Bass Boost and LPF Crossovers

900 Views 6 Replies 5 Participants Last post by  alexlindeman
I've recently got a new amp, its an alpine MRP M500 and its 500W rms. Its powering a pair of 12" subs in sealed boxes.

Anyway, I've installed it, it looks nice and its loud but I'm still playing about with the settings and I've got a few questions.

Firstly, does anybody use the bass boost control? Whats the point in it? Surely if I wanna boost the bass I can just turn up the gain and/or turn up the subwoofer control on my headunit. Anyone know exactly what it does?

Secondly, what do you lots have your crossover frequencies set at? I'm trying to get a smooth transition between the subs and normal speakers across the frequency range. At the moment I've got the HPF crossover freq for the normal speakers set at 100Hz and the LPF crossover for the subs at about 150Hz. It sounds OK I think but is that too much overlap, too little, should I shift both crossovers up or down a bit? Any thoughts or opinions would be much appreciated.

depending on your speakers and subs...

i had my speaker amp set to all pass, and filtered it on my pioneer deck, at about 100hz

the subs, i had right at 100, filtered on the amp
