Lets see those systems!

Those fiberglass boxes look really nice. Are they hard to build?

Chad

Not hard with the right tools ... but they are very time consuming

-Couple more pics

Hey Toxic, that fiberglass box looks nice!!! I made one for a spare tire well, but I used felt instead of grill cloth so it was a PITA to get smooth (I gave up)

LOL, I've used felt once upon a time. I have also found that t-shirts work great.

nice set ups levi and toxic... I found out very young that ohms and rms are key to stereos....

Anyone want to help me out with ohms? I really don't understand much about them and I would like to know whats up with them lol. But rally, that van is sweet! Haha I have always imagined what it would be like to have an astro van to fill with car audio. Looks like you have always been a JL nut too.

I'll get some pics up tomorrow. It ain't pretty but it's loud. Specs..1989 Caravan Turbo....52K RMS on 2-18s. 8 big 8 volts 120 2 volts configured for 16 volts. Enclosure.....roughly 26 cubes.180 foot square tube steel cage shell. 11 ply baltic birch and 1in MDF. simple, strong, vented common chamber. 162 db certified legal on the TL.

MKF soundoff......LOL I can hear the whining now.....(in a sniveling voice)"his doesn't even play music"......

There is NO such thing as too loud.

ohms are resistance to power... series wiring adds the ohms together ad paraell wiring drops the ohms match your rms sub rating to the ohms then match to the amp...

Getting the most bang for the buck relies heavily on the "ohm load"

Whew thats alot to catch on to...So should I aim for a low ohm load or high? And matching the amp to the ohms? I am a bit confused I guess. Still learning.

Impedence is a crazy thing....all speakers are rated at rest. When they move it changes and the enclosure directly changes this...the type of enclosure and the size of enclosure..

Simple terms.....you can run lower impedence in a sealed box cause the rise (actual imp. during play) is much higher than a ported box. You may be able to run .25 ohm in sealed enclosure before the amp protects where you may only be able to run down to .5 in a ported box. You can calculate all this stuff with a DMM and clamp. I tried to figure out how to manipulate this 2 summers ago and almost drove myself insane.
