Alpine SPS-400

Bought these as rear, or "fill" speakers in my '35 Ford Pickup that is a Street Rod. Needed the small size, but also they needed to be able to handle the power from the Alpine amp. I had to run the amp because the exhaust and engine on the street rod is pretty loud. We mounted these behind the headliner, and the slim fit worked great! For the application I'm using them on, they work excellent. Not a lot of bass, but they're mounted only about 12 inches from your head, and I'm not running a lot of power to them. If you need a small speaker that will handle a medium amount of power, I would recommend these. Sound is smooth and full.

Great Speaker

it has nice clean highs and it hits, i have it hooked up to a 50watt 4-channel amp and the bass that comes out of it makes you think its a 6x9. great price and great overall speaker a great buy

They're great

I installed these in an 87' Toyota pickup as well as an Alpine deck.
Just 4" speakers but man they pack a bit of a punch. My old ones used to crackle and pop at over volume 5 on the alpine, these ones don't crackle or cut out at all.
Cons:
I managed to break a connector pin for one of the wires off the speaker itself, so i ended up soldering the wire to the speaker. I suppose it was just manhandling, and was more human error.

Nice speakers, great price

Ok they are 4" speakers so they aren't going to pump out a lot of bass, but they are great on the mid and high range. The price seals the deal. If you are looking for small speakers, these are the way to go.

Great speakers for the price

I've had these for about 6 months now and they perform well, especially for the price. They produce nice clear sound and decent bass. I am currently running an external subwoofer so don't have deep bass running through them, but they've handled everything else without distortion. I'd recommend them for anyone looking for a nice set of replacement speakers. I plan on hooking them up to an amplifier soon and think they will sound even better then. The only thing I wish is the tweeter was more powerful, but I think I am just used to my previous component tweeters which were a little more powerful.

Good value

Good buy for your buck!They can handle a good amount of power without distortion,can get pretty good mid bass for such a small speaker and have very strong and clear highs,sometimes too strong!The only weak point is the way they reproduce the mids - around 500hz the response is not that good,may be cause they are too soft . . . Any way,good overall!
