Amp isn't producing much bass...

When I first turn my head unit on, the amp makes the sub hit hard for a second, then it like dies out. What is wrong with it?

I'd check voltage at the amp first....

bad rca's?

Thank you. Would have the RCAs and power wire cross, cause them not to sounds as loud?

I was just wondering how I would check the voltage on the amp. Thank you.

Really to clear things up. Amps dont produce bass. Thats what subwoofers are for.

That won't hurt anything, check the voltage at the amp by taking a multimeter and setting it to DC volts (a max range of 20 would be ideal) and putting the positive and negative leads on the power and ground terminals of the amp and see what it says. Do this with the system playing turned up. Ideally you want around 14 volts, if you're dropping down around 12 I'd consider some electrical upgrades. Check this at the amp and at the battery terminals, if the voltage at the amp is significantly lower than at the battery your wire is too small or you're connections are weak somewhere and that problem needs to be addressed ASAP as well.

That'd be the first thing to check, along with all your connections at the amp and sub; post here what numbers you get on those tests and we can help you figure things out.
