Need help with new stereo system!

[OliverM5]

Just installed 2 amps with 1 15" sub, and 6 6x9's. I also installed a new pair of walmart marine batteries that were dead when I bought them (but I charged it up)....when the volume is turned up and the bass hits (motor is off and stereo running off 1 battery), the system cuts out momentarily - I suspect this is due to the power draw of the amp when bass hits....is this normal?
I have not tested it while motor is running yet - the alternator running may solve the issue, but I want to be able to play it while motor is off...could it be the batteries are bad? Should the system be able to run off one good battery when motor is off and volume is cranked up?

I have been thru similar situations with cheap batteries. I currently have 2 Odessey 2150's designated for my stereo & one smaller Odessey as an emergency starting battery. I can run my 500w amps hard over a 3 day weekend with no recharging. May cost you more at the start but its worth it to not have to mess with it.

What size power cable are you running?

[jbone]

Sounds like a power problem.
Check the gauge of wire/cables used, esp ground.

[OliverM5]

Running 4 gauge...so you guys think its my batts?

[jbone]

You could try some bass capacitors.

You say the "system cuts off". Please describe exactly what happens, not so vague. The sub amp shuts off? The head units shuts off?
The whole system kinda loses "volume" at the same time the bass notes hit....my power cable is 4 gauge and ground goes directly to the battery (8 gauge).....

Just messin...
Because caps add resistance and you only have 12v to work with(motor off), a cap in a boat isn't that great an idea...
I agree with ShockwaveBOB...

Oh...
I guess that's why I don't have them.
But, I have 2 batts dedicated to stereo. I never run out of juice. :p

1 15" and 6 6X9 on two amps? Are you running a 4 channel for the 6x9's and a 2 channel for the sub? If so check the ohm load on the four channel as well as the 2 channel. You might be overloading the amp or amps. Who makes the amps if I might ask?

wow 2 post and thinking the same thing i was thinking ;)
