I installed a Boston Acoustics GTA-504 and since install I have not been able to charge the battery during long drive with the music cranked up. I really thought the 55AMP alternator would have been fine for the small amp.
I am running 6.5" separates on 2 channels and bridged the other 2 channels to mono for the sub. All speakers are 4 ohm. There are two 25A fuses on the amp and I added a single 60A in-line at the battery for the power to the amp. No fuses have ever blown - but I wondered if the alternator is actually cranking out 55 Amps. If I don't drive with the music on it works and charges the battery fine. I think I might just install a bus alternator (75Amps) unless others think it is a mistake. Link to install manual: http://www.bostonacoustics.com/PDFs/manual..._2_4_Ch_Man.pdf Quick Specs:  |
