[QUOTE="tinmanchris217, post: 5988444, member: 610505"] The amp is another possibility. I have 4.5 ohm load on it, according to DMM. It's a 2 channel, class a/b with 60 amps of fusing. According to my math, 60 amps, means 770 watts of input power at 12.8V. 60% efficiency gives me a maximum of ~460w RMS available. This may be too optimistic though, since it is a VERY crappy amp. The fusing may be excessive, and the efficiency might not be that high. The voltage this causes across the bridged 2 channels should be 45 V. The 30 V that the "clipping" would happen at, means the amp is only producing 200w @ my 12.8 V battery power... which is thoroughly depressing. Thank you for the science lesson though, medicated thinking can be good for creative though.
