View Full Version : too little power upfront??

08-03-2004, 12:14 AM
I'm planning on getting a 15"XXX with a hifonics 1500bd for my 89 sierra. I'm just a little worried about not having the power upfront to match the insane amount of power that the lows will be getting. I have 2 pairs of Infinity Kappas running at 60w rms per speaker (sony xplod 4060-gtx 4 ch. amp.........eh, say what u want, it sounds and performs fine to me). What do you guys think? Should I look into beefing up the hi's and mid's, or will what i have work fine?

60w will get some speakers really poundin. you should be fine with 60w.

Kinda like my setup, 60.5cs components in the front and 692.5i 6x9s in the rear, run off a Sony Xplod amp that puts out 75x4. They should really get moving. In my setup with all speakers enclosed, they still don't have a lot of low end, but the highs will make your ears bleed. They have really harsh tweets without any EQ though.

alright thanks guys, i have another question though (for the sake of not opening up another thread i'll leave it in here). I have pretty much a stock electrical system, except the alternator and battery are both very new (the battery is an autozone bat that cost like 80 bucks, and the alt, well im assuming its w/e normally comes with sierras). do u think i'll need to do any electrical upgrading?

just do the big 3. http://forum.sounddomain.com/forum/ultimatebb.cgi?ubb=get_topic;f=5;t=007801
also check the alt wiring, mine was 6ga so i put 4ga on there with a fuse, bumped up the volts to 14.4. 6 ga is to small for the alt.

alright, i understand all of that except for the part about buying a new fuse to match the amp of the new wire (i think thats step 2). could u elaborate? oh, and since i guess the best thing to get is 1/0 gauge wire for this, wheres a good place to find a whole lot of this stuff for a good price?

http://www.weldingsupply.com/cgi-bin/einstein.pl?Next::1:UNDEF:OR:terms::PA cheapest place to get 1/0 ga. they have up to 4/0 ga. Ebay has all the connectors.
For the alt just get a 100-120a fuse for the alt.

alright thanks alot man

no prob.
im guessing you have the 104a alt, if there is any different ones.

I wouldnt know, I havent looked into it yet. Im on vacation in WA right now, so when i get back home I'll check it out and see what's going on with it.

they are set at 13.8v which you wont get max power out of your amp.
14.4 is what most alts do.

08-04-2004, 12:44 AM
and doing the big 3 will bump up the voltage to 14.4?

08-04-2004, 03:18 AM
the alt has an internal regulator. when i put 4ga from my alt to batt it starts out @ 14.4v then it slowly goes down to 13.8v. Thats not what i want but i dont know how/can't change it.
