The amplifier on my 2004 Pacific had been malfunctioning for quite a while. I finally took it to Mobile Werks, and on the way there, it came on! Well, they couldn't find a thing wrong with it, and spent the day trying to find the problem. I was a little upset, as I figured I would have to pay a charge, and it still wasn't fixed. No charge! Ahab the owner couldn't have been nicer, and told me to bring it back when it went off again. Sure enough, it went off again, and he went to a great deal of trouble to get me a used amp, at a reasonable price. He went all the way to Brooklyn for it, and had it installed & ready for me at lunch time. He even fixed some badly installed wiring to my navigation system, and did not charge me for that. I cannot recommend them more highly. They are honest, helpful, and I will not hesitate to go back again.
