Been seeing mention of bass blockers on various sites, and that they are used to prevent low frequencies from damaging your mids and tweeters. Having just installed new components, do you think its necessary for me to install bass blockers? Or does the passive crossover serve as a bass blocker? Please clarify

 

I don't know what a bass blocker is, but if your components have their crossovers installed correctly, I can't see a need for anything else.

 

bass blockers are a waste of money. Your Amp should have crossovers if its a good amp.. your head unit should have a eq/crossover if its a good headunit.. and your components should have crossovers if they are good components..

thats 3 different ways you can protect your components from frequencies that may damage them. I have my headunit crossed over at 100 hz and my component amp is 125 hz

 

they are resistors packaged in plastic with two wires coming out of them.. its a waste of money.. i had them in my Geo Prism back in 1998

 

cool, thanks for the clarification. I have fairly decent stuff installed, so just wanted to make sure I wasn't going to hurt anything in the long run. And as I thought, the passive crossover serves as a bass blocker in and of itself.

Last question, off my own topic: do our doors leak? Enough to where we should consider protecting the speakers? Another accessory I was looking at are baffles. What say you?

 

doors don't leak.. but dynomat behind them wouldn't hurt..

100 hz is a good starting point to put your crossovers.. but everyone is different.. and every component is different.. some components will do 50hz and some will start sounding like crap lower than 80hz..

you just have to play with it for a little till you find a happy medium.. then you might be driving.. a different song comes on.. and your components start clipping or a certain bass note you knew in the song doesn't come through.. and you have to either adjust your crossover lower or higher.. its tuned really to your music and your listening

personally i have my tweeters high.. some people don't like that.. its about what you really want

 

Damn Crutchfield trying to make an extra dime bass blockers and baffles. Thankfully I asked here first.

I have been crushing the internet the past 3 days trying to find a good "how To" guide on Tweaking Car Stereos and stuff. Honestly, the stuff confuses the crap out of me the deeper I get into it. I have an Alpine 9887 HU which has a ton of tunability, but I don't know where to start when it comes to 7 Band Parametric EQ's, Graphic EQ', Crossovers, what frequencies to set, how do I know if I am working with the tweeters on this menu vs. the mid-range... should I go active? Bi-amp? Crossover slope? Confusing!!! If anyone can point me to a comprehensive "Car Audio for Dummies" type guide, that would be great, otherwise I will take the cop out and just use the Alpine Imprint Kit again

 

If you have a set of 2 way components and a sub, and a passive front stage, theres only 2 crossover points to set. How low you want the components to go, and how high you want the sub to go. Assuming a simple set up of that nature, the rest is all up to you're listening preference. Active front stage gets more complex, depends on the frequency ranges of the midrange and tweeters, if you have a 3 way component setup and its active on top of that, theres even more to adjust via the crossover. When all is said and done, it's still comes back around to listening preference.

it sounds like trying to solve a polynomial calculus equation... I think I will just keep it simple and go with the Alpine Imprint... got the kit in the mail last night.
