I'm not looking to make any serious modifications to my audio. In my 2004 D2 I'm currently running a Kenwood Excelon KDC-X502 head unit with the stock LEAR HIPO amp and speakers, and for the most part it's fine. I see a lot of the Harman-Kardon Amplifiers on eBay, and not knowing much about it, I'm wondering if switching to that amp would provide more power and/or better sound.

Has anyone here switched out their LEAR HIPO Amplifier (XQK000010) for the Harman-Kardon Amplifier (XQK000100)? The plugs look the same. The mount is the same.

Just curious if any improvement was gained.
Thanks

 

I know whether it's a LEAR in my truck or not, but I noticed a distinct drop in quality when I switched it for the supposedly high-line HK amp from my old truck. No increase in power, but way more hiss and noise, so I switched back.

 

Interesting. I wonder if there is additional differences, such as speaker ohms.

The easiest way to tell the two amps apart is the way they look from the top.
