Hi again,

Another question. As i have stated i am going to run 2 8" subs each one being powered by a vibe vp2 amp Bridged my question is can i run a single channel to each amp from the head unit i.e using each sub as a left & right rear or do i run stereo channels to each amp and have the amp convert to mono for the bridge? in other words am i going to have to spend more money on another RCA lead and y Splitters?

Cheers Garith.

what head unit do you have?

[GaseJo]

I dont know off the top of my head ,Does it make a difference? It is not a well known make i got it off EBAY.

[McCARTHY]

whats not a well known make??? i only say because nakamichi isn\'t a well konwn make nor is becker and they are the best of the best when it comes to sound quaility form a head unit..... damn expensive too

Check if you h/u has a sub-out or if there\'s a switchable low-pass filter on the rear out or your amp as you don\'t really want to run the subs without one. If you select the cut-off frequency too high it\'ll affect the imaging...

Hi Probedb,

I am looking at having my box between suspension housings and under rear stut brace facing back of drivers seat as i have no rear seat just bins i will take the pull down flap out so the subs are visable. Doing it this way i should still be able to get to spare wheel if i need to without removing sub box.

Sounds sensible to me

Hi Elford Tim,

I dont knpw if it is an actual sub-out but there is rear speaker output left&right RCA plugs (one red one white) and in the manual it states that this can be connected to an amp. Thats why i was wondering if both these goto to each amp i.e RCA Y connecters to split them or can i run one lead to each amp making the amps and the sub connected to it in fact rear L & rear R

Cheers Garith.

if its a dedicated sub output, it\'ll say "sub output" or something similar (not trying to sound patronising so if it comes across like that apologies in advance!) What this is is an output that bypasses the internal amp in the head unit, allowing your amps to get the signal untouched.

if you only have the one output then by all means connect that to your amp(s)...you have the option of doing it two ways...

1) run the RCA cables to one amp, then (assuming your amp has an RCA output as well as the input) connect it daisy-chain stylee to the second and run a sub off each one.

2) run the RCA cables to the amps, then use a splitter to split the cables - 1 to one amp, 1 to the other. And again, run a sub off each one.

These are the simplest ways to do it IMO but im sure someone else will know other ways!

Which one you choose depends on the connections on your amps!

HTH!

Hi Trotter,

Thanks for the info.

I have got output on my amps but i think i will go with option 2. I will be starting work on it saturday. I may need more help as i progress.

Cheers Garith.
