8 guage is only really for about 600w, so id go for 4 guage this will take 120amps of power, simply your amp should have 2 x 25 or 2 x 30 amp fuses making 50 or 60 amps so basically you could run two amps like this on 4 guage meaning you can upgrade later

just running it on 2 bridged at present. i'll just get an rca splitter, join it up 2 the other 2 channels, bridge it and wire up another sub. Will i have 2 go 4 4 gauge or will the 8 be ok ?????????

how are u running the 1 u have at the moment? 2channels bridged together or all four channels bridged together?

i was thinking it would.

don't know really, but it is 2x600 MAX bridged. So i'm expecting bout 200ish RMS. It runs the one i've got fine. V. punchy an loud

do u know wot the RMS of the amp is? would recommend using sub box of same size and type cos otherwise it will sound sh*t.

I've currently got one of these

in a 1.3 cub. ft. ported box

being powered by one of these


will the amp have enough in it to power another TSW-305C ?? they run at about 400 WRMS.

Will i have to use another ported box of the same size to match the other ?? or doesn't it matter

Will 8 gauge power do, or will i have to plump for 4 gauge

Soz about all the questions !!!
