replacing stock front speakers with Alpine SPR-17ls components

anvle · Apr 15, 2007

Hi All,

i'm a novice when it comes to car audio wiring so any help is truly appreciated. i've a 2001 GT with stock speakers & HU. just received an apline spr-17ls componets speakers and i'm planning on replacing front speakers with it. i don't have any $$$ for amp right now and don't want to pay bestbuy for installation.

i removed door but don't know how to go about wiring. alpine spr-17ls has a 2way crossover and instructions tell me to connect tweeter and speakers to crossover but from there i'm pretty clueless... How do i wire spr-17ls using existing speaker & tweeter wires? found instructions for celica on teamcelica.com but i'm still stuck at wiring. please help....

hmm you need an amp. simple.. 1) its the only way to wire it correctly 2) your blow them from underpowering em.

thanks for the quick reply... if i get an amp do i need a new head unit also since stock HU does not have an amp output?

find one. make sure the amp can do atleast 70 watts @ 4 ohms though.

02celica · Apr 15, 2007

You won't ruin speakers by underpowering them. It is always good to have more than enough power though.

SpikedCola · Apr 15, 2007

^^ He's right. The only thing you can ruin by being underpowered are subs.

02celica · Apr 15, 2007

^Are you both sure? i thought if you underpower or overpower any type of speaker that it will damage them?

SpikedCola · Apr 15, 2007

Normal speakers (component/coaxial) arent as picky, because they have little to no excursion, compared to a sub. Its probably not good to power a 50w speaker with a 5w amp, but it wont necessarily hurt it, in comparison to a sub.

Thats what Ive been told, anyways.

02celica · Apr 16, 2007

so can you power like a 50 watt speaker with a normal headunit that puts out so 20w rms?

SpikedCola · Apr 16, 2007

Right. You wont get the full potential of the speaker, but Id do it to mine, so I dont see a problem with it.

02celica · Apr 16, 2007

so do you just cut the stock speaker wire then run that to the crossover? then your own wire from there?
