Hello, I tried to install my self-amplified sub and its not working. I followed these instructions given in the package:

There are 4 connections necessary
for proper operation of the BA-1 00.
(See figure B)

1. 12 Volt (12V): Connect this wire to
a source of + 12 volts which does not
turn off with the ignition key. It may
also be connected directly to the
positive (+) terminal of the battery.

2. Ground (GND): Secure this wire
using a screw or bolt on a grounded
metal surface of the vehicle. Clean
away any rust, dirt or paint from the
surface to make sure a good connection
is made.

3. Speaker Input Positive (SPK +):
Splice this wire to the wire going to
the p.ositive (+) terminal of the
speaker that you have chosen
(sometimes indicated by a red dot).

4. Speaker Input Negative (SPK -):
Splice this wire to the wire going to
the negative (-) terminal of the
speaker that you have chosen.
This completes the wiring of the
BA-100. Re-check all connections to
make sure they are secure.

Is there anything that i could be missing since my sub doesn't work. All of the wires are connected to their designated colors. When I connect my ground wire to a metal surface of my car , the lock of my car lock themselves does this mean anything?

Thank you for reading and your help will be ver appreciated.

Find a different spot to ground it...

-------------
'89 Mercedes-Benz 300E
Pioneer DEH-5900UB
(2)RE Audio SX 10"s
(1)US Amps MD3D
3ft^3 @ 37Hz

Blowing up in a car accident doesnt worry me, as long as I'm putting out some major dB's when I die...
