i drive an opel astra. 60A is the biggest alt available :(

the fs of the btl is 31 hz whereas the l7s fs is around 26 hz.

ill probably go with the l7s.

Opel is part of GM. I bet you you could cram the alt off another vehicle in there.

I would take the BTL personally, it'll take more power than those L7's combined any day. But with only a 2610 to power it it's a tougher decision. Probably the L7s I guess...

I was a die hard kicker fan for years, but they are now made in China so they loose my vote. I have run and currently still have an 06 l7 15, but I don't run it any more. I have moved on to speakers that I can fix if they blow, Kicker now just gives you money towards a new speaker and it isn't much. Look into DC or some other brands before you make your choice. Just my 2 cents.

2 15"s Re-coned with a Custom re-cones with DD 9500 coils, Rockford Fosgate T1500-1bd, Designated Aux. 190 amp Alt@ 15.5 volts, Duel High Rate Aux. Batts. Doing 143+'s (current box and subs haven't been metered), 1st place in 129.9 Bass Race and a 2nd and a 3rd in NW DB Drag in the last two shows. Only gone two 2 show total thought, so not to bad

i already considered 2 15 btls but i would need to run at least 4 kw rms. to run such a setup properly would cost ~ 1000$ more than to run 2 15 l7s.

maybe in a few years ^^ im still student...

and i think the btls would just gain 3-4 db more.

ya i hear ya man. thats why i have the setup i do. im a student too and money is tight all the time. i just got a healthy tax return and blew it all on new audio shit haha.

and as far as 10 cu ft vs 12 cu ft i honestly couldnt tell you. ive only heard mine in the 10 cu ft. but im sure if you tune the port right it would sound pretty good.
