I have a cuspid USA 4 channel amp. Its crappy, but I got it for like $25 from some kid. Its 4 channels 400 watts per channel peak. I cant find RMS information, but it's probably pushing 100 watts per channel RMS, hopefully.
anyway, i'm powering two ultra linear 300 watt RMS single voice coil subs with that amp. However there is no crossover on the amp, so it sounds like crap.
basically I need to know the cheapest thing I can buy to cut out the highs...and how is it hooked up? RCA in and RCA outs? Does it need to be powered? if so what guage wire.
for the record, this is not for me. I have a decent system. I'm doing this for a friend who has no money, and doesnt rly care about SQ. she just needs a bit of bass. so really, cheapest easiest thing please.
I need to install it soon so PLEASE HELP.
I appreciate it. I just have no experience with crossovers. |

cheapest solution is using a choke or coil on each speaker.
that's a first order low pass filter.
should run ya about $20.
any decent car audio shop should stock them. just know the power handling you need, and the impedance of the circuit to figure out the rating for the choke. |

If you can shop ebay or pawn shops for an active crossover or amp with a LPF in it. You might find one for $20 if you look hard enough. You can buy cheaper brand new ones for around double that like pyramid/boss/etc. They would work for that purpose. |
