I have a Blaupunkt component set which is basically 5.25" speakers with 1" tweeters, and passive crossover, in my front doors. The frequency range 70 to 22k hz. These are running without any additional amplification off of my OEM ford HU. I'm also running a 12" subwoofer in the trunk with a 400 watt Kicker amp in the trunk. Since I'll get enough bass with my sub. I'm considering adding 300 hz bass blockers to the front door 5.25s. Where should I install the bass blockers? Right before the 5.25 speakers or before the crossovers?

if you block everything below 300hz from making it to your comps you are going to be missing frequencies, which is never good.

I doubt your sub is playing 300hz and below, and if it did it would sound horrible. Best cutoff is 80hz and up for frontstage and 80hz and below for substage.

Some people go down to 60 but a 60hz tone sounds bad on a comp speak to me unless your door is deadened really nicely.

:word: You're going to be missing a LOT of your music if you cross them @ 300hz.

If you can, get something around 80-100hz

As for the location ... Either will work fine

Try 100hz; that way even if your sub is crossed at 80, you'll have sufficient overlap.

you may get alot of bass but not midbass. If you want bass blockers try it at 100hz or 80hz, not 300hz. My suggestion is to get an aftermarket HU that has a HPF to help you. This will do a better job and be more customizable than a bass blocker. Also amp your components!

This is all helpful information. I'm a newbie when it comes to car audio. Thanks to all!
