Who sells all 3 ( sub,power, and rca cables) on ebay?

[keepingthe240]

I 'm putting an upgraded head unit in my 240 and found a good deal on a 10 inch sub and box for $85.00. I was up at Circuit city and they want $70 for the power cable, rca cable and the cable from the amp to the sub. I'm on tight budget and want to buy from one seller to avoid extra shipping costs!

ikesound... kickass deals with a pretty decent warranty

oh, didn't realize you only wanted wiring.. try knukonceptz too

How much power is your amp drawing?

I personally would run two sets of 12 or 10 gauge speaker wire for the power to the amp. You can get this at Lowes or Home Depot for ~$0.27ft.

For the RCA cables, don't get sucked into the marketing of gold plated connectors by Monster or any other big name company. El Cheapo TWISTED and shielded RCAs should do. You'll probably need a ~12 ft cable. That should cost ~$20.

For cable from sub to amp, the 12 gauge speaker wire should be fine

I'm planning on buying my cables from http://www.knukonceptz.com/ They have 2 amp install kits .... a 4 gauge or a 8 gauge from $18.00 The rca cable ...which one of theres do i need ?? Is it 2 males-1 male and 3 meters ?? THe box is http://www.circuitcity.com/ssm...il.do The sub is http://www.circuitcity.com/ssm...il.do A local guy has an amp on ebay i might pick up. Do i need a mono amp or a 2 channel amp and bridge it? My plan is to send less then $200 total (sub is $50 and box is $30) CAn i use home speaker wire from amp to sub ??

[keepingthe240]

I'm going to run a 100-200 watt amp

8 gauge is good for a basic amp.There really isn't any difference between home and car speaker wire, except maybe if the home wire has connectors already attached??RCA's from a Head Unit to an amp would need to be males on both end (usually).What kind of amp are you looking at? If you're going with a single sub, a mono amp or 2 channel bridged is really a matter of choice/availablility. I'd prefer a mono, cause it's generally built with a focus on the lower end of the frequency range, high frequencies require cleaner power to reach the same wattage ratings.

I think that's most of the questions, let me know if I missed any.

Also, NEVER use multiple strands of speaker wire as power wire, it will create more heat and be less efficient, no matter how cheap it is.

Do i need a mono amp or a 2 channel amp and bridge it?

It all depends if the amp can run at the resistance of the subwoofer. Some amps can run bridged at 4 ohms, some automatically runs at 2 ohms when bridged. So watch what type of amp you run for any particular subwoofer.

Good point, but working off the sub linked above (4 ohm), virtually any amp nowadays should be able to survive bridged onto a 4 ohm load.

[keepingthe240]

The sub will handle 500 watts at 4 ohms. THe box is 0.75 cubic feet. I would assume i need to keep the amp under 200 watts due to the small box. Any brand of amp offer good performance on a budget.

[Rex]

Subs are almost always rated at absurd numbers. Don't worry about matching the power unless you've gopt WAY too much power.

I'd suggest an Autotek amp (I almost always do), they offer several options, but look at the SX or MX models.

FWIW, a real 500 watts would kill that sub, but anyone that would buy that sub would not have an amp that can put out a real 500 watts.

(Edit: Sorry if that sounded snotty, just Pioneer is not renown as a big time sub manufacturer)

[base9se]

I always go for quality in my sound system. I leave my amps with a little breathing room. Currently, I have my Linear power 2.2HV amp running 1 Infinity Perfect Subwoofer at 4 ohms bridged. Considering the RMS Power Range is only 350W on the sub, but my amp can run nice and cool since it's capable of 600W. Meaning my amp doesn't have to work as hard, since it'll only be running at a gain of a lil over halfway.

[Rex]

BY using the combination you've mentioned you're following the one key to systems - wattage doesn't kill speakers distortion does. Rarely will anyone listen to clean power at volumes loud enough to create enough heat to "terminate" a speaker, but it's not uncommon for a cheap amp to kill mid-level speakers from distortion.

Nope, I've never run into this situation. It's like wiring an electric dryer in a house... You usually run two Romex 12 gauge wires for the 240 transformer. This is allowed by electrical Code and has not been found to be any less efficient then a single 10 or 8 gauge wire carrying the same current/voltage.

What you talking about?

Even if the amp is putting out a 2 Ohm signal, it won't harm anything to put a 4 Ohm load on it

First, pardon the hi-jack.

The gauge of the wire effects the "resistance" of the wire see the information below that shows the amount of amperage a gauge is reated to carry and that exceeding this value will create heat. Unless you have some way to make sure the electrical system in the car knows to only send 1/4 of the amperage through each wire??

Load Carrying Capacities (see table below)The following chart is a guideline of ampacity or copper wire current carrying capacity following the Handbook of Electronic Tables and Formulas for American Wire Gauge. As you might guess, the rated ampacities are just a rule of thumb. In careful engineering the insulation temperature limit, thickness, thermal conductivity, and air convection and temperature should all be taken into account. The Maximum Amps for Power Transmission uses the 700 circular mils per amp rule, which is very very conservative. The Maximum Amps for Chassis Wiring is also a conservative rating, but is meant for wiring in air, and not in a bundle. For short lengths of wire, such as is used in battery packs you should trade off the resistance and load with size, weight, and flexibility. (the last column is the amps for power)

What about a AUDIOBAHN 600 WATT 10" and a Pyramid 600 Watt Amp. Umm , when i'm hooking up my head unit to the adapter, do i spin the wires and use electric tape?

I understand what you're saying, but you know me, I be difficult

Using two sets of wires for power cable is similar to wiring two subs in parallel. How does the amp know to send 50% of the power along each set of wires? It doesn't "know" to do this, it just does.
