I got a 4 channel amplifier and hooked everything up today. On channel 1 and 2 I have 2 9x6" speakers and on channel 3 and 4 I have some small subs. I hooked the amplifier to the radio with rca cables. The only problem was after it was all set up, I was not able to configure the amp to send much bass to the subs, what should I do at this point? Do I need low pass filters on the sub connections? The amplifier is a Boss Rip 796.

 

boss amps are a joke man. If it doenst have a built in xover you are somewhat screwed

 

Dude, I ain't asking if boss amps are good or not, frankly I don't car bc this amp was very cheap and I did not have much money to put on it. And yes, it does have an x-over but it still seems to be letting pass too many highs.

 

Chances are the x-over only has a 12dB/octave slope. This is NOT a brick wall filter that cuts everything off at a certain point. The highs will still be audible but at a lower level.

 

This is what my instruction booklet says about blocking the high's: "use a wire coil inductor to block high frequencies from the subfoower". Do you know what they are talking about?

 

A coil (or choke) connected in series with a subwoofer is only a 6dB/octave filter. Also called a 1st order passive low pass filter. This is even shallower than a 12dB/octave slope. Crossing over a subwoofer passively is not a very good way to go. An active x-over is the way to go when crossing over a sub.

 

defensive eh

 

yep

 

Tnx for the info, I'll have a look at that. Btw I see you have boston acoustics for speakers, how do they sound in a car? I went a while back to hear some home theater boston acoustics and thought they sounded amazing!

 

They sound great! WAY better than the POS Infinity speakers they replaced.

 

I'm running MB Quarts in my front doors with one 10 inch Sub. If I was you try amplifing the front doors instead of the 6x9's which I'm guessing are sitting on the back hatch area or you cut them into the sides. When you go to a concert or movie the sound comes from the front not the back. Trust me it is a much better way to go even if the front door speakers are factory oem.
