sterio help

we took the boat out for the sterios first trip it looks really good and sounded good but then..., first let me explane the problem and wut is happening and wut eqepment we have. allright when we bought our boat we ahd a sterio installed 2 12's, 4 6 1/2's, a 1000 watt amp, and a panosonic deck. then a coulple of weekes ago we decided we were finnaly goin to have the boat offically pimped,oo yea when we had the sterio installedthe first time we also had another batterie installed and it is isolated,so we took the boat to the sterio shop and had them make us a coustom box that held 8 6x9's. 2 down and the other 6 out he back, we also had another 1000 watt arc audio amp, a arc audio digital eq, and had it all profesonalie wierder. so we get the boat home friday nite play with it all saturday no problems. then we take it out sunday and it workes grate 4 about 2 and a half hours the boat is running most of the time, btw it sounds awesom, then after about 2 or so hours the whole sterio is running and the towere starts to kick on and off, and then finnaly the tower just stops working. i went out there a couple of mins ago and every thing woked fine untill i started to turn it up then the tower kicked off agin, the boat spekers and the subs work fine, so i dont think it is the eq, the tower is run off the front channel of the deck, and the boat off the back and sub cannel, the arc audio 1000 watt amp only runs the tower and i cheked all the wiers, so is there any thing i can to befor we take the long drive back to the sterio shop, please help chris

sry bout the double post, chris

sounds like the battery is dieing or the amp is overheating, most likely a combination of both, did you install a larger alternator...if not do you realize how much current 2- 1000 watt amps draw??

oh yea , you said you have 8 6X9's off the one amp how are they wired??

8 6x9s are off 1 1000 watt amp and 4 6 1/2s in side along with the two subs are powered from the other amp, we asked the guys who did the sterio if we needed a bigger alternator and they said we will be fine, we have the two batteries they are both optimas and we cheked if they were dead they both had plenty of power, the sterio shop sent us a new amp, ang we riged up a colling system, were gonna se iff that works, also do u think 4 gauge is enough for the two amps, also about the alternator do you think we should get a bigger 1 because we have the stock alternator on a merc mx 6.2 black scorpian in a sanger v230. thax 4 the help
