Kicker wants to up grade me to the SL5 Solo's. I have not heard any of the SL7's let alone any SL5's that I though was any good.My question is has any one heard these subs and can you say they sound good. I have read the specs and looks good on paper but I have not ben impressed with what I have heard. I think that those subs where under powered thats why they did not perform. Are these subs really that much better than Comp V.R. if things are done right. Any input would be great.
