Dumb Question Thread!

Getting a new sub and amp. Looking at a 400w dvc sub wired to run 2 ohm. The amp i had been eyeing up does 500w at 2 ohm. Will this cope alright? Had a guy at an audio shop in tga saying it\'ll run too close to the amps max too often and wear it out prematurely, there any truth in this??

[boon]

Haha, wtf.... it\'ll be fine.

[Andy_Mac]

That\'s what i thought. Seemed weird, guess it kinda makes sense if you were maxing the sub out the entire time. Would distortion go up closer to the amps max maybe? Like give it a hiss or something?

depends. assuming those ratings are RMS, you should be fine.

Most subs these days are sensitive enough that listening to them at 400-500W continuously would be bad for your ears.

Just make sure you set your gains correctly so it won\'t clip at loud peaks in a track.

[Andy_Mac]

Yea rms. it won\'t even be extremely bass heavy stuff i\'m listening to, just want to fill out the sound a little bit better. Will going to a higher wattage one reduce the chance of clipping?

My problem is the next step up in the range jumps up to 800w so super overkill and $200 more.

Had a couple of screws come loose and go walkies on the left side of my bumper (BG gtb)

Have some at home I think, but I need to replace the left side engine cover/under guard pieces since chch road wasted it. Will find some this weekend.

Question is, do I have to remove bumper to replace these? Is this easy? Just remove lights and so forth? May seem obvious but would rather not fuck anything tbh

Looks like I\'m getting 2-pots + S401 backing pates (i.e no adapters will be needed to fit the 2-pots on my BH5 ). Has anyone got a tool to press the hub out?

Anyone got this tool in Auckland? :

any other "driveway" methods of removing the hub?

[lachlan]

surely any claw puller on the drive flange would work ?

or a bfh

so went to start the car this morning and no go plenty of power in the battery even hooked up another one to the jumper leads was trying to start just no igition so i think my starter motor is stuffed?

is there anything else it could be?

it was working last night when i put it back into the shed then this morning no go and of course i was already running late for work.

[Roo]

Does it turn over?

[Johnnynz]

If its just giving one solid tick give the starter motor a gentle(ish) tap with a hammer and try again.

Amps wired up correctly? lol

hope so

when you turn the key you get rerererere then again rerererere nothing why won\'t you start.

Logical thinking tells me its the starter if jumpers don\'t work.

Yup but have someone try to start it while you beat it. Or rip it off and bench test. Also try a screwdriver across the terminals.

[QRAF]

can you get to it from underneath?

[Guest]

Easier from top side should be enough room to the side of tmic.

[QRAF]

yeah not so much with my tmic and my tmic is a bitch to remove and put back on.

So it\'s turning over just not firing?

[QRAF]

yeah and smells of gas after trying so i know i have gas

[Rosssub]

Then your Starter Motor is sweet. Can you hear the Fuel Pump Priming when you turn the Ignition on?

[GC8E2DD]

Does it go if you crash start it?

[max.]

Also sounds like plugs might be fouled if you can smell fuel... my 2c

Edit - Probably worth checking that you are getting vaccum whilst cranking as well.

Found this - http://www.linnbenton.edu/auto/perform/no_start.html

Seems you have ruled out the battery being flat but might be worth chucking a volt meter on there and seeing what voltage you are getting when cranking also.

Starter motor seems fine so would a crank angle sensor stop it from starting as that\'s what the ecu is saying it\'s faulty
