Help With Sub Sound Range...

[darita 10+ year member]

Yeah...I'm a newbee to audio, but something has been driving me crazy, but I was afraid to ask 'cause it's probably a stupid question, but here goes...

I have a Clarion Max685BT, 4 Polk 6.5" 651 speakers, a 300W 4ch Kicker amp and a temporary Fusion 300W 10" tube sub, in a Civic Sedan. I know the sub produces those very low sounds like from a bass guitar or drum that can vibrate the entire cab, but is that also where the "mid" bass sounds come from as well? By "mid" bass, I mean those slightly higher bass guitar and drum sounds that are so important to the music. Along with adding a subwoofer to my system, what else do I have to do to bring out the "mid" bass sounds? Please excuse my ignorance of proper terms.//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Most guitar and drums sounds come from the upper bass region, midbass, which isnt' usually handled by a sub. The lower part of the bass drums and the lower strings on an acoustic are all subwoofer range though. My car produces very realistic drums and guitars with no sub, for reference. Just missing the two things I mentioned. Anyway if your not getting those frequencies right now it's your speakers not your sub. Are your speakers mounted to a baffle, or just to the stock door baffle. Adding an MDF baffle can help alot. Also try switching the phase of your speakers, switch your pos/neg leads on one end of yoru amp, it may help. It may sound alot worse though too, if so just switch it back. The difference will be drastic and apparent, one way or another.

I had them installed, but as far as I know, they are just mounted to the stock door mount...whatever it cam with. What are MDF baffles? The rears are in the rear deck.

I forgot to mention that I have a stock sub in the rear deck. I like the range that I get from it, because I can hear the higher bass tones coming from it. When I use the Fusion sub alone, then all I seem to hear is the bottom end. Problem with the stock sub is distortion at slightly higher volumes. I do have the bass tone cranked up a little because I want to hear it and I don't listen to music very loud, but on some rap songs, that thing really distorts, so I end up having to turn it off and lose some bass tones. The Fusion is on with or without the stock sub.

MDF baffles are rings that you cut out of MDF to attach the speaker to. If you make some or buy some you can attach the front speakers to them and get better bass response. Does your amp on your sub have a switch called a low pass filter, it may be marked LPF. If so where is the knob pointing, which number?

Thanks for the response. There are no numbers, but it is set in the middle of it's range.
