Gday from sunny australia, Im running 2 i5 inch pioneers of a sound storm amp and pionner 6.5" splits [front] and 6.9 in the back, they are running off an boss ba2900, my question is the spits have a passive crossover between the tweet and cables and the boss amp has cross over switches on it they are LFR, HFC and FULL and a dial for with HFC under it I want to get as much high and mid sound out of them as i can because at the moment there is a little to much bass from the subs,
So what is the best to set my cross overs at??

Gday Mate,
Each vehicle has its own sound characteristics. But some general starting points to consider are as followed:
Sub setting: Set sub amp filter to LPF (low pass) between 80 - 100 Hz.
Front Splits: Use full range settings here as the crossover will do the rest for you. If you find there is too much MB up front, can use the HPF (high pass) filter on front channels. Set at 60 - 80 Hz.
Rear 6x9: If these are 2-3 way full range, set HPF on these channels to 60-80 Hz.
If your system is still bass heavy, adjust sub amp gain to bring bass down to suit your tastes.
Good luck,
Swez

if you have too much bass do not be afraid to turn the gain down ont he sub amp. It is good on the amp, and yer ears....

cheers for that it sounds right,
Another quick question I have 2 batterys in my car the first a small one to run the car and all acc and the deck and the second to run the 2 amps, the amps are 240w rms and 440w rms how many amps do you think both amps would draw out as I am puttind in a new altinator and a relay iscilator and am not sure how many amps im going to need

If both amps are Class A/B type Mosfets, can anticipate close to 100A max current draw here. Nominal current draw at average listening levels will be under 70A. The 2nd battery will consume an additional 10A of power to keep it topped off under loaded conditions.
If you plan to upgrade the electricals, figure a 150A ALT will do the job with some reserve power to spare. All depends on your listening habits.
