I am in love. I have the SHCA EL-64 in the wife's RAV4 and I have these MRB-64 in our demo build. They build quality ks amazing, SQ is amazing. These little things are mini beast, On a underrated 80.4 ATM and will be on a synergy 8.4 at 2 ohm. I am in love. Don't think about it . Buy these! The El-64 are well worth it ad we'll.
