Well ive decided my old system has bitten the dust once and for all and im lookin at some new stuff.
Im pretty new to the whole car audio thing and was lookin for some advice .
Ive narrowed it down to a few companies

up front.
Energy 5 1/4" Convertible Car Speaker (ENC525CV)
Infinity Kappa 5.25" 2-Way Car Speaker (50.7CS)
Pioneer 3-Way Speaker (TS-A1371R)

in back.
Energy 6" x 9" 3-Way Coax Car Speaker (ENC693X)
Infinity 6" x 9" 3-Way Car Speaker (9613I)
Pioneer 3-Way 6" x 9" Car Speakers (TS-A6972R)

and the boom.
Energy 10" Car Subwoofer (ENC10)
Infinity Kappa 10" Car Subwoofer (102.7W)
Rockford 10" Car Subwoofer (P2D410)
MTX 10" Car Subwoofer (TC710)

Im upgrading from JL audio evolution TR TR525-CX JL audio evolution TR TR690-TXi
2 10inch rockford fosgate punch stage 1 in a sealed box



like to hear what you guys think.
any advice is much appreciated.

Id go with the infinity speakers over pioneer, and ive never heard of Energy.

I dont know what Rockford subs sound like in a car (heard them on best buys showroom, but that proves nothing to me really) If theyre better than Infinity I dont know, but on that list, Id go with all infinity. Especially since its their Kappa line, i cant remember if theres a difference between Kappa/Kappa Perfect (of if theyre the same)... but its a higher line at any rate than the Refrence series, and I used to have those WAY back in the day and they were better than Pioneer stuff, to my ears.
