Ok first I forgot to warm em up. Second I had em on loud with them being cold.

I was just setting up my system again in my new car, setting the gain and such. I have my 2 infinity reference 12s wired at 8ohms to my jbl 1200.1 so they get 150 rms a piece. So they play nice and loud for about 5 minutes while im tweaking the gain and lowpass and such. Now there is a squeaking noise coming from either the subs or my trunk. The louder I have em the louder it squeaks so i think its the subs. I have a 4 year warrenty so its no big deal. I just got over excited lol

But is that what it sounds like, like they about blown? It sounds like a windshield wiper squeak. Unless the bass is making a part of my trunk squeak, but i doubt it since it didnt happen right away.

Hay try this, its an easy way to see if the coil is out of alignment (blown speaker / tore spider / so one) CAREFULLY push on the CENTER of each sub. If you here what sounds like a scraping sound, then that is probably your culprit.

im pretty sure one is blown, but im gonna have to pay more money to get new ones at CC so i think im gonna get instore credit, buy somthin else and then get 2 DVC brand new off of ebay.

The guy said ill have like 200 bucks store credit but im sure i wont because i got these speakers at a deal where i got 2 and a box and some other shit so it will end up being like 100 or 150 then ill have to add 70 for the new ones. If it is 200, id just add 20 and get new ones
