Wiring Up Two Amps?

I'm just wondering how I go about wiring up the power for running two amps?

Am I am able 'daisy chain' the power wire from one to the next amp? Will that work?

So from the + of the one amp to the + of the next amp, and the same for the ground (-) ? From rough memory, that will halve the current (amps) draw available to each amp?

I assume running dedicated power wiring for each amp is ideal, but at the moment, I'm not really up for pulling apart the interior again for extra wiring. The gage of the wire already in place is already pretty hefty, about 5mm across so I don't think it could become easily overloaded?

My equipment isn't really high powered stuff and I don't crank the volume enough to go deaf, so can I get away with it for a while?

With +ve terminals, it should not really be a problem, but even though it will work i highly recommend using seperate GND cables, with the shortest path to earth.

A better way to do it is to use distribution blocks, one for +ve and the other for GND. This will also make it easier to wire up the amps, as fitting two 5mm cables into one termanal can be a prick.

Just be careful, if you are talking the actual copper is 5mm across or 4g then ok go for it, you shouldnt have problems, if the 5mm includes the outer sheath or 8g, then run a new cable, and upgrade the battery -ve cable (often overlooked) It may seem like a lot of work, but you really are a lot better off

Oh and the potential for current will be halved, volts are given, amps are taken

I can run two grounds, thats ok, as I am just grounding to the chasis in the boot. It's just the hassle of running to the battery in the engine bay on an R32.. If it was an R33, it would be no problems.

I have spade terminals crimped onto the ends of the wiring. I think I can rig in another to sit ontop of the other.

Thanks for the tip on the distribution blocks Al, might be worth investing in one of them to make it a bit easier.

remember to put in a fuse for each amp, dont run both of the same one.

Is ok to run off one..

Fuse is there to protect your car electrical stuff not your amps...

Thus why you have to put in a fuse as close to the battery as possible within 30cm if i remember correctly. Fuse size to put in is same as the total amp of all the amplifiers. Amplifier all have their own internal protection function, some has fuse on them some has more advance stuff like auto cut out.

      Slimline sub on the rear parcel shelf is doable. Pioneer TS-WX140DA is only 70mm high.

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.

      Misfire/stalling issues

      Easiest way to know is to break out the multimeter and measure it when cold, then measure all the resistances again once it gets hot enough to misfire. Both the original ignitor and the J Replace version. Factory service manual will have the spec for the terminal measurements.

      Yes that sounds right. Cars currently in the shop for the engine work. Will need to remeasure .. but yes I think I must be targeting 45cm from fender.
