my passenger front speaker sometimes vibrates with bass on some tracks, so i think im gonna replace the front speakers

now this might be a strange question on here, but i have no amp, or any plans to change from the OE head unit or install any amps of any kind

ive been looking at a few component sets which dont have crossovers as my OE system has a tweeter behind the door mirrors so im thinking i can just swap each bit like for like

been looking at the following

Alpine SXE 1750S

30W RMS

Sensitivity: 91dB/W/m

Pioneer TS-170Ci

35W RMS

Sensitivity (1W/1m) 89 dB

Pioneer TS-H1703

50W RMS

Sensitivity (1W/1m) 91 dB

now the Pioneer TS-H1703 are the most expensive, can be had for about £65 online, whereas the Alpine are around £35-£40, but im wondering with the more expensive Pioneers being listed as 50W RMS, would my OE headunit be too underpowered to drive them properly, and maybe the cheaper Alpines might actually be better as they are possibly more of an OE replacement speaker, though all the ones ive listed are 'custom fit speakers'

its been a while since ive done any in car audio so my technical knowledge is getting a bit rusty

i changed my front ones in the ocy for jus a set of cheap Fli intergrators. obv u dont have the separate tweeter but u dont need it with these. the sound is dispersed well enough so it does sound like u have tweeters connected. As for power issues driving them, the standard hu output per channel is about 8w i think. usually some speakers specify a minimum input so as you get the best from them, as underpowering speakers can be as harmful as overpowering. I have a after market hu in atm runnin 18w per channel, but will be runing the front door speakers and my sub off an ammp when money allows it. gona prob do away with the rears altogether. recommended input for the spkrs i got is 70w and their peak is 210 think. so an amp running 50 w per channel on speakers shud do it right.

sorry, seem to have gone off one a random there, hope ive helped in some way msg bk if you would like any other advice. REH17

if the OE output is only 8w then im thinking maybe the Alpines or the cheaper Pioneers may be better suited

yer the lowest matched rms value of the speakers wud be best, however if like me u like ur music loud, and bass deep and true then go for something more powerful and made from real good materials. all depends what kinda music u like to listen to and at what volume.

Sure it's not your doors vibrating?

nope, no door vibration, screwed em in nice and tight BOOM!

Regarding speaker choice. What's the watt output on RNS510 with the sound system with 12 speakers. (Is there some amplifier inbetween?)

if i was putting an amp in etc id happily spend £150 or so on some front comps, but im not, and being driven off a low powered head unit wouldnt give me fantastic sound and may in fact do them some damage id have thought, would it not, please correct me if im talking rubbish here ?

see the pricier pioneer ones are they better speakers from spec, but at a 50W rms rating im worried they would be seriously under powered and may sound worse, or become damaged as a result ?

Money no object - Focal

Slightly cheaper - JL

That said, don't get hung up on sensitivity and freq response. Even the cheap stuff these days sounds very very good and pretty much anything will be an improvement. I'f you want to make the best of the upgrade, go to your local car factors and buy some bitumastic damping panels. They cost a fraction of Bread or Noise Killer and are can be moulded to the contours of the door inner. Be careful with placement thought ecause they stick like **** to a blanket and are there for the life of the car!! They are so cheap you have nothing to lose!

If it vibrates, then maybe it is looser than it should be? They are usually rivetted to the metal door carrier. Maybe just drill the rivets out, stick a layer of flashing tape or similar on the carrier and then nut and bolt the original speakers back into place? Epoxy the bolts into place and tighten the nuts down when it's set?

Or maybe it's the door card. Have they been removed at any point? The clips should have little rubber washers on them. If not, maybe that's adding to the vibration.

i recently had a fiddle and it is something in the door !

so ill be getting some dynamat in a few weeks and trying to solve it that way
