Bypassing Built In Amp For New Double Din Tv

[miles1980]

hi everyone. i was wondering if there is some1 that can help me. i have to bypass the built in amp in my is200 sport, to wire a double din tv.

thing is i have tried to remove the amp which is located behind the glove box but with the space provided the amp is to big to come out and there is not enough room for me to get my hand behind the amp to disconnect wires

anyone have any tips of me please. thanks jimbob

There's a walkthrough about how to remove the amp here. I found it tricky to get it out, even with the walkthrough, but I think I wasn't pulling the dash away enough.

But if you're putting in a new head unit, you'll need an amp bypass cable, which you can get off eBay. This connect the head unit to the OEM wiring and bypasses the amp.

Im going to ask a dumb question.. why would you need to by-pass the amp when installing new HU? only guess is that the standard HU has no built in amp?

Thats correct,

so the wires at the back of the stereo dont contain the usual speaker left right/front rear etc.

them wires go into the amp so in theory your just extending them to the back of the stereo.

Ahh, thanks. Thought it was quite standard to have amp built into the stereo, then again, i suppose the car does have 8 speakers to power. Is there a spec's for the amp? perhaps it could be used with the new HU (with modification)? much like connecting a 4 channel amp to an after market HU.

Don't know if there's a spec about, but there's a wiring diagram here, that might help a bit. This is for 2001 cars onwards, earlier cars may be slightly different (their diagram is here).

I really wouldnt bother using the amp.

Why would you say that? I've never heard what the sound quality is like so I cant comment.

Thanks for the links. Although one cant work out the specs from them none the less, its useful! [bookmarked]

Unless you have factory fitted Sat Nav then leave the smaller plug in the amp otherwise the Sat Nav won't work.

i have a sat nav. so that means if i ever come to changing the headunit i will have to keep the amp in.

yea it takes up so little room you will never notice anyway. The large plug comes off easy enough just leave the small one in place, you will also need Fargos dongle for the head unit wiring loom to fool the satnav into thinking the standard head unit is still in place.

well i have no plans yet to upgrade the ice or anything. just got a new headunit from lexus due to the error 3 so will wait once the error 3 will come back again.

thanks
