I just finished re wiring my high level inputs for my self amped bazooka after the Bose Amp. I tapped into the wires right at the Blue Plug (Pink, Violet, Black/Blue, White/Blue).

After having the radio on and then I power down and shut off my car, my sub starts to play a sustained bass tone and the amp does not shut off because I think the auto turn on via the high levels is still getting a signal and thus not turning off the amp. But when I open the trunk, the sub stops playing. But when I close the trunk it starts up again.

The only solution I have found is to disconnect the inputs to the rear 6x9 woofers.

Anyone have any idea what's going on?

 

You think correct. Any movement in the rear speakers can keep the amp on. Subs start to move, speakers move more..... you get the picture. Open the trunk, the subs don't move the speakers, amp shuts off, all is well.

Set the amp up to turn on w/ the "remote on" instead of the "signal sense" and it should work fine.

Fore more detailed reading, look back a week or two and you will find a couple of threads w/ the same issue.

 

I think that there must be a short somewhere, but i second the use of remote in instead of signal sense. Check your wiring and make sure nothing is connected to something it shouldn't be.

 

juskilntim - damn the answer was so simple and makes complete sense. I turn off the stereo. I get out and close the door. When the door closes it momentarily compressed the air in the car, causing the rear 6x9 to move. The moving cones hence induces a current into the wires, thus turning on my Bazooka that is wired to automatically turn on with signal. The sub produces a thump which them moves the 6x9 cones again and the signal and it just cycles on and on....

Okay but now I will have another problem. When I wire the remote line with an acc line (cigarette lighter) I get a turn on thump when I turn on the car. Is there something I can do to get rid of that?

 

I am assuming that you ran to the accessory plug in the center console. If not, try that. Also try turning your volume all the way down before start and see if that helps.

Turn on pop can be caused by an amp turning on before or after the source. It is more noticeable in cheaper amps, so it could just be inherent to the Bazooka's Amp, especially if you have the gains way up.

Several companies make devices that delay turn on of the amp or the pre amp to help eliminate the pop. Try this to see if either will help:

1. Disconnect your remote turn on wire, start the car, then plug in the remote turn on wire. Note thump compared to normal.

2. Jumper remote turn on to the power wire (so amp is always on) then start the car. Note thump compared to normal and #1 above.

If it was quieter either way, you know which module will help you. It will pobably (and hopefully) help by delaying the Bazooka that way you don't have to delay turn on of the bose amp. Also, check your ground just for the heck of it.

Good Luck. Let us know.

Okay I'm just updating this thread since I solved my problem with the amp turn on sound yesterday.

To turn on the amp - remote lead - I tapped into the pink/black wire from the blue harness plugging into the stock Bose amp under the rear deck. Doing so provided the perfect remote turn on signal and it also got rid of the popping I was having when plugged into the cigarette lighter. Another plus with this location is that it's closer to my Bazooka and the wire was easy to route around.

Now I have both rear deck speakers working, my Bazooka Self Amplified sub turns on without using the auto turn-on circuit and without any popping, and no susstained bass notes when the car is turned off. Perfect install!

 

Congrats!

 

good work.. and not to sound like a d1ck, but did it take you 3 months to do that? what did you do in the meantime?

 

I tried this yesterday, and I have a few things to add. Hook all your components to the pink/black lead. I had it wired to my LC7's remote in, and my amp connected to the remote out on the LC7. I still had the dreaded turn off thump. Re-wiring to run both the LC7 and the amp off the pink/black wire directly, has silenced the thump completely. If you have several components, it may be wise to hook the pink/black wire up to a 12V relay triggered by the pink/black wire.

 

LOL.

For three months I was just using the auto-turn-on feature, so no thumping but I couldn't plug in the rear deck speakers because they would turn on my Bazooka on if they moved slightly (inducing current into the auto turn on leads) creating a sustained bass tone.

For three months I listened to my system with only the front speakers and my sub - which was fine IMHO.

Anyway, to anyone connecting up a Bazooka or similar system, I don't think you can get any safer and trouble free than connecting it up as I described in this DIY - because I've tried every other configuration and this is the best sounding and reliable.
