Power amplifiers: A 4 channel power amplifier, on which 1600 Watt stands from time austria (no sub-output, frequency response not adjustable) A 5 channel power amplifier incl. subwoofer output from Gelhard (frequency response for all channels separately adjustable), watt power I can not say exactly, but is not much. Parallel to the power amplifiers is connected a 1F Powercap. Boxing rear: bass roller “Jensen Rocket 1000″ – 360 Watt, 25 cm diameter 3 ways 6”x9” coaxial system, 2 times ~ 150 Watt 2 ways 4”x6” Coaxi al System, 2 times ~ 120 watts (not yet connected) boxes in front: none yet, but there’s still a 2 way system in there, possibly also a mid-low driver and a tweeter separated – what can you recommend there? Currently the bass roller at the sub output hangs from the Gelhard power amplifier, also rumps quite well, but it still doesn’t reach the limits. Where do I best connect what? Should I set another monoblock for the roll in, or do my components suffice? PS: My license plate vib How stupid because of the bass roll, I thought about building foam between body and no sign. Do you have a better idea? Silicone? Thanks in advance greeting Wobl
