Speaker problem???

[hskrbkr]

Although the problem is not ocurring now, I have a feeling it will come back. A couple weeks ago, my left rear speaker kept cutting out. It was most severe when I would hit bumps. Sometimes it would quit working all together. The problem would come and go.

Well, I put my HU myself about 6 months ago and reluctantly assumed that my wiring job was bad. I didn't have a chance to pull the HU right away. When I finally did have the chance, the problem had gone away but I wanted to check things out anyway.

I pulled the HU and tested the connections, nothing was bad. I even gave everything the shake test to simulate road bumps and it didn't have any effect.

I am stumped. It is working fine now, but there must be something wrong with it. Is that speaker blown? Will that cause it to intermittenly cut out? Anybody have an idea?

My speakers did the exact same thing when I had the stock headunit - except it was the entire right side. If I whacked the doors, sometimes the speakers would start playing again.

Then eventually all my speakers went out! You could hear static/hissing coming out of the speakers, so I figured it must be the headunit or the factory amp.

I'll guess I'll find out soon enough. I'm putting in new wiring to my speakers today, I'll let ya know how it turns out and if that solves the problem for me.

BTW.. I'm putting in some new pioneer or infinitys sometime within the next few weeks.. so I won't hafta stick with the stockers for too long.

did you bypass the factory amp? if not, you really should.

anyway, did you check the speaker connections in the doors?

I have not bypassed the factory amp. I used a part supplied by Crutchfield to continue using the factory amp, because I wanted to keep using the sub. I realize there is probably a way to bypass the amp and continue to use the sub, but I took the easier route and I don't think sound quality has suffered. If fact, I noticed a marked improvement over the stock HU even while continuing to use the factory amp.

I did check the connection to the speaker in the door. I wiggled it around and hit the door, but I could not replicate the problem. I even checked where the wires run between the door. Again, no luck.

What type of headunit do you have and what was the device called. Was it a LOC (line out converter). The problem might be in the converter.If you have a High power headunit (45x4 max)or highert some of the cheap converts will actually melt inside when driven hard.
The problem with most LOC is they have resistors inside that have to disapate alot of heat to drop the output down to a level the factory amp can use. The good LOC use transformers inside and work alot better.

ok, I got done installing my pioneer this afternoon, and it works perfect. I didn't even run new wire, just used the existing stock wiring (for now) by bypassing the amp. The speakers don't cut out at all, at least up to volume 25 (goes up to 40).

So, bypassing the amp worked for me, no more speaker problems.

THE speaker god frowns upon u. Ye must deliver to thee, the Stock amp and then destroy it.
And once again the Gods of speakers will smile.

I have a Bluapunkt HU that is 40x4 peak output. I can't remember the name of the piece (LOC) I got from Crutchfield, but it cost $50. It seems like a good product though. It allows the output to each speaker to be adjusted - up or down - using a screwdriver. For the speaker in question, I adjusted the output up pretty far and it didn't make the speaker act funny. I guess that line out control piece could be the problem, but it seems to be working fine.
