Alternator Question

So, I bought a 140 amp Delco Marine alternator to run my stereo and the place that I bought it from (DB Electrical) explained to me which wires went where and I proceeded to install it. Once I got it installed I tested it and it is not charging. Not wanting to ruin my weekend on the lake I hook my old 30 amp alternator back up. It ran my stereo fine with no problems at all. I have two batteries isolated by a dual battery relay. The stereo includes 4 Polk Momo Speakers and a Polk Momo sub powered by a Sony Amp (250 watts RMS) AND 2 Wetsounds Pro 80's powered by a Cadence TXA3004 which sends about 300 watts to each Pro 80. Now I have no clue how much amperage this setup draws but like I said it has been working fine with the stock alternator. DB Electrical has offered me a replacement alternator or a full refund and I am leaning towards the refund if I can get by with my old alternator. Like I said, I ran it all weekend and it had no problem keeping charged. Just wondering what you all thought about it. Thanks so much, Cody.
