2001 GS430 Mark Levinson Speaker Upgrade
I have a 2001 GS430 and I need to know a few things about the Mark Levinson
1) How many channels are on the ML amp, considering that the GS430 ML have a left, right, center, rear left, rear right, and subwoofer speakers?
2) What ohm impedance can the ML amp run?
3) What is the power rating of the ML amp?
3) What is the ohm on the stock speakers and woofers?
4) How are each speakers in the ML system crossed? Does the amp have a crossover or does each speaker have a cheap inline xover?
I need these questions answered because I want to upgrade all the speakers to Dynaudio without having to change out the amp. I understand that all the Dynaudio speakers are 4 ohm with the exception of of the MD330 and MD140, which are 8 ohm.
Any input will be greatly appreciated. Thanks!

Here are SOME of the answers.

The xover is more than likely a cheapo inline...unless they did some xover processing with the DSP. In either case, no real worries about the xover. The Dyns will run a much lower xover point than the stock ML system...it's a much better tweeter and very beefy. (If I could use that term for a tweeter.)
Unfortunately the ML site doesn't list any REAL specs. It's ALOT of marketing fluff. Glad you're trying out the Dyn swapout...something that I wanted to do. Think you will be QUITE pleased. Betting that the soundstage will get MUCH wider...and with much more detail.

mark levinson speakers are low watt and generraly 8 ohms on doors and 9 to 16 owhms on the subwoofer . i dont think there are any aftermarket speakers to match those numbers........................ mixing factory and aftermarket sound components is not advisable. aftermarket is all high watt low effiiency speakers in the hundreds of watts . factory speakers are low watt high efficeincy speakers. tuned to interior . the mark levinson amp cannot push an 4 ohm 300 watt aftermarket speakers. mark levinson speakers are 8 ohms 30 to 40 watt on the door speakers and 16 ohms and 80 watts on the subwoofers. this infomation can be obtained in your models service manual under the diagnosic section on testing the audio system. it gives the ohm rating that should be obtained during the test thereby revealing the unusual ohm rating.

the signal coming to the amp is just left and right channel . so you can tap the left and right channel wires and send this to an aftemarket amp and have aftermarket speakers and subwoofers connected to the aftermarket amp. this lets you keep your factory system but have an aftermarket amp and speakers if you want to rattle some windows when you come down the street. i know nothing about the best aftermarket system but i know you dont have to scrub your factory system to put an aftermarket amp to work in conjunction with the factory system. PERRYLA is the aftermarket expert on this forum.he wrote a book on converting lexus to aftermarket audio. i refer everyone to him for advice on aftermarket systems. i am only an expert on the factory lexus audio and navigation systems not aftermarket.

I want to go DVD, also. So, I will have to scrap the factory headunit. The problem is I want to keep the surround sound setup using the center channel, but is hard to find a 5.1 amp with enough power. Any suggestions?
