Sa15= $590 to my door u15= $649 to my door thats less then $60 difference, my prices arnt like yours In USA 250vs350 100 extra on 250 is a lot 60 ontop 590 isnt even the sa v’s the x series is only $120

I’m starting here this a bit now, my local dealer thinks it will be fine, but after speaking to sundown direct they suggest the sa line and possible even waiting for the sa18 if I have the space not because I don’t have the power, I just won’t get any excision differences between the sa and u on that power where as I will have the power to use the sa18, now i wondering do I wait 4-5 months for the sa18 or push my electric system and try run a clean 1200rms amp, I have no hope powering anything over that as at current I have a kx400.2, 400.4 kx800.1 front stage is 600rms 2 sets 6.5” kicker cs comps on kx400.2 and kicker 1x crt8” on kx400.4 Rear door kicker cs 6.5 coaxel (on 50rms ea on kx400.4)

Seen them burp at over 15k

Got my answer, Thankyou, the u18 on that power isn’t to musical due to not enough power to control, so it’s a u15 for me, thanks

Edit Been out of the audio seen for at least 5-6 years, and there’s been a few changes, I was yep I’ll grab another sa series but then seen the new U series and x arnt much more now we have a local dealer Amp is kx800.1 so does between 8-900rms just trying to work out what’s going to be better/control on that rms? Biggest box I can fit 4cuft net 32hz 68sqin port, so controlling the sub is imperative to be musical u15, u18 and x15 ported (u18 is out of stock for 3-4months as I’m in Australia) everything else in stock also can’t go bigger on amp or this would be easy

You could alway get a lvl3 or 4 or even an xl Then when you have the elec to support a bigger amp, sell yours and get one to suit

no way thats way too much power, unless your @4ohm, and then thats fine but idd want close to 750rms on that in a tline (i think that at 4ohm is close to 6-650rms)

with 1000rms id run a single x10

captain we need more power

if you only running a single sub, why only get a 8" why not go 10,12,15 and why sealed, not ported, bang for buck is ported, and considering you have 400rms @4ohm to play with, a e15, or sd10/12 would be my options

q1-3500, 2 hdc315 d4 shac 2/0 and 2/0 big 3 is $1500 run the 3500@ 4ohm till you get some batts and alt down the line then drop it to 1ohm and you'll have more then enough side note, on a 130a alt if you put 2 batts in rear with a dash mount voltage gauge and watch the volts, you can run 1ohm with low tune like > -3

A 2k system can sadly be ran With 1 good rear batt and a good front With 140-180a alt up from If you start going over 2k then that all changes Another think you need to consider is how hungry are the amps The brz amps are very power hungry, If you supply the power they are a good amp, if your on the week side then you will smoke them Both systems you are looking at want 2-2500clean You'll get more cone area and motor force with the 2sa but more Xmas with the X So idd say littler to no difference between the 2 But they could be a huge difference once in a box Because that will make or break what you have So off that basses if I was you Idd work out some box designs and let the best one choses what you go for

if you want low end you have only 2 choices big ass sealed box or low tuned ported, because you have a set space to work within, idd go with ported what space do you have, measurements? amp is a t1500 idd look at a single 12 ported or 2x 10 ported, but depending on money, a single 12" wight get you a better outcome like a x12 or something, if you want to go sealed idd look at the the fiQ, but you'll want another t1500 to run 2 off them

are you restricted to 6k or a fuse rating to equal 6k
