Crown amps are considered by many to be the industry standard, providing flawless performance when used with high quality mains/subs. They are also known to last for years with proper setup and use. The XTi 6002 is a great buy, providing a clean and powerful sound with a low power rating. It is also compatible with Yamaha SRX15 speakers, although some caution should be taken when using it with lights or circuit breakers.
