HEy there...
Can anyone please help me with suggesting how to set the amp gains....?they can be to the max .....should i wait for speakers to get distoreted.../?lols .. some idiot car mechanic told me this.????please tell me whats the best way to set the gains of the amp and please explaing a bit about the crossovers....?what are these for.....i know it is down to personal preference in the end but i would really appreciated if i can get some guidelines on this...
thanks

Im no expert..but from what i remember doing...set all your EQ controls on your HU to 0...turn your amplifier gain and DB boost to 0...turn up the volume on your HU to a high lvl (higher than you would normally play) then slowly start raising the gain on your Amplifier till you start to hear a little distortion, then turn it back a tad...this is how my buddy told me to do it..if im in the wrong im sorry please correct me. Im sure Swez, chronos, ttocs will be around shortly to explain the whole process. (PS this was to set the gains for my Subwoofer amplifier)

There are different ways to do it but with the options on decks today some may vary from others. Most newer decks have built in eq on these models you want to use the custom settings putting low = 0 and mid = 0 (treble is fine to change). Make sure you don't use any bass boost settings on the deck like loudness.
On the amplifier the depending again on which model has some features to make the amp be able to power any type of sub or speaker Mono amplifiers are for sub woofers only there are also the class T amplifiers which are for sub woofers that are much more efficient than class A/B.
Settings on you're amp
Cross over - Generally with this there are 3 different features LP Filter AP?(hm) HP which stands for Low pass, full range, High Pass. Than you will have some nobs to tune you're frequency. Of course when you're running subs you want most of the low frequencies and not so many of the higher mid because it can damage you're subs It's really easy to tell when it's happening also. Now for setting it is more on you're preference and what sounds bests in you're setup either (lowest) 50, 70, 90, 120 it's okay to test out what all of them sound like but please note at a low volume inscase the sub gets any high frequence.
Now that you got all that figured out go ahead and get you're small flathead out and turn the gain nob with the volume on low. You will notice the subs changing in volume when you turn the knob. The best way to know how much gain you can put is to know the RMS ratings of you're sub woofers and the RMS ratings of you're amplifier @ 12.5v - 13.5v. Sense you didn't say the brands and model numbers I can't answer that question. So check out the specs of both the subs and the amplifier and if they are close you can turn it up all the way accordingly.
By this time you should have things pretty good and it's time to turn it up a bit more to test it all out at a higher volume. The best way to test to make sure you're subs aren't distorting is to do this with you're trunk open and stand next to them to hear for any distortion. Also check for any leaks around the subs or the box. By doing this you can know you're limit to how much you can turn it up so you don't have to worry about blown subs!
If you have any more questions let me know

THE amp is apline Mrv 450 and the sub is pioneer 12" 305 C SUb....cant really figure out what specs you need...?i guess you can figure that out since i have given you the models...thanks

Here's a step by step FAQ on gain setting for amps. It's good for subsw, but same idea for full range too.
