Hi, I installed some after market door speakers and I get this loud noise coming from them. Sometimes I hear a ground noise but mostly it's just a loud sound of nothing. All I did was splice the wires that were hooked up the bose speakers and ran those to a hi/low converter and into my amp on both sides. I think it might be conflicting with the bose system but I'm not sure. Is there anywhere else I can splice the wires without going through the bose amp? I want to retain my bluetooth and eveything. HELP!

 

high lo converters are made for subs not after market speakers - its so you dont have to tap into the back of the headunit.. you have to take off the hi-low conveters and soder up ur connections and do it right .. take the sht bose out and put some real speakers in .. and wire them up right

 

so your running aftermarket speakers on the bose HU or?

 

yes, the stock headunit. How should I get rca outputs then? or where do I run the wires from my amp to?

 

to use aftermarket speakers wit a stock amp is kinda pointless.. my suggestion would be is to take the highlows out.. resoder the wires .. go to circuit city or bestbuy and invest in a nice 4 channel amp .. you can get rca outputs if u dont run it thru the bose amps.. but u need an aftermarket amp in the back of ya car .. ur powering speakers off ****ty amps and ur juss takin the lows out of the sound and thats y u are gettin loud noises

 

First you might want this in the "audio section" to get the experts on it.

Sounds (no pun intended) like you disconnected the output of the Bose amplifer that was going to the Bose speaker, and connected the output of the Bose amplifier to your own aftermarket amplifier-then to your own aftermarket speakers. Correct?

If so, he does need a "hi/lo" converter. Sounds like you have a grouding issue that may or may not be compatable with the bose amplifier system. If the Bose amplifier ground is connected to the chassis then so should your new amplifier. Maybe you have a bad amplifier. Keep in mind you're only going to get lower frequencies to the door speakers (less than 3KHz) seeing as tho the Bose is a component system. The frequencies above 3Khz (roughly) will be going to your tweeters.

Reconnect your original system back up on one side to make sure it still works without the aftermarket amplifier (leave your aftermarket speaker in the door and hooked up). Got music without noise? If so, it's obviously between your aftermarket amplifier and the associated connections. If you still have noise then connect the Bose speaker back up. Still the same. If so, you somehow messed up your system.

Be sure to report back your results and we will help you nail this thing. Best of luck.

 

A subwoofer is indeed a speaker (just a bigger one optomized for lower frequencies). Most subwoofers ARE aftermarket. A "hi/lo" converter isn't for speakers-it's for amplifiers.

A Hi/lo converter allows for a high output of a amplifier to go into the "suppose to be" low level input of another amplifier. It simply reduces the the audio signal so that it does not saturate the input of a amplifier.

A headunit often times has a built-in amplifier (usually aftermarket). If it does not have a preamp level out it too will need a "hi/lo" converter between it and another amplifier (regardless of rather it's running a Subwoofer or regular speaker).

 

I don't know what to do then. The noise sounds like a light static. I don't think it's my ground because I grounded it to my chassis. I tried to splice the wires that were running to the bose amp in the back but that didn't work. I NEED HELP!!

 

oh and yes I have an aftermarket amp. I ran my seperate wires from each door and speaker straight to the amp. Then, I ran wires from the old bose speaker's wires to my hi/low converter and into my amp through RCA's. I thought that maybe it was because it was still going through the bose amp that made that noise so I tried to disconnect the wires from the amp and hook it straight up to the hi/low converter but it hasn't been successful because I don't know which wire to cut.

Sorry if you don't understand what I just typed lol
