01VWGREENMACHINE Posted March 1, 2012 Report Posted March 1, 2012 call me a noob if 90% of you already know this but i couldn't find anything about it on this site or the net so here it goes. I'v been beating my self in the head. I'm blowing these tweets with in the first week of installing them i have gone threw 6 sets of tweets. (yes i used the dd1 and the cc1 to get everything set right) running them off a t400.4 so only 76 rms per channel at 4 ohms so i knew i wasn't over powering them and no distortion yet I'm blowing them really fast. so anyways long story short i called rockford fosgate and they told me that when you have them set up to a single amp and have them set to all pass the bass loaded songs will go threw the cross overs and blow the tweets for the simple fact they cant handle those sound waves. (i though that was the job of the cross overs to filter out the sound waves for those speakers but i was wrong according to rockford fosgate) rockford is switching me out with new ones so no worries just annoying and figure i would give anyone else the heads up rockfords recommended settings are as follows switch crossovers to bi amp and run the tweets off the front channels and the 6.5 midbass off the rear channel (besides this is better for the rf amp users out there on the t series 4 channel amps have the bass knob option but it only controls the rear channels) thus solving my problem and possibly someone elses!! http://www.stevemead...f-system-build/ 2001 VW GTI with a 1.8T motor BIG 3 Pioneer AVH-4200DVD DOUBLE DIN HEAD UNIT 6 - 4 VOLT PREOUTS RF T1500-BDCP (running at 2 ohm) RF T400.4 RF T1 D212 x2 (in ported box) RF 1/0 TO 4 GAUGE distribution block x 2 all stinger wires 200a alternator (SINGER ALT) RF T2652-S (6.5 MID BASS AND 1" TWEETS in front and rear) KINETIC HC 800 BATTERY (Front) KINETIC HC 1200 BATTERY (BACK) 120ft of 1/0 stinger blue and clear matt 20ft of 4 gauge stinger blue and clear matt 30ft of 8 gauge stinger blue and clear matt 100ft of 12 gauge stinger speaker wire black
teamace24 Posted March 1, 2012 Report Posted March 1, 2012 Thats weird when you set the amp to full range the external crossovers that came with your comps are supposed to block that bass going to the tweeters, in my experience they have anyways. 1st Setup(SOLD):2007 GMC YukonPioneer Avic F90bt Audiocontrol Epicenter2 Audioque SDC2.5 15 subs8.7 cubes at 37hz build DONEAudioque 1200d (Audioque 1200d Sold, similar performance to my ap1500)Diamond Audio Hex 6.5 Mids n TweetsCerwin Vega Exl 400 4 channel Bridged(also have MTX 4004 not being used)1 Run of power Knu Fleks 4 Gauge2 Cheap stock Battery setup2nd Setup (SOLD):2007 GMC YukonPioneer Avic F90bt Audiocontrol Epicenter2 15 Kicker cvx (maybe two SA 15 in future)7 cubes net tuned at 34hzAlphasonik Old school 1600rms (ap 1500d sold GREAT Budget amp)JBL 6.5 Power Series Components, Infinity Kappa 6.5 3 ways, and 2 Kicker KS Tweets (LOUD)Cerwin vega exl4001 run knu Fleks OFC 0 gaugeBig 3 done1 Odyssey 1500, 1 optima yellow top d31
TeamHT Posted March 1, 2012 Report Posted March 1, 2012 Funny...not once have I any issues with the multiple T2652-S comps or tweets installed. Tell me...does this smell like chloroform to you?

bobobass Posted March 1, 2012 Report Posted March 1, 2012 Crossovers do not 100% filter out frequencies. Most crossovers will attenuate a given frequency at 12 db per octave. That means given enough power, you can send damaging low frequencies to your tweeters. If your amp has a high pass filter I would turn it up as most components are not made to play anything under 80 hz. 2000 Subaru outback 2.5l Head Unit: Pioneer deh 4300ub front stage: tbd subwoofer: Stock Fi Q 18" amp: Audio que 1200d

neuspeedescort Posted March 1, 2012 Report Posted March 1, 2012 amp on full range - check passive crossovers - check active crossover on deck - check yes passive crossovers normally do there job but it never hurt to have a back up plan. i normally run my active setting on the deck just below teh midbass cut off of the passive unit. its a little insurance. for the mid driver. however i have never seen an issue with a tweeter. if you have blown them up then you have had to hear them distorting. a dd-1 and a cc-1 will not stop stupidity. not saying your stupid just saying there is a point where those units can't save the day.
