From Mazda to Saab to soon to be VW. This place does audio systems right. Rick installed 2 systems on my old Saab and Mazda. I look forward to having them do my VW as well! Give Megan Watt a go and you won't be disappointed!

Rick is extremely nice and extremely knowledgeable, and Lauren will have you on your way in no time. A well oiled machine for sure, thanks for making my experience quick and painless to say the least! Can’t recommend highly enough!

The didn't have what i wanted in stock. Or any similar items (12" sub). However the staff was friendly and knowledgeable, offering like for like replacement advice for free. Even putting up with me coming in 5 minutes before close. They were not rude and still stopped working on an install offered the advice for free
