My 2000 Toyota Celica GT-S Mods - Alpine amps and JL 10" Subwoofer

The Problem: The factory stereo lacks sufficient volume to be heard clearly and loudly from, say, 50 yards away.  ;-)

The Solution: A pair of Alpine amps and a JL 10" subwoofer

Cost: $575, installed.  Actually, Home Entertainment wired-up the amps, and I created the mounting brackets for the JL 10" sub enclosure.

Summary: The stereo now sounds almost tolerable. 

Home Entertainment (now Tweeter) installed a new Clifford alarm, and sold me two Alpine amps and a 10" JL Audio boxed sub.  The first amp, an Alpine MRVF303 (30Wx4) drives power to the eight factory speakers; the second is an Alpine MRV100M (100Wx1) to power the sub.  The stereo now sounds very good and clear, if not somewhat louder than before.  Perhaps by Summer 2000, I'll continue upgrading the system by upgrading the primary amp from a 30x4 to 50x4, replacing the head unit, and adding a CD changer.

Front Sub Bracket Detail
I fabricated the mounting brackets seen here with .125" thick 1" wide aluminum bar stock.  The front sub mounting bracket secures the front of the sub's box to the rear seat-back's mounting bolts.  In this configuration, the box is very secure and it doesn't shake, rattle, or bump around.

I am, however, up in the air on how to permanently mount the primary amp.  This is the amp which is currently affixed to the carpet with Velcro.  Yeah, it's a bit crude, if not effective.  I had considered mounting this amp to an aluminum plate on the right side of the hatch area, but I have yet to determine a practical manner in which to securely mount the aluminum plate.  If you figure this out, please let me know.   Right now, I don't tote much other than an occasional bag or two of groceries in the back of the car, so this amp is not in the way.
