Aliexpress is really cheap too, but takes 3-4 weeks to get here. I don't think I could afford car audio in Canada lol. Seems like it's all 2-4x more in price. Almost worthwhile to buy, have shipped to your relative in WA, then drive over and pick up. Could get subs, amps etc for over half price. For the 2 infinity kappa 1200w subs I have and the SQ S1-1250 Amp I spent $350. Amp is 1,300 watts rms, guess will see how I like it since it isn't here yet, but should be easily 300 more watts than I have and peak when bass hits will be stronger since it should get like 1600 watts. I really like it has clipping indicator and seen they are reliable. The infinity 1200w subs have really clean sound, bass notes all sound better than expected, is exact spec for my box and seems really well made, the carbon fiber cone is strong. I fd up when screwing in screw for sub and slipped, bounced off the carbon fiber, could have been bad if paper. Can't wait to finish this up. When done will be this: 2015 8.4 nav radio(my trucks a 2013), Amp pro ch41, stock alpine Amp for mids/highs, the SQ, s1-1250 running the (2)Kappa 1200ws @ 1ohm. The dual 12 fiberglass sub box, jbl gx 302 in each corner, infinity 3022cfx in center, jbl power series 6x9 rear doors, Kenwood 2ohm 6.5s in front doors, butyl deadener doors and back behind rear seat and misc closed cell foam for rattles where needed. The big 3 electrical upgrade and 120 Amp fuse, 2g run to Amp for power and ground and Agm battery. I have a ax-dsp also, but don't think it's worth adding unless I replace stock Amp.
