Bad install cause voltage drops?

[dpu2014 10+ year member]

Well I got my stuff installed at circuit city before I met this website. I now realize that was a big mistake.

Well my question is, could bad connections from my amp to my speakers be a problem with voltage drops? Or is this not very likely because it doesnt take a rocket scientist to connect a wire to a speaker correctly.

Basically what could they have royally messed up that I should check?

My cousin had a Kicker 850.2 running bridges @ 8 ohms to a Kicker 10" L5 and everytime his bass hit that amp would drop the Voltage down to 8.12v and that amp would keep on kicking.. I couldnt believe it.... anyways I looked at his ground and it was running to a bolt on the Cab floor well everytime the bass would hit I would see a light flash by the ground and I was like WTF so i pulled up the carpet and the **** bolt was glowing red and everytime the bass hit it would get brighter.... He was lucky we caught it in time....; So check your grounds

check your grounds and what is your alternator rated it. I had about 1000rms and my lights were dimming pretty good, wasnt that low on the drops, but still was low enough. Get a bigger front battery and do the big 3. Problem solve.

edit: So with the alpine added on that 1000 how much rms are you offically running?

that truck should have a decent sized alt stock so you should not have a problem running what u have. I would of went 1/0 gauge on the 1000 watt amp. but i don't know if that would be enough to cause that problem. my friend is running 1600 RMS on his stock 98 silverados electrical.

i already have a yellow top. im doin the big 3 this weekend

hmmmmmmmmmm...... do the big 3 and see where it takes you. If that isnt good enough and your grounds are at the best possible location then get a back battery. Never hurts to have one
