KickerKid58 Posted January 22, 2013 Report Share Posted January 22, 2013 '99 Honda Civic. Stock 75 amp alternator stock batt up front and XS XP950 in rear Big 3 in KNU 1/0 and 1+ 1- run of XScorpion 1/0 to back 2500watts @ 1ohm plus some 55w hids with a lil bit of draw lights on, heat blasting and system cranked I can easily hit 12.0 daytime on the highway tho....usually bottom out around 13. Great Thread. I might be getting a jeep this summer and their stock alts are 160amps so im wondering if lots o batteries will work for 4-5k or if a good quality h/o alt with fewer batteries would be more cost effective.. 06 Jeep Grand Cherokee 2 DC Level4 12" Soundstream TA1.3000d 4 RF Punch 6.5" Components 2 RF Punch 3.5" 2-ways RF Prime 400.4D XS Power XP950 +&-run of XScorpion 1/0 OFC My Civic Build Link to comment Share on other sites More sharing options...

audiofanaticz Posted January 22, 2013 Report Share Posted January 22, 2013 * 2001 Cadillac Seville STS * Stock 140amp alternator * Stock battery location under rear seat, stock battery swapped out with a Stinger SPV70 * XS Power D3100 in the trunk. * Sundown SAZ-4500D wired at 1ohm to a pair of Sundown SA-12s * Normal/daily voltage with the car at running temperature is 14.9volts * Voltage drop at idle is 12.1volts, that is with the system playing full tilt, all headlights/running lights on, all the dome lights on, heater on max, rear heat on max, both the front and rear heated seats turned on hi. * Due the the stock battery under the rear seat, wiring is not as typical as an every day car, so you could say its the big 3, but its just how you would wire the car properly if there was no such thing as a big 3. * Wiring is all done in Audio Technix 1/0gauge CCA wire. I am running 1 positive run and 1 negative run from the alternator to the trunk. -Positive wire starts at the alternator, it runs maybe 4 feet to the factory fusebox under the hood, where it splits off and runs to the rear stock battery location under the seat, where it splits off again to go into the trunk where the d3100 is placed, and then feeds the amp. All factory 4gauge wiring is left in the vehicle hooked up. -Negative wire starts at an mounting bolt for the alternator, runs straight back to the stock battery location under the rear seat, the battery is also grounded to the chassis with the factory 4gauge ground, as well as a 1/0 ground. The negative wire splits off the rear seat battery and goes into the trunk where the d3100 is, and again is also chassis grounded, and of coarse the negative wires for the amp are connected directly to the D3100 Link to comment Share on other sites More sharing options...
