you wont tip over unless your making some crazy fast turns. it would be like driving with your van full of people. itll be a little slower, maybe you press the brakes a little harder but nothing to worry about.
i think the frequency effects it more. some one could have 4 18"s doing 155db but at 70hz they dont move a ton of air. but the same subs at only 150db at 30hz would do a crazy hairtrick.
he is wrong. you will get 1ohm. its actualy series/parallel. its looks like you are going to wire them right. little hard to tell from the pic but it looks good.
i think it depends on the car. mine had the lights dim with almost no voltage drop and about the same power you have. where is your volt meter connected to? mine is hooked up to the sub amp and it shows dips way below what a meter on the battery will tell you.
my friend put my car into a curb his 1st time driving in the snow. he got off the highway like it was any other time and he's one of those guys that stops short. thank god we didnt go into the intersection or into the light pole. just bounced off the curb and fucked up a rim.
ok... now i want a "how to" on eating that fucker. i thought you could order as large of a burger as you wanted from in and out? i heard shit about a 10x10 some one ordered...
you checked behind the HU too? make sure you really double check what these guys tell you to check. a lot of times people just think something is fine only to find out later that it was the problem and they never really checked it.
