Description
Defined front speaker and treatment package
One original Focal IS BMW 100L stereo front component set with two drivers, two matched tweeters and its specified crossover filtering, plus one Dynamat Xtreme 10435 pack containing four 12 x 36 inch sheets, totalling 12 square feet (approximately 1.11 square metres). The material is cut to fit; manufacturer coverage for two standard doors is not a measured guarantee of full coverage on this vehicle.
No duplicate tweeters or generic speaker adapters are added. Verify the supplied mounting provisions and actual vehicle. Any missing tweeter mounts, wiring or additional parts require a separate assessment.
Exact vehicle and audio scope
Selected BMW 1 Series E87 five-door vehicles built 2005–2011, standard/base factory audio, front component-speaker positions only. This is not an E81 three-door, coupe, convertible, V2 or other BMW configuration. Premium HiFi, Top HiFi, Logic7, Harman Kardon, factory-amplified, modified or unknown systems require separate assessment; this is not a claim that every such system is incompatible. Verify original speaker impedance, connector, mounting and separate tweeter location. Underseat woofers and rear speakers remain unchanged.
This selects only the front speaker kit, not the complete multi-speaker system shown in a manufacturer configurator. Provide build date, chassis/body style, original audio specification and relevant connector/mounting photographs. Preserve supplied crossovers and all vehicle safety functions.
Installation assessment and precautions
Select Request an installation quote if you would like fitting assessed. This is a zero-charge request only: installation is not included, no appointment is booked and no free fitting is offered. Provide the vehicle and original audio-system details. Labour, access obstacles, trim removal, wiring, extra materials and any additional charges will be assessed, quoted and agreed before work starts. No fixed fitting time is promised for this vehicle.
No installation labour or fixed fitting time is included. A qualified installer must check depth, trim, glass travel, tweeter positions, impedance and wiring. Apply treatment to suitable prepared surfaces following the manufacturer instructions; never obstruct drains, window mechanisms, locks, cables, airbag equipment or service access. No complete soundproofing or measured performance improvement is promised.
The original headunit is retained; no replacement stereo, DAB aerial, camera or factory-function retention interface is included. Additional materials, mounting parts and installation are separately assessed and quoted. The zero configuration charge groups the separately priced products. The payable total includes VAT once; there is no package discount or lowest-price claim.
Base package price excluding VAT: £294.26 (supply-only). Optional extras are not included.
