Dinho, I'm amping my Infinity References. There are loads of brands like JBL etc. The guy I bought mine off had a ICE'd Golf with a quality build. He just changed the design a bit. Now that you have mentioned it I should really test them LOL.

I replaced the rear 6x9s with Hertz ones and lost bass but gained sound quality. They were run directly from the head unit though.

Was you running an aftermarket headunit? I think if you ran them off an amp you would get more bass, I will see what happens. Which Hertz ones did you get out of interest, and how easy were they to fit?

Hey dinho, no I have always amped speakers so no issues there.

i think you might find wiring up the amp is easier than you thought. Toyotas are great for engine bay grommets. behind the battery there is a bung than appears behind the dash. If I could run an amp power cable AND cables for a A'Pexi Power FC standalone ECU through the grommet of a T23 Celica, the IS200 should be a doddle.

My main concern now is how to mount the 6 x 9's. do i need to glue, drill new holes or use nuts and bolts. That's the question i'm still waiting to be answered.

Jay hows your 6x9's goin, have you installed them yet? Ive bought mine so will soon be installed hopfully at the weekend! Did you have to take the seats out?

You will have to remove all rear headrests, then the bottoms (seats) of the rear seats, then the backs. Then the inside rear quarter trim panels. Then and only then can you can remove the parcel shelf/speaker grills to gain access to the rear speakers!

You may well loose bass as the stock rears run at 2 ohm.

I love your logic that is was easy on a Celica so much be easy on an IS! It isn't too hard, but the I'd say the Celica was a little easier.

As for mounting, you should be able to just screw them in. Though has the spacer issue already been addressed? You will probably need spacers for the new speakers' magnets to clear the boot mechanism. Though I chose to remove the mechanism and fit a gas strut (as used on the boots of many other cars) bolted to the back of the seat.

@dinho - No I have not installed it yet. I did the front components a couple of weeks ago, but suspension and brakes have kinda taken priority. Once they are done, I will probably do it this weekend.

@stoney - I have a pair of spacers so it should be fine.

Out of interest, what dampers did you use for the bootlid?
