Default RE: capacitors and such

Really nice system setup up.

I had 4 12" MTX MXS1204 (800 watts max each)
2 MTX MXA8001 Amps (1600 watts max in 2 ohms)
4 2 farad power caps
and all the other stuff.

FatMat (to keep stuff from rattling) Do this first, I'll explain this on the very bottom of the page!!!

Thats 3200 watts I was hitting with.

I was running 0 gauge power wire and ground wire.

with a 220 amp altentor.

and yellow top otima battery.

I used Streetwires for everything that I could!!!

If I was you I would get:

4) 1 farad power caps, 2 per amp. Thats more than enough to keep from draining your battery and killing the altenator
Power caps
How to install multiple power caps

get ATLEAST 150 amp altentor. (This should be enough, since you should install 4 power caps.)

0 gauge power wire
4 gauge power AND ground wires

I install systems all the time for the last 5 years, I cant tell you how important that the 0 gauge power wire is, to get the power you need to power the amps, up to the distribution block then run 4 gauge.

-----------------
Get a distribution block that will distribute the 0 gauge wire to 4 gauge. Then run the 4 guage to the power caps, then to the amps.
distribution block

Ground the power caps at seperate places with 4 gauge wire. Same goes for the amps atleast 12 inches apart.
Ground Terminal

Then just hookup the speaker wires (I used 12 gauge power wire for the speaker wires.) PAY ATTENTION TO HOW YOU HOOK UP THE SUBS TO THE AMPS. If your amp can handle 2 ohms and your subs can handle 2 ohms, go that way. You will get the most power out of the amps and push the subs harder.
--------------

Once again here is where tons of people kill their systems fast.

Once you finish installing everything, double check all wiring, if all good, turn the bass all the way down, the gain all the way down on the amp(s)

turn your system on, LOW VOLUME, if your headunit displays number like 5, 10, 15, 20, turn the system up to 5.

DO NOT BLAST THE SUBS FOR ATLEAST 20 MINUTES, doing that will lower the life of both subs and amps.

After 5 minutes turn it up a little bit to 10, after 10 minutes goto 15, then 20 minutes 25.

The reason for this is that the cones and other componets is getting electricity for the first time, and they must get used to the electricity, like when you turn your car on in the morning on a cold day, you just don't rev it up to redline until about 20 minutes after you turn it on, see what I mean!!!???

After about 20 minutes turn the reciver to about 10, then turn the bass up on the amp about half way. Let the subs rumble, if they do.

Let them rumble for about 5 minutes, weather they rumble or not, just keep reading.

Put in a bass cd or something that has bass, and put it on a nice bass song or whatever.
You can download songs off my website (legally) (listed below) for songs that runs from 20Hz to 99Hz (very loud bass to good bass)
Download bass songs here!!!


Get near the amp and while it is playing the bass cd, turn the gain up SLOWLY, this will allow you to choose the best possible Hertz frequency to make the subs go BOOOM When the subs are booming the way you want them, don't touch the gain **** anymore.

If your amp(s) came with a remote bass controller use them to turn the bass from 0db to +18db or so.

Then after you setup your system the way you want it, check the wires once more, just incase the rattling has made a screw come lose, if it has, just tighten up the screw again, and make sure it tight.

After that drive around town with windows down, and system booming, go to Walmart parking lot (or mall parking lot) and see how many car alarms you can set off!!! (With mine I set off around, max, 20 at one time.
----------------------------------------
I was hitting around 140decibals,

OH you may want to look in getting about 1/2 inch windows, maybe plexi-glass!!! I blew out my hatch window in my eclipse with my system!!!!!

FatMat

Do this first, this will take awhile to do, find it cheap on EBay.

I took every thing out of my car, and you should do this also, the seats, door panels, dashboard, under the hood, carpet, headliner, EVERYTHING!!!

Place FatMat, everywhere, behind the license plates also, measure first then cut, Its fairly expensive stuff, don't forget to cut out holes for the screws and bolts. Car stereo installers charges 100's and 1000's of dollars to do this, so you may want to do it your self!!!

I spent around $300 for FatMat to do a complete car cover.

This link below is $99.99 + $29.99 shipping for 100 square foot. You may want to get 2 kits.

FatMat from EBay

---------------------------------

Hope this helps you out. It took me over an hour and a half to type this up!!!

If you need anymore help, you can email me at:

Later man, and GOOD LUCK!!!

By The Way, I want to see pictures after the install, I had to uninstall mine after I fried my distribution block for the spark plugs, so I have no pictures.

Email me and tell me what you think of this, I probably will forget about the site for several weeks!!!!

Thanks Man
