liftedranger08 Posted April 1, 2009 Report Posted April 1, 2009 I have 2 cerwin vega vmax 15s. They are 600 rms and 1200 max. I have 1 Elemental Design nine.1 on them. This amp puts out 1200-1300 watts at 1 ohm so the subs are getting around 600-650 rms. I havent had these subs very long but i bought them used. When i got them, they sounded and good and were loud. I built 3 different boxes for them and my final box is a wall that is 7.1 cubic ft tuned at 33Hz. This is the box that hits highs, lows and mids really good. My question is, what are some of the signs of a speaker that is about to blow? My subs are starting to smell real bad after playing for about 5 minutes, and they are also getting quieter then they were when i first put them in the box. Also, they used to hit lows real good, but now when they hit low notes, the speaker moves a ton, but no noise comes out and it also sounds like they are bottoming out but they didnt do that before. Are my speakers about to be shot, or is there anything I can do to fix it? Ive tried to tune the amp, but they only get worse. Thanks PS: maybe time for some FI 15s or DC 15s. :hairtrick: Quote 2000 White Ford Ranger 5" RCD lift 33x12.50 Mickey Thompson MTZs on 16x8 Mickey Thompson Classic 2s Euro Altezza tail lights 5% window tint Clarion Indash 4 Q Power 15s 1 Sundown 2000 1 DC power 300 amp alt(on the way)-soon to be 2 2 powermaster d925s batteries Second Skin Deadener Highs/mids amp-Crossfire 404 Door speakers-2 5x7 mb quarts and 1 5 1/4" black max up front, stock 5x7s in the rear Soon to Come: Lots of SA-8s 2 Sundown saz 3500s(possible 4500s) 5-7 d3100 batteries custom clamshell BNC 8s for mids undecided tweeters
brewer_brewer Posted April 2, 2009 Report Posted April 2, 2009 the sign that they are about to blow is the smell. when you car smells like cocaine turn it down. what amp are you using? you are most likely giving the subs a clipped signal if they are smelly like that.

liftedranger08 Posted April 2, 2009 Author Report Posted April 2, 2009 I have a Elemental Design nine.1. Its rated at 1200 watts at 1 ohm but people say it puts out more. For electrical, all i have is the big 3 upgrade, and 0 gauge from the battery to the amp and a stock alternator.

brewer_brewer Posted April 2, 2009 Report Posted April 2, 2009 do you an o-scope or dmm available to you? check to see if you're clipping how high are your gains and bass boost? if they are smelly its because they are getting hot. clipping is the most common reason. they should not even get warm with a clean 1200 watts.

liftedranger08 Posted April 2, 2009 Author Report Posted April 2, 2009 I do not have an oscope or a dmm. My bass boost is turned all the way down and my gain on the amp is halfway.

Zade08 Posted April 2, 2009 Report Posted April 2, 2009 The gain knob is not a volume knob. Try to match it to your headunit preout voltage as close as possible. I can actually tune mine by ear. I can tell when the subs start to get a clipped signal by the sound. Quote Vehicle: 2001 Ford Escape Head Unit: Kenwood Kdc-x592 All out for a rebuild. New shit coming in the next 30 days.

Zade08 Posted April 2, 2009 Report Posted April 2, 2009 Haha. I said the same thing. Went from 2 kicker 10s to 2 kicker 12s to 2 fi 15s now swapping with 2 sundown 18s. lol As far as power. Went from a 600rms audiobahn amp to a 900rms kenwood to an saz-1500d to an saz-3000d and now Im moving up to two saz-3500ds. lol. You cant say your going to do it big. Your just always going to do it bigger than before. lol Play with it. Get a couple steady bass tones out that really make the amp work and play them on repeat and tune it. When the bass starts to distort and sound like ass back the gain down a little until it cleans itself up. Quote Vehicle: 2001 Ford Escape Head Unit: Kenwood Kdc-x592 All out for a rebuild.

liftedranger08 Posted April 3, 2009 Author Report Posted April 3, 2009 Ok, thanks guys. Do you reckon i need to inevest in a better amp, like a SAZ 1500d or something so the subs get clean signal if i retune it and my current set up doesnt get any better?
