Hydiho I am currently looking for a power amplifier. The price should not exceed the 200 ? threshold, and it must be new. I have (still) the standard boxing in it. However, they will be replaced immediately later. possibly Infinity Kappa. The sub is a JBL, GTB 1200e. 250Watt RMS, (top 450). The whole should be a 4channel power amplifier. There are some of Helix, which are very cheap, or also of Carpower. But who has the “warmer” sound? or, who has, really more power? I know there are some questions, but you would really help me…… =)
