Looking to get some help installing an amp and a sub in my 2002 silverado, the sub is already in a box, and will be sitting on the back seat in the middle. here's some pictures.









Got it from my girlfriend as a gift, and i'm looking to install it myself. Or if worst comes to worst, i guess i'll have to pay for the installation.

I have a stock head unit, and stock speakers, there is no aftermarket anything for audio in my truck.

I'm also looking to get a little help on how to wire my speakers into my head unit also.




There's the box i made from scrap wood, and i have a couple 6x9's from my brothers car that i made it for.

I've heard you can set off the air bag by screwing around with the wiring on the head unit, is this true?

If you don't have a Bose stereo then this is not that big a job. A store is going to charge you probably about a hundred plus the parts you need to buy anyway to install that amp. It's probably worth it.

If you can not find bassblockers at your local audio shop you can use 200 Ohm resistors from radio shack. you only need to install them on the + wire on each stock speaker. This will allow you to crank it up with less distortion from the factory speakers by removing the lower frequencies which they can not handle at extreme volumes.

I'd love to know how.....a 200microfarad capacitor inline on the + speaker wire will give you a -6db/octave passive LP filter starting at 400hz but I've never heard a resistor would do the same thing........

I tried to add this above but I type so slow I ran out of time.....

To the OP: your amp has speaker level inputs.....splice into your rear speaker wires and add a pair of wires from each speaker and hook those to the corresponding input on your amp. By setting the LP filter on the amp and adjusting the gain correctly you can drive the sub that way no problems.

Also, a generic band-pass box missing it's ports is going to sound like *** no matter what speaker you put in it. If you cannot get another enclosure for it you would be better off removing the plexiglass plate from the front and sealing the 2 holes on the top with a piece of wood screwed down on the box. It may not seal perfectly but it will still sound better. I'm not sure how you plan on installing the box for the 6X9s, if you are using them for rear fill you should have them in separate boxes you can put at either end of the seat and point them forward or maybe up at the ceiling.......

as the big red guy said .... do not use resistors in line they do not do what 300C SRT8 thinks they do. A bass blocker is a bass blocker, a resistor is a resistor, they do entirely different things.

HMMMM last time (and the only time I heard anyone talk about 200 ohm resistors) was on http://www.canadiancaraudio.com/online/install-related/174756-where-buy-bass-blockers.html... and evidently that is where 300C picked up this lame idea

A bass blocker will be a NON-polarized capacitor

I sit corrected....forgot to mention the type of cap.....

It's a good thing really, you can't hook them up backwards.....

I stand corrected
As I was replying the original post I remembered I bought mine at radio shack and still had them in my garage so I went to see what they were they have 200 written on the box so I assumed that the previous poster http://www.canadiancaraudio.com/online/install-related/174756-where-buy-bass-blockers.html was correct as I am not an electrical engineer such as yourself. I just went and looked again and they are indeed a 200 microfarad 100v non-polarized capacitor box of 12 $9.95 in 1999 its been 10 years since I bought them and my memory can be a little fuzzy sometimes I had the same issue back then just wanted to improve the sound with very little cash bass blockers were $10.00pr and I bought the box of 12 for the same price. bottom line is bassblockers ( 200 microfarad 100v non-polarized capacitors) work very well when adding subwoofers only to a factory system. They are relativly cheap and simple to install I used 4 back then (1999)in an 83 celica and later used 4 more four years later (2004) in my 2002 durango (which sounded awsome by the way) and still have 4 left. I now have two sets of Focals in my doors and a 10w7 in the trunk both on JL Audio amps 300/4 & 500/1 so bass blockers are now a thing of the past for me.
