super noob audio question!

[KillerTofu]

hey guys.

currently got an eg hatch and just curious about some audio stuff.

for the rear brackets in the panels, would i need to do alot of modifying to fit 6x9s?

and with subs..

im assuming a 2 channel amp means 2 outputs, suitable for subs?

if thats right, would i be able to use just one of the outputs for now (till i can afford another sub) to power my single? then later use both outputs?

ta in advanced!

with regards to the AMP, yes you can only use one channel for the time being.

how much watts is your amp? since its two channel im guessing its a MONO amp which is what you need for subs.

i got a Alpine Type R sub in my sisters car which is 1500watts/500 rms. and the amp is mono block 1000watts/300rms kenwood, and its underpowered

[KillerTofu]

i haven't baught an amp yet as i was unsure, i've just got a 12" clarion sub which is a super powerfull 250rms.. lol

not sure what amp i should buy? cause i don't want to waste money on an amp that ill use for now then have to throw away, but then i don't want to have a terrible amp for when i do upgrade, and providing i upgrade, i'd then have to get a weak second sub, or straight out get two new subs.

no idea what to do !

[dc2r-0636]

hmmm unfortunately quality amps are not cheap. kenwood is in the same catergory as like sony xplode n shit. good bang for buck tho.

http://au.kenwood.com/Car_Entertainment/Power_Amplifiers/KAC-9105D this is 500rms. will be sweet if you could get one alpine type r in factory ported box or a JL audio W7 paired up with it. or another clarion sub that you already have

[KillerTofu]

ok so i've had a change of plans, and i think im just gonna get a small 12" sony xplod sub, just cause its cheap, and i think itll be loud enough to feel/hear in my eg anyway.

it has 300 RMS.

so what amp do you recomend?

thanks alot for the help!

[dc2r-0636]

i see. the model before the one i linked you should be good. its 1000watt and 300rms so just perfect

A 2 channel amp is not a MONO a MONO is what you will need to run 1-2 subs to their full potential. I had a 4 channel amp, 2 channels running a 12" sub and the other 2 channels running to front splits. The sub sounded underpowered, didn't sound like a sub. So get a MONO to get the best sound from your sub(s)

i got a two channel amp and its MONO.. my sub is dual voice coil, so in total there are 4 wires (2positves and 2negatives)

ofcourse your sub was underpowered when your running it off a 4channel along side 2 speakers rated at like 200w..

[1996_EK_Civic]

your 2 channel amp is most likely bridged to act like a mono-block.

to the OP if you want to run twin subs in the future, get a half decent 4 channel then you can bridge the channels, and if you dont run twins you can still power 2 of you speakers off the amp

[KillerTofu]

For now I'm just gonna run the one sub, which I just baught

I'm hoping 300 rms will be loud enough ? Then again it's going in a hatch so I think itll be fine.

So my best option for budget is to bridge a two channel that can put out 300rms correct ?

Thanks alot guys!

[dc2r-0636]

its not bridged at all.
all mono block amps are 2 channel... MEANING you can run 2 subs off the one amp. so it has 2positive terminals and 2negatives.

[GaDgeT-CRX]

There is a bit of conflicting info being provided here..

An amp designed to run a sub should be 1channel and mono. Should also include a gain control and low pass filter.

You can bridge a 2ch amp to run 1 sub, or a 4ch amp to run 2 subs, but amps designed to run mid/ high speakers usually feature a high pass filter and dont behave the same as a mono amp designed to run a sub.

Best advice is to get 1 decent quality sub, and decent quality amp.. sad to hear you have already purchased the xplod, I wouldn't recommend them.

Try and get yourself a monoblock amp to run the sub, higher the RMS rating, the less work it has to do to produce a clean signal.

my point is, here is my mono amp with 2 channels... ( +, - , + , - )

fair enough i take back my comment

[GaDgeT-CRX]

id check your wiring there bro.. the 2ohm dual sub connections are not meant to be bridged. check out page 4 of the manual http://images.kenwood.eu/files/prod/964/5/KAC-9104D(EN).pdf

how is it bridged ? look in the photo how the wires are. same as the diagram

[GaDgeT-CRX]

not the same.. sub 1 should take 1 and 3, sub 2 should take 2 and 4

[dc2r-0636]

not the same.. sub 1 should take 1 and 3, sub 2 should take 2 and 4

ive only got ONE sub connected bro (dual voice coil) alpine type r

[GaDgeT-CRX]

ahh.. my bad.. thought u had 2 subs.. 2ohm + 2ohm into dual coil, all good :)

[KillerTofu]

NOW YOU GUYS GOT YOUR SHIT SORTED! hahaha.

anyone selling an amp that can put out 300rms x 1 4 ohms?

need something super cheap , so poor!

[1996_EK_Civic]

maybe try ebay or gumtree for cheap amps. my mate picked up two cadence amps from ebay for like 130 shipped

[Bludger]

nice title

[arverson]

"super noob audio".. you got that right!

[dc5.taiger]

from my experience 6x9 didnt fit in the factory rear slot, it just didnt fit.
if your running a sub its better off getting 6.5" speakers and let ur sub handel the bass

[WarrenM]

For now I'm just gonna run the one sub, which I just baught

I'm hoping 300 rms will be loud enough ? Then again it's going in a hatch so I think itll be fine.

Unfortunately, no one has asked you the important questions and told you what you need to know.

Firstly, have you purchased the Sony 12" in a sealed box or a ported box? Both are available and have very different output levels for the same input power. In a sealed box, it has a sensitivity of about 85 dB at 1 watt at 1 metre. That means that at 300 watts, it will put out about 110 dB. I don't have specs for the speaker in a ported box, but I suspect that it will put out maybe 3 or 4 dB more for the same power.

If you have no need for this much output, and never plan to drive the sub that loud, then you do not necessarily need to purchase as large an amp. On the other hand, if you buy an amp which cannot put out enough power to drive the sub loud enough for your needs, you are likely to destroy the sub and maybe the amp in the failed attempt to get enough volume out of the system.

As some people have already indicated, most good quality two-channel amps can be bridged to run a single much more powerful channel.

As for 6x9 speakers in the back, it does seem a little pointless to seat high volume full frequency speakers behind you, rather than in front of you. I would go instead for good quality speakers in the front doors, which will tend to offer you a more satisfying musical experience.
