dylan117 Posted July 21, 2015 Report Posted July 21, 2015 hey everyone, i have a question that im just trying to get an opinion on. so, i have a 2000 blazer with the stock alt still (yes i know laugh it up LOL). but i have done the big 3 with skyhigh 1/0 OFC. i have just an average duralast battery up front, and an XS power D4700 in the rear. all wiring in shca 1/0. the rear battery is grounded to where the rear seats bolts to the frame/floor, is that a good ground? Im running an AQ2200 @.7 ohms. my voltage drops to mid 11s. is that to be expected with the batteries and wiring i have? do you guys think i need an HO alt for this amp or just a few extra batteries? thanks!
Rich Schenk Posted July 21, 2015 Report Posted July 21, 2015 I would reground your your rear battery to your frame. Ground your alt to battery. Upgrade your underhood bat to a agm and see whole your voltage is. I would also save for a quality ho alt.

reedal Posted July 21, 2015 Report Posted July 21, 2015 You should always use frame grounds for everything. You don't need a high output alt for that, but it's not like it would hurt. You'd probably be able to maintain a higher output and help the amplifier be more efficient. But, if you change those grounds to chassis/frame grounds, and upgrade the front battery to a AGM, then I'm sure you'll see much better voltage as long as gains were set right and you're not clipping the amp.

Copper07 Posted August 6, 2015 Report Posted August 6, 2015 I agree with first to replys, or just run your ground wire from battery to battery, similar to power, as most cars chasis grounds are similair to 4 gauge wiring. AGM battery would help as well, I dunno but he got 99 problems reading aint the only one.

There was a test done that shows up to about 3-4k watts a chassis/frame ground is actually better.Maybe someone can find the video, I'm terrible at navigating on my phone.

Broke_Audio_Addict Posted August 10, 2015 Report Posted August 10, 2015 If I have a full frame available I always use it. The only time i do a front to back ground run is in unibody vehicles because they have horrible return paths. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.
