Ha yeah, well we might not always have the same philosophy but sensibility rules in this one!
Here's prices from one of the most common online dealers compared to my shop:
Stinger 8awg complete amp kit with RCA's and speaker wire: online-55$ Mine-50$
Dash kit - online-15$ Mine-15$
Harness - online-7$ Mine-10$
So it would cost less to buy locally instead of from California, and as Jeremy said you get the added benefit of service and advice too!
