alright so I set my gains with a dmm. the front speakers have a weird smell coming from them after slamming for 15-20 mins... they are fairly new speakers just got them about 2 months ago. my only assumption here is that I am clipping the speakers but not quite sure why.. my amp does get kind of hot but it NEVER goes into protect mode. oldschool kenwood 25 rms per channel at 4 ohms. sqrt (25x4) of course is 10 volts. i set them exactly at 10 volts with a 1k -3 db test tone. the smell is not strong, I literally have to be near the opening to smell them but I can nonetheless. should i be worried about this or is this typical with 2-3 month old speakers? thanks yall

i dont think that has ever happend to me... all your connections and wires are good? nothing maybe touching behind the speakers and melting something.. ?

push on em and see if it is scratchy and also measure the coils on a dmm

25 watts.. really almost shoudlnt melt any voice coil... even stock lol
sure its not your subs? and if it your speakers, i've heard ppl suggest maybe excess glue but i'd still be careful cause i dont know how true that statement is, and if you clipped 25 watts badly.. wouldnt that equal almost 100 watts dc? or am i wrong?

I am POSITIVE it is not my subs. Like I said I can only smell it when I kneel down and look directly at the speaker through the grill on the door. I hear no distortion, the speakers sound great. i really don't know why I am smelling it.. maybe it is just factory glue but idk.. thats why i'm asking yall :)

well like i said still be careful, if you start to smell it turn it down, but if you have to get close tehn maybe its not as bad as it seems.. when i heat up my voice coils my whole car stinks

well is it adversly affecting the performance of the speaker? if not then i wouldnt be to concerned unless the smell gets worse.. it could be somthing as small as smelly water in there or something that got soaked with poopy stuff.... take it apart and find out!

this is what I am hoping for. thanks for the responses. it doesn't stink my whole car up at all.. like I said I have to be right by the speaker to smell it. maybe I am just over reacting and it isn't as bad as I make it out to be. f*** it, if I blow them.. time for me to upgrade to components anyway. about to get a new 4 channel amp and get rid of the kenwood too as soon as i get some more money saved up.

it is true maybe there is some corrosion somewhere, when my battery was covered in crap and i would run power through it, you could smell it like 25 feet away with ease... but them again that was alot more than 25 watts

i still wouldnt go by the suggestion of adversely affecting your speaker.. because it wont until it comes unwound.. and when that happens /speaker

Use a 1khz 0db test tone. The idea of using -3db test tones makes no sense too me. Even music recorded @ -10db can (& does) have transient peaks near the 0db mark. These transient peaks are getting clipped &/or your amp doesn't do the wattage it claims.

most of the time these peaks are less than a second long, though. a clipped signal wouldn't negatively effect a speaker at all if exposed to this greater amount of power for a split second. they should be fine. i think that a neg three db will work just fine, but if u want to be on the safe side, u might go with a zero. i wouldn't personally, but that's just me.

Your referring to music w/ dynamic range. Sad thing is, the majority of todays music isn't "dynamic". The industry is adopting your way of thinking.
Have you heard Metalicas new album, w/ tracks @ a constant -2 - Odb? Personally, I'll take quality over the extra bit of volume.
