What is my problem/ Bad speaker maybe?
Could my speaker be blown?
Kenwood Excelon 869 and 759 HU (Both are referred to in the the story 759 at the beginning) Directed 500 Amp Invinity kappa 6X9 3ways (653.1 I believe) OK here's the problem. My old deck fried it's preamp RCA cables so everyone was saying that I had a bad ground, (which I really doubt since, I have it grounded to a metal bar in my dash, plus if it was a bad ground I dont think the HU would even play, I wouldnt think, also it was making a loud screeching and feed back noise like on a bad PA system. In the mean time while I was taking my deck around I installed my old stock deck, Thats when I noticed my rear speakers may have had a problem. It seems as if they would play when they wanted with no rhyme or reason, but when they werent playing I would get aloud popping sound form them, mostly when I go over bumps. well oneday I was washing my car and had to go in the trunk a few times, I noticed whenever I would open the trunk the speaker would starts working for a few mins then go back out again say when I drove off and hit a bump or something. Well I got my new deck a few days ago and installed it last night, I used brand new RCA's to make sure my old ones were bogus, I Hooked everythng up and it soundind fine I drove it around the black and the feed back noise came back. I unhook the rear channel RCA's and continued my drive last night and frove to work this morning (about 35 mins) and no problems at all, so thet leads me to believe it is the rear speakers that are having a problem. could they be blown or one of the coaxles have gone out or a wiring problem or what? -- Wmaharrisjr ------------------------------------------------------------------------ CarAudioForum.com - Usenet Gateway w/over one million posts online!

What is my problem/ Bad speaker maybe?
OK here's the problem. My old deck fried it's preamp RCA cables
How?? so everyone was saying that I had a bad ground, (which I really doubt since, I have it grounded to a metal bar in my dash, Do you know that this metal bar is an adequate ground? plus if it was a bad ground I dont think the HU would even play, It would. I wouldnt think, also it was making a loud screeching and feed back noise like on a bad PA system. Which is a typical symptom of a bad ground... In the mean time while I was taking my deck around I installed my old stock deck, Thats when I noticed my rear speakers may have had a problem. It seems as if they would play when they wanted with no rhyme or reason, but when they werent playing I would get aloud popping sound form them, mostly when I go over bumps. well oneday I was washing my car and had to go in the trunk a few times, I noticed whenever I would open the trunk the speaker would starts working for a few mins then go back out again say when I drove off and hit a bump or something. Sounds to me like one of the speaker terminals may be grounding out somewhere. Maybe on the trunk hinge? Take a look. Well I got my new deck a few days ago and installed it last night, I used brand new RCA's to make sure my old ones were bogus, I Hooked everythng up and it soundind fine I drove it around the black and the feed back noise came back. I unhook the rear channel RCA's and continued my drive last night and frove to work this morning (about 35 mins) and no problems at all, so thet leads me to believe it is the rear speakers that are having a problem. could they be blown or one of the coaxles have gone out or a wiring problem or what? Blown speakers won't whine. Check the installation. If nothing appears wrong, you'll have to isolate components until you figure out what the faulty device is. |

Take a 9v battery to the speaker and see if it jumps out... Also lightly
push on the speaker cone and see if you can feel a rub... If you dont hear a pop with the 9v, its gone... If you hear a rub you've fried the voice coil but it still wants to work... my suggestion is, (if you have subs) put a 100Hz high pass filter in line with each of your interoir speakers to protect them...
