I needs some juice! Nothing too huge or powerfull just something that will do better than my Duralast "redtop". At the moment I will be running between 7-800ish from my sub amp and 100-125ish x 2 from my comp amp. But come tax time I will be running around 1200wrms for sub. So what are some brands and/or models I should be looking at? Kinetik? Optima? XS? I dont really know much about bat-trees. Help a brotha out!
FYI I will be getting a HO alt probably this secks-e one from DB
I dont really have any interest in running 3 batts Daniel lol. That just isnt my "style" lol. I like simplicity.1 batt,1 sub,1 sub amp,1 set of comps,1 amp for comps. I like to keep it as simple as possible. Those batts are freakin tiny tho huh?
get a decent deep cycle battery, and put it in the trunk. connect the amplifiers directly to the second battery for both pos and neg terminals, and connect the 2nd battery to the alternator via a battery isolator rated for greater than or equal to the peak output of the alternator.
Personally if you have the 4.3 I'd go for a large case. I'd take a factory large case ad244 over a high output cs130 from pretty much anywhere. There just isn't good idling output with that case. I've swapped an expensive 200 out for a 10 year old factory Tahoe alternator and had better idling output on a 4.3 Jimmie.
Troy I was on the S10forum and there is a sticky thread over there about the AD244. Supposedly it fits in an S10 but you just dont use the third mounting hole and you have to get a slightly larger belt. I went to the junk yard to try and get one but when I got there I couldnt remember what years and vehicles it came stock on. I thought there would be model numbers on the alts but of course there wasnt. My local pull-n-save has alts for 30 bucks too! Troy, could you please list some vehicles and the years that that alt came in? Or link me to some on ebay or somethin? Ive heard the AD244 does 100+ amps at idle and they made 130 and 145 amp models. I would rather have the AD244 anyways b/c it is way cheaper.
As for a battery,what would be my cheapest but best option?
I wouldn't use a deep cycle battery as your starter battery. It's not what they're made for, and the charging and discharge curves for a deep cycle are not at all suited to working as a starter battery.
Your battery, regardless of the one you choose, is not going to replace the need for that high output alternator. Get the alternator sooner rather than later. You're drawing a substantial amount of current on a mostly stock electrical system.
If you wanted to pull an alt from a 'yard I would look for a late 90's tahoe, suburban, Yukon, Yukon XL, Silverado, or other work truck. The better alternator (stock 140/150a) is on the GM conversion vans (some) also vans set up with lift for wheel chairs, and a pretty much sure bet would be the 03-04 suburban.
I called my local used car parts yard and they wanted 90 dollars for a used 03 suburban alt- what a rip off! I wouldn't pay more than 50 bucks for a used alt. It may be cheaper at 75 bucks or so if you haggle with them, but if the car has 200k miles and even an 03 is 7-8 years old, you've got a ton of wear and may end up buying another or repairing soon.
If you or anyone else is interested in brand new 'beefy' factory alts that do 100-110 idle and 170-180 peak I've got them for $150, with 2 year warranty.
Figure 40-60 amps for the car, so around 50 left over for the system. The average 1000 watt amp will only need 50 amps on music, and while the voltage will fluctuate the pauses in bass will allow the alt to catch back up so to speak. Anything over that I'd add a batt or larger alternator.
You can get some Marine Batteries at Wal-Mart for under $100 they are really nice for car audio systems and hold a good reserve...plus they are designed to take discharge and recharge to full capacity unlike conventional car batteries.....
