I had these subs in my old vecta.. Was running them off the standard head unit.. But shamely havn't got these no more but they sounded mint! Still got the sponge bob though Bit catchy when it comes to the meets lol. Was running a Crunch P1400.2 amp to power these aswell.. In the vectra i have now.. I have ordered 2 lanzar max 12s 1000w max peak and 500rms.. per sub.. I dont know weather to go choppy choppy on the wiring again or do it properly lol.
