should i replace the one under my hood (the hc2400 will fit) or keep the stock one and add the hc2400 by the amp??

get a new head unit before any battery purchase dude.

find a friend with a digi cam and take us some pics man. this problem is starting to bug me. lol

haha i know man. trust me, it is bothering me too!! i have a camera and will take some pics when it stops raining. and i looked at the big 3 i did under the hood and i think that the grond off the battery is on a painted surface?? could this be a contributing factor? my ground from the amp is the best (cant get better) drilled through my floor and bolted directly to the frame! ill get some pics posted! i also gotta work though. ill try to get them up before i go to work...

i suppose i should make sure that the speaker wiring is done correctly. i was just too lazy to do that part of the install so i brought it to a local shop. maybe they made a mistake....

ya that is a major contributing factor. all your grounds need to be on bare metal. you want it scrapped until its shinny as hell. make sure it's fairly flat too, if there's a bunch of deep grooves from scratching it down too much then there'll be poor surface contact. get the paint in that area its touching clean, i recommend buying a cheap wire brush at home depot.

2 most important things right now besides fixing your crappy grounds are a battery for that amp, and a new HU. You should get something rated at at least 4v for the preamp voltage. i recommend alpine, eclipse, or pioneer.

as far as mixing batteries....there's a catch. you're SUPPOSED to have only the same kind (AGM, deep cycle, etc) and have them the same age. When they are differant kind of batteries, one of the batteries which isnt as charged as well will pull charge off the more charged battery. For a temporary setup, this isnt an issue, its when you have them like this for months itll start to harm the batteries over. for the time being get an hc2400 for the trunk, and after you get a new HU, get the front battery replaced with an hc600 or 800. if you reallllly cant afford a smaller battery for up gront, you can get either a battery isolator, or a solenoid. a battery isolator will direct the charge to one battery at a time, and a solenoid will disconnect the connection between the 2 amps when the car is off. i like solenoids more personally.....these things will range from about 30-50 bucks i think for a 300amp one. you can do one of these, but IMO you're better off with a new battery up front later on

when you scrap these grounds, the amp will be probly be able to pull more even though your preamp voltage is shitty. you NEEEED to get that 2400 for the trunk or else you run the risk of blowing your alty or amp trying to run that amp hard on an inadequate electrical.

you'd be suprised how often that happens.

i suppose it would make sense if they accidently wired it to 4ohms...then the amp would not be asking for much power, and definitely not enough power to drain my electrical.

correct.

i remember the very first system i had bought, i got a shop to install (im glad i learned how to install shit on my second). i told them to wire the sub up parallel for a 1 ohm load. they decided to wire it up to 4 ohms. so its definitely a possibility.

I recently had the equipment below installed by the only shop within 30 miles..my front l/r inputs were crossed, my rear left speaker outs were crossed, they grounded both amps to the back seat bracket itself!...not even scratching the paint. I took my ride back...I had to stand and point over his shoulder ( I wanted to kick his ***).

After rewiring the 4 ch amp and a decent grounding effort to both amps, ( I desperately need to do the big3 and add a battery) the hideous engine noise ceased to a minimum..LOL...I think the residual faint whine at 0 volume is due to the dipshit running 3 sets of cheap *** signal cables down the same side as the 4 guage power from the battery. On a suburban, thats what? 10 or 12 feet of bullshit.

Yea I guess the moral of this story is don't get lazy...this stuff aint that hard to figure out.

...or maybe just don't take your ride to a shop who sells house carpet in the same room as speaker boxes.

I could have bought another amp and some nice separates for what I paid those crackheads. //content.invisioncic.com/y282845/emoticons/verymad.gif.3f39c5c2fd57527b671fad3efdfac756.gif

yea, when i learned how to do it myself and how easy it is, i realized that i really wasted my money for that first install.

 

[LuvnThatBass 10+ year member]

well they did have a few things in weird places when they decided to redue my deck install (cuz the external stock infinity amp resticted my speakers from playing) to do an amp bypass. but i corrected that...i hope. but i checked the sub today and both positives are together and both negatives are together, so it is wired down to 1ohm. i dont know if this would play a part but my battery was making a funny noise when i was re-doing one of my big 3 wires. like rice crispies sound when wet (just not as intense). weird. here i got some pictures and stuff, camera was not too great, but you get the gist. my girlfriend has an older (cant be too old tho) sony h/u that she doesnt know how to function. you think i should try that?? cuz i am about out of ideas..
