orion 225r

finals in the amp are probably blown. Orion never used to use internal fusing on their amplifiers unless it was the 2250SX or 2100HCCA. The smaller ones relied on external line fuses which you had to supply. If the speaker leads touched, there was nothing to prevent the finals from getting fried as I found out with a 280GX once on an install. No internal thermal protection at all.
