supremeaudio13 Posted July 2, 2011 Report Share Posted July 2, 2011 Installed the DC 175.4 in my vehicle as of 2 days ago and everything seemed to be working good. Today it all of a sudden cut the music and went into protect, I felt the amp and it was pretty warm. My voltage is good (power and ground) the remote wire is giving a good signal. My rca's are legit. Im just asking for your guys input on the matter. I know I remember reading the manual a while back and it mentioned the receiver DC current can only be 4V... My Pioneer 5200DVD that i just sold had 4V pre-outs but I switched it out for my older (6 year old) Pioneer Premier DEH-P780MP. It has a 16 band EQ.. blah blah blah and I know the pre-outs are 5V <<< Is this the cause ? Thanks guys... Quote Link to comment Share on other sites More sharing options...
bre2ts Posted July 2, 2011 Report Share Posted July 2, 2011 did you check to see if you were sending a clipped signal? a clipped signal can cause the amp to heat up and cause it to go into protect mode Quote Feedback 1 | Feedback 2 you win some, you lose some Link to comment Share on other sites More sharing options...
supremeaudio13 Posted July 2, 2011 Author Report Share Posted July 2, 2011 Honestly I just tried it not too long ago, amp was cool.. I turned the volume to 14 and it shut off again. Gain is like 65%. Volume goes to 62 but I Never turn it up even close. I dont have any way for checking the clipped signal.. Ill have to get that new SMD invention O and each channel is only at 3.8 ish ohms. Running 8 ohm Selenium Mids and Super Tweets. Quote Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted July 2, 2011 Report Share Posted July 2, 2011 warm amp.... hmmm..... all i can think of is clipping bad.

JZeFF Posted July 2, 2011 Report Share Posted July 2, 2011 (edited) Its hard to believe that he was able to kill an amp in 3 days, especially with good electrical (and not being a dumbass to the gain or volume)... I had a problem with some other amps when i gave them higher voltage than recommended from a line driver. Overheated almost instantly... If no one gives a better suggestion, i would try to swap your old HU back in for a try. Unless of course its already too late... Then you may be out of luck.

Rainman215 Posted July 2, 2011 Report Share Posted July 2, 2011 (edited) Its summer time... Who's amp isn't warm... Yesterday the amp was fine at "full volume" and today it's not even though you changed nothing? Maybe you blew a mid or tweet... Or just have them hooked up wrong. How exactly do you have your drivers wired? Edit: reread first post... You probably are clipping bad seeing as the gain is the same but your pre amp voltage is higher... It's probably because of your HU.

If no one gives a better suggestion, i would try to swap your old HU back in for a try. Yeah.. I just tried again, gain on the amp was 25% and went into protect again at volume 18.. The mids are honestly as loud as if you were talking in the library lol. No bass boost B.S. ... No other sub amp or anything else conected. Ill try swapping units like you said if nothing else has a better sug. Quote Link to comment Share on other sites More sharing options...

It's probably because of your HU. No it was never at "full" volume but it was working fine. Ill re-check my wiring, But Im pretty sure its correct and all drivers are in working order. O and the mids are selenium and so are the super tweeters. I have the drivers wired together, final impedance before rise or anything is 3.8 on the different channels.

Rainman215 Posted July 2, 2011 Report Share Posted July 2, 2011 You have your mids and tweeters wired to the same channel? It must be because of the higher pre out voltage. Get a new HU.

No the Tweeters are totally seperate. Quote Link to comment Share on other sites More sharing options...
