From the stock head unit, I run a 4x60 RMS class D and a 1x650 class D hanging upside down under the package tray in the trunk. I put Kicker titanium tweeters in the stock upper door position, pioneer 3 ways (6 1/2 and 6x9) and a pair of Pioneer 10s. It's deafeningly loudc 135db! The key is efficient drivers (high number for 1w@1m) and for serious, and I do mean SERIOUS, rumble, an Epicenter Indash. Pretty ordinary loud without it, competition thump with it. Seriously tho, 450x1 was plenty but I replaced it with 650. Total cost $750.00 and it shakes!

 

In case anyone wants to know what the amp looks like (under the passenger front seat) for the 05 JBL sound system.

Thanks this saved me some time!

 

I have a 2005 Toyota Corolla LE also. it has a JBL in it. i can't get the Audio to work it in with the Wire Harness. i was told i could bypass the Amp all together. but i have no idea how to do it.

 

I only thought I had the 8 speaker system... after I got to checking my sticker I realized it was only the 6 speaker system.

The amp is surely a poor design. It is supposedly rated at 50wpc but I suspect as well that the rms is a measely 25wpc or less. I replaced it with a 4 X 50wpc Phoenix Gold Octane-R amp on the fronts only and it's a world of difference. I'm not overly excited about the highs but they will suffice. The 6.5's in the bottom of the door are awesome... (for a factory speaker)... they will handle the bass x-over at 50hz rather easily and sound very good. I was concerned that I might have to replace them but I will definitely keep them and consider replacing the tweeters with a soft dome later.

The schematic on the speaker wiring was right on the money.

You really won't need the wiring diagram... here are the color codes:

*THE POSITIVE/NEGATIVE WIRES ARE STACKED ON TOP OF EACH OTHER IN THE CONNECTOR*

RED/BLUE = POWER (30AMP FUSED) (THERE ARE TWO OF THESE IN THE CONNECTOR)

BLUE/WHITE = GROUND

RED/WHITE = LEFT FRONT TWEETER POSITIVE
BLUE/WHITE = LEFT FRONT TWEETER NEGATIVE

GREEN/WHITE = RIGHT FRONT TWEETER POSITIVE
BROWN = RIGHT FRONT TWEETER NEGATIVE

PINK = LEFT FRONT WOOFER POSITIVE
PURPLE = LEFT FRONT WOOFER NEGATIVE

LIGHT GREEN = RIGHT FRONT WOOFER POSITIVE
BLUE = RIGHT FRONT WOOFER NEGATIVE

BLACK = LEFT REAR POSITIVE
YELLOW = LEFT REAR NEGATIVE

RED = RIGHT REAR POSITIVE
WHITE = RIGHT REAR NEGATIVE

 

Just in case anyone ever searches for this amp and wants to know... it's under the passenger seat. I also have a wiring diagram that I will post speaker color codes for at some point in time (after I verify they are correct).

Its definitely under the seat, and I would be interested in the pinout. I'm thinking about replacing this amp or the headunit, or both. The amp seems like a cheap design that has 25W at the most per channel RMS. They say it is an "8 speaker system" but I've never found more than 6 speakers. 2 tweeters, 2 front 6.5", and the rear 6x9s.

Interesting...that's where the OEM amp for Gen3/Gen3.5 Camry was before.

Do you have that diagram by chance?

 

It seems this is what I'm finding... although I have not actually looked for it yet.

Now I need to get my hands on a speaker wiring diagram.

 

Can't say I know exactly, but it may be behind the glovebox, as that seems to be the common area to place all the OEM amps.
