hey i have some problems with reaching moe bass or SPL from by new subs. with 2 type R's and 2x 2x50jaycar amps. each subs gets 450wrms each.
however this is not much louder then my 2 12
"venoms off a crappy sony amp.
when 1 subs is on its just as loud as both subs. they are wired the same same gaines everything. with SPL as number 1 pioity im very dissapointed with the lack of bass. can anyone help with this problem? thanks

Do you have them wired in phase?? Thats the only thing I can think of.

Yeh, sounds like a phase problem.

How are they installed? Which way to they face etc?

as above

try either changing the phase of one of them by changing the +ve to the -ve speaker terminal, or just disconnect one of them and see if u get more bass

phase? what does this mean?
i was playing with it today and this is what happens.

with the sub preouts from deck when connected to one of the amps the subs goes hard. when one of the rca in that same pair are split and into the smae amp its goes even harder. then swap from red to white rca and it goes lower again.
after trying all 4 single rca's from head deck only one of them pumps the hardest.
its not the subs cause ive tryed both of them?

how are you splitting the rcas again?

i assume you are using one set (1 red, 1 white) rca and splitting these into 2 sets (2 red, 2 white)....

when you split the red one, both becaome red, so one of the split ends goes into each amp, not both going into the same amp. and that goes with the white one as well.

ps. phase just means you have connecting the subs up right. ie, +ve to +ve, and -ve to -ve etc.

are these type r's DVC or SVC? how have you wired the subs up?

ok so in other words phase is just a word for mis matching the wires from the subs on the amps so they move not at the same time. ok no the subs are fine in fact i fixed the problem. it was the voltages from the rca's from teh head deck. for some weird reason 1 rca out of the 4 had a high voltage wear the other 3 didnt. so i just ran all amps off this one rca. weird but its works.
the subs are DVC 2ohms wird in series. cheers

So you are running two amps off one channel from your hu? Have you checked that maybe your rca's have died? Just try switching the leads around on the deck then if the same lead is keeping a higher voltage then the rest then Im thinking your rca's are stuffed.

yes but the leads are very expensive and only a few months old so i dont think so.
and besides they are fine for my speaker amp just not for the bass amps. anyway doenst matter its works and thats fine thanks
