Need Help Install Aftermarket Amp

[NEWATTHIS1]

IM JUST BOUGHT A 93 GS300 AND I WANT TO INSTALL AN AMP AND ANOTHER SUB, CAN I STILL USE THE FACTORY AMP AND FACTORY SUB ALONG WITH THE NEW AMP AND SUB IF SO HOW CAN I INSTALL THE NEW AMP AND SUB. I WANT THE FACTORY AMP TO POWER THE STOCK SPEAKERS AND THE NEW AMP TO POWER JUST THE SUB

your best bet is to just run the power lines remote etc..to the trunk and then get a good set of line level convertors to plug into the new amp and then you can power you new sub.if you dont know what line level convertors are let me know and i will explain. ;)

I used the converters in a previous setup I had and they were fine.

For some reason when I used the same converter in my SC300, there was a lot of engine noise.

I tried a ground loop isolator but it didn't help.

I then went and bought a Rockford Fosgate amp and just fed the high input lines going to the stock sub right into the high level inputs on the amp.

Now it sounds crystal clear and beautiful.

I now highly reccomend Rockford.

It doesn't draw nearly as much power as the Kenwood I had used to and it gives more power.

As for the power cables.....run the positive from the battery through a rubber grommet in the firewall.....find a negative somewhere in the trunk.

For the remote wire, unless you want to remove your headunit (pain in the ) and stretch it all the way back, there is a reliable 12V source coming into the CD changer.

I found it using a 12V tester.

It gets fed 12V when the car is on which I decided is fine for me (whenever the car is on, the amp turns on)

I think that should do it.

Feel free to ask questions and I'll try to stop by this board more often. :D

WHAT IS A line level convertors AND WHERE CAN I GET ONE AND HOW DO I INSTALL IT?

[SPORTcoupe300]

A line converter is a small device that converts high level input into low level RCA.

Your speaker receives two small wires (24 gauge?).

In the wires the sound is amplified to push the speaker.

For the RCA going into the amp, you need low-level, non-amplified input.

That's where the converter does it's job.

Looks like this.
