so what happens with folk who have 250-300 bhp thats not much room for the subs
im running 2 12" sony subs with max power 1200w each ( i think there around 700w RMS )but im running them off 1 alipne 1000w monoblock amp with the subs insatlled in series ( +ve from amp to +ve on 1st sub, -ve 1st sub to +ve 2nd sub and -ve 2nd sub to -ve amp
i have tried them in parallel but it kept tripping the amp out for some reason every time the bass jumped too high. i also tried running them independently ( 1 amp each) but this caused to much problems with trying to get them going at the same time as well as only one would adjust gain from the headunit although the wiring was spilt between them, something i couldnt work out same rca leads went to both and all 3 amps at the time were feed by a relay operated by the remote wire (used a relay as had neon light installed as well
so they only came on with the stereo)
as prince said if your going to use the boot your limited i currently have the preamp (lifts the headunit voltage up so the amps not working as hard currently set around 7v, head supplys 4.5), amp, power cap, distribution fusebox (1s unused put i couldnt be bothered buying a single one when i had a twin one anyway )and both subs in a sealed box which measures approx 900mm x 420mm x 400mm made outo 15mm plywood (better for the bass than MDF but more expensive) it weighs a ton but within 10 mins i can have it in the flat and have a empty boot otherwise ive still got use of around half of it
looking at redesigning it as want to sit the subs up to take up less room
but in answer to the original forum heading im using a 40amp fuse as 30a one blew while setting up the amps
in answer to the question
i would use 3 amps (1 mono & 2 2channel) or 2 ( 1 mono and 1 4channel)
so the mono can run the sub and the 2channel ones ( or single 4 channel) can be set up for front and rear speaker for better control
4 speakers in the back controlled by 1 set of channels or 1 amp and 2 speakers up front controlled by the other set or amp
should say just incase anybody doesnt know
- mono / single channel - only 1 speaker output, mainly for a sub
- 2 channel - 2 speaker outputs. 1 left and 1 right
- 4 channel - 4 outputs 1 front left , 1 front right and 1 rear left , 1 rear right
goes the same with 6 and 8 channels amps
