I think the local shop screwed up the install, but I can't tell.

not sure if its been said on here or not but heres what ive figured out in my couple years of having car audio as a hobby.

1. ive got experience with a couple "good" shops in my area as well. basically both have shown me that if you arent willing to pay top dollar for their main brand (JL, ETC) then they really dont care about you. they will put their newest guy on the job and give you the run around if you have problems.

2. take the time to read a couple of these threads and learn how to do the stuff yourself. there is typically a bunch of guys on here that will help you along the way. you will learn its really not that hard, and then you know for sure whether its the installs fault or what is exactly wrong.

3. if you take the time to learn and do it yourself you will learn about a whole bunch of products that youve never heard of that will be 10 times better than what you have and will cost half the price.

hope that helps.

sounds like a bunch of kids playing Stereo Pro....

seriously just adding a 2nd battery will solve nothing....

if your alternator can not keep up with the system and

a single battery adding a 2nd battery will just add extra

strain on the already over worked alternator...

the 2nd battery will help till it gets run down then the problems will

start all over again

adding a capacitor will also add extra strain on the charging system

a cap should not be added to a system with a weak alternator..a cap

can draw large amounts of juice from a weakly charged system to keep topped up

you need to upgrade to the big 3 and add a high out put

alternator...this will take care of the dimming lights and electrical

problems

as far as the SHOCK from the vehicle....I had a Nova that did the same thing

and was never able to figure out why...if I touched any metal on the door

when getting out of the car it would give me a good jolt and it was not

static electricity...weird
