2019 $150 SPL Challenge

It’s back!! And bigger than ever. In case you don’t know or don’t remember, some of us did this a few years ago and in general, it goes like this…
It’s an SPL challenge using only $150 worth of sub(s) and amp(s). New prices. Nothing else counts towards your budget. Not wood or batts or anything. Not even shipping! Just the subs and amps.
This time around there will be two divisions. Original flavor and the new “sub only” flavor. Where you get to spend all $150 on just subs. Classes will be trunk and everybody else. Standard Usaci rules apply.
There may or may not be prizes. I don’t know yet. I will update when I do.

Rules…(these are subject to revision as questions are answered, issues arise and clarifications are needed).
– “Sub only” means you get to use your whole budget toward your sub(s). All other rules apply. Note: for the sub only challenge YOU MUST BACK UP YOUR SCORE. This means that you will have to do at least two burps within five minutes of each other. The lower score will be the one that counts.
– Trunk- all equipment must be in the trunk and the seats must lock back into place.
– “Outlaw” metering is mic anywhere forward of the ‘B’ pillar and any combination of doors and windows may be opened.
– No gear forward of the pillar. And no “port scores”.

– You get $150 TOTAL to purchase sub(s) and amp(s). Shipping and/or taxes do not count toward the total.
– Only the price of subwoofer(s) and amplifier(s) count toward your budget. Amplifiers must be designed for mobile audio use.
– Prices must be readily available to the general public and for brand new equipment. No dealer pricing, no homeboy hookups, etc.
– Used equipment may be used provided that the competitor can prove the price of the equipment’s new prices come in under budget.
– Screenshots and/or receipts will be required.

– Competitors must provide video proof of scores. Garage scores are fine as long as the video is comprehensive enough to satisfy the R&E committee. These will be reviewed and scrutinized. And trust me when I tell you that R&E knows every trick in the book.
– Please keep in mind that this is supposed to be fun.

The challenge is now active. It has begun. All scores/videos must be submitted and/or posted by May 31st, 2019.
Any and all questions and concerns can be asked and addressed here and rules and clarifications will be updated as needed. I know I’ve forgotten something. And for anyone curious… I will be competing but I am excluding myself from prize eligibility.

  1. That sub is custom built by a recone company and sold as a complete sub for 150$ plus shipping. It’s not a Sundown SA
