Shoot.... I have a spare Alpine amp for the stock system (for a 2003) just lying around. But if it won't work on the earlier cars it's probably not worth a gamble.

 

Problem is not in my cars listed in signature.

Problem is in 1998 Convertible and amplifier I tried was from 2000 XKR Coupe. And 2000 XKR has Harman Kardon too. But Convertible and Coupe amplifiers have different part numbers and clear texts "Coupe Amplifier" and "Convertible Amplifier".

I have already changed the radio (head unit) from 2000 XKR. So connectors behind are well fitted. And there is no switch behind head unit.

So I'm still seeking any tips how to get "S.W Level" back and also the tips for distorted bass sound are greatly welcome.

I did not even change the amp in mine and the last owner said nothing had been done to the stereo. I have no S.W. control in mode and the bass has to be at -7 and treble at +7 with the fader toward the back or I get temendous distortion. Muffled sounds heard up front and back speakers sound great. I have 1998 XJ8L with Kardon Harman sound. The distortion now has blown the sub. I was told to pull the head unit and flip a switch on the back back and forth several times to get the head unit to realize it is in a premium sound car. There is no switch..... there are tiny rotary switches on the one side on a circuit board but nothing on the back.
What happens when you press the AM+eject+9? Is that a way too get to a menu? I have the stereo out now and the trim all replaced to slide it back in but I don't want to do this just to try the AM+eject+9 handshake.
I also don't want to turn the switches in the side of the head unit without knowing which one and what they do. Someone please help. My headunit is definitely in the wrong mode.

 

BurgXK8: Sorry to bother you, but you don't by chance still have that Alpine power amp lying around do you? Mine just fried on my 2002 XK8 coupe and it sure is quiet in that car now! Thank you!

 

I believe I have my old one (I upgraded the sound system)... if BurgXK8 doesn't have his then let me know!

 

Thank you so much, Blindside! I intend to pull the dead amp this afternoon, to confirm the part #, but should be the same Alpine system as your 2001. Talk soon!

 

Part # on my amp is LNF4170AA. The amp itself certainly appears to be the issue, because with it removed the 30A fuse has stopped blowing.

 

Just saw this - LMK if you still don't have yours and I'll gladly part with mine for free, plus shipping.
I'll be out of town for a couple of weeks though.

 

That is incredibly generous of you, BurgXK8! I'd love to take you up on that (assuming that yours is the same part # LNF4170AA). Just let me know and I'll PayPal you the $ for shipping immediately. Really looking forward to having music in my XK again! Cheers!

 

NP; send me a PM with your details.
Will need some time though, like I said.
Hope it works for you.

 

I had same thing happen, amplifier connection was loose. Easy fix.

 

Thank you, bcampie, but my amp is definitely dead (I wish it were just a connection!)

 

Was this wire connection in the trunk or behind the head unit?

 

Qualcuno ha la fotografia di dove e' posizionato l'amplificatore nel bagagliaio? grazie

 

"Does anyone have a photograph of where the amplifier is located in the trunk? thanks"

Check this post of Marsden's - second picture:

The amp may be different depending on the age of of your car, but, if you have one, it is in the same place on the RHS behind the carpet trim.

 

I'm having the same problem with my Premium Sound System with my 98 XK8. I've read through the threads and appreciate all the information provided. I started with checking the fuse that should be located in the trunk, however, the space where the fuse should be is empty and doesn't have any electrical connector's for the fuse to plug into. In other words its no a functioning fuse. It's as though I don't have the premium sound system. Does this sound normal to anybody? Also, If I could get information on where the remote signal wire from the radio to the amplifier is located I would greatly appreciate it. Thank you
