Be installed tomorrow pushing a Memphis 10 S series shallow mount underneath the driverside rear seat inside a custom enclosure! I'm keep'n everything else stock @ the moment but the idea to install that JL replacement up front is an idea... The D Class is a bit dirty but 4 ohms, 300 watts... I'll keep the bass boost down all the way & keep the gain bout half to keep it tight & punchy! I'll let yall know how it sounds tomorrow night!
