I'm looking for a 4 channel amp to power my mids and highs in a 2016 Mustang GT. Looking in the sub $200 range. Current speakers are JBL GTO609c 6.5" with tweeters and crossover, not being used (but may with amp) and the GTO329 3.5". The 3.5" and 6.5" are in the door and the tweets are in the A pillars. Currently have the factory 6.5" coaxial in the rear deck but will upgrade those as well with either the same 6.5" components or the coaxial. The amps I'm currently looking at is the Rockford Fosgate R400_4D or R300x4. These are both the Prime series amps. The other I'm looking at is the JBL CLUB-704 100x4 at 2ohm and 75x4 at 4ohm. The speakers are rated at 3ohm. Out of these, what would be your choice. For subs I'm running 2 RF P2D4 12's powered by a 15 year old Hifonics NX600 running at 2ohm.
