the audio system appropriate here 
what John and Bart said, your "custom audio system" belongs in the house where you can kick back, close your eyes, and immerse yourself in whatever noise suits ya, when you're driving [or in public shared spaces] pay attention to what's going on around you, blaring a stereo in your ride is as dangerous as texting while driving .... and why is a 'custom audio system' thread in a series specific forum anyway? should be elsewhere, like maybe the greasy spoon
