I'll be setting up a DX500V shortly in my '97 Ford Ranger which has a 95 amp alternator. The radio I'm using is a Galaxy 949 which I'll set to probably about 2-4 watts for the 100-125 watt dead-key.
Currently I'm using a Palomar that's dead keying 80 watts with no dimming or other issues...just lots of bleedover into my stereo speakers which leads to another question...do you guy's ever use your stereo speakers as talkback?!?
Do you guys have any idea if the stock battery/alternator will be able handle the Texas Star? Thanks in advance for any info. |

Timebomb,
I would guess your Palomar pulls around 14 amp at max power or a little less.
My Texas Star 500V is advertised at 45amps.
The stock ford ranger alternator and battery may not be enough as you will need to wire it directly to the battery.

the 500v may pull around 50 amps, the radio 4 or 5 more. the 500v is built to take nearly 10 watts carrier input to make about 120 watt dead key, such as from a dual final export radio. (the ts dx667v was made for single final/stock CB's). so, you may not see 120 with 2 watts in. same with swing from the 949, it may not be enough to see 500 PEP from the amp. either way, the 95 amp alternator SHOULD be OK, with stock lites, wipers & heat/AC on full blast you MAY see some voltage drop, and decreased 'key time'. make sure you have at least 800CCA battery with longest reserve time possible. a small 575 cca battery won't cut it. make sure the charge wire (alt to batt) and ground, as well as amp power leads are short as possible & heavy guage as possible, minimum 6g for amp if less then 10'. |

My battery is rated with 650 cca's. I figure since I'm not necessarily looking to get the absolute max out of this amp, I'll probably keep things on the low side, and have a little head room...or upgrade the battery if needed. Are there any negatives in not using the amp to it's full potential?
I'm currently running the radio AND amplifier's ground wires to a chassis bolt right near the battery. I'm thinking I should shorten these, and attach them to a seat bolt (near the amplifier), where I currently grounded the amplifier's chassis. I'm thinking this might help eliminate my stereo speaker "talkback". Am I on the right track?
I am currently using 10 gauge power cable on the amplifier, since I could only fit this size through the firewall plug. If I pull the radio and amp's ground wires back into the cab and connect them inside, I should have enough room to squeeze some 6 gauge through the hole.
Slowly but surely I think I'm getting this figured out. Thanks again for the help. |

this wont hurt the amp just ya wont see the
the kinda wattage ya should.i agree with pat
for your radio the 667v is more suitable.
if this is overkill for ya look into the t.s400
your radio will drive it really good and wont
have to change altenator.this is my favorite
for your type of radio

Another question...if I run the amp's power lead straight to the battery, and the ground to a seat mount chassis, should I cut the extra length of the ground wire or can I just roll up the excess?
I'm still trying to figure out why I'm bleeding into my stereo speakers so bad. Is this common with insuffient grounding? |

Timebomb, Cut the amp ground wire as short as possible. If the amps ground wire is to long it will radiate like an antenna and this could very well be the reason for the bleedover issues, not to mention many other possible problems like wipers on and getting shocked. You're running a fairly large amp so bleedover into the speakers is to be exspected somewhat. You could try rerouting the coax also, away from other wires in the truck.

yea maybe i missed it but what type of antenna and coax ya got.cheap coax could give ya trouble.
id run both leads to battery,then a addinational
lead from a screw on the amp to the seat bolt ya mentioned.keep this on short as possible

On my first attempt at correctly installing the DX500 in my Chevy van I ran both power wires 8 feet long to the battery. Results were horrific, shock from the mic, wipers on by themselves, it was a mess.
To fix this I cut the ground power wire down to 2 feet and bolted it to the seatbelt bracket that is attached to the vehicle frame. Been perfect ever since.
The idea length of a cb antenna is around 8.5 feet. The closer a ground wire gets to this length the more it will act just like an antenna causing all kinds of problems.
So if you have enough extra ground wire to roll up and tuck away then I would bet you have at least 8 feet considering all the bleedover trouble your having.
Get rid of all that ground wire and you will get rid of most if not all the bleedover.

The antenna is a Wilson 1000. I know this is not ideal compared to a "hard" mount, but the SWR is surprisingly ideal with a meter before & after the amp. I'm going to experiment with the power cables, and I'll post how it turns out.
So far the 500 is working great. Deadkeying 130 with 5 watts. No headlights dimming or any other problems except bleedover and terrible ignition whine. Time to add some grounding and possibly a noise filter. |

for whine may try a magnum filter cord 3pin
make sure your nb/anl are on.the wilson 1000
is a good antenna
