You mean now in your cobfiguration MS-8 is also the amplifier for speakers?? Obviously at moderate power.
This means you also coded the CCC for Hifi lo-level audio signal.

I installed the MS-8 after I did the CIC retrofit which puts out low level. The sound level the MS-8 puts out with the stock cheapy speakers is loud enough for me. I can get it loud enough to drown out noise from outside the car and still sound pretty clear.

I didn't know the MS-8 contain some amplifiers too. This means, in the upgrade process, it may be the first to install.

Here's the spec on the MS-8. I guess it's comparable to the OEM Logic 7 power.

JBL MS-8 Specs (power ratings are RMS)

CEA Power Output 18W x 8 channels @ 4 ohms
Maximum Output Power 30W x 8 channels @ 2 ohms
Frequency Response 20Hz - 20kHz
Signal to Noise Ratio (Line-in/Line out) >90dB
Signal to Noise Ratio (Line-in/Speaker out) >85dB
Maximum Input Voltage (Speaker-Level Input) 15V
Maximum Input Voltage (Line Input) 2.8V
Maximum Output Voltage (Line Output) 2.8V
Maximum Current Draw 16A
Stand-by Current Draw <0.01A


It has RCA low level outputs as well so that you can install more powerful amps such as a sub amp out of it.

So yeah..if you have the basic stereo or lower powered hi-fi, the MS-8 is a good upgrade which adds Logic 7 and more power at the same time. From then on you can step up to better quality speakers or additional amps, or both.

Thank you balbs.
This helped me much.

What version do you use?
- the two underseat midbass in parallel and you have a center speaker on the dashboard
- the two underseats separated and no center speaker?

balbs

Sort of like the first one. I don't have rear door speakers.
CH1 - Front Left
CH2 - Front Right
CH3 - RearD Left
CH4 - RearD Right
CH5 - Center
CH6 - Not used
CH7 - Sub Left
CH8 - Sub Right

Didn't know about putting the subs in parallel but it sounds okay right now.

So you didn't installed the rear door speakers.
