Head unit and sub question

[19esz398]

Went from no cd player to a Kenwood KDC MP-7028. It's amazing... the best part is it measures accelerating and cornering G-forces. Its also got a display of a car that turns when i turn.. haha i love it. also got two Memphis M-class 5 1/4 in. for the kicker panel speakers which help hearing music with the top down. Anyways does anyone have suggestions of what size/kind of sub to go between the two seats

If you get a w6v2 or a W7, it will hit so nicely. I dont know what size that would be, but definatly look into those 2 subs with a proper JL amp for the size of the sub

JL is so expensive, get it if you wanna blow your money. Infinity Kappa perfect is nice if you want something comparable to a W7. Its even a little softer sounding....

go w/ JL w3, great subs and u can find em new for around 150 or so

Just wondering what the head unit looks like. Cna you take a picture and show that car your talking about.

JL Audio are great subs but after blowing 2 in the past I'll stick with Alumapro
get an Alchemy and pump it with a good 300 watts and you'll be very happy, great subs and cheaper than a W7, I'll take an aluminum cone anyday

yeah i'll take a picture tomorrow... has anyone heard of the trubase 8 inch... i heard it requires 500 watts to even run... gimme your input

You just hinted at the problem with most modern subwoofers: very inefficient. A massive 8-inch woofer can easily have half the efficiency of a 10-inch or 12-inch woofer due to the small radiating cone area and excess moving mass.
A lighter cone assembly with a precision motor typically will produce high SPL's with half the power. At the SLAP Grand Nationals last fall (a major dB drag event), the top finalists in one of the categories had (4) 15-inch JL subs and 10,000 watts pitted against another car with (4) Alumapro AlchemyRX 12-inch subs and 8,000 watts. The JL car got second place for the show with 158 dB. The Alumapro subs beat that with 168 dB! A huge first place steal. That's 10 TIMES the acoustic output with smaller subs and less power!
Granted, this is not typical comparisons, but it illustrates that you do not need huge amplifiers/multi batteries/new alternators to achieve excellent bass performance. Just good sense when selecting subs and enclosures.
