IDBL Class For Pickups

DooMRR · Postby **DooMRR** » April 22nd, 2011, 2:38 am

I don't have access to the rules and I want to know what class I will be place in if I have a single 8" sub. It will be used in a pickup truck (Mazda B2500) and resting somewhere on the back seat. The amp is behind the back seat and everything in the van is stock including the alternator.

Also, if I add a second battery and rest it on the floor behind the driver/passenger seat, will that change the class?

stock, your enclosure must be mounted to the rear wall and be under 25inchs in height and if on the seat under 20inchs in depth

Or advance nw

Back when I started to compete in SPL, stock category world records were held by pickups in Bangkok.

Few questions about this:
"Mounted to the rear wall" as in up against the back SEAT right? Also, I'm guessing taking out the back rest is not an option for Stock class?

What about a second battery in the back on the floor behind the driver or passenger seat?

This just made my day. Didn't think pickups were SPL friendly.

You can consider folding the rear seat down and (temporarily) mounting the enclosure to the back wall.. not sure where that would put you in the rules though..

^^ Not allowed in stock class

cvt_xoxoxoxo, quoted from the rule book

The subwoofer enclosure must be mounted to the rear wall of the cab and no taller than 25 inches in height (see equipment criteria for Stock Division) from the cab floor. The enclosure cannot impede the full operation of the seat and seat travel must remain intact. EXTENDED (KING) AND CREW CAB TRUCKS (Compact and Full Size) - The subwoofer enclosure can be mounted in the rear ―seat‖ or passenger area of the vehicle, but the enclosure depth cannot exceed 20 inches. Additionally, the enclosure must be mounted to the rear wall of the cab and no taller than 25 inches in height from the cab floor. The enclosure cannot impede the full operation of the seat and seat travel must remain intact.

No blow-thrus, the only difference I can recall with today's rules was that back in the day, they used to store their amps, wiring and batteries in the stock cargo location i.e. the tray. I don't think that's allowed today.

Advanced NW it is then. I'm not really desperate for a trophy (although it would be good to win something for my effort). Just want to see what score I can make with it. Can't fit any sub behind that seat because it is just too small. "Hopefully" I will be in the next show. The enclosure is one thing, the vehicle is another. Don't know how well it will work for SPL.

Thanks for the feedback...

^^ If the 4x2 and the 4x4 is the same cab then the left maybe louder.

I know the rules have changed since last time I competed. Can one use a laptop as a head unit to send an input to the amp? (Touch screen doesn't work well for SPL)

3stagevtec · Postby **3stagevtec** » April 28th, 2011, 2:58 am

or can a laptop be used to control the head unit? such as laptop headphones amp output to deck..

Postby SR » April 28th, 2011, 5:50 am

source unit must be 12 volts

usb stick with iasca idbl cd can be used if its available from iasca

a laptop will not be allowed to be used as the source
