I have a Crown XLS 202D Power Amplifier for my 6x9s. What kind of pre amp do I need?

I thought you were set on using your car audio head unit?

That Crown is 200 wpc into 8-ohms, so I hope your speakers can handle the load (or better yet, be careful with the volume knob!)

Yeah I was using the car head unit. I had wired as the input to the Crown Amp and I had the 6x9s wired at 8 ohms hooked up to the output. And when you powered up the amp they sounded like crap. My friend told me that the cd player is giving out a weak signal. I remember somebody on here telling me that I would need a pre amp.

My guess is it doesn't sound like crap because of the HU, it sounds like crap because you're trying to use car audio 6X9's inside. I tried to warn you about that.

Not really. When the 4 6x9s are hooked up directly to the cd head unit they sound awesome. Its just when I put the amp on them they sound like crap.

Uh huh. A Crown professional amplifier - even the bottom of the line model you have - is much higher quality than any amp built into any head unit. How do you have them hooked up? Did you set the gain level?

I don't know. Could it be my connection from the head unit to the amp. The amp had female XLR 3 pin inputs and my cd player was RCA's so I made something to link them. Maybe it could be that there is not a good connection.

I think all of my levels are set up correctly

There are instructions on page 9 of your owners manual illustrating a method for adapting an unbalanced signal (like from your HU) to the balanced inputs of the amplifier. Also, page 16 describes a quick and dirty level matching procedure.

Thanks. You wouldn't happen to have a link to the manual. My friend has the manual at his house
