I Had carfi install an oldschool us amp (usa-400) in my minivan, i called and received a quote, When i got there, the price was $10 higher. I was a lil disappointed,at first, but once i got in my van, the extra $10 was no big deal. They did a great job. At a glance looks totally stock. I am gonna go back and have my new crossover put in next week. Look forward to doing business with carfi again. You get what you pay for.
