Amplifier cutts out when I hit my tilt trim button on my boat

It;s not getting enough power. Seriously consider getting at least a 1 farad capacitor. It stores power for when the sub hits and recharges in between. I posted a tip explaining it in layman's terms if you look at my tips for more clarification. Please rate my assistance and leave a testimonial.

i have always heard that for ever 2000 watts you need at least 1 farad of capacitor. also once you hit more on the lines of 3000 or more you need a bigger alternator or battery and a capacitor is a must to keeping your amp running cooler and cleaner by keeping voltage drops to a minimum.

Check the wires going to the amp for any corrosion on the terminals and ground.

. Kind of like when someone squeezes a garden hose when your trying to use it. That would be the high volume, starving the amplifier. The capacitor stores power in it to power the amp at high volume. 2 farads would probably be bulletproof on a single amplifier system, but 1 farad should work well enough. Or seek help from an expert on exactly what size capacitor you should use. If you find yourself saying: My amp cuts out.

If this assisted in solving your problem, please take the time to rate it. Thank you.

1 cap, either .5, 1 or 1.5 farad will be fine. they make 5 10 and 20 farad that cost way more than u need to spend for 400 watts RMS. i like the rockford fosgates, you can get a low cost Tsunami, just make sure you follow the charging instructions.

Check the wires for a lose connection or corrosion. You may need a capacitor.

Basically, at low power the amplifier is not asking for a lot of power from the electrical system to power your sub woofer. For lack of a better term and probably the best way to explain it is. It uses up all the power in the wires leading to it at a high volume, and has to wait for more. Kind of like when someone squeezes a garden hose when your trying to use it.

If you're running the amp into a safe ohm load, it's likely that the amp is cutting out due to low voltage. You need to check the voltage with a multimeter connected directly across the terminals of the amp. If the voltage is dropping below ~10v, check the voltage across the main battery terminals. If the voltage is essentially the same at the amp and at the battery and it's dropping below ~10v, you need a larger alternator.

The 1 farad capacitor is something added to current hungry systems to help keep the supply voltage at the proper operating level.
If your amp does not work after putting one in your system, but it worked before you put it in, you most likely have it installed wrong.
The capacitor should be put in parallel with the main +B voltage of the amplifier. That means you would connect the positive side of the capacitor to the +B voltage supply of the amplifier and the negative side of the capacitor would go to the chassis ground.

If you have it connected in series, or inline with the +B voltage supply, the capacitor would be blocking the voltage to the amplifier.

Without more information on your problem that is the best answer I can give you.
If this does not help, please supply more information and I will be happy to help you further.

You should have blown a fuse. Check the main power fuse feeding the system (usually at the battery). If it appears to be good, you'll need a multimeter to check the voltage at the B+ and remote terminals of the amplifiers. Place the black meter lead on the ground terminal of the amp when testing. .

It sounds like you may have the load impedance too low. How many voice coils per woofer? How many ohms is each coil? If you have DVC woofers, are the coils for each woofer wired in series or parallel? Are the speakers wired in series or parallel. Let me know if you need me to clarify anything.
