I’ve been wanting to do a big build for some time now . How could one pick a brand do use though . I’ve been doing research on and off for years . I bought 1 skar evl 15 d2 wired down to 1 ohm. It’s been almost a month now and I’m very pleased so far . The all around bass sounds great with a big punch specially for the price . I paired it with a taramp 4K and it’s so far been taking every bit of over 2000 rms with almost no temperature change on the speaker and dust cap. I have it in a Q bomb single tuned to 34hz. Skar is the best bang for your buck so far for me .
