I get another sub, whats to say this wont happen again. I don't know what the original problem was but this is the aftermath. He also said he thinks he bottomed it out pushing it too hard once. Idk if that would have anything to do with this though. Quote 99 4runner - So far: Alpine PDX4.100 & AQ1200D. Needz speekrz yo.

Rebel4055 Posted August 11, 2010 Report Share Posted August 11, 2010 OK so we got the sub pulled and heres what we found. *snip* So something is fucked up.

He also said he thinks he bottomed it out pushing it too hard once. Idk if that would have anything to do with this though. Yeah that sub looks gone. My buddy blew his 2 subs and one of them read 0 on one VC and like 1.x when it was dual 2 ohm. Quote Rest In Peace mother.
