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 -
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 -

Just make sure you run 0g to that amp and not 4g As that amp can draw close to 130amps on its own -
I have a 2012 Pontic g8 with Bose I'm running 2x sa8v2 on a zx400.1 and the so overpower the factory that I set them with dd1 at -5db I originally had them on a zx750.1 and found it just waserent worth the alt upgrade as I was keeping the rest stock By all means fit what u want but I can garantee if you go that route the rest will happeni much quicker then planed

^ if that's the case 0.071x4 + 0.3x4= 1.485cuft gross, You could use some fill in the box if you can't get 1.4-1.5gross I've used the p3 in 0.2 with full and it was fine on rated Just don't expect it be as good with less then rated power, unless you have a on spec or bigger box How much power do you plane to put on the 4

Got my answer from rf Thanks for contacting us. The impedance is determined by the two mids connected, the tweeter is simply a pass-thru only. If you are using two 4 ohm mids on a PP4X the load at the amplifier would be 2 ohm, if you are using two 8 ohm mids on a PP8X the load at the amplifier would be 4 ohm.
