power feeding a texas star dx 667 v ?

I tend to think of "bigger is better" when thinking of feed wire. Min 4 gauge.
Caps aren't going to help much, If anything get one good batt for the front then Add another in the rear if it's neeeded. I ran a 4 pill tnt 600hd fine in a Nissan pathfinder with stock alt and a good battery up front. Don't over drive the amp. And like binrat said bigger is better!! #4awg min or larger. And have a good ground the same size as the power, I use the seat bolt, just make sure to sand the area and use a little bit of no-ox and it will be good!
mine is a red top some good 3 ga , the battery is on the passenger side and thats where it will come in 41/2 to 5 feet tops should feed that thing?
If you have not bought the 667V, I would save some money and just get a 500.
The 667 is a cranky beast of a amp, runs hot, and will not produce much more power than a 500. Your 148 will dive it just fine.
The 667 just eats up more current and makes more heat that you have to get rid of.
This is experience talking, been there, done that.
No one you talk to will ever be able to tell the difference between the two amps.
If you already have the 667, be very careful how much dead key/peak power you drive into it, put two fans on it.
The Cap is a waste of money for RF.

yes im ocd about the cooling i planed that from the go i already got the 667 coming, my 148f deads keys around 2 1/2 to 3 watts swing like 15 its a 15 watt radio on ssb im not sure
to be honest the 2 2879 pill amp i have is plenty, i get a new 667v in the box and some other stuff, could just sell a new in box dx 667v get some of my money back
one stupid question Jeff isnt the 667 a high drive? is 3 watts dead key on am too much?
im going to make a new cover right off the bat out of aluminum with fan holes, wire upgrade and wont run it wide open, this radio works so well you can talk all over with just the radio, dont know what ill do may keep my old 2 pill and sell the new one
Your biggest boost in power is your first 100 watts, then after that it get expensive and complicated quickly. Keep the 2 pill.
I'm a big fan of the idea that less is more in radio. I want to work the world on 100w or less, bit thats just me... the less power I have to use, the more excited i am to make the DX contact.
Keep your 2 pill and invest in one kick ass antenna system.
oh i know ive had many amps, back in the 90s i killed a 1992 dodge dynasty with a big texas star, it would kick the windshield wipers on while you were talking and the car would start pumping white smoke really bad if you were really telling a story the smoke would get so bad you couldnt see the car. lol Looking back as a veteran automotive professional i am today i know it was the RF messing with the 02 sensor and maf sensor and probably explains the sudden death of the electronic controlled transmission (them cars were turds anyways but this was 1995 and it was a 92 car i got a good deal on it) I had a 667 years ago too in a 79 chev pu and for some strange reason it went thru the HEI ignition modules like crazy, was an old carburetor truck with electronic ignition, needless to say i hope it dont kill my tundra or the toyota 4x4 playtoy of mine. lol
