I need some sub advice

Im looking for a inexpensive system for my car, nothing fancy, Im only 16 so I dont have much money, but I want some boom.  My car is a 1991 2 door Chevy Cavalier.  Im trying to decide what sub to get.  Im trying to decide betwen these two.

AudioBahn Dual 12" Tuned Bandpass System 800 watts RMS

I like this becasue the subs are already in a box, so I dont need to bother with building or buying one, plus it has the neons, which are cool.

The other sub im considering is a Audiobahn 15" Alum Sub 1100 watts RMS.

The 12"s are 139.99, the 15" is 159.99. Both from cardiscountstereos.com.

I will be buying a pyramid 1000 watt 2 channel amp to run them.

Which of these is the best buy? Will the 15" pump better than the 12".

I dont really know that much about car audio, and dont know anyone that does. I dont have alot of money to spend on a professional install. Any advice would be greatly appreciated.

You can get much better equipment for your money.  Nix the Audiobahn and Pyramid.  There is much out there besides what is at your neighborhood store.  For the sub, you can order this http://www.partsexpress.com/pe/pshowdetl.cfm?&DID=7&Partnumber=260-581 and the box is calculated and built for you.  It's audiophile sound for a great price.  You don't need two, just use one sub.

For the amp, I have had really good experience with this amp in the 4 channel version, but otherwise identical  http://www.thezeb.com/detail.aspx?ID=3511  You'll get bang for your buck with this, and it looks good too.  You can bridge the sub to this amp.

Your keeping the car's radio head unit?  If so, you'll need a line output converter to run a signal to the amp.  This is a good one  http://www.autosoundgear.com/tek9.asp?pg=products&specific=jnqrdnr8

Set this up in your car and then go compare it to somebody's Audiobahns running off a Pyramid.

Dyon is right....stay far away from the profile amps...you might as well buy roadgear. I have installed many of them for customers who bring them in and they just don't put out the power they should. i used to have a 91 cav and i went with the 15, two 12's and two 10's. just my suggestion now....but if i were you i would down the sub size and go for a pair of decent 10's ( the audiobahns are pretty hard hitting) and take the extra money left from the subs and put it into a JBL 600.1 to push them....trust me...it will hit. You could shop around and prolly find that whole set up for 300 to 400.

if its jammed force it - if it breaks in the process it needed to be fixed anyway

1. 103 decibals is loud but not terribly loud (not competition loud)

2. Just because they have a german like name dosnt mean they make a quality product or are even made in Germany.. Check DYohn's post on this company: click
