need help: for hook up the amplifie
 

my deck don't have a subwoofer outputs,only have a front/rear outputs,i want to hook up the amplifier,can i connect the rear outputs to the amplifier?thank you!

Yes but get a crossover to filter out the higher sounds. Make sure that nothing above about 800 hz gets to the sub.

that you meas i have to buy the crossover to filter out the higher sounds,or i can control form the amp?thank!

check the amp to see if there is a cross over feature on it. it might have a switch that says "hi/low/ful" or "hp/fp/lp" , put it on low pass and set the filter to around 80 hz or so and you will be good. If you dont have one on the amp then you will probably need to get one . Any car audio shop should have one available.

thank!!
