[hotwheelsgt]

i have a 2ch 300w amp i dont think it has a crossover and i was wondering if it would sound good with 2 12s or am i shit out of luck because the amp does not have a crossover. or how could i make it work better.
amp older rockwood
subs pioneer 450w max

I recommend finding an active crossover to put in line if you want to keep that equipment, but in all honesty, I'd drop the rockwood amp, invest 150 - 300 in a decent amp with a built in crossover, read up on here, you can find good names in amplifiers.

i think a passive crossover is less likely to induce noise than an active one, but i also agree with DJ...lose that amp and spend a few to push those subs right

alright il try to get new amp. can i use that amp to power my 2 ways and will it give them good sound

every speaker cannot play every speaker clearly at all levels. full range speakers come close but there's usually a trade-off. if your amp doesn't have any built-in filters or processors, your going to have to buy an external one (equalizer, crossover, processor, etc...) so that the right freqs. are routed to the right speakers.

ok help me a little wut is a passive crossover and wut is a active i think an active goes in the line passive is almost the same but more complex am i right?i found a radio shack crossover i think it an active cross over it has an + - on the in and a com for - and it says woofer on one side with diffrent places to pute a wire and the other side says tweater with somemore places for wires wut should i try to hook my sub to i know i have to hook it to woofer side but there is diffrent places they are 2k 2.5 4k wich one is best

passive crossovers are the kind you see inside your speaker cabinet or connected to your speaker, they usually work with high level (amplified) signals. Active crossovers are the opposite, they usually work with line level signals (before amplification). I suggested passive instead of active, because, to me, external acvtive networks are just another entry point to induce noise, while passive on the other hand helps to filter some noise. If you induce noise at the signal level, it's going to be amplified by your amps and then get routed to your speakers.

ok so i have a passive crossover. this is no high budget system as you can tel im just trying to make dowith wut i got free sub free amp free crossover free head unit. so i was just trying to use wut i have . so should i use 2k 2.5 or 4k on the crossover thanks

those numbers represent the upper freq. you may want your mids to cut off at, or they could be the lower freq. that you want your tweets to play. remember there is a difference between woofers and subwoofers. i don't recommend any of those settings for your subs, as a matter of fact subs don't usually play that high. that crossover sounds like it was designed for a woofer, tweeter combination, like in a componet system. so basically check the freq. response of your woofers and tweets and connect them at a freq. they both can play. if there is a range of freq. they both can play, choose the one that sounds like it has the smoothest transition from highs to mids for your particular woofer/tweet combo.
