Do i need a CAP ???

Hey guys,

At the moment i have the following system, Im after peoples opinions on what i should do



Kenwood Mp3 50 x 4 H/U

Clarion SRS1725 Splits with In-Line –6dB/oct Crossover Network

Response 150WRMS x 2 (Bridged to 400WRMS x 1) powering Sub

Sony Xplod XM222MK2 (35WRMS x 2) Powering the Splits only

Kenwood 12 in Component Sub (200WRMS)

I have 4G power cable running from the battery to a Distribution block then run 8G cables to each of the amps


Would my system benifit from a 1 farad Cap, I also want to install a Digital Voltage/Current Terminal block just to see what the voltages and amps are like

With my splits is there any benefit from installing a seperate adjustable crossover or isnt it worth it

On the sony amp there is no adjustments to the gain just a level adjustment, on the response amp i have all adjustments set to about 3/4 of the max settings give or take a little .

i have had the woofers in the splits starting to distort/Clip a little so have adjusted the level down a bit

I listen to alot of Dance, Electronica etc etc (The faster paced music) just so you know

Ps, I have also posted this on FF.com.au

Thanks,

Ash

Not really, not with those amps.

Yes. What you are doing at the moment is amplifing the whole signal, and then removing some of it (the bass). If you put a crossover before the amps, you will only be amplifing the signal that you want. (i.e. - more for less)

Re: Do i need a CAP ???

The old range of jaycar amps (not jaycar Responce) were rated at 400WRMS, What do you think they should be

I have decided aginst the cap after reserarcing it a bit more


Could you give me any advice on what crossovers i need, At the moment i am getting the feed for them from the high level input on the rear factory parcel shelf speakers, I know this isnt really desirable

Re: Do i need a CAP ???

Sorry i was wrong with the power rating of the amp, It is rated at 450WRMS X 1 when bridged into 4 Ohms with a THD of <0.08 @ 1 Khz

Max current draw is 56A, Why do u think that i am only drawing approx 20A from this amp and approx 12 fromn the baby sony unit


Sorry again

Ash

Feed everything from the RCA's (I assume your headunit has them?)

Re: Do i need a CAP ???

the splitter wont fit in the space provided at the rear of the H/U so the only option would to be fitting it at the amp end and maybe redoing all the cabaling there, If i do buy a splitter isnt that going to half my voltage etc

Re: Do i need a CAP ???

you have to remember amplifiers are designed to work in a range of input voltages. yes it may (and i say may) slightly reduce your output, but it probably only means you will have to turn up the gain on the amp. to be honest i doubt it will have that much impact at all.
Just rewire it as you said and it should be perfect.

Re: Do i need a CAP ???

so running the splits off the preouts will be a great improvement over running them from high level inputs , I thought so LOL
