I dont support the local shop in my area(car toys), as I have been in just to see what they have available, and over hearing the sales reps talking to the install guys trying to rip an older man off on some cheap a s s mtx subs installed 12s terminators for $600 with a 5/8 premade box.Yet, If I truely need anything, or have a question, and have tested them, and they are by far HONEST, and PERFESSIONAL, and FAIR, is a shop in Mesquite Tx.called Josephs Car Audio.They are knowledgable, and carry good gear, and have excellent installers,and seem to treat everyone with respect, and within all fairness.Yet, I usually do my own, and have since 89 installs, and buy /have what I need for my buildouts.But, if in the area, swing by and question them on something that not just anyone knows, but only a few, and i am certain that youll be satisfied, as I was, and am.Those guys know theyre STUFF:thumbupw:
