<![CDATA[speaker loudness]]>I put in a new aftermarket speaker in the front door of the sentra today....I have one new one and one old one now....my question is why does the factory one have like twice as much bass? They are the same size, and the new one handles 100 watts. Is that why? Bass doesnt kick in until later?? Does it matter that I have one factory and one aftermarket? Any ideas, or are aftermarket speakers just like that?

The point I'm getting at here is that with the advances in technology of the past 10 years there are literally hundreds of resources available to help you build and design a kick ass stereo system. My favorites are the Loudspeaker Design Cookbook, LEAP enclosure modeling software from LinearX, LMS from LinearX, and my Mobile Dynamics coursework books.

Another tip for those of you contemplating competition (non-SPL) is use the least amount of speakers you can for sound quality. A good pair of 6 1/2" coaxials in the kickpanels and a pair of tens in a sealed enlcosure in the trunk might win you more than you'd ever imagine.

show off 😛

The factory speaker had a metal plate on it that made the oval speaker round, so now the aftermarket oval speaker has a gap on top and bottom. Anything I can put in there to help out? And tjamz, u just talking about switching the pos and neg on the speaker right?

to me... the way that sound travels just kind of seems like common sense, difficult to explain

A must read for all aspiring speaker system designers IMHO.

It could be that the aftermarket one is crossed over internally (or even externally) to block the lower frequencies. Another thought is that it may not be exactly in phase w/ the OEM unit so the bass seems diminished on that side of the vehicle due to cancellation (not likely, you'd probably notice this happening in both speakers, rather than one). Another thought, is this a "premium" OEM system (BOSE, Infinity, etc...)? Sometimes they have matched drivers to work w/ the crossovers in the OEM amplifiers, for example a crossover that is designed for the 8 to 16 ohm OEM speaker will be several octaves off for a 4 ohm speaker. Its also possible that the aftermarket speakers didn't seal to the door as well as stock did and therefore the rear wave is cancelling out some of the bass frequencies due to that. You could try simply switching the polarity on the pioneer unit (switch the posi and neg terminals around) as this MIGHT have a small affect on bass and/or imagining.

And I would rather buy subs and amp those and then just turn up the treble on the in-car speakers rather than amp the in car speakers.

And Thats what I was guessing about the watts...thanks for the info.....would it make a difference if I put in both new speakers? I wouldnt think that it would but you never know...

Your old speakers are able to reproduce the lower frequencies better than your aftermarket speakers. It's about how the speaker is designed. But you will also note that over time (and as it gets warmer out) the upper and lower frequencies will continue to improve out of your new speaker.

your radio is probably putting out... 10 watts rms (constant) to the factory speaker which is rated for 8-12watts rms. however, the aftermarket one is rated for 40-60 watts rms (peak 100). this means your factory speaker is operating more in it's efficiency range than the aftermarket one. make sense? if i remember everything correctly from when i was into stereo equipment...
