I know nothing - help me out please

I didn't even know what to type in for this search. This is actually for one of my kids (in my youth group). He has a 600W amp and two Dual 10" 600W subs (with a peak of 1100W) . He just went to Car Toys and they did the full install. He has a decent pioneer head unit. The head unit will turn the sub on and it'll crank up to "10db". It also has controls for LPF and HPF which we figured out were Low Pass Filter and High PF. I googled that and figured out it determines how high of frequency or low of a frequency it'll allow. So, here's the question:

We want to give him the right balance of thunk with sound, is there a scientific way to adjust the amp bass/boost and crossover fq combined with the head unit controls of lpf, hpf, and bass level, OR do we just do it all by ear?

Thanks.

Ok. for the sub leave the High Pass Filter alone. Usually for balance I just sit in the front seat with a good cd in and have my friend adjust it on the amp in the trunk untill I think its good. BTW, dont crank too much through those DUAL subwoofers, they burn their coils easy.

whats the model numbers and all that on his sub and amp?

set his gains on his amp using a DMM, no bass bost. frequency crossover at 85-90. Have all the setting on the headunit at zero, but turn the subout controls to the max. then set the gain.

then for the headunit just change all that to what her prefers for it to sound like.

what's a DMM? He only has two controls on the amp - one dial for crossover and one for bass/boost - both have to be turned with a philips screw driver.

Also, when you say leave the hpf alone, what setting is that at? It can go 60, 80, and 120 HZ. Same with the LPF. Should they just be at 60?

a DMM is Digital Multi meter..... you can set the gain to a certain volts with it, by knowing how much power you want to send each sub. but by not knowing what subs & amp he has. i cant really help.

leave the bass boost alone. but use all the others such as LPF, HPF, & the level/gain

Hey, got another one. This friend was driving the other day and the sub just stopped working. What should I look for? He said all wires were plugged in. I'm thinking it could be a blown fuse - where would it be? Any other things I should check?

check the fuses on the amp & if there is a fuse for his power wire check that, check the ground & pwoer connections, push in on the subs if it makes a scratchy noise the subs are blown..

when you say "push in on the subs" do you mean on the back - on the magnet? Or on the rubbery part of the outside of the cone?

push in the direct certain of the cone...

well everything looked like it was plugged in still, but the sub was getting NO power - the amp had power (according to the light, but none was going to the sub). Since the guy just got this in June from Car Toys, he's gonna take it back and have them look at it.
