doughboi916 Posted August 11, 2016 Report Posted August 11, 2016 whats up guys.. i have a set of DLS components in my truck,had them for years and recently just installed them back in.. they have been playing flawlessly until last week. blew 2 resistors and a capacitor on both sides? all the same resistors and cap? i dont know what could have caused this? they can handle 100rms and im running 75rms@4ohms to them, the gains are set less then half and my voltage doesn't drop below 13.7ish? i ordered the resistors and caps off parts express all of the same specs soldered them up and they work good but after about 10 minutes of play the resistors i replaced get really hot, like hot enough to burn your finger. could it be that the rest of the resistors are damaged too and adding a big load on the ones i replaced? the parts i replaced on each side 1x 5w 7.5ohm resistor 1x 5w 2.2ohm resistor 1x 12uF 250v cap i used a Dayton of the same spec your boy NEEDS HELP! im stumped
ShadeTreeMechanic Posted August 12, 2016 Report Posted August 12, 2016 You will need to set your gains correctly. Search for DD-1. How much power are you putting into them? The mode of failure for a resistor is to open. A hurt resistor will not cause amperage to go up. The resistors getting hot is normal. Burning out is not. Set your gains properly and it might not be a problem any more. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
doughboi916 Posted August 12, 2016 Author Report Posted August 12, 2016 thanks for the input! its just odd to me ive never experienced a crossover burning out on me like that.. the cap and resistors literally blew up! the ceramic coating on the resistors were black and burnt on oneside and when i desoldered them the coating crumbled apart and the caps blew all the guts out.
ShadeTreeMechanic Posted August 12, 2016 Report Posted August 12, 2016 Back in the day before bass blockers were invented, I would get caps from radio shack for my 6x9s. They would pop like a firecracker when they went out. lol 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon)
Karkov Posted October 8, 2016 Report Posted October 8, 2016 WTF^^ yes, set gains correctly. Also, too much power can cause that. I have had the same thing happen to me, RF, Crescendo, etc.....but I am a noob so take that for what it is...... 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.
