L7 retrofit

deepsrd · 01-26-2016, 04:53 AM

Hi,

Need some help..

i did my L7 retrofit waaay back when.. ok 3 years ago..

I have recently replaced by battery, and it seems the battery is draining faster than it should (90Ah)
(I have ABS lights on occasionally, and today got 'No acoustic tones' message)

I had initially wired my amp directly to the positive terminal.
Would this cause problems?
if I had to rewire it, what would be the best option?

Thanks in advance.

this is factory option for individual amplifier, which is almost similar to L7 amplifier
so you might have some problem with amplifier
may be it is water damaged

Thanks!
I will check for water damage..

However, to answer my own question, the power cable should be connected to X10209 connector on e9x cars.
