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

Edited by sapphiregraphics

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.

Edited by sapphiregraphics

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

Edited by deano3350

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 ?

about 300 bucks maybe more, space im happy to loose most of the boot, the box is a 50 litre ported, its an xploid 15 1500w thats all i know, i tend to listen to linken park, acdc etc in high quality mp3, im running a sony xploid 4x45 watt?, front speakers are deck power

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
