Karkov Posted November 10, 2013 Author Report Share Posted November 10, 2013 and the HU HPF set to 125.What does this mean ??Amplifier should be completly fullrange and only cut off on the low end ... Sorry, trying to keep up with the posts in thread. Took a screen shot of the HU and the HPF setting on the HU that I was talking about being at 125. When the amp was set to AP (all pass) the mids seemed like they would bottom out so I had the amp set at HP (high Pass) 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

Karkov Posted November 10, 2013 Author Report Share Posted November 10, 2013 Doesn't this keep happening to every comp set you have hooked up so far? Maybe the amp is the issue? Completely different amp. Previously it was the T1000-4ad on the 2 T3 sets, now it's the T600-4 on 2 CZ sets. 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

rockFord_Expedition Posted November 10, 2013 Report Share Posted November 10, 2013 Before they blew, did they sound ok? Sounds like the tweeters are playing too low, like they are getting signal they shouldn't, almost like the crossovers were wired wrong from the factory. Are you over powering the shit out of them? Next time I would check resistance at the input terminal of the crossover with the mid and the tweeter connected, but without being connected to the amp. Sorry if this has already been asked, but are you using the HPF on the AMP (I know you are using the one on your HU but that only blocks below 125hz)? Ok NM I see you said you had it set. Do you own, or know anyone with a cc1? If not, you can use your DD-1 to see if you can detect 40hz or 1khz signal at the tweeter output on the crossover. I would imagine neither should be present.

rockFord_Expedition Posted November 10, 2013 Report Share Posted November 10, 2013 The little switch in the middle of the xovers, is that for tweeter att? Or something else?

Karkov Posted November 10, 2013 Author Report Share Posted November 10, 2013 Before they blew, did they sound ok? Sounded good before the crossovers melted, not sure if the tweeters blew. Sounds like the tweeters are playing too low, like they are getting signal they shouldn't, almost like the crossovers were wired wrong from the factory. Are you over powering the shit out of them? Not overpowering the shit out of them, in theory not over powering them at all. Doubt stuff was wired wrong from factory because all 4 crossovers look melted on the tweeter side so I know it's a mistake on my end. Next time I would check resistance at the input terminal of the crossover with the mid and the tweeter connected, but without being connected to the amp. I guess in hind sight I sure could check the resistance at the input of the crossover with the amp disconnected, I know what you are saying and I guess I just didn;t think i needed to since i didn;t expect to have problems.

Ok NM I see you said you had it set. =) Do you own, or know anyone with a cc1? If not, you can use your DD-1 to see if you can detect 40hz or 1khz signal at the tweeter output on the crossover. I would imagine neither should be present. I own a CC-1 but had not hooked it up yet. Next time I will do it three times before powering it on though, lmao 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

White Lightning Posted November 10, 2013 Report Share Posted November 10, 2013 Ok ... here's my guess ... I'm assuming that you are cranking these bad boys up so that they can keep up with the sub bass and sound good in the process ... My guess (from the evidence presented) is that you are overworking your amplifiers ... I know, they should handle this with no problems, but ... something is wrong and the same exact thing happened with other components and another amplifier ... This is why I NEVER use anything but 2 channel amplifiers. It has been confirmed that high end (mids and highs) amplifiers work alot harder than sub amplifiers ... In Multi channel amplifiers, their power supplys are just not strong enough to handle the job at hand ... I'd be willing to bet that if you took one component set (in the kicks would be ok) and hook them up with a 2 chamnnel amplifier and see if things don't work better for you ...

Big Big possibility of what you say. You know 100000000x more than me, no wait, double that. Dude, thanks so so so so much for the info and help.

Still kind of processing what you said....... ok, for the time being what can I do with the equipment I have? IF* the crossovers are blown I will have no choice but to run active but then again I truly do not want to blow more stuff. When you say trying to sound good in the process and over working the amplifiers you mean gain too high? In the future is that what you think *could* have saved me this time around? 2007 Chevy Tahoe (SOLD) 12 ~ FI Audio X series 10" w/BP option 2 ~ DC Audio 5.0K @0.67 3 ~ DC Audio 5.0K @1.0 2 ~ PPI 3 way sets (not installed yet) 1 ~ RF T400-4, 1 ~ RF T600-2, 1 ~ RF T600-4 4 ~ CT Sounds 5.25" Strato comps (rear fill only) 1 ~ XS Power D4800 1 ~ XS Power D3400 8 ~ XS Power XP3000 160 stock alt, Mechman 370 Elite, 185 DC Power 320+ Sq.

03 Xtreme Fosgate Posted November 10, 2013 Report Share Posted November 10, 2013 I'm sorry but I can't see it being that amp being over worked,I have the same amp along with 2 other 4 channel RF amps and have no issues with any of them. This is just crazy,I doubt it's voltage since you're electrical is strong so I'm kind of lost. Hope you get this worked out BUILD LOG-http://www.stevemeadedesigns.com/board/topic/179004-03-s10-xtreme-ext-cab-rf-build/ PHOTOBUCKET- http://s1354.beta.photobucket.com/user/03XtremeFosgate/library/truck%20audio%20rebuild Link to comment Share on other sites More sharing options...
