Hello, I just bought a brand new kicker ds460 for my rear speakers and i also recently installed them. The problem is that it keeps on distorting even on mid to low volume everytime i turn up the bass. I tried bypassing the stock amp and still no luck. Please help

p.s. Mods i know this is the wrong forum to post on but there is more traffic out here. Please don't move my thread

ok so i did a little more testing and now its the left rear speaker only distorting. Also when i move tap the deck around, (my deck is not really secure btw and also when i installed it, i did not use any adapters. All i did was cut the stock connectors and just matched the wires to the other wires of the deck. Kinda ghetto i know.) it sometimes fixes the distortion but after a few seconds, it distorts again. Could it be my deck or the wires behind my deck????

Toby Broadfield, where are you?.lol

Couple things:

How is your radio grounded?Are the RCA cables plugged in nice and tight at the radio and amp?What if you switch the the left and right RCA's with each other at the radio?.... does it then make the right rear speaker distort or still the rear left?

Get back to me.

I'm sorry if I sound like noob but please bear with me on this one. I don't think my RCA cables are plugged in since the only wires that i messed with was the wires from the deck that i spliced and taped together with the wires that came in with the pioneer deck.

Also when i first installed both speakers, both were distorting and then my dad and I tried to bypass the factory amp by just simply wiring a wire from the deck straight to the rear speakers and to our suprise, it was still distorting.

Then we gave up and just rewired the speakers back to the factory wires (green,red) (pink, purple) i believe it was at the trunk.

The only thing is that if we put the new speakers to the front (w/o any speakers in the rear) it doesn't distort at all, so we elimenate that the speaker might be broken.

So right now, we put all the speakers back in place and only the back left distorts and sometimes doesn't work at all! so i'm guessing that it might be the wires behind my deck or something b/c when a tap/move it, it makes the left speaker work produce sound but with distortion at a certain amount of volume/bass

sorry for taking your time reading this

i was under the impression that speakers don't actually create distortion they just play it. what i mean is the signal is distorted before it gets to the speaker, ex poor ground or miss wired. you should def secure your deck and get it grounded thats a big plus right there.

I tried grounding it and still no luck. Also it only gets distorted when u turn up the volume and bass.

try hooking up your new speaker to different channels from your deck. instead of having it in the rear, wire it to the decks front right or left channel. i think you have a bad deck, or bad speaker...or possibly some wires touching. when you do any wiring, you have to absoultly make sure you secure everything and at least solder the connections.

Yeah that's what i did. I connected my new speakers to the front to check that it's not broken. It played really well without any distortion whatsoever so i think it's my connections at the back of the deck.
