Hi guys...im a newbie and this is my first post so bare with me

I need to install a new system into the sky but not sure about all the Watts and Rms stuff on the amp (im hopless when it comes to car stereo)

Anyways i have a 50Wx4 amp and i wanna run 7x10s, splits, and sub....i dont think this is possible. Can you guys help with recommending me a different layout. Do i need to get another amp? or is it better to run two amps? and how do you do it.

Also what size is the standard front speakers.

Thanks

Do you already have the 7x10s + splits, or are you still looking to purchase?

** Warning: the following text represents my opinion only :) ***

If you intend to run a subwoofer, I would recommend 6" 2way splits in the front (from memory the stock skyline front speakers are 6") and 6" 2 or 3 way components in the rear parcel shelf.

Depending on the quality of your headunit, if you were running only one subwoofer you should be able to run the four 6" speakers directly from your headunit using one amplifier to power the subwoofer.

As far as 'how you do it': the easiest way to hook it all up is to make sure that your headunit has enough RCA outputs for each of your amplifiers, you then do not have to worry with cable splitters which will only decrease the quality of sound further.

I'll cut this post short here as to not get too annoying... PM or just keep posting here if you've got any more questions, or any specific questions about what I've just rambled... or whatever... uhoh.. i'm still rambling....

6X9'S are good if you can't run subs. Rear speakers should just fill in the sound at the rear. Get a good sets of spits as this sets up the front stage.

Careful when looking at watts. Is it peak or RMS? Peak means jack. RMS is constant power.

You're better off getting a second amp to run the sub, and running the speakers of the 4ch amp. Reason is you get a better, cleaner signal from a dedicated amp than from your head unit's built in amp.

Also, don't bother with 7x10's if you're putting in a sub. Get a decent set of 6's instead.

If money is an issue, then run the fronts and sub off the amp and the rears off the headunit.

As Silver-Arrowz said, only look at RMS and not peak. To give you an idea most good headunits only put out about 20-25W RMS.

Are you gonna do the install yourself? VERY important thing in car audio is wiring, particularly when you throw an amp into the equation. Make sure you run at least 8g power and earth cable to your amp from the battery. All connections and terminals need to be done well too.

Could go on for ages. Feel free to PM for more advice.

Honestly do not bother with rear speakers just yet, unless you spend most of your time in the back seat you would want the sound stage right in front of you as much as possible.

Put your money towards a great set of splits and a decent headunit. Keep your existing amp (post details of it btw) and add a subwoofer that would compliment the amp that you have already. Bridging two channels of the amplifer to run the subwoofer would give you around 100-120RMS, so use a sub that is efficient at this input. Something like a JLW0 which operates happily at 125RMS ($172).

Run the remaining two channels of the amp to your splits and you are a happy chappy.

NB: what I wrote above is based on a small budget, but it will do very nicely.

Thanks guys for all ur replies...pretty overwhelmed that anyone even bothered since its my first time posting up a thread.

Well i took the advice and decided to buy another amp to run the sub. As for the splits i invested in a pair of good quality sneider 6" speakers and yups i did purchase the 7x10s already. The first amp that i had before is a kenwood 50Wx4 and the one i just got is a 200W 2 channel one (thats bridged i think)

Ive read a thread posted a while back and it says that 7x10s wont fit in the rear parcel...therefore i have to make another parcel tray.

Can u guys recommend an audio installer that does a good job since i want the wiring to be neat and all and where do i get the marterials to make the parcel tray and where can i get the carpet covering to match the car.

Thanks again

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
