When my amp turns on it booms the subs very loud, is very annoying and wondering if there is a way to fix this, have had hooked up in different vehicles and different recievers so must be a setting on amp?

Re: Power up boom
The turn-on "boom" is caused by the amp getting the remote turn-on signal too soon after the head unit turns on. Most amps need a bit of a delay between them for the internal circuits to stabilize. Some amps have a built-in muting circuit that creates its own delay, but some do not. It looks like you have one of two options:
- If you need clarification, ask it in the comment box above.
- Better answers use proper spelling and grammar.
- Provide details, support with references or personal experience.

Is your gain all the way up? If it done this before, sounds like your over working the amp. Make sure your subs ohm load is capable with the amp load to. If they are 1 ohm and your amp is only 2 ohm stable, it would beat for a lil bit then go into protection mode to. Check your wires too.
your problem could be in the fact that you are trying to overdrive the amp. sony will not carry a 1 ohm stable load and if your speaker are 4 ohm speakers wired in series then you cant drive the bass your looking for. try using soundstream tarantula amp or new hifonics block mono class d amp with about 1000 watts rms. what kicker subs do you have? that will also make the difference in amp choice. im running tarantula on 4 polk momo 4 ohm 12's and has broke my back glass in my jeep twice one time was for a show. oh well let me know. happy boom boom. i'll be glad to help
the voltage regulator in the alternator or the capacitor is malfunctioning. get a multimeter on the battery when u start the car (before the capacitor) if it reads a large surge (something greater than 14 or 15 volts) then u may need a new amp, if not, then test it on the back end of capacitor to the chassie negative, see if u detect spike there.
