depends on what you want to run it on ?

how loud you want it?

cost range?

brand loyalty?

size?space you have

what ohm load your running it at ?

how much do you want to spend on wiring upgrades and alternators, battteries ?

do you want class, A, AB, D, Hybrid ? why mono ? you can do stereo amps as well ?

do you want sound quality, and control of your woofer ? or just bass

what size woofer, what box is it in ?

a 50 dollar 1500 watt mono block is nasty

and 2000+ dollars would one be fine

but Im sure as you can see you need to answer more questions to make a informed decision and be happy with it

why 1500 watts, ? RMS or max power ? real world ?

good power for a mono block, is 24,000 watts at 1 ohm. but you battery load would be retarded

powering what ? a 900 watt sub from jensen or amp from jensen ??

the sony is a small step up at best ? it wouldnt be my first choice for a budget sub amp.

Id suggest just getting a 900watt RMS (stated) or higher Kenwood mono D amp. Assuming thats a DVC/2ohm sub. They are cheap and dont sound too bad and will put out about 400RMS at 60hz at 2Ohm stable which is probably more than a sony "1500" could handle. But in all honesty sony dont really make high power subs so any $250 amp is likely to max it out

it depends on all the thing i asked before?

and what kind of box the subs in

how loud do you want it?

do you have the subs model or ohm load, how many voice coils?

yada yada yada, as above

are you running a amp on the front speakers or deck power?

kenwood is decent cheap amp ?

the new sony speakers are rated around 1500watts "PEAK" power and around 400 rms, for anything more then a few seconds in the wrong box or clipping will kill the woofer ?

what are you trying to do exactly ? louder? deeper ? clearer ?tighter bass ?

it might be a waste of money to drop a big amp on a poor sub in a generic box , mounted wrong or x-over wrong ?

Are you after sealed or ported? how much space are you willing to lose? because if you want "reasonable amount of undistorted bass" your going to need to tune the box which Sapphire would be able to tell you all about

ok, well its a four ohm sub single voice coil, just want a resonable amount of undistorted bass

Like before

price range ?

amount of space you want to loose ? what kind of box do you have now ? sealed , ported, factory , generic , approx how big is it ?

sub model ? so I can see the Thiele parameters

what kind of music do you listen too mostly ? how loud ? and what source is it most of the time, MP3 , radio, CD ? some music lends itself to a different box , and same with loud volumes, safer for the woofer

what head unit type are you running, ? do you know the specs for line out voltage ? because if your amp needs high level inputs or converter that will make a difference ?

I take it this is in a R31 4 dr ?

do the front speakers use a amp or deck power ?

without answering these questions its hard to help you find options , just throwing a 2000 dollar amp on it wont make it sound better if its in free air, or the deck has convertors and playing MP3 at low bit rates

this might be as simple as a few bucks worth of poly fill, and reseal the woofer, change the crossover point or face the box another direction to make it sound better ?

      This is the GTR fuel pump. Yellow shows 12V, orange shows earth. The ECU provides the earth to activate the fuel pump relay. The ECU side of teh relay will pull low when the ECU activates. This is the RB20 fuel pump. Almost the same, but a little simpler. You can see I indicated (above) where the 12V line goes down to the RB20 diagram on the overall diagram, whch shows both RB26 and RB20. This is where I show it coming in on the RB20 diagram below. You can see that the dropping resistor is handled differently. When the fuel pump control is not providing earth to the pump, the pump earths through the dropping resistor and thus runs at lower voltage (some is wasted over the resistor) and runs slower. I showed that "not 12V and not quite earth" portion of the wiring in a paler orange. The rest of the wiring that I did not colour on that little section below the pump would be orange when the fuel pump coontroller is providing earth. This drop is handled inside the fuel pump controller in the GTR. Regardless, you can see where 12V is supposed to be, where earth is supposed to be. The key on prime is via the ECU providing the pump for only a few seconds the switching off. You should be able to see that happen.

      Yeah so when you turn key to IGN the fuel pump should run for a few seconds. If you find the fuel pump relay (and have a multimeter, and a second person) to can check the relay inputs.  One trigger pin should be either fully earthed  The other trigger pin should get 12v from the ECU for say 3 seconds when you turn key to IGN, and at all times that key is at START (note, I said this from memory, it may be the other way around, ie one pin always has IGN 12v and the earth has continuity to earth when you turn the key) One Pin should have a good battery voltage The last pin goes to the fuel pump + Also note that if the power to the relay is good, and the relay is working, it is worth checking the pump has a good earth too. There is a computer in the standard system that increases the earth resistance to slow down the pump when not required, pretty old school and it may have failed

      All this talk about fuel and fancy ECUs, meanwhile my poor old R32 has neither.... When the ignition is turned on, should there be power running o the fuel pump constantly or just for the few seconds it usually takes to prime the pump? About to go have another look at it, have watched some YouTube vids on how to use a  multimeter and looked at some wiring diagrams but really have NFI what I'm looking for because electricity is invisible

      Yuh....but weren't all the supertourers, except maybe the Audis, FWD? I don't recall any of the others being AWD.

      They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox) They ran them in Oz Super Tourers too https://www.supertouringregister.com/register/vehicle/212/ (I'm so old I remember racing with Matthew Fox)
