Disaggregation of Revenue [Line Items]
Revenue from Contract with Customer [Text Block]	(23) Revenue from Contract with Customers On March 1, 2018, the Company adopted ASC Topic 606, Revenue from Contracts with Customers, and all the related amendments (“ASC Topic 606”), using the modified retrospective method. In addition, we elected to apply certain of the permitted practical expedients within the revenue recognition guidance and make certain accounting policy elections, including those related to significant financing components, sales taxes and shipping and handling activities. Most of the changes resulting from the adoption of ASC Topic 606 on March 1, 2018 were changes in presentation within the Unaudited Consolidated Balance Sheet. Therefore, while we made adjustments to certain opening balances on our March 1, 2018 Unaudited Consolidated Balance Sheet, we made no adjustment to opening Retained Earnings. We expect the impact of the adoption of ASC Topic 606 to be immaterial to our net income on an ongoing basis; however, adoption did increase the level of disclosures concerning our net sales. Results for reporting periods beginning March 1, 2018 are presented under the new guidance, while prior period amounts continue to be reported in accordance with previous guidance without revision. Revenue from Contracts with Customers The core principle of ASC Topic 606 is that an entity recognizes revenue to depict the transfer of promised goods and services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods and services. We apply the FASB’s guidance on revenue recognition, which requires us to recognize the amount of revenue and consideration that we expect to receive in exchange for goods and services transferred to our customers. To do this, the Company applies the five-step model prescribed by the FASB, which requires us to: (i) identify the contract with the customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, we satisfy a performance obligation. We account for a contract or purchase order when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the product passes to the customer, which is upon shipment, unless otherwise specified within the customer contract or on the purchase order as delivery, and is recognized at the amount that reflects the consideration the Company expects to receive for the products sold, including various forms of discounts. When revenue is recorded, estimates of returns are made and recorded as a reduction of revenue. Contracts with customers are evaluated to determine if there are separate performance obligations related to timing of product shipment that will be satisfied in different accounting periods. When that is the case, revenue is deferred until each performance obligation is met. No performance obligation related amounts were deferred as of August 31, 2018. Within our Automotive segment, while the majority of the contracts we enter into with Original Equipment Manufacturers (“OEM”) are long-term supply arrangements, the performance obligations are established by the enforceable contract, which is generally considered to be the purchase order. The purchase orders are of durations less than one year. As such, the Company applies the practical expedient in ASC paragraph 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less, for which work has not yet been performed. Certain taxes assessed by governmental authorities on revenue producing transactions, such as value added taxes, are excluded from revenue and recorded on a net basis. Performance Obligations The Company’s primary source of revenue is derived from the manufacture and distribution of premium audio, consumer accessories, and automotive products. Our consumer accessories products primarily consist of finished goods sold to retail customers, while our premium audio products primarily consist of finished goods sold to both retail and commercial customers. Our automotive products are sold both to OEM and aftermarket customers. The majority of the products sold to our automotive customers are manufactured by the Company. We recognize revenue for sales to our customers when transfer of control of the related good or service has occurred. All of our revenue was recognized under the point in time approach for the three and six months ended August 31, 2018. Contract terms with certain of our OEM customers could result in products and services being transferred over time as a result of the customized nature of some of our products, together with contractual provisions in the customer contracts that provide us with an enforceable right to payment for performance completed to date; however, under typical terms, we do not have the right to consideration until the time of shipment from our manufacturing facilities or distribution centers, or until the time of delivery to our customers. If certain contracts in the future provide the Company with this enforceable right of payment, the timing of revenue recognition from products transferred to customers over time may be slightly accelerated compared to our right to consideration at the time of shipment or delivery. Our typical payment terms vary based on the customer and the type of goods and services in the contract or purchase order. The period of time between invoicing and when payment is due is not significant. Amounts billed and due from our customers are classified as receivables on the Unaudited Consolidated Balance Sheet. As our standard payment terms are less than one year, we have elected the practical expedient under ASC paragraph 606-10-32-18 to not assess whether a contract has a significant financing component. Our customers take delivery of goods, and they are recognized as revenue at the time of transfer of control to the customer, which is usually at the time of shipment, unless otherwise specified in the customer contract or purchase order. This determination is based on applicable shipping terms, as well as the consideration of other indicators, including timing of when the Company has a present right to payment, when physical possession of products is transferred to customers, when the customer has the significant risks and rewards of ownership of the asset, and any provisions in contracts regarding customer acceptance. While unit prices are generally fixed, we provide variable consideration for certain of our customers, typically in the form of promotional incentives at the time of sale. We utilize the most likely amount consistently to estimate the effect of uncertainty on the amount of variable consideration to which we would be entitled. The most likely amount method considers the single most likely amount from a range of possible consideration amounts. The most likely amounts are based upon the contractual terms of the incentives and historical experience with each customer. We record estimates for cash discounts, promotional rebates, and other promotional allowances in the period the related revenue is recognized (“Customer Credits”). The provision for Customer Credits is recorded as a reduction from gross sales and reserves for Customer Credits are presented within accrued sales incentives on the Unaudited Consolidated Balance Sheet. Actual Customer Credits have not differed materially from estimated amounts for each period presented. Amounts billed to customers for shipping and handling are included in net sales and costs associated with shipping and handling are included in cost of sales. We have concluded that our estimates of variable consideration are not constrained according to the definition within the standard. Additionally, the Company applies the practical expedient in ASC paragraph 606-10-25-18B and accounts for shipping and handling activities that occur after the customer has obtained control of a good as a fulfillment activity, rather than a separate performance obligation. With the adoption of ASC Topic 606, we reclassified certain amounts related to variable consideration. Under ASC Topic 606, we are required to present a refund liability and a return asset within the Unaudited Consolidated Balance Sheet, whereas in periods prior to adoption, we presented the estimated margin impact of expected returns as a contra-asset within accounts receivable. The changes in the refund liability are reported in net sales, and the changes in the return asset are reported in cost of sales in the Unaudited Consolidated Statements of Operations and Comprehensive (Loss) Income. As a result, the balance sheet presentation was adjusted beginning in Fiscal 2019. As of August 31, 2018, the balance of the return asset is $1,657 and the balance of the refund liability is $3,705, and they are presented within prepaid expenses and other current assets and accrued expenses and other current liabilities, respectively, on the Unaudited Consolidated Balance Sheet. We warrant our products against certain defects in material and workmanship when used as designed, which primarily range from 30 days to 3 years. We offer limited lifetime warranties on certain products, which limit the customer’s remedy to the repair or replacement of the defective product or part for the designated lifetime of the product, or for the life of the vehicle for the original owner, if it is an automotive product. We do not sell extended warranties. Contract Balances Contract assets primarily relate to the Company’s rights to consideration for work completed but not billed at the reporting date on contracts with customers. Contract assets are transferred to receivables when the rights become unconditional. Contract liabilities primarily relate to contracts where advance payments or deposits have been received, but performance obligations have not yet been met, and therefore, revenue has not been recognized. The Company has no contract assets or contract liability balances at August 31, 2018. Disaggregation of Revenue The Company operates in three reportable segments: Automotive, Premium Audio and Consumer Accessories. ASC Topic 606 requires further disaggregation of an entity’s revenue. In the following table, the Company's net sales are disaggregated accordingly for the three and six months ended August 31, 2018 and 2017:

Contract Balances

Contract assets primarily relate to the Company’s rights to consideration for work completed but not billed at the reporting date on contracts with customers. Contract assets are transferred to receivables when the rights become unconditional. Contract liabilities primarily relate to contracts where advance payments or deposits have been received, but performance obligations have not yet been met, and therefore, revenue has not been recognized. The Company has no contract assets or contract liability balances at August 31, 2018.

Disaggregation of Revenue

The Company operates in three reportable segments: Automotive, Premium Audio and Consumer Accessories. ASC Topic 606 requires further disaggregation of an entity’s revenue. In the following table, the Company's net sales are disaggregated accordingly for the three and six months ended August 31, 2018 and 2017:
