Amplifier problems

Hey guys I just purchased a power bass amplifier for my 2000 toyota tacoma, the issue I am having is when I turn my truck off the amplifier stays on. I have the remote wire hooked up to what a thought was a accessory wire (12v blue wire) just in the door by the circuit board and I'm wondering if any of you would know what I am doing wrong.

I tried hooking it up by my head unit but i think the remote wire is faulty because it doesnt read anything when i test it and the amp doesnt turn on when i hook it up by my deck.

 

Ive never wired an amp before, but I imagine you would want to tap into an ignition wire so that it only has power when the Truck is on. You can fuse tap into the ignition fuse in the cab if thats the case

welcome to TW btw

 

Your aftermarket head units stereo has a blue wire just for this (remote turn on), have you tried using this?

Other amplifiers are signal sensing, could try changing the settings or even the input from RCA to the speaker level inputs.

Last alternative would be tapping into the ignition wire which is the 7.5A fused tap in the interior fuse box.

 

I recently added a powered bass to my truck also and had to get an adapter that plugs in where the main head unit plugs in. The original head unit plugs into the back of that plug. This added a "signal" wire for the bass unit.

Do you have a stock head unit? If so, you must have an adapter to add the signal wire.
If not, is there a setting to change that toggles the signal on or off?


Tapping into a blue wire that doesn't have power when your truck is off is not the same as connecting to the signal wire of the head unit. It is probably a specific voltage that is needed to turn your bass unit on, not just 12v on the signal wire.

 

As others said. You have it wired into a always hot wire.

 

Mine is wired directly to the battery but only comes in when the truck is on because of the signal sent through the wire from the head unit.

Here is the adapter I used for my 04 Tacoma:

The blue wire on the right side of the plug is the on/off signal wire.

 

Since you are going through this anyway, you might want to consider mounting a toggle switch on the blue wire to the amp so you can switch off your amp to save your battery for starting if camping or parked for a few hours etc. I always do this when adding an amp these days.

 

Find the power wire that the deck uses to power on, and splice into that. Doesn't really matter which one, but you just need one that gets 12v when you turn the key to "accessory" (i.e. the radio turns on).

The primary power for the amp should come direct from a fused link to your battery.

 

Yes I have tried the blue one up by my head unit and it didnt work I'll play around with it more later and I'll let you know if I figure it out, thank you for your suggestions.

 

Awsome I'll give that a try, thanks
