Here's my setup:
-Crappy JVC head unit
-Pioneer 4x6's and 6x9's
-Kenwood Amp
I have it filtered so only the highs go to the front 4x6's. I have the rear 6x9's running full range. The system sounds awesome except for the fact that when loud bass hits in the rear, there is so much plastic and crap that it rattles like none other. That and the fact that these speakers aren't really made for a lot of bass. So I'm adding a sub and another amp. My question is, is there a way I can have a lot of bass goin to the sub, but not the speakers? I believe on the amp I have now, it just has a high filter, low filter, and full range, but I'm not totally sure. I don't wanna cut out all the bass out of the back cuz that would sound like crap. What do you guys think? Any suggestions would be greatly appreciated. Thanks.

Run the subs low passed from the amp at 50 hz. If your running from the headunit itself to the rest of the speakers, then get a pair of bass blockers for the front and back if your speakers are that bad. I run my back 6x9's at 50hz, and my 4x6s at 200 hz, both high passed. Get some tweeters to, and mount them inside your heater vent so they face you... neat huh!

Noooooooo, not bass blockers!!!!! Those thing suck they reduce sound quaility and reduce current.(proven fact so don't flame here Thanks) Are you running a sub preout on your deck? If not don't run your bass past 0 or +1 then adjust your amp accordingly.

 

Turning up the gain on an amp is what causes more distortion at higher volume levels. Bass blockers are good if you have a small system with quality speakers. Personally I don't like using them but they are the cheapest way to keep distortion from effecting mids and highs at higher volume levels.

The first thing you need to do is stop some of the problem at the source! Try to reduce the rattles in the plastic etc. I've not had that much of a problem myself, so make sure that all the plastic is aligned and screwed down properly. What CODY BEHNKE said is correct, you can fix your problem by adjusting your deck Bass and Treble levels, so that when you turn up the volume to where you normally listen, without the subwoofer on, the 6x9s are not distorting. Try putting a little more Treble into it and use the fader so that you don't have problems. Now is the time to sewt up the sub. The quality of the amp and speaker, will dictate how much gain you can adjust. If you have a bass booster on the amp, turn that on, or turn it to about 3/4. The size of the speaker and the enclosure will decide where to set the band pass filter. A 10in would be better suited to 80hz, unless in 4th order band pass, and going down the spectrum from there. It is true that the mopre gain you set on the amp the more distortion you have, but that all depends on the THD of the amp in question... they are all different. Power is not everything, it is exactly like building a good smallblock, everything is tuned to everything else. I am assuming the JVC has pre-amps, and if it has sub RCAs then all the better. The best solution is to get an Equalizer. They sort out a lot of problems and you cantune to the music you like to get the best sound etc. For those of you who don't believe in EQs, and the salesman guy etc. If we don't really need and EQ, then why does every deck now made, have a 2 band Equalizer built in? (treble/bass) I rest my case, and good luck...
