I'm removing my sub soon and selling it (if anyone is interested its a JL12W-04) and will be running my amp just to the front splits to get a bit of bass from there. Before anyone says anything yes I know that this will not be an equal replacement for the sub but I don't really play my sub loud and its taking up my boot space. I'm after just a small bit of bass and sound clarity. I don't play my music that loud.

Anyway my question is - I'm currently using a Fusion FP4-1000x:

http://www.doranproaudio.com.au/products/d....asp?prodID=350

It's a relatively powerful amp and I've been told I'll need a fair bit of power to get any bass out of the fronts. Should I keep this amp or should I upgrade it to a different amp? I'm asking $380 for this one... so assuming I sell it around there what is another good option?

Thanks in advance

the amps alright, the amount of bass u'll get from ur speakers depends on the speakers itself not much the amp.

the amp has basic crossover functions like most amps do.

u will get more bass out of ur front doors from sound deadening period!

chances are..ur splits can handle a lower frequency than what ur playing cos ur hearing it rattle.

sound deadening adds weight to all the panels and little bits etc. so when a component is heavier, its natural frequency decreases.

the lower u get this natural freq. the lower u can play until rattling occurs.

i'd say keep the amp, invest $100 pref $200 in sound deadening the front doors, and ur fronts will be much more bassier than u've heard them before. not sub bass, but improved midd bass. depending on what frequency ur splits play. most splits r 60hz etc. but ppl tune them to 80 or 100 with a sub.

subs start at 20 or 40hz (cant remember which is start of audible human hearing) so ur missing out on a little there.

nav - thanks. I am going to sound deaden the front doors definitely, I've had a chat to FHRX about this too. My splits are the JBL P62 with split kit.... they've got a 45hz - 22khz range so I'm guessing I would miss out on a bit of bass but I'm not too worried as long as it still sounds relatively complete. I'm not worried about loudness of bass either. Hopefully these will do?

yup theyre nice speakers! ur on the right track then

what i'd do is do the deadening first, properly, then see how the amp performs.

that way u dont waste any time / money selling buying a new one.

IMO the amp would be nice quality.

what channels are u going to use? bridging any 2 channels? overpowering those splits in a lovely deadened environment would be very loud/clear and bassy.

      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.
