GoHoMeUcRyBaBy Posted January 19, 2011 Report Share Posted January 19, 2011 Is it a bad thing when subs get warm? I have two dual 2 ohm 10" p3's wired down to 2 ohms running off a kenwood Class D mono power amp, 300w Rms at 4 ohms and 500 rms at 2 ohms. So im running about 250 rms to each sub. I have a gmc sierra with a stock alternator and piece of shit walmart battery that isn't that old.

Rebel4055 Posted January 19, 2011 Report Share Posted January 19, 2011 if they are getting warm that means either you wired them wrong, or you have the gains set WAYYY to high. Rest In Peace mother.

skittlesRgood Posted January 19, 2011 Report Share Posted January 19, 2011 all depends on how warm they get and how long its taking. if they are definitely warm then its probably because you are clipping a little. if they are just a little over room temp. then i wouldnt worry about it. If I answered you in a well mannered, informative way, you asked a good question or had a good attitude. If I was an asshole, you asked a stupid question or you had a fucktard attitude... or I was in a bad mood.

GoHoMeUcRyBaBy Posted January 19, 2011 Author Report Share Posted January 19, 2011 Well i live in az so its 54 degrees. I don't have a oscope or digital multimeter so i have to tune it by ear which i know isnt a good way, but its all i have for now The way i have them wired is Sub 1 + to + - to - Sub 2 + to + - to - Then a - from one sub to a + on the other and the other + and - to the amp Sorry if its confusing.. 2002 Gmc Sierra 4x4 2 10" dual 2 ohm p3's Custom box (34hz) Kenwood eXcelon 1800 watt amp Kennwood monitor Polk Audio door speakers Kenwood tweeters Boston acoustics rear speakers alpine 4 channel Link to comment Share on other sites More sharing options...

You might be running it at too low an impedance, which means the amp is putting out more than 500, which will be hard on the amp and subs. If you are sure that's not the problem, I'd check your gains. What head unit are you using? and what is the output voltage of the RCA? Are you A. using gains to compensate for low input voltage? B. Using bass boost, or any type of EQ, like Ipod bass boost etc.. C.Are your ground connections good? and are you using large enough speaker wire?....All of those things can lead to a clipped signal, which will cause the VC to overheat. And what type of box are you using? make sure your enclosure is the correct size and shape, or correct tune etc... If your enclosure is too large for the subs, it will create a free-air situation, causing the sub to bottom out/over extend, which will lower it's power handling capability. Also if you are using a ported box, you may need to adjust your subsonic filter, if u have one. 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

That would be 2 ohm, you have it wired correctly. Do you have access to a digital multimeter? if so, you can use it to meter the output of the amp, as well as check the impedance on the subs. If one of the VC is blown, it could be shorting, lowering the impedance... The sub might still function off one VC as well. It's all things to check haha 2009 Cobalt LT Pioneer Headunit 2x Pioneer 6 1/2 (stock amp) 2x Pioneer 1" tweeters (stock amp) 2x Pioneer 6x9 (stock amp 4x Pioneer 6 1/2 Pioneer GM-6400F Soundstream DTR 1700 R.I.P 2x Champion series PRO 12" subs 0 AWG Big 3, Stinger SP1700 battery To come: New or repaired DTR!!

My grounds are ok. I have 18 gauge speaker wire right now because its all i have for now. I made the box myself and its about 2.25 cu ft and tuned to 34hz. The amp doesnt have a subsonic filter, but it has bass boost, low pass filter, and infrasonic filter. The amp says its 1000w peak power. 2002 Gmc Sierra 4x4 2 10" dual 2 ohm p3's Custom box (34hz) Kenwood eXcelon 1800 watt amp Kennwood monitor Polk Audio door speakers Kenwood tweeters Boston acoustics rear speakers alpine 4 channel Link to comment Share on other sites More sharing options...
Rebel4055 Posted January 19, 2011 Report Share Posted January 19, 2011 Infrasonic filter is a sub sonic I believe. What is the low pass and bass boost at. Also if that infrasonic filter is a sub sonic do 2hz below tuning Rest In Peace mother.

It's all things to check haha I might be able to go to the audio shop near my house and borrow one. To check the output of the amp do i put it on the speaker terminals? and for the impedance on the subs i put it to the terminals with the wire in them? 2002 Gmc Sierra 4x4 2 10" dual 2 ohm p3's Custom box (34hz) Kenwood eXcelon 1800 watt amp Kennwood monitor Polk Audio door speakers Kenwood tweeters Boston acoustics rear speakers alpine 4 channel Link to comment Share on other sites More sharing options...

Also if that infrasonic filter is a sub sonic do 2hz below tuning My Input sensitivity is at 1 the minimum is 5 and max is 0.2. My LPF frequency is set to 150 Minimum is 50 max is 200. Bass boost is at 12 minimum is 0 max is 18. On my head unit i have everything set to 0. 2002 Gmc Sierra 4x4 2 10" dual 2 ohm p3's Custom box (34hz) Kenwood eXcelon 1800 watt amp Kennwood monitor Polk Audio door speakers Kenwood tweeters Boston acoustics rear speakers alpine 4 channel Link to comment Share on other sites More sharing options...
