So the dealer delivers our new boat yesterday with the wrong amp. It came with the std Kicker 4 channel amp as opposed to the 5 channel Hifonics we had upgraded to when we added the XS650 tower speakers. The stereo sounds fine though I haven't kranked it up. The dealer has offered a $200.00 service credit if I keep the Kicker amp or I can have the units changed at my 20 hour service. What do you think my best option is? Any input would be helpful.

Thx.
