Hey

I bought some FOCAL splits over the weekend, which I will be putting into my R33, I am just trying to source and amp to power the splits and rear FOCAL speakers also

The amp I have come across is an ALPINE V12 MRV F340 4 channel, just wondering if anyone can tell me by looking at the below specs if this amp would be well suited to my speakers or would I be better off going with something more powerful

FOCAL Splits:

6.5" component speaker set

165mm (6.5") component speaker set, all weather woven fibreglass cone with separate crossover and tweeter level control.

Max. power handling: 120W.

Nominal power handling: 60W RMS.

Frequency response:60Hz-20kHz.

FOCAL rears:

6.5" co-axial loudspeaker set

all-weather woven fibreglass cone.

tweeters swivel for optimum imaging in your car

Max. power handling: 120W.

Nominal, power handling: 60W RMS

Freq response: 60Hz-20kHz.

ALPINE amp:

Amplifier Type: Multi Channels

Bridgable

RMS Power at 4 Ohms: 55 W x 4

RMS Power at 2 Ohms : 65 W x 4

Performance:

Frequency Response: 10 Hz - 50000 Hz

Signal to Noise Ratio: 100 dB

THD at Rated RMS Power: 0.08 %

Crossover / Equalizer

Low - Pass Frequency: 30 Hz - 400 Hz

High - Pass Frequency: 30 Hz - 400 Hz

Other Features:

MOSFET Circuitry

If anyone else has something to recommend please feel free

Thanks

i have always thought a good policy was to have the RMS values of your amp and speakers roughly matching.

so 55w RMS x 4 should be fine for your 4 60w RMS speakers.

Focal speakers ROCK by the way :D have a set in my 33. well worth the coin

Hi Abu,

What model splits are they, 165 A1?

That amp looks fine but I would recomend running the amp bridged to the 2 front speakers and run the rears off the head unit. It is always best to have more power on hand then then the RMS of the speaker, also you don't really need much power to the rears as they only there to provide a bit of fill for the people in the back.

PS good choice on the Focals, i'm running K2Ps in my car and love them :)

Hey Ric

Thanks for that, I just wanted to make sure if it would JUST power then or if they would comfortably power them but it seems like it will do the job. I can't complain for the price really

haha I have some high expectations for these speakers but not doubt they will impress :D

Hey man

Yep running the 165A1 at the front and 165CA1 at the back

No worries, I might just hook them up normal and see how it sounds, if not then I will do it your way. I spoke to the guys at the ALPINE store where I got all my stuff and they said the V12's are pretty powerful and they usually push out a little more power than whats on the spec sheets so it should push it fine

K2Ps! Nice man!

Thanks guys

    • As far as I can tell I have everything properly set in the Haltech software for engine size, injector data, all sensors seem to be reporting proper numbers.  If I change any injector details it doesnt run right.    Changing the base map is having the biggest change in response, im not sure how people are saying it doesnt really matter.  I'm guessing under normal conditions the ECU is able to self adjust and keep everything smooth.   Right now my best performance is happening by lowering the base map just enough to where the ECU us doing short term cut of about 45% to reach the target Lambda of 14.7.  That way when I start putting load on it still has high enough fuel map to not be so lean.  After 2500 rpm I raised the base map to what would be really rich at no load, but still helps with the lean spots on load.  I figure I don't have much reason to be above 2500rpm with no load.  When watching other videos it seems their target is reached much faster than mine.  Mine takes forever to adjust and reach the target. My next few days will be spent making sure timing is good, it was running fine before doing the ECU and DBW swap, but want to verify.  I'll also probably swap in the new injectors I bought as well as a walbro 255 pump.  
    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
