have fitted my sub and amp now but have 1 problem; when i turn the volume up the sub rattles within the box. I have put pressure on the outer bit of the sub to check if its not screwed in tight enough and that made no difference. I have had to turn the input sensitivity all the way down on the amp and i dont feel like the bass is as deep as it could be. Any ideas?

Do I need to use the remote wire from the head unit? I have already connected this to a relay so my DVD player works without the handbrake on

I have now purchased a 10" sub and amp, would i go about wiring this up as if it was a normal setup (i.e not needing to bypass anything)Im assuming i just run a wire from the Battery to the new amp and connect the rest to the new headunit i installed etc. (basically do i need to worry about the old amp)

Thanks for your help.

ok Does the bypass cable plug into the amp in the slot where the previous stereo plugs into it? (the bigger slot?) and then unplug the speakers from the amp and plug them into the bypass cable?

No. You leave the amp completely disconnected. You don't need this anymore as your new head unit has a built in amplifier.

The larger connector you removed from the amp plugs into the bypass lead, the bypass lead then plugs into the ISO lead (or in your case will need joining with terminal blocks), the ISO lead then plugs into your new head unit.

Fitted the unit yesterday, I unplugged the bigger connection from the amp and plugged that into the bypass cable which i plugged into the head unit but the smaller connection is still connected to the amp as there was no where to connect that to. The stereo works and sound from all speakers. Where should the smaller connection from the amp plug into?

That lead isn't the same as the one that came with my Pioneer one. It should still be do-able but you will need to work out which wires go where, cut the connector off one end of your amp bypass lead and join the two together with terminal blocks (or solder if you prefer).

Getting the plugs out of the back of the amp is very fiddly and requires a lot of cursing and swearing but you can get to it without removing the dashboard.

There are two connectors plugged into the amplifer. One of them is simply the other end of the harness that went to your factory stereo (you no longer need this). The other one is the connector for all of the speakers/power etc. Plug your bypass lead into this connector.

so just replace the connection that is joined to the currect stereo with the bypass cable? i managed to get to the back of the amp and seen the 2 connections- need to wait for my headunit to arrive tomorrow to actually fot it

Pretty much. You'll also be bypassing the amp too as you will be disconnecting the speakers from it and plugging these directly into your bypass cable. The larger of the two connectors is the one you will be connecting it to.

i see you have the sport and yes you have an amp and if you had the se..you'd have an amp

as for the amp the thing you think is an ecu is the amp.....the cars ecu is under the bonnet....if you look in the work shop theirs plenty of guides how to fit the cable.......

the amp.....

Hello, im probably being incredibly stupid but how do i get to the wiring on the amp to plug in my iso cable?

Thanks for your help with this. just need to order the bulb from lexus. Your blue ones look good ;-)

Hello, i need to change the bulb that lights up the heating controls on my lexus is300. Do i just take the knob off to get to the bulb or do i have to remove the whole dash face?

Many Thanks

Hello im new here. I have recently purchased an IS300. Here are a few pics

I will take some better pics when i have time, these were taken quickly earlier on before going out in it.
