The ms-8 is commonly used by people with L7
The ms-8 is commonly used by people with L7 because the stock L7
amp is 9 channels and they have more speakers to power . The ms-8 comes in at 8 channels but only has built in head unit power on those channels.
The L7 can also be used by people with the ampless base system to overcome
the bad eq curve from the head unit in the base system without reprogramming the head unit to Hi Fi. Most that end up getting the ms-8
end up getting amps for at least the from doors and floors.
If you have a Hi Fi system or reprogram the Head Unit in the base system there is no need for the MS-8( or clean sweep) unless you like l7 surround or feel you need auto eq and a center channel.
