eliassami5 Posted March 28, 2009 Report Share Posted March 28, 2009 (edited) So the first speaker i had in the door was an Alpine type S and it blew cuz it had a hole in the surround and the cone was cracked. Second, fourth, and third speakers were some cheap Insignias that i bought when i first got my jeep, they are rated at 50 watts rms, and they all blew within a weak of instillation. And the fifth speaker i just swapped in today from the rear hatch of my jeep to the front door was also an Alpine Type S, worked fine in the rear...instantly blew in the front door. Im running an alpine MRP-F300 which does 50w rms x 4, so i cant see why the Insignias blew from that...maybe they really are just that shitty. All other speaker are running fine and none have blown since i initially installed them, which was about a year and a half ago, except the front passenger door which keeps eating everything i throw at it. Now i had always thought i was just blowing them cuz i played my music too loud but after i blew the Type S today right after moving it from the rear to the front im starting to think something is wrong my amp. Im still not sure if its the amp or just that it was the speakers time to go...but im gonna be getting some Phoenix Gold comps in the future so i wanna get this thing solved before i put them in so any ideas of why they would do that would be cool.

mrwigglezdj Posted March 28, 2009 Report Share Posted March 28, 2009 well i dont know if it would be even close to my problem but im always blowing speakers on my doors, ( but i have 6 in each) i just learned that i have 4 on each door with bad tweet/woofer and have to be replaced, im only puting 50rms to each speaker which is mfg amount, but i belive it has alot to do with how i play, ill demo for anyone at the audio shop, and give it all she has untill im done or the person geting the demo is done and ran out the van, but it boils down to proper seting of the amp, youre sending dirty power to the speaker burning it up like im doing with mine, so get a speaker that can take the power and then have the amp properly set so you wont burn any more up Quote Americas loudest work van2006 iasca heavyweight bassboxing champion at 150.4 db with 60second average TL8 memphis PR15s,12 memphis PR6.5's coax,4 memphis PR 1inch tweets Link to comment Share on other sites More sharing options...
eliassami5 Posted March 28, 2009 Author Report Share Posted March 28, 2009 the amp is as properly set as it can be with a DMM, if i had a oscilloscope or knew how to use one then it would be even more accurate but yea that was the first thing i took care of when i installed the amp. the high pass filter is at 100hz and all the channels are set to high pass.

Guest Posted March 28, 2009 Report Share Posted March 28, 2009 the high pass filter is at 100hz and all the channels are set to high pass. you dont really need a high pass filter on your speakers since they have a built in one Quote Link to comment Share on other sites More sharing options...

Then 10min later i took a drive around the block to see how it sounds and it started to make weird noises, turned it down and figured it was nothing, turned it back up and the noise got louder and louder until i took it out of the door and strapped it to my mono amp and smoked it from frustration. Anyway i never heard of moisture blowing speakers, is that common?

brewer_brewer Posted March 30, 2009 Report Share Posted March 30, 2009 check the polarity of your speakers. maybe you have the positives and negatives reversed on that one door.
