I have Type R speakers all round, and a Cadence 5 channel amp. My amp is mounted on a removable board where the usual flap is seperating the boot from the battery.

I have the same as nsanity. My new amp is the JayCar precision 4x100, and it barely gets warm. My old amp had a fan built in.

I think you should check your power wiring or something... for it to heat up that badly during winter/spring you must have a slight short that is creating resistance/heat to the amp. Something like that.

Failing this, perhaps mount a big 120cm fan behind the battery cover off a relay that uses the remote wire. Could even mount it to the battery cover bit with a hole to draw in the air in the boot? Make another hole further towards the battery for air to come back out again, and you'd be at least circulating a bigger volume of air.

EDIT: when you get a new amp, check your wiring (+ and - ) with a multimeter. Make sure you get 13.8 or 14v positive and negative with the car off. Test again with the car on?

LoL...i would go with the fan idea.....that's if u could fit one thats 120cm :)

I find it strange that the amps dont have an overheat protection. Dont they all these days? (Maybe not the el cheapo)

If its the Power cables that are heating up and frying then your using too thin a cable...

Im looking at mounting two amps next to the battery, one ontop of each other in a kinda "shelf" configuration; ..with space inbetween for ventilation of course.... :)

I made a new one out of 12mm MDF from Bunnings, with brackets to make the right-hand side bend... Got loooong bolts and nuts to suit.

Haven't fitted it, probably never will. You would have to squeeze your hand over the top of it to hold the nut or bolt, depending on which way round you start it.

Then, it's so damn heavy, that putting it up with an amp on it is probably going to break the factory brackets for the stock cover. I don't want to drill holes or mount anything permanent, so this idea is kinda out of the window for me. =-[

I went and bought a smaller amp, which sits next to the battery, but try this idea if you like;

If you have a rear strut-brace, mount your amp with (thick) cable ties or some kind of clamp system. Hooks bolted through the screwholes of the amp might even do. (removeable amp).

Then make holes (for cable ties) or a bigger hole (for hook idea) so that you can mount your amp onto the strut-brace after the battery cover is in place.

Only thing to look out for is whether the bottom of the amp is going to be so heavy that it swings inwards and bends the battery cover thing.

amps get too hot? maybe they are running too hot? depending on your volume requirements go for the largest amp you can afford. for those who cranks them for a long period of time get the amp that double the power output of what you are happy with. so you have more headroom and your amp will run a lot cooler. i wouldnt recommend putting your amp together with the battery behind the cover as they will just heat up together (battery gets hot when they are being charged). the more room around your amp the better.

hope this help

bootr33.jpg

here is a pic of what i done last nite. I pulled out the floor carpet and back wall from the boot.

Then i off-centred the amp, so in case i need to get to the battery i still can. Next up there is a braket right in the middle of the boot, infront of the fuse box which i used to mount one side of the mdf board.

on the right hand side of the boot there are the 2 clips which hold the back wall up, the bottom one of them has a metal bracket which i used to mount the other side of the baord.

Then i put the carpet wall back up and mount the amp / fuse , now i gotta get it wired up when i get a chance later this week.

Mounting them on the side of the sub box isn't an option? I had two amps, one on each side of the sub box. The one running the sub only got really hot if I was cranking for half an hour non-stop.

With the wires on both amps covered by a flap of carpet (neither of which are finished in the pic, the carpet is lying on the floor beside the box) until a couple of inches before each amp, and the end plates on the Rockford, it was fairly neat too.

i have a little problem....

i'm running a 5000W Epsilon amp with 2 x 15" Farehiet subs. i'v built a custom box to fit the boot(only just fit) and had to put the amp underneath the box in the tyre well. (again only just fit). the setup isn't cery cosmetic and was wondering if anyone had any thoughts?????

There is really only two things you need to consider:

-Is the amp upside down? ....the way amps are designed and the position of the heat sink, they should be mounted vertically or right side up.

-Is there adequate ventilation? ...as long as you have room for air to move around the amp ur fine.

A third thing to consider may also be, how accessable is the controls of the amp...as you dont wanna be fiddling around.

      Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention

      So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34

      From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
