Wel, 'snot that bad, you'll be pleased to know. Depends more than anything, on whether you want to be able to alter the fader front to rear at all.

If you don't give a damn about fader positions, then you can get Y-leads, which take a pair of RCA connections and give you two pairs. Use two sets of Y-leads and you have a total of 3 pairs of RCA connections. Obviously, all you have is 3 duplicated signal pairs, but you can at least connect everything up

If you want to have a fader facility, you need to go a bit uglier. You can get speaker-level to line-level converters. These take a speaker signal and give you a low-level signal, suitable for direct input to an amp. Of course, the down-side is the quality isn't quite as great as if you had a line-level signal in the first place, but they work well (I've used them before on other people's systems ) Autoleads sell them - I think you can get them from MCS direct online and they're not expensive.

Of course, the ideal is if you get a new head unit with two or three RCA ouputs, but I'm assuming the budget won't go that far!

Good luck

You could of course use a Kenwood KEC-202 or a Sony XEC-505 if you can find one as they are not made anymore.

Hi

Im considering buying a 5 channel amp at the moment, the amp has 3 RCA connections (front, rear and sub). However, i think my headunit only has 1 preout maybe 2 (its a Pioneer DEH-P6100R single cd headunit - anyone else got one of these and know how many it does have?). Is there anything out there that increases the number of preouts? Takes an input and splits it up. Or is it a case of get a new headunit?

Thanks

Ian

Right i have found out it has 1 preout that is switchable to a subout. The headunit is not much use then i guess...

Does the five channel amp have 3 inputs? Normaly they have just 2 sets of inputs,front and rear. The third set of phono plugs is normaly an output (through put). As said you could use a set of Y leads to split the signal but I wouldn't split it more than once. Normal low level output is around 1.5 VOLT, using Y leads splits that in half to 0.75 VOLTS so spliting that again will give 0.375 volts so what your'll be left with is, one phono lead with 0.75 volts and two phono leads with 0.375 volts. Amplifier inputs this low will give a much lower output in terms of watts RMS, a much higher risk of noise/interference and no fader.

Theres no disgrace using high level input (speaker wire input) if the amp you have in mind has it. I've done it on my own and customers cars with good results and this method is much less likely to introduce noise into the system plus you have a fader. You could use 2 speaker wire to RCA converters if the amp doesn't have high level input, I would use 2 of Alpine 4311. see the following address, click Alpine then accessories.

Thx for the responses guys, its been very helpful.

The amp im thinking of getting is the Maystar QXT500, see here for details, it does indeed have 3 inputs. I think im gonna get a new headunit after all, im not too keen on my current pioneer one anyway. Think i will get an Alpine CDM-7874RB, anyone have experience with this?

Also does anyone know whether a 6.5" speaker with a 70mm mounting depth can be fitted in the front of a classic shape scooby?

Thanks

...another way of getting three outputs is to use an equaliser like Kenwood's 4042a. This takes a single rca in and has front, rear and sub outputs. There's five channels of equalisation (gimmic) but more importantly a dual amp balancer (fader), sub level control and sub crossover frequency control.

Damn useful little bit of kit. Fits in the ashtray space. I'm not using mine if you're interested...

Chiark YHM can you just clarify that it takes in 1 input and returns 3 separate outputs

Does anyone know if comps with a 70mm mounting depth will fit in the classic scoob?
