Alpine Type-S SPS171A

Will this component set work for the front door? I currently want to use the factory amp, sail panel speakers, and rear speakers. I have an Alpine CDA-9833 head unit. I blew one of the door speakers and want it fixed pretty soon. I was originally going to do a whole system upgrade, but ran into financial issues. And yes, I've read and read the sticky and many different search results. It seems that no matter the subject, some say one thing and somebody else says another.

I am basically wanting to know if this setup would plug and play or not? If not, what would I need to do for it to work or is there a better quick fix?

yes, it will work.....how well will be up to you. I would just run new speaker wire from the 9833 to the new alpine speakers

NBM7278

Do you mean bypass the amp for the fronts? I have no problem running new wire if it'll help. The local audio shop said that the head unit could power the components, but it wouldn't sound as good as the original speakers. They could just be trying to conjure up some business though.

before i had an amp for my fronts, i ran new wire to the speakers in the door fromt he deck.........they sounded like *** from stock amp

and they are partially correct, those speakers need more than the 20 watts (or so) rms from the deck, but it is still in the power range

NBM7278

The deck puts out 26 watts rms. I'm sure that's peak rms though. The speakers need 50 watts rms to work nominally. Will this even sound as good as the stock speaker setup? If not, I may have to look further for speakers. I don't want to completely waste the money for now.

im sorry, you are correct the 9833 is 26 rms per channel

but the speakers, their recommended power range 8-50 watts RMS

NBM7278

Do you think it's worth getting this setup to hold me off until I can amp them? Again, I'm trying to stay in the 200 or less range and not have to worry about the speaker blowing again in the near future. I actually like the stock setup for daily driving, but I've replaced enough sail panel speakers to drive someone nuts.

you have a PM

I see no reason you can't use your Monsoon amp with these. You'll only need the crossover for the tweeter, if you do hook the woofers to the amp.

If you hook them up directly to the head unit, It should sound just fine. The midbass freq's just won't be as loud at the same volume setting as it would running thru the amp. And if the rear channel is still amped, you'll have to adjust the fader forward to compensate.

NBM7278

Alright, is this correct then.
Alpines straight from the head unit or from the amp with the crossover

Either one would work then? Once I get the door panels off, it'd be easy enough to try both ways and see what sounds better. As long as they'll work, then I'll probably go ahead and place an order for them this weekend.

I understand the theory of crossovers (I work in electronics/engineering with radio frequencies), but I haven't actually had to hook them up before.

HiTechGent

You'd only wire the woofer to the Monsoon amp as it's low-passed internally. Either way, the tweeter will need to be run off of the head unit using the crossover.

Alright then, I'll probably be posting up again once I get some speakers in hand. I think I've got it though. Thanks.

You guys making this too complicated... Why run new wire if only the HU and door speakers are being replaced.

Get rid of the monsoon amp. Find a wiring diagram for the fat 32 connector harness, and just jumper the appropriate wires so they loop thru the harness. The factory wiring is quite sufficient to handle the power output of a HU.

NBM7278

Haha, complicated is an understatement for most car audio (if you're a newbie to it all).

Here's a quick question to add to the list...
I keep reading about the infinity 2 ohm speakers. Most of the people talking about it are the camaro owners though. On my bird, would they be better for the front replacements or not?
